Summary of changes from v2.5.41 to v2.5.42
============================================
<bcrl@toomuch.toronto.redhat.com>
v2.5.31-aio-nohighmem.diff
- cleanup aio highmem handling, make it faster
<aia21@cantab.net>
Add functions for searching for an inode in icache and getting a reference
to it if present - fs/inode.c::ilookup() and ilookup5(), mirroring the
iget_locked() and iget5_locked() function pair. Also add two internal
helpers ifind_fast() and ifind() respectively which will later be used
by iget_locked() and iget5_locked() to do the search, too.
<aia21@cantab.net>
Cleanup: Convert fs/inode.c::iget_locked() and iget5_locked() to use
the new ifind_fast() and ifind() helpers, respectively.
<bcrl@toomuch.toronto.redhat.com>
correct return value from aio_complete on sync iocbs
<bcrl@toomuch.toronto.redhat.com>
update ns83820.c to v0.19
<agrover@groveronline.com>
ACPI: Replace ACPI_DEBUG define with ACPI_DEBUG_OUTPUT (Dominik Brodowski)
<rz@linux-m68k.org>
Move beeping and sysrq to input layer on m68k.
Add an m68k beeper input module.
<vojtech@suse.cz>

Input layer now handles those devices.
<bcrl@toomuch.toronto.redhat.com>
sync iocbs need to actually wake_up_process the waiter (as spotted by Suparna).
<jdike@uml.karaya.com>
A number of bug fixes from UML 2.4.19-6 -
Fixed the net crash seen when slab debugging is enabled
Fixed PROT_NONE
Fixed the 'tracing myself' bug seen on umlcoop. This was caused by
a number of SIGALRM handlers nesting on the idle thread stack because
the system was busy enough that UML couldn't clear one before the
next arrived.
<jdike@uml.karaya.com>
Removed from user_util.h the declarations that are now in time_user.h.
<bhards@bigpond.net.au>
Better naming for USB input devices that omit the manufacturer name.

Add support for PS/2 Active Multiplexing Spec, updates for PS/2 mouse
and keyboard handling - proper cleanup on reboot, allow USB-emulated
AT keyboards, option to restrict PS/2 mouse to generic mode.
<khaho@koti.soon.fi>
Make Logitech Desktop Pro (wireless keyboard & mouse) work with all buttons and wheel.
<vojtech@suse.cz>
Update Wacom driver to 2.4 changes and changes from Ping Cheng of Wacom.

<agrover@groveronline.com>
ACPI: Fix thermal management and make trip points R/W (Pavel Machek)
<agrover@groveronline.com>
ACPI: Allow handling negative celsius values (Kochi Takayoshi)
<vojtech@suse.cz>
Accept 0xfa as an "OK" result code for AUX TEST cmd in i8042.c.
This makes mouse work on certain notebooks.
<bcrl@toomuch.toronto.redhat.com>
create support for iocb kicking, where a retry operation gets triggered in the mm
context of the submitter to allow the use of copy_*_user.
<agrover@groveronline.com>
ACPI: Add another cast to Bjoern's MADT walking fix to silence warning
<agrover@groveronline.com>

<jdike@uml.karaya.com>
Small changes to bring UML up to date with 2.5.40.
<jdike@uml.karaya.com>
A set of small bug fixes brought over from 2.4.19-8.
<jdike@uml.karaya.com>
A bunch of network updates from 2.4.19.
Added the pcap transport, which makes a pcap packet stream look
like a network interface inside UML.
Lifted the limit on the number of network interfaces.
Cleaned up and simplified the transport interface.
<jdike@uml.karaya.com>
A small network bug fix from 2.4.19-7.
<jdike@uml.karaya.com>
Updated defconfig with CONFIG_UML_NET_PCAP.
<jdike@uml.karaya.com>
Back out a piece of the last merge which didn't apply in 2.5.
<jdike@uml.karaya.com>
Fixed a bit of the last merge which I messed up.
<agrover@groveronline.com>
ACPI: Interpreter update to 200201002
- Fix problem where a store/copy of a string did not set string length properly.
- Fix ToString operator
- Fix CopyObject not updating internal node type
- Fix a memory leak during implicit operand source conversion
- Enhanced error messages for namespace lookup problems
- Revamped Alias support
<jdike@uml.karaya.com>
Fixed a build bug with CONFIG_UML_NET_PCAP.
<jdike@uml.karaya.com>
Changed my mind about having CONFIG_UML_NET_PCAP enabled by default
in defconfig. This would cause the default config to break on
any system without libpcap, so disabling it by default is better.
<jdike@jdike.wstearns.org>
xor.h was created as asm-um/xor.h rather than include/asm-um/xor.h.
Fixed.
<bcrl@toomuch.toronto.redhat.com>
queue descriptor io errors instead of returning them from io_submit
<paulus@samba.org>
PPC32: Reorganize the files for the IBM 4xx embedded PPC processors.
This moves the 4xx platform-specific files into a new directory,
arch/ppc/platforms/4xx.
<vojtech@suse.cz>
Add japanese Set 3 scancodes to atkbd.c
<bcrl@toomuch.toronto.redhat.com>
adapt aio kick changes to ingo's work queues
<bcrl@toomuch.toronto.redhat.com>
buildbug.diff
<jdike@uml.karaya.com>
I forgot to add include/asm-um/topology to the repo.
<paulus@samba.org>
PPC32: Move a couple of 4xx-related files around.
<paulus@samba.org>
PPC32: Rename sigcontext_struct to sigcontext, and use sig->siglock.
<paulus@samba.org>
PPC32: Use prepare target to make the assembler offsets header file.
This also puts the file in include/asm-ppc/offsets.h rather
than arch/ppc/kernel/asm-offsets.h. This changes PPC to do things
similarly to other ports, and makes make -j work reliably.
<paulus@samba.org>
PPC32: Add the kallsyms section to arch/ppc/vmlinux.lds.S.
<geert@linux-m68k.org>
Please apply this small clean up, too:
- Kill unused variable and end-of-line whitespace.
- s/M68K/M68k/
<paulus@samba.org>
PPC32: fix in_atomic; PREEMPT_ACTIVE set doesn't mean atomic.
<aderesch@fs.tum.de>
Increase the resync timeout for serial mice, and fix MZ wheel direction.
<paulus@samba.org>
PPC32: put the _right_ asm-offsets.c in.
<paulus@samba.org>
PPC32: fix the last sigcontext_struct, missed previously.
<vojtech@suse.cz>
Fix LAlt-RAlt combination on AT keyboards (generated "unknown scancode" message).
<vojtech@suse.cz>
Make NR_KEYS be (KEY_MAX+1) so that keybindings
can be set for keys over 128.
<vojtech@suse.cz>
psmouse.c: ignore the sync bit to make slightly non-conforming devices
work.
<bcrl@toomuch.toronto.redhat.com>
fix missing list initialization in aio context creation
<yoshfuji@linux-ipv6.org>
net/ipv6/addrconf.c: Use prefix of 64 for link-local addresses.
<marcel@holtmann.org>
[PATCH] Make it possible to compile in the Bluetooth subsystem
..and minor() cleanups
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Call scripts explicitly via sh
Instead of recurring problems with non-executable permissions on
files in scripts/, just call them as "sh <script>".
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Fix drivers/scsi/aacraid/Makefile
(by Sam Ravnborg)
<paulus@samba.org>
PPC32: Add kallsyms support in stack tracing functions.
<paulus@samba.org>
PPC32: fix arch-level tid handling.
This makes sure we clear the user_tid in copy_thread, and that we
don't pass a bogus tid parameter in sys_clone when the CLONE_SETTID
and CLONE_CLEARTID flags are clear.
<paulus@samba.org>
PPC32: Add might_sleep() calls to down and down_interruptible.
<paulus@samba.org>
PPC32: change the pmd macros to allow us to support large TLB entries.
<johannes@erdfelt.com>
[PATCH] USB: Trivial MAINTAINERS update
<david-b@pacbell.net>
[PATCH] usbtest: mo'betta devices, control tests
This updates the usbtest driver:
- Supports more devices for the basic i/o tests,
using full speed ez-usb firmware (and usbtest
tweaks!) provided by Martin Diehl.
- Adds another test case, which issues control
messages to devices. There will be further
updates in this area (control queueing, and
likely improving usbcore api coverage).
- Adds a "generic device" mode where vendor
(and optionally product) ids can be given as
module parameters. Those devices can be used
for testing control traffic.
<greg@kroah.com>
[PATCH] USB: fix ctsrts handling in pl2303 driver.
Thanks to the prolific engineers for pointing this out to me.
<jdike@uml.karaya.com>
Updated initializers in the block driver.
Fixed a process exit bug.
<jdike@uml.karaya.com>
Updates to make UML build as 2.5.41.
Applied Oleg Drokin's task --> work patch.
Fixed the Makefiles to accomodate the fact the kbuild doesn't cd
into subdirectories any more.
Got rid of some compile warnings.
<acme@conectiva.com.br>
o Appletalk: convert some spinlocks to rwlocks
- Remove uneeded #ifdef CONFIG_SYSCTL
- Make __init strings __initdata, saving some more bytes after init.
<acme@conectiva.com.br>
o IPX: fix permission bogosity in create_proc_entry usage
<acme@conectiva.com.br>
o LLC: fix permission bogosity in create_proc_entry usage
<jdike@uml.karaya.com>
Added a missing directory to the arch/um/kernel Makefile.
<acme@conectiva.com.br>
o Appletalk: convert aarp_lock from spinlock to rwlock
- CodingStyle cleanups
- make aarp_cleanup_module always present, as needed by DDP.
<rddunlap@osdl.org>
[PATCH] build cpia video driver
This patch enables the cpia driver to build on 2.5.41.
<vojtech@suse.cz>
Change PC-keyboard mappings to follow MS Keyboards - a de facto
standard for extended keys.
<vojtech@suse.cz>
Initialize struct input_dev in input drivers before it's passed to input_event().
input_register_device() usually does that, but some drivers will call
input_event() before registering to pre-load the absolute values in
struct input_dev in an easy way.
<vojtech@suse.cz>
Add german keyboard \ to the default table of atkbd.c
<vojtech@suse.cz>
Make i8042.c even less picky about detecting an AUX port because of
broken chipsets that don't support the LOOP command or report failure
on the TEST command. Hopefully this won't screw any old 386/486
systems without the AUX port.

This has been in -dj for eons, and has had no ill effect.
<davej@codemonkey.org.uk>
[PATCH] numerous __FUNCTION__ pasting fixes
<davej@codemonkey.org.uk>
[PATCH] unify slab namespace.
Other slabs have '_' to separate words instead of ' '.
Same patch went into 2.4
<davej@codemonkey.org.uk>
[PATCH] Don't prefetch io space.
memcpy_to/fromio shouldn't be using memcpy,
as this could equate to the versions that

Since we now always have $(TOPDIR) = `pwd`, some usages of $(TOPDIR)
can go away.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Buglet in Documentation/DocBook/Makefile
'make mrproper' incorrectly deletes *~-style editor backup files
from the top-level directory. This bug was introduced in 2.5.29
when the top-level Makefile was changed to remain in the top-level
directory when invoking DocBook's Makefile:

The reasoning behind this is a space saving of
8KB per CPU.

[PATCH] compile fixes
cpqarray uses disk_alloc instead of alloc_disk. Same typo is in cciss,
rd.c sets ->first_minor to 0 for all units and HD_IRQ definition is
needed if CONFIG_BLK_DEV_HD is defined.

[PATCH] aacraid Makefile error in 2.5.41
I tried building the aacraid driver in 2.5.41 and got an error
saying that O_TARGET usage was obsolete. The following change
to the Makefile allows me to build.
<anton@samba.org>
[PATCH] one of these things is not like the others...
Or in this case two. This makes the migration and ksoftirq threads
match the naming convention of the workqueue threads.
Apply it and marvel at how neater a ps looks.
<mbligh@aracnet.com>
[PATCH] NUMA-Q fixes
This patch basically just renames usages of CONFIG_MULTIQUAD to
CONFIG_X86_NUMAQ. The original multiquad option covered a variety
of sins, and just made a mess (my fault). After extensive community
discussion, this is the naming scheme everyone agreed to - the
CONFIG_X86_NUMAQ option already exists, we're just renaming usages
of MULTIQUAD to it, and removing the MULTIQUAD option.
Stuff that's really to do with clustered APIC mode is put under
CONFIG_CLUSTERED_APIC instead, as it's not specific to the NUMA-Q.
Note that the definitions of clustered_apic_mode are still duplicated,
so the changes appear twice. I'm not making it worse, just haven't
fixed this one yet, will do that next.
Patch was written by Matt Dobson.

[PATCH] fix READA in ll_rw_block()
- Don't convert READA into READ in ll_rw_block().
<akpm@digeo.com>
[PATCH] discontigmem compilation fix
A discontigmem compilation fix From Bill Irwin
<akpm@digeo.com>
[PATCH] discontigmem fixes and cleanups
From Martin Bligh
This patch fixes a nasty bug that wli found in buffer.c which
cause an oops - we were using contig_page_data on a discontigmem
machine. It's a slightly modified version of the fix wli suggested,
tested on NUMA-Q.
I've also added code to not define contig_page_data for discontigmem
systems, to stop this from happening again. I wrapped a couple of
bootmem functions that were using it in #ifndef CONFIG_DISCONTIGMEM.
I suppose it's possible (though unlikely) that some other discontig
arch might need to wrap a couple of functions in their tree similarly,
but any borkage will just give a simple clear compiler error telling
them exactly where the problem is.
<akpm@digeo.com>
[PATCH] node-local mem_map for ia32 discontigmem
From Martin Bligh.
This patch remaps the lmem_map (struct page) arrays for each node onto
their own nodes. This is non-trivial, since all of ZONE_NORMAL, and
hence permanently mapped KVA resides on node 0.
Very early in the boot sequence, it calculates the size of the lmem_map
arrays (rounding up to the nearest large page size), and reserves a
suitable amount of permanent KVA by shifting down max_low_pfn to create
a gap between max_low_pfn and highstart_pfn (both of which are normally
about 896Mb).
It then uses the new set_pmd_pfn function to set up the pmds correctly
so that the large pages point at the physical addresses reserved from
the remote nodes.
Tested on NUMA-Q and some ratty old i386 PC kicking around under my
desk (on 2.5.36-mm1). Was good for a 20% improvement in system time on
kernel compile when I initially benchmarked it against 2.5.32 or
something - due to a reduction in inter-node traffic, better
interconnect cache usage and locality. Should have no effect on any
system other than i386 NUMA systems.
<akpm@digeo.com>
[PATCH] remove get_free_page()
This used to be a macro wrapper around get_zeroed_page().
It was a dreadful choice of name, because it hid the fact that this
function memsets the page. Probably, lots of the callers didn't
actually want to do that but this patch does not make such
optimisations.
At least now, people may spot a `get_zeroed_page' in there and realise
that the page doesn't actually need to be initialised.
The patch also changes get_zeroed_page() to go BUG if called with
__GFP_HIGHMEM. It returns the address of the page's memory and hence
can only be used for direct-mapped pages (wli).
<akpm@digeo.com>
[PATCH] numa: alloc_pages_node cleanup
Patch from Christoph Hellwig
It turns alloc_pages_node into a static inline, in the same fashion as
alloc_pages. There is no need for #ifdef CONFIG_NUMA in the patch, as
the numa node identification functions are sensible enough to do the
right thing for non-NUMA systems. Moves alloc_pages_node from numa.c
to gfp.h, and removes the EXPORT_SYMBOL which is no longer needed as
this is now an inline.
<akpm@digeo.com>
[PATCH] free_area_init cleanup
From Christoph Hellwig.
If we always pass &contig_page_data into free_area_init_node for the
non-distcontig case we can merge both versions of that function into
one. Move that one to page_alloc.c and thus kill numa.c which was
totally misnamed, btw.
<akpm@digeo.com>
[PATCH] move library functions from ramfs into libfs
From Bill Irwin
The simple_link(), simple_unlink(), simple_rename(),
simple_sync_file(), simple_rmdir(), and simple_empty() functions are
easy to duplicate. Basically, I duplicated them in an fs patch of
mine, and Linus told me to put them in libfs.c
Pat Mochel has acked the changes for driverfs (in that he'll convert
the stuff over when they're available from libfs), and my hugetlbfs
implementation was the thing that spurred the whole incident.

[PATCH] make bio->bi_max contain max vec entries
This changes the way we do pool lookups when freeing a bio. Right now
we use bi_max as a handle into bvec_array[], to find the pool where it
came from. This used to be just fine, because if you had a private bio,
you could specify your own destructor. But now we have bio_add_page()
which also needs to know where the bio came from, or more precisely, it
needs to know how many entries the bio can hold.
So I've changed bi_max to bi_max_vecs, it now contains the number of vec
entries in the bio. Privately allocated bio's (or on stack) can now just
set bio->bi_max_vecs to reflect the max size. The pool index for the
default destructor is stored in the top bits of bi_flags.

[PATCH] Base set of LSM hooks for SysV IPC
The patch below adds the base set of LSM hooks for System V IPC to the
2.5.41 kernel. These hooks permit a security module to label
semaphore sets, message queues, and shared memory segments and to
perform security checks on these objects that parallel the existing
IPC access checks. Additional LSM hooks for labeling and controlling
individual messages sent on a single message queue and for providing
fine-grained distinctions among IPC operations will be submitted
separately after this base set of LSM IPC hooks has been accepted.

[PATCH] cpqarray SMP deadlock fix
This fixes some critical bugs in cpqarray in 2.5. One of the fixes
essentially backs out the block queue stop/start behavior that was added
recently. This code as it stands is buggy and locks up under even light
SMP workloads. Certainly we want the performance benefits of proper
block queue plugging, but the driver needs some work before it will fit
nicely.
Some of these fixes do theoretically hurt performance, but when you
consider that the driver is unusable under SMP as-is, I think it is
right to get correctness first.
Specifically, this patch does the following:
* Adds locking to proc queue-walking code for debugging use. Note that
the proc registration is still broken and I've left it that way since
this stuff should probably migrate to driverfs anyway.
* Moves interrupt enabling so queue lock is initialized before
interrupts are enabled. Otherwise if we get a quick interrupt we oops
the machine.
* Removes unconditional IRQ enabling in do_ida_request(). The block
layer takes the spinlock with irq_save so if we're going to play this
trick then we need to irq_restore. For now, just eliminate the
unlocked region.
* Remove block queue stop/start logic since it can leave the queue
stopped with no outstanding completions to start it again. Plugging
logic can come back but it should go hand-in-hand with a cleanup of
the driver's request handling algorithm. If nobody screams about this
patch I'll go ahead and start making those improvments.

[SERIAL] Remove old pci_board cruft from serialP.h
<mochel@osdl.org>
driver model: and present field to struct device and implement device_unregister().
device_unregister() is intended to be the complement of device_register(), and assumes
most of the functionality of the current put_device(). It should be called by the bus
driver when a device is physically removed from the system.
It should _not_ be called from a driver's remove() method, as that remove() method is called
via device_detach() in device_unregister().
dev->present is used to flag the physical presence of the device. It is set when the device
is registered, and cleared when unregistered. get_device() checks this flag, and returns
a NULL pointer if cleared. This prevents anyone from obtaining a reference to a device
that has been unregistered (removed), but not yet been freed (e.g. if someone else is
holding a reference to it).
put_device() BUG()s if dev->present is set. A device should be unregistered before it is
freed. This will catch people doing it in the wrong order.

[PATCH] IDE: only register devices that are present
<akpm@digeo.com>
[PATCH] 64-bit sector_t - various driver changes
peter's code works for me, and the 40-odd people who download
the -mm patches. Anton has tested it on ppc64 and I presume that
Peter has tested it on ia64. I use gcc-2.91.66 and others use
later compilers. I expect that any remaining problems will
mainly be caught by the compiler. And compiler bugs can be
detected by turning off the option in config and seeing if things
get better.
From Peter Chubb
- do_request() function takes sector_t not unsigned long as the
block number to operate on.
- Various casts to long where the underlying device can never get
big enough to warrant a 64-bit sector offset.
- Cast sector_t to unsigned long long when printing.
<akpm@digeo.com>
[PATCH] 64-bit sector_t - printk changes and sector_t cleanup
From Peter Chubb
printk changes: A sector_t can be either 64 or 32 bits, so cast it to a
printable type that is at least as large as 64-bits on all platforms
(i.e., cast to unsigned long long and use a %llu format)
Transition to 64-bit sector_t: fix isofs_get_blocks by converting the
(possibly 64-bit) arg to a long.
SCSI 64-bit sector_t cleanup: capacity now stored as sector_t; make
sure that the READ_CAPACITY command doesn't sign-extend its returned
value; avoid 64-bit division when printing size in MB.
Still to do:
- 16-byte SCSI commands
- Individual scsi drivers.
<akpm@digeo.com>
[PATCH] 64-bit sector_t - driver changes
From Peter Chubb
Compaq Smart array sector_t cleanup: prepare for possible 64-bit sector_t
Clean up loop device to allow huge backing files.
MD transition to 64-bit sector_t.
- Hold sizes and offsets as sector_t not int;
- use 64-bit arithmetic if necessary to map block-in-raid to zone
and block-in-zone
<akpm@digeo.com>
[PATCH] 64-bit sector_t - filesystems
From Peter Chubb
Filesystem migration to possibly 64-bit sector_t:
- bmap() now takes and returns a sector_t to allow filesystems
(e.g., JFS, XFS) that are 64-bit clean to deal with large files
- buffer handling now 64-bit clean
Enable 64-bit sector_t on IA32 and PPC.
kiobufs takes sector_t array, not array of long.
Fix blkmtd.c to deal in such an array.
Miscellaneous fixes for 64-bit sector_t.
- missed printk formats
- ide_floppy_do_request had incorrect signature
- in blkmtd.c there was a pointer used to
manipulate an array to be used by kiobuf --
it was unsigned long, needed to be sector_t
<akpm@digeo.com>
[PATCH] 64-bit sector_t - md fixes
From Peter Chubb
(Yes I forgot something... Without this patch, trying to use RAID
without CONFIG_LBD would fail.)
Fix md operation without CONFIG_LBD --- don't try to include __udivdi3
etc.
<akpm@digeo.com>
[PATCH] 64-bit sector_t - remove udivdi3, use sector_div()
From Peter Chubb
Get rid of need for GCC _udivdi3 and _umoddi3 helper functions
- use sector_div more aggressively.
<akpm@digeo.com>
[PATCH] Fix xxx_get_biosgeometry --- avoid useless 64-bit division.
From Peter Chubb
The bios geometry is almost useless, except for fdisk to try to write
an MSDOS partition table that is vaguely compatible with one written by
other operating systems.
If the size of disc will overflow a ten-bit cylinder number, then all
bets are off anyway. So fake it by casting the true disc capacity to a
smaller type (than u64), so that we avoid 64-bit division on 32-bit
platforms. If the disc is small enough that the number of cylinders is
correct, then this has no effect; otherwise, the number-of-cylinders we
report is bogus, but you can't use an MSDOS-format partition table on
such a drive anyway --- use the EFI GPT or the LDM partitioning, which
use 64-bit offsets internally.
<akpm@digeo.com>
[PATCH] Hardwire CONFIG_LBD to "on" for testing

[PATCH] missing exports
the netfilter ipt owner module still needs the following to compile
<mochel@osdl.org>
IDE: register ide driver for all ide drives; not just for disk drives.
This adds
struct device_driver gen_driver;
to ide_driver_t, which is filled in with necessary fields when an ide
driver calls ide_register_driver(). That then registers the driver with
the driver model core.
As a result, this gives us the following output in driverfs:
# tree -d /sys/bus/ide/drivers/
/sys/bus/ide/drivers/
|-- ide-cdrom
`-- ide-disk
The suspend/resume callbacks in ide-disk.c have been temporarily
disabled until the ide core implements generic methods which forward
the calls to the drive drivers.
<mochel@osdl.org>
IDE: Add generic remove() method for drives; remove reboot notifier.
The remove() method is generic for all drives, and set in ide_driver_t::gen_driver.
The call simply forwards the call to ide_driver_t::standby().
This obviates the need for IDE reboot notifier. The core iterates over all present
devices in device_shutdown() and unregisters each one.
<mochel@osdl.org>
IDE: make ide_drive_remove() call driver's ->cleanup().
This was accidentally dropped before, but re-added now to completely mimic
behavior of the reboot notifier IDE used to have.

<rml@tech9.net>
[PATCH] fix preempt_count overflow with brlocks
Now that brlocks loop over NR_CPUS, on SMP every br_lock/br_unlock
results in the acquire/release of 32 locks. This incs/decs the
preempt_count by 32.
Since we only have 7 bits now for actually storing the lock depth, we
cannot nest but 3 locks deep. I doubt we ever acquire three brlocks
concurrently, but it is still a concern.
Attached patch disables/enables preemption explicitly once and only
once for each lock/unlock. This is also an optimization as it
removes 31 incs, decs, and conditionals. :)
Problem reported by Andrew Morton.

[PATCH] ips driver 3/6
This patch adds an Adaptec copyright, makes a few
minor comment changes, and removes a few unneeded
macros.
<David_Jeffery@adaptec.com>
[PATCH] ips driver 4/6
This is by far the biggest patch. It is a rewrite of the
driver's horrid locking. In addition to the host_lock,
the driver used to have 4 other locks per adapter!
It had a redundant ha_lock and a lock for each of 3
queues. In a few places it also played with atomic bit
setting. And almost all of it was useless as the
host_lock was already held.
This patch cleans up this locking nightmare. The driver
now uses the host_lock exclusively. Only a few places
needed to add calls to lock the host_lock. Most of
this patch is deletion of useless extra locking.
<David_Jeffery@adaptec.com>
[PATCH] ips driver 5/6
2 minor bug fixes.
The first section makes sure we limit the size of the
sense_buffer copy to the target buffer's size so that
we don't overflow the sence_buffer.
The other sections remove some pointer arithmatic that
is wrong on 64bit machines do to padding. Instead, just
call the pci_map functions on the buffer.

[PATCH] ips driver 6/6
2 bug fixes for scsi pass through
When talking directly to scsi devices, the driver would
sometimes get two things wrong. We could set too short

non-zero values in certain fields which we shouldn't have
been using. This patch corrects these problems.

[PATCH] move_one_page atomicity fix
The atomicicty fix for move_one_page() was not quite right.
We only do the page_table_present() test if CONFIG_HIGHPTE=y. Which is
fine, but even with CONFIG_HIGHPTE=n, the pte mapping functions still
do an inc_preempt_count() due to their unconditional kmap_atomic(). So
we get a might_sleep() warning.
The warning is actually bogus, because those pte's are always in
direct-mapped memory.
So hm. Three fixes suggest themselves:
1: Run the page_table_present() test if CONFIG_HIGHMEM.
Rejected: penalises non-pte_highmem setups
2: Make kmap_atomic() not do inc_preempt_count() is the page was
direct mapped.
Rejected: I don't think we want kmap_atomic side effects to be
varying according to the page which was passed.
3: Change the pte mapping functions so they don't run kmap_atomic at
all if CONFIG_HIGHPTE=n
This is what I did. And guess what? For CONFIG_HIGHMEM=y,
CONFIG_HIGHPTE=n this patch shrinks the kernel by 5 kbytes. Because
kmap_atomic is inlined.
The lesson: we do way too much damn inlining.

[PATCH] fix the raw driver
Fix the raw driver by tricking it into performing O_DIRECT IO against
the bound blockdev.
- rewrite the i_mapping for /dev/raw/raw0 to point at the same thing
as bdev->bd_inode->i_mapping. We've performed a bdget() against the
blockdev, which should pin it for the correct lifetime.
- set the O_DIRECT bit on the caller's file->flags.

[PATCH] remove radix_tree_reserve()
From Hugh Dickins.
radix_tree_reserve() exists solely for the tmpfs move_to_swap_cache()
and move_from_swap_cache() functions, and yet they don't need it: there
is no problem in the one page being simultaneously listed in two radix
trees (while both locks are held). Use radix_tree_insert(), and remove
radix_tree_reserve(); also removed a few blank lines.

[PATCH] remove the sched_yield from the ext3 fsync path
The changed sched_yield() semantics have made ext3's transaction
batching terribly slow.
Apparently a schedule() fixes that, although it probably breaks
transaction batching.
This patch largely fixes my complaints about the new scheduler being
extremely sluggish to interactive applications. Evidently those
applications were calling fsync() and were spending extremely long
periods in sched_yield().

[PATCH] make readv/writev return 0 for 0 segments
Should resolve an ongoing fiasco concerning what we should return to
userspace if they do a readv or writev of zero segments.
SuS is ambiguous, but implies EINVAL. We're currently returning
EINVAL, but 2.4 returns zero.
I think zero makes more sense, and it is what 2.4 does.

[PATCH] linux-2.5.41_timer-changes_A4 (1/3 - infrastructure)
The i386 time.c code is turning into a mess. We've got multiple
functions that do the same thing, only with different hardware, all
surrounded #ifdefs and even more difficult to follow #ifndefs. George
Anzinger is introducing a new ACPIpm time source, I'm going to attempt
to add the cyclone counter as a time source, and in the future there
will be HPET to deal with. These will not go in cleanly together as
things are now.
Inspired by suggestions from Alan, this collection of patches
tries to clean up time.c by breaking out the PIT and TSC specific parts
into their own files. Additionally the patch creates an abstract
interface to use these existing time soruces, as well as make it easier
to add future time sources.
It introduces "struct timer_ops" which gives the time code a
clear interface to use these different time sources. It also allows for
clearer conditional compilation of these various time sources.
This first patch (part 1 of 3) provides the infrastructure
needed via the timer_ops structure, as well as the select_timer()
function for choosing the best available timer.
<johnstul@us.ibm.com>
[PATCH] linux-2.5.41_timer-changes_A4 (2/3 - bulk move)
This is part 2 of 3 of my timer-change patch. Part 2 is just a
bulk move of code out of time.c and into timer_pit.c and timer_tsc.c. No
code is changed, only moved.
Please note, this code will not compile without the final third
part of this patch collection. This was done for readability alone.
<johnstul@us.ibm.com>
[PATCH] linux-2.5.41_timer-changes_A4 (3/3 - integration)

[PATCH] linux-2.5.41_cyclone-timer_B2
In order to demonstrate how new time-sources are added to my
timer-changes patch. Here is my current version of my cyclone-timer
patch for 2.5.41. This uses the infrastructure set up in the
timer-changes_A4 patch set to add the cyclone counter (found on IBM
Summit Based hardware) as a time-source.
The current code is not enabled as it also depends on James
Cleverdon's 2.5 summit patch, however it illustrates how cleanly new
time-sources can be added.

[PATCH] isofs fix
The patch below removes some dead code and nonsense code.
The part that changes behaviour is
- if (sbi->s_cruft == 'n' &&
- (volume_seq_no != 0) && (volume_seq_no != 1)) {
- printk(KERN_WARNING "Warning: defective CD-ROM "
- "(volume sequence number %d). "
- "Enabling \"cruft\" mount option.\n", volume_seq_no);
- sbi->s_cruft = 'y';
- }
that has already bitten lots of people.
Nothing is wrong with a volume sequence number different from 0 or 1.

[PATCH] A basic NFSv4 client for 2.5.x
Instantiate a new file, include/linux/nfs4.h, which contains

[PATCH] A basic NFSv4 client for 2.5.x
This patch changes the interface of the ->readdir() nfs_rpc_op
so that its first argument is a dentry instead of an inode.
[Explanation: The dentry is required because in NFSv4, we need
to make use of the _parent_ directory's inode. This is because
NFSv4 servers no longer return an entry for ".." in the READDIR
response, so the client kernel needs to fake this entry, inode
number and all.]
<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
This patch changes the interface of the ->setattr() nfs_rpc_op
so that its first argument is a dentry instead of an inode.
[Explanation: The dentry is required because in NFSv4, we may
need to OPEN the file before doing the SETATTR. (This is
required if the file size is changed as part of the setattr.)
Opening the file requires making use of the containing
directory's inode.]
<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
In NFSv4, there is no hard limit on the length of symlink text.
This patch changes the -ENAMETOOLONG test in nfs_symlink() accordingly.
<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
In NFSv4, an fsid is a 64-bit major number together with a 64-bit
minor number. In previous versions, an fsid is a single number.
This patch changes 'struct nfs_fattr' accordingly.
<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
This is a nontrivial change to the NFS client.
NFSv4 defines a new file attribute, change_attr. This is a per-file
opaque quantity returned by the server, whose value is required to
change whenever the file is modified. If it exists, we want to use
it for all cache consistency checks in nfs_refresh_inode(). Some
operations also return a "pre-operation" value of the change_attr;
we want to take this into account too.
First, define flags
NFS_ATTR_FATTR_V4 - indicates that the 'struct nfs_fattr' is an
NFSv4 fattr, so the change_attr field is valid
NFS_ATTR_PRE_CHANGE - indicates that the server returned a pre-operation
change_attr, so the pre_change_attr field is valid
Second, change nfs_refresh_inode() so that the caches are invalidated
if there is a change_attr mismatch. Exception: If the pre_change_attr
tells us that the mismatch was caused by our operation, then do not
invalidate the caches.
This patch should leave the logic in nfs_refresh_inode() unchanged
if neither of the new flags are set.
<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
If the NFS_ATTR_FATTR_V4 flag is set, use the NFSv3 convention for
the 'space_used' part of the fattr.
<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
This is a nontrivial change to the NFS client.
Synchronous READ operations are currently done via the ->read() nfs_rpc_op.
Therefore, the synchronous READ path can easily be adapted for NFSv4. On
the other hand, the asynchronous READ path contains several NFSv3-specific
features, which make it difficult to adapt for NFSv4.
In this patch and the next, we modify the async READ path to be
version-agnostic. This patch just changes the 'struct nfs_read_data'
so that the v2- and v3-specific parts are moved into a private area,
with room for a v4-specific part in parallel. None of the logic is
changed.
<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
This is a nontrivial change to the NFS client.
In this patch, we finish modifying the async READ path so that it is
version-agnostic. We define a new nfs_rpc_op ->setup_read(), and move
the v2- and v3-specific code in nfs_read_rpcsetup() there. We also
have to change nfs_readpage() result so that the 'count' of bytes
read is a parameter. The extra parameter means that it can no longer
be ->tk_exit(). Instead, it is called from a version-specific ->tk_exit()
routine which is set in ->read_setup().
The upshot of all this is that the version-specific part of the
async READ path has been encapsulated in a new nfs_rpc_op
->read_setup(), and NFSv4 can share the logic for asynchronous
READ's with NFSv2 and v3.
<trond.myklebust@fys.uio.no>
[PATCH] Fix NFS locking over TCP
The 2.5.x RPC code is currently broken in that it demands that all
tasks that call xprt_create_proto() in order to open a TCP socket must
have CAP_NET_BIND_SERVICE capabilities, and must bind to a privileged
port.
This breaks the NLM locking code and its use of the call_bind() RPC
portmapper lookup feature.
This patch allows the built-in portmapper client to use unbound TCP
sockets if the user does not have the necessary capabilities.

- adds better documentation to the timer function structure
- makes the timer init function return 0 on success
- NULL terminates the list of timers to make further patches

<Andries.Brouwer@cwi.nl>
Since 2.5.32 the keyboard repeat code was broken.
The reason Vojtech broke it was the stupid name of a field
in struct kbd_repeat, namely "rate". Every sane person
expects that a rate has dimension [1/sec], but here the
"rate" is a time period measured in msec.
So, the patch below first of all fixes the code,
and secondly changes the name.
Since Vojtech used PERIOD as index, I also used period
as field name in the struct.
Half of the stuff below is actually from Alan Stern.

commands, it will make the mid layer think more commands have been
allocated.

<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
In NFSv3, an RPC is retried if the special error NFSERR_JUKEBOX is
received. This generic bit of postprocessing happens invisibly for
synchronous RPC's, but in the async case, the ->tk_exit callback
must call nfs_async_handle_jukebox() by hand.
In NFSv4, we also need generic postprocessing of async RPC's, but
the details are different. Therefore, we don't want to call
nfs_async_handle_jukebox(); we want to call a different, NFSv4-specific
routine. Therefore, we want to move calls to nfs_async_handle_jukebox()
out of the "generic" NFS code and into NFSv3-specific routines. This
has already been done for async READ and WRITE in the preceding patches,
but there is still one outstanding case: the async REMOVE in sillyrename.
This patch removes nfs_async_handle_jukebox() from the async sillyrename
path, and puts in the NFSv3 ->unlink_done() rpc_op.
<trond.myklebust@fys.uio.no>
[PATCH] A basic NFSv4 client for 2.5.x
Now that all calls to nfs_async_handle_jukebox() have been moved to

consistent with the naming conventions of that file.

NFS4_SVC_XDRSIZE if v4 is defined
else NFS3_SVC_XDRSIZE if v3 is defined
else NFS2_SVC_XDRSIZE (formerly NFSSVC_XDRSIZE)
This always works, since
NFS4_SVC_XDRSIZE >= NFS3_SVC_XDRSIZE >= NFS2_SVC_XDRSIZE.
The value of NFSD_BUFSIZE has also been moved to const.h, since we need
the definition available in nfs4proc.c

[PATCH] kNFSd: Stub support for name lookup
NFSv4 need to be able to make from user/group name
to user/group id. This include file contains some
simple stubs to do this. They will be replaced with
something that really works later.

[PATCH] kNFSd: Giant patch importing NFSv4 server functionality
Now that all the hooks are in place, this large patch imports all
of the new code for the NFSv4 server.
This patch makes almost no changes to the existing nfsd codebase
(these have been taken care of by the preceding patches).
One aspect of the NFSv4 code deserves comment. The most natural scheme
for processing a COMPOUND request would seem to be:
1a. XDR decode phase, decode args of all operations
2a. processing phase, process all operations
3a. XDR encode phase, encode results of all operations
However, we use a scheme which works as follows:
1b. XDR decode phase, decode args of all operations
2b. For each operation,
process the operation
encode the result
To see what is wrong with the first scheme, consider a COMPOUND
of the form READ REMOVE. Since the last bit of processing for
the READ request occurs in XDR encode, we might discover in step
3a that the READ request should return an error. Therefore, the
REMOVE request should not be processed at all. This is a fatal
problem, since the REMOVE was already been done in step 2a!
Another type of problem would occur in a COMPOUND of the form
READ WRITE. Assume that both operations succeed. Under scheme
(a), the WRITE is actually performed _before_ the READ (since
the "real" READ is really done during XDR encode). This is
certainly incorrect if the READ and WRITE ranges overlap.
These examples might seem a little artificial, but nevertheless
it does seem that in order to process a COMPOUND correctly in
all cases, we need to use scheme (b) instead of scheme (a).
(To construct less artificial examples, just substitute GETATTR
for READ in the examples above. This works because the "real"
GETATTR is done during XDR encode: one would really have to
bend over backwards in order to arrange things otherwise.)

[PATCH] kNFSd: Tidy up the rpc authentication interface.
Define auth_ops that contains a method for authenticating a request and a
method for authorising a reply. Call both methods as appropriate.
Also discard rq_verfed and cr_flavour, neither ever used.
And discard rq_auth as it isn't needed.

[PATCH] kNFSd: Initialial caching infrastructure for RPC authentication caches
This patch provides a "virtual class" for defining caches
that make user-space information available in the kernel
It is intended for RPC services or clients that need user-space
support for authentication.
As yet, support for userspace interaction isn't included as I want
that to be able to have separate review.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Use new cache infrastructure for auth_unix specific lookups.
This patch introduces two caches using the new infrastucture, and the
concept of a 'domain'.
A 'domain' refers to a collection of clients that all have the same
view of the nfs server, and all have the same access rights (modulo
different users on the clients). For AUTH_UNIX (and AUTH_NULL), the
domain is determined from the IP address. For other authentication
styles, the domain might be determined directly from the credentials.
Each auth flavour knows how to allocate and free it's domain-specific
infomation.
auth_domain_cache maps a name to a domain which is owned by
an auth flavour.
ip_map_cache is a cache specific to AUTH_UNIX which maps
IP address to domain.
With this patch, svcauth_unix.c is created to store all
auth_unix related code.
The IP address lookup code is removed from nfsd/exports.c
sunrpc module initilisation is moved out of stats.c into sunrpc_syms
which seemed to be the most central .c file. It now registers these
two caches.
Now that the caches are being used, nfsd needs to call cache_clean
periodically.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Move auth domain lookup into svcauth
Instead of doing the lookup from ipaddr to domain inside
the nfs server, (and also when lockd calls into nfsd) it is
now done at the rpc authentication level which is a more
sensible place for it.
Note that both AUTH_UNIX and AUTH_NULL do the same lookup.
So that the rpc layer knows that nfsd and lockd both uses the
name space of domains (while other hypothetical services may
not) we introduce a 'class' for each service which svc_auth combines
with the IP address when doing a lookup.

[PATCH] kNFSd: exp_getclient, now just a small wrapper, goes in favour of auth_unix_lookup
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Open code exp_get and exp_get_fsid in the one place they are called.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Convert export-table to use new cache code
This introduces two caches, svc_export_cache (nfsd.exports) and
svc_expkey_cache (nfsd.fh).
nfsd.exports maps client+directory -> export options.
nfsd.fh maps client + filehandle-fragment -> directory.
A major part of this change is that export entries are now reference counted,
so we have to be careful to keep those counts correct.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Don't over-write rpc request with response.
We are going to want rpc request to be immutable so that
we can take a copy and put it aside to be processed later.
Currently the tcp code writes the response into the same
buffer as the request, thus corrupting the request.
With this patch, the response goes after the request. There should
always be enough room as large reqeusts (Write) has small
responses, and large responses (read) are for small requests.
buflen is changed for requests to record the length of the
request. It already gets reset for each new request.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: decode symlink inplace to avoid modifying request
Rather than possibly modifying a request (as
xdr_decode_string can) we use xdr_decode_string_inplace
to symlink contents. This string may not be nul terminated
(though it often is) so in the 'unlikely' event that is isn't
nul terminated, we copy it into a kmalloced space first.
It might be nice if vfs_symlink took a length, but then every
filesystem would have to as well....
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Provide support for request deferral and revisit.
cache.c gets code to allow a 'request' to be referred pending
an update of a cache item, and revisited when the item is
updates.
svcsock.c gets code to store the relevant part of a request on deferral, and
to re-queue it when the cache item that caused the deferral is
filled in.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Create files: /proc/net/rpc/$CACHENAME/channel for communicating cache updates with kernel
Each cache gets it's own 'channel' at
/proc/net/rpc/$CACHENAME/channel
Reads from the file will return all pending requests, one at a time.
select will block when at end of file.
writes will pass full lines in to be processed.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Provide generic code for making an upcall.
This code enhances 'cache_check' to try to initiate
an up-call if the cache entry is not up-to-date, and also
defines add_word and add_hex for formating up-call
requests. See rpc-cache.txt for more detail.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Implement ip_map_request for upcalls
This is the first upcall to actually be coded.
A request will look like:
nfsd 127.0.0.1
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Implement get_word to help in parsing cache updates
get_word understands both \x and \012 quoting styles.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: get_int and get_expiry to help in parsing.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Impletement ip_map_parse to allow filling auth.unix.ip cache
a message should be:
nfsd 10.0.1.1 {Expirydate} domainname
if domainname is empty, then this is a NEGATIVE entry: that
IP address will be deined access.
{Expirydate} is seconds since unix epoch.
e.g. 1036105199 for midnight, halloween.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: upcall/update for export tables
Add _request and _parse methods for nfsd.fh and
nfsd.exports tables.
nfsd.fh maps a filehandle-fragment to a path for a client,
and nfsd.exports maps a path to export options for a client.

[PATCH] fix crash in yenta_bh() on card insertion/removal
In the current kernels, when a PCMCIA card is inserted into or
removed from a socket, the kernel oopses because yenta_bh() tries to
dereference a NULL pointer.
The attached patch initialises the argument to yenta_bh() so that this
doesn't happen.

[PATCH] Coda FS update
Most of these changes have been tested and used in the 2.4 tree, so this
is mostly a forward port of 2.4 bugfixes.
* C99 initializers
* Added specific initializations instead of assuming that the private
part of the inode is already initialized.
* Remove unused code.
* Moved container file to the struct file private data, this is to
* correct the session semantics model when file updates are fetched from
* the server (old 'sessions' shouldn't see the new container yet).
* Fixed consistency (and occasional oopes) when mmap-ing Coda files.
* Fixing up inode numbers in readdir, old libc5 getcwd was broken.
* Nuked upcall_stats, all of this can easily be maintained in userspace,
and the existing code suffers from overflows in the fixed point
calculations.

[PATCH] Efficient bswab64 for i386
Due to some bugs in byteorder/generic.h linux would always use C handcoded
swab64 for 64bit ntohq or cpu_to_be64. The C version is very inefficient
and expands to 30+ instructions of horrible code.
This hurts on filesystems that use on disk big endian data structures
with 64bit data types.
This patch adds an assembly optimized swab64 to fix it. Now bswab64 is
4 instructions when your CPU supports bswap and 9 when it doesn't.
Tests were done with gcc 3.2, may be different on older gcc.
This is good for ~600 bytes code size reduction in XFS (gcc 3.2):
Before:
503199 3296 1682 508177 7c111 fs/xfs/xfs.o
After:
502543 3296 1682 507521 7be81 fs/xfs/xfs.o
Also should be faster.
Also some minor cleanups in the file.
