Summary of changes from v2.5.66 to v2.5.67
============================================
<agrover@groveronline.com>
ACPI: Re-enable build w/o CONFIG_PCI (Pavel Machek)
<ink@jurassic.park.msu.ru>
[PATCH] alpha: err_titan.c compile fix
Fix unused variables when CONFIG_VERBOSE_MCHECK is not set.
Ivan.
<sfr@canb.auug.org.au>
[PATCH] compat_sys_fcntl{,64} 9/9 Aalpha part
This is only partly to do with the other parts of this patch set. All it
does is remove struct flock64 from the Alpha port.
diff -ruN 2.5.64-2003030918-32bit.1/include/asm-alpha/fcntl.h 2.5.64-2003030918-32bit.2/include/asm-alpha/fcntl.h
<agrover@groveronline.com>
ACPI: Fix GPE 1 handling (Takayoshi Kochi)
<blaschke@blaschke3.austin.ibm.com>
Code cleanup suggested by static analysis tool.
<akpm@digeo.com>
ppc64: support for Ingo's "fileoffset in pte" patch
<sam@ravnborg.org>
ppc64: makefile updates
<rmk@flint.arm.linux.org.uk>
[PCMCIA] pcmcia-2: Remove get_io_map and get_mem_map socket methods.
get_io_map and get_mem_map PCMCIA socket methods are never called
by the PCMCIA core code. They are therefore dead code, and can be
removed.
<rmk@flint.arm.linux.org.uk>
[PCMCIA] pcmcia-3: Remove bus_ops abstractions.
Remove bus_* abstractions from PCMCIA core and PCMCIA drivers; they
are unused.
<rmk@flint.arm.linux.org.uk>
[PCMCIA] pcmcia-4: introduce SOCKET_CARDBUS_CONFIG
Cardbus uses socket->cb_config to detect when the cardbus card has
been initialised. Since cb_config will eventually die, we need a
solution - introduce the SOCKET_CARDBUS_CONFIG flag, which is set
once we have initialised the cardbus socket.
<akpm@digeo.com>
ppc64: add PTE_FILE_MAX_BITS
<rmk@flint.arm.linux.org.uk>
[PCMCIA] pcmcia-5: Add locking to resource manager.
Add an element of locking to the resource manager - don't allow
the PCMCIA resource lists to be changed while the pcmcia code is
scanning them.
<rmk@flint.arm.linux.org.uk>
[PCMCIA] pcmcia-6: s/CONFIG_ISA/CONFIG_PCMCIA_PROBE/
Remove the dependence of the PCMCIA layer on CONFIG_ISA - introduce
CONFIG_PCMCIA_PROBE to determine whether we need the resource
handling code. This prevents oopsen on SA11x0 and similar platforms
which use statically mapped, non-windowed sockets.
<jgrimm@touki.austin.ibm.com>
[SCTP] Bundle SACK with outgoing DATA.
If we are sending DATA, bundle a SACK. Otherwise, we end up
always waiting for the delayed SACK rules (timer or every other
packet rule) to kick in.
<agrover@groveronline.com>
ACPI: Fix off by 1 error in C2/3 detection (Ducrot Bruno)
<paulus@samba.org>
ppc64: make sys_clone handle the CLONE_SETTLS flag
<agrover@groveronline.com>
ACPI: Interpreter update to 20030321
- Walking a list in the ISR is now required, so add a spinlock
- Add core support for GPE Block devices
- Change GPE interface accordingly
<vandrove@vc.cvut.cz>
[PATCH] Fix kobject_get oopses triggered by i2c in 2.5.65-bk
i2c initialization must not use module_init now, when it was converted
to the kobject interface. There are dozens of users which need it working
much sooner. i2c is subsystem after all, isn't it?
Fixes kernel oopses in kobject_get during system init which were happening
to me.
<greg@kroah.com>
i2c: remove i2c_adapter->name and use dev->name instead.
<david-b@pacbell.net>
[PATCH] usb_connect() kerneldoc
previous text was wrong/confusing, all it does
is pick a number. this routine should be merged
with usb_new_device() someday, but doing that
would mean changing the hcds (as well as hub.c)
so it's not worth it yet.
<david-b@pacbell.net>
[PATCH] usb hub diagnostics
More uniformity-in-diagnostics work, and don't emit
a error message in one known non-error case.
<david-b@pacbell.net>
[PATCH] usbtest catch -ENOMEM
Smatch seems to be returning mostly false positives,
but not this time.
<greg@kroah.com>
[PATCH] i2c: remove *data from i2c_adapter, as dev->data should be used instead.
<greg@kroah.com>
i2c: add struct device to i2c_client structure
Not quite ready to hook it up to the driver core yet.
<greg@kroah.com>
[PATCH] i2c: remove the data field from struct i2c_client
It's no longer needed, as the struct device should be used instead.
Created i2c_get_clientdata() and i2c_set_clientdata() to access the data.
<greg@kroah.com>
i2c: Removed the name variable from i2c_client as the dev one should be used instead.
<greg@kroah.com>
i2c: actually register the i2c client device with the driver core.
We have to initialize the client structure with 0 to keep the
driver core from oopsing.
Now everything is hooked up enough to start removing the i2c sysctl
and proc crud.
<greg@kroah.com>
[PATCH] i2c: fix up the chip driver names to play nice with sysfs
<greg@kroah.com>
i2c: ugh, clean up lindent mess in i2c-proc.c::i2c_detect()
Yes, this function now goes beyond 80 columns, but it's almost
readable, while the previous version was not.
Also removed some #ifdefs
<chris@wirex.com>
[PATCH] USB: potential dereference of user pointer errors in kobil_sct.c
<david-b@pacbell.net>
[PATCH] add missing usb_put_urb() after error
This is a multi-part message in MIME format.
<rmk@flint.arm.linux.org.uk>
[PCMCIA] pcmcia-7: Remove cb_enable() and cb_disable()
Remove support for the old PCMCIA cardbus clients - all cardbus
drivers should be converted to be full-class PCI citizens.
<greg@kroah.com>
i2c: fix up drivers/media/video/* due to previous i2c changes.
<greg@kroah.com>
i2c: fix up drivers/acorn/char/i2c.c due to previous i2c changes
I'm not going to touch the other driver in this directory, as it will
need more than just minor fixups to get correct.
<greg@kroah.com>
i2c: fix up drivers/ieee1394/pcilynx.c due to previous i2c changes.
<greg@kroah.com>
i2c: fix up drivers/video/matrox/i2c-matroxfb.c due to previous i2c changes
<rmk@flint.arm.linux.org.uk>
[PCMCIA] pcmcia-8/9: Clean up CIS setup.
- Re-order functions in cistpl.c.
- Combine setup_cis_mem and set_cis_map into one function.
- Move cis_readable(), checksum() and checksum_match() into rsrc_mgr.c
- Only pass the socket structure to validate_mem()
- Remove socket_info_t *vs variable, and the race condition along
with it.
- Pass the socket_info_t through validate_mem(), do_mem_probe() and
inv_probe() to these functions.
- Call cis_readable() and checksum_match() directly from
do_mem_probe().
<rmk@flint.arm.linux.org.uk>
[PCMCIA] pcmcia-10: Make cardbus use the new PCI functionality.
Now that we have the critical PCI changes in place, we can convert
cardbus to use this PCI functionality. This allows us to scan
behind PCI to PCI bridges on cardbus cards, and setup the bus
resources using the generic PCI support code.
Note that drivers/pci/setup-bus.c needs to be built when hotplug
(ie, cardbus) is enabled.
<yoshfuji@linux-ipv6.org>
[IPSEC]: Make get_acqseq() xfrm_state.c:xfrm_get_acqseq().
<hch@com.rmk.(none)>
[PCMCIA] drivers/pcmcia/Makefile tidyups
(1) use the builtin foo-$(BAR) mechanism of the 2.5 kbuild
(2) align all += foo.o statements
<paulus@samba.org>
PPC32: Add the definitions needed for nonlinear file mappings (pte_file etc.)
<agrover@groveronline.com>
ACPI: Disable NUMA support on x86-64 (Andi Kleen)
<agrover@groveronline.com>
ACPI: Fix compile issue (reported by Brendan Burns and Christian Neumair)
<greg@kroah.com>
[PATCH] i2c: fix typo that newer versions of gcc catch.
<shaggy@shaggy.austin.ibm.com>
JFS: Avoid deadlock when all tblocks are allocated
We need to save one tblock for forced transactions, and only transactions
changing the inode allocation tables should be forced.
<ambx1@neo.rr.com>
PnP Card Service Cleanups
Moves probing code to a central location and matches when new cards are
added instead of only when new drivers are added.
<ambx1@neo.rr.com>
PnPBIOS Update
- Prevents calling the node_info call more than necessary in order to take
load off the pnpbios
- intregrates the proc registration code with the device scanning code
- adds human readable error messages instead of number codes
- other small cleanups
<ambx1@neo.rr.com>
ALS100 Memory Leak Fix
This trivial patch adds a missing kfree, the leak occurs when
pnp_activate_dev fails.
<greg@kroah.com>
[PATCH] i2c: set up a "generic" i2c driver to prevent oopses when devices are registering.
This is needed as we are still not using the driver core model for
matching up devices to drivers, but doing it by hand. Once that is
changed, this will not be needed.
<anton@samba.org>
ppc64: Rework pci probe to be like alpha.
<paulus@samba.org>
ppc64: Add missing RELOCs
<hch@lst.de>
[NET]: Kill dev_init_buffers, was scheduled to die in 2.5.x
<toml@us.ibm.com>
[IPSEC]: Fix IPV6 UDP policy checking.
<anton@samba.org>
ppc64: fix pci probe on large bus systems
<anton@samba.org>
ppc64: Disable 32bit SLB invalidation optimisation for the moment
<anton@samba.org>
ppc64: Fix problem with casting out the segment for our kernel stack
<ink@jurassic.park.msu.ru>
[PATCH] alpha: file offset in pte
It's possible to squeeze more bits out of lower half of pte,
but 32 seem to be a plenty...
Ivan.
<ink@jurassic.park.msu.ru>
[PATCH] alpha: handle unaligned REFQUADs produced by BUG() macro
<ink@jurassic.park.msu.ru>
[PATCH] alpha: pci update
- Check for parent PCI bus instead of bridge device to break the
look in common_swizzle(). Functionally it's the same, but it's
cleaner for PC-style host bridges (nautiluses).
- Generic PCI setup changes finally went in (thanks to rmk), so that
FIXME in common_init_pci() can go.
Ivan.
<ink@jurassic.park.msu.ru>
[PATCH] alpha: nautilus_init_pci() cleanup
<ink@jurassic.park.msu.ru>
[PATCH] alpha: fix jiffies compile warning in smp.c
Fix more annoying compile problems due to wrong types
for comparing jiffies. This patch applies to alpha arch.
From Thomas Weyergraf.
Ivan.
<davem@nuts.ninka.net>
[TCP]: Forward port of 2.4.x bugfix, noticed as missing by davej@codemonkey.org.uk.
In tcp_sendmsg, make sure we jump to the out label
when seglen is decremented to zero and no more iovecs remain.
This matches the do_tcp_sendpages logic and makes sure that
PSH is set correctly at the end of a write even if the write length
equals the current mss.
<sfr@canb.auug.org.au>
[SCTP]: Fix IRQ flags warnings.
<yoshfuji@linux-ipv6.org>

[SPARC64]: Uninline rwsem assembler.
<jgrimm@touki.austin.ibm.com>
[SCTP] Add icmpv6 handler to SCTP.
<hch@lst.de>
[PATCH] fix rescan warning
The prototype for scsi_rescan_device was missing and once added it's
caller doesn't compile anymore because it expects a return value..
<willy@debian.org>
[PATCH] C3000 support in sym53c8xx
This patch adds support for the HP firmware call pdc_get_initiator().
This is necessary to support the narrow SCSI port on machines such as
the C3000 which use one channel of the 896 in narrow mode and one in
wide mode. The only way to figure this out is to ask firmware how it's
configured.
<hch@lst.de>
[PATCH] aha152x tidbits
(1) fix the jiffies warnings
(2) remove the #undef MODULE braindamange for pcmcia
(3) make all methods static and move the template away from the header
<dougg@torque.net>
[PATCH] minor scsi_lib.c cleanup for 2.5.64
The following patch made the trail in /var/log/messages
a little easier to follow (for me). Just a cosmetic change.
<ambx1@neo.rr.com>
[PATCH 2.5] PnP changes to allow MODULE_DEVICE_TABLE()
This patch fixes the MODULE_DEVICE_TABLE problems, the correct code was
accidentally lost a few merges back. It is from Daniel Ritz
<daniel.ritz@gmx.ch>, below is the original message.
hello adam, jaroslav, list
this patch does:
- rename struct pnp_card_id to pnp_card_device_id
- fix all references to it
this is needed for the MODULE_DEVICE_TABLE() macro to work with pnp_card's.
jaroslav did this a while ago (changeset 1.879.79.1), but adam undid it a bit
later (changeset 1.889.202.3). but why?
w/o the patch gcc dies when compiling als100.c with the message 'storage size
of __mod_pnp_card_device_table unknown' (this is from the macro).
any reasons why i should not send this to linus?
against 2.5.65-bk

<ak@suse.de>
[PATCH] aio compat patches
The new aio emulation in x86-64 needs a few aio symbols exported.
Export them.
<ak@suse.de>
[PATCH] ACPI NUMA option fix for x86-64
The ACPI NUMA support doesn't work on x86-64 currently (no SRAT
parsing yet). Disable for now.
<baldrick@wanadoo.fr>
[PATCH] USB speedtouch: code reorganization
Remove dead code from sarlib, reorganize live sarlib code (trivial transformations).
<baldrick@wanadoo.fr>
[PATCH] USB speedtouch: trivial cleanups
<baldrick@wanadoo.fr>
[PATCH] USB speedtouch: per vcc data cleanups
Use struct list_head rather than a singly linked list in udsl_vcc_data. Reject
attempts to open multiple vccs with the same vpi/vci pair. Some cleanups too.
<baldrick@wanadoo.fr>
[PATCH] USB speedtouch: eliminate ATM open/close races
The list of open vccs is modified by open/close, and traversed by the
receive tasklet. This is the last race I know of in this driver.
<ink@jurassic.park.msu.ru>
[PATCH] USB: missing include
at least Alpha needs mm.h for "page_address".
<david-b@pacbell.net>
[PATCH] USB: usb-skeleton, usbtest use "real" device ids
I'll be switching "gadget zero" to use real product IDs
(donated by NetChip), and these are the two drivers that
will need to recognize them.
<joe@perches.com>
[PATCH] USB: usb_skeleton.c trivial fix
Remove redundant __FILE__.
<ak@suse.de>
[PATCH] x86-64 updates
Lots of x86-64 updates. Merge with 2.4 and NUMA works now. Also reenabled
the preemptive kernel. And some other bug fixes.
IOMMU disabled by default now because it has problems.
- Add more CONFIG options for device driver debugging and iommu
force/debug. (don't enable iommu force currently)
- Some S3/ACPI fixes/cleanups from Pavel.
- Set MSG_COMPAT_* in msg_flags for networking 32bit emulation.
This unfortunately still doesn't fix the fd passing problems.
- Sync PCI IOMMU code with 2.4 (minor fixes, flush less often)
- Really fix UP compilation (Pavel)
- Reenable preempt
- Fix CONFIG_DISCONTIGMEM bootup and enable. Still needs more tuning.
- Fix some bugs in topology discovery and clean code up.
- Don't put unwind tables into object files
- Some kernel debugging hooks
- Move CPU detection into early real mode code to better interact with
vesafb consoles
- Initialize mode in real mode character output
- New 32bit FPU signal save/restore
- Various fixes in FPU handling in ptrace
- Fix security holes in ptrace (32bit and 64bit)
- Fix serial ioctl (including security hole)
- Add bluetooth ioctls to 32bit emu (from sparc64)
- Correctly enable si_val in queued signals in 32bit emulation
- Rework SEM_STAT emulation. LTP still fails unfortunately.
- Fix error case in msg* emulation
- Fix debug register access from ptrace (Michal Ludvig, me)
- Fix handling of NULL arguments in 32bit execve
- Fix some error cases for 32bit readv/writev (LTP still complains)
- Remove rate control from unimplemented syscall warnings
- Fix error message for missing aperture
- Turn some APIC printks into Dprintk to make the bootup more quiet
- Some fixes for no APIC (probably still broken), add disableapic
option (untested)
- Sync K8 MCE handler with 2.4. Should work a lot better now.
- Remove never used KDB hooks
- Fix buffer overflow in command line copying
- Merge from i386: use separate status word for lazy FPU state
- Don't force the IOMMU for dma masks < 4GB.
- Print backtrace in Sysrq-T (from Andrea)
- Merge from i386: fix FPU race in fork.
- Disable NX mode by default for now
- Rewrite dump_pagetable
- Fix off by one bug in ioremap (i386 merge)
- Merge from i386: handle VIA pci bridge bugs
- Disable NUMA ACPI support (no SRAT support yet)

[PATCH] USB: Compiler error in cdc-acm when DEBUG defined
<randy.dunlap@verizon.net>
[PATCH] USB: usb/misc/emi26.c stack reduction
Reduces stack usage in emi26_load_firmware().
<greg@kroah.com>
[PATCH] USB: fix Makefile to allow usb midi driver to be built if it's the only class driver selected.
<mochel@osdl.org>
driver model: don't define DEBUG in base.h
<mochel@osdl.org>
driver model: Make sure we initialize drivers' class_list.
<mochel@osdl.org>
driver model: Fix error handling in sysfs registration
From Matt Dobson:
The cpu, memblk, and node driver/device registration should be a little
more clean in the way it handles registration failures. Or at least
*consistent* amongst the topology elements. Right now, failures are
either silent, obscure, or leave things in an inconsistent state.
<ambx1@neo.rr.com>
ALSA SB16 PnP Update
Updates the driver to the new pnp apis. Although it has only been tested
for compiliation, it is an improvement over the existing broken code.
These changes are based on a update by Shaheed Haque <srhaque@iee.org>.
<oliver@neukum.name>
[PATCH] USB: Another memory allocation in block IO error handling path
- memory allocation in block io error code path with GFP_KERNEL
<oliver@neukum.name>
[PATCH] USB: storage device reset cleanup
> In the absence of far-reaching changes to the API, my suggestion is to
> have the emulated SCSI bus reset code in usb-storage do nothing but log an
> error message and return an error code. For the time being, considering
> how infrequently these resets occur, we can simply rely on the user

OK, as the consensus seems to be that in the short run changing things
for a full reset implementation is not worth it, here's an implementation
that does the best we can do without.
It issues a reset only if we can be sure that there are no other users
of the device in question.
As the version currently in the storage driver is broken anyway,
this is a definite improvement. And it addresses the need of exporting
the probe/remove functions for storage's sake.
<oliver@neukum.name>
[PATCH] USB: storage: add logging to reset
- add logging to reset
<ambx1@neo.rr.com>
Silently Ignore if the device is already active/disabled
Some drivers will try to activate a device even though it is already
active. Instead of returning an error, the resource manager will now
just ignore this. This should solve some of the recently seen problems.
Also it doesn't make sense to return an error if the device is already
in the correct state.
<ambx1@neo.rr.com>
Increment Version Number
<nathans@sgi.com>
[XFS] Next step in bhv code cleanup - this is a start on moving quota and dmapi
into behavior layers, purging several points where these sit slap bang in
the middle of XFS code (esp. read_super). Also removes numerous #ifdef's
and a bunch of unused #define's from all over the place. More to come.
SGI Modid: 2.5.x-xfs:slinx:141499a
<nathans@sgi.com>
[XFS] In showargs, report the usrquota/grpquota option variant, which is common.
SGI Modid: 2.5.x-xfs:slinx:141511a
<mdharm-usb@one-eyed-alien.net>
[PATCH] usb-storage: LUN and isd200
This patch (developed with assistance from Jan Harkes
<jaharkes@cs.cmu.edu>) makes the LUN field of a bulk-only transport come
from a known-good source, rather than the likely-good command-byte. It
also updates the ISD200 driver to work with this change.
<mdharm-usb@one-eyed-alien.net>
[PATCH] usb-storage: initialize urb status
This patch initializes the URB status before it's used. While not
technically required, it's good programming practice (and a similar bug
just bit us on 2.4 with UHCI).
<mdharm-usb@one-eyed-alien.net>
[PATCH] usb-storage: cleanup
This patch changes some debugging output to be a bit more clear, and
removes some un-needed code -- it's no longer possible for us to have
active URBs in the disconnect path.
<mochel@osdl.org>
driver model: increase BUS_ID_SIZE to 20
From Ben Collins, for the sake of ieee1394, so the 64-bit (16 char) GUID
can be used for the bus_id.
<nathans@sgi.com>
[XFS] whitespace and code formatting changes
<greg@kroah.com>

USB: remove unneeded #include <linux/version.h>
<rmk@flint.arm.linux.org.uk>
[ARM] Fix ARM do_div() implementation
The ARM do_div() implementation was rather lax in that it only
performed a 32-bit divide. This cset fixes this oversight by
providing a 64-bit by 32-bit division in asm.
This is necessary for posix-timers to function correctly.
<j.dittmer@portrix.net>
[PATCH] i2c: fix compile bugs in tvmixer.c
Additionally I need the following patch to tvmixer.c to compile properly
with CONFIG_SOUND_TVMIXER=m. Just a /client->name/client->dev.name/g.

[ARM] Update Cyber2000fb driver for new fbcon API
This cset updates cyber2000fb (used on NetWinders) to the new
fbcon API, and adds cfbfillrect, cfbcopyarea and cfbimgblt
objects when building cyber2000fb.

[XFS] Separate the quota source into its own subdirectory ala dmapi.
Push a bunch of quota- and dmapi-specific code down into these
subdirs which previously was compiled into the core XFS code,
and don't descend into these subdirs if options config'd off.

[PCMCIA] "driver services" socket add/remove abstraction
Previously, "Driver Services" could only be called when the socket
drivers were initialized earlier. This caused an awful lot of
problems, especially when modprobe tried to load ds.ko and a pcmcia
card driver at once.
As all socket devices are registered with the driver model core as
being of "class_type pcmcia_socket_class", we can take use of that and
register them with "Driver Services" upon detection or upon
module loading of ds.c.
Also, the "I-need-two-initcalls-in-a-module"-tweak can go away.
Unfortunately, this patch reportedly breaks some RedHat pcmcia init
scritps - they relied on the failed loading of ds.c to detect that no
socket driver was loaded previously. To properly detect this, you
should take a look at the /sys/class/pcmcia_socket/devices directory.
<linux@de.rmk.(none)>
[PCMCIA] remove "init_status" from struct pcmcia_driver
As we don't have a late_initcall in ds.c any more, we can't easily
distinguish between in-kernel drivers and those built as modules. This
information was used by cardmgr to detect whether "rmmod" makes
sense. As unloading of modules seems to be deprecated behaviour anyway
in 2.5., and the current driver unloading process is IMO broken
anyway, I don't shed any tears on this lost functionality.
<linux@de.rmk.(none)>
[PATCH] convert ds.c's socekt_info_t to struct pcmcia_bus_socket
Rename socket_info_t (which is used many, many times differently

pcmcia_bus_socket" as argument instead of the socket number.

[PCMCIA] remove unused include/pcmcia/driver_ops.h
Except for dev_node_t, the contents of include/pcmcia/driver_ops.h

their drivers as pci drivers. So, move the dev_node_t to
include/pcmcia/ds.h, remove the lone in-kernel reference to
driver_ops.h, and remove the contents of driver_ops.h.

[PATCH] initcall debug code
The patch is designed to help locate where the kernel is dying during the
startup sequence.
- Boot parameter "initcall_debug" causes the kernel to print out the
address of each initcall before calling it.
The kallsyms tables do not cover __init sections, so printing the
symbolic version of these symbols doesn't work. They need to be looked up
in System.map.
- Detect whether an initcall returns with interrupts disabled or with a
locking imbalance. If it does, complain and then try to fix it up.

[PATCH] slab: fix off-by-one in size calculation
From: Manfred Spraul <manfred@colorfullife.com>
Brian spotted a stupid bug in the slab initialization:
If multiple objects fit into one cacheline, then the allocator ignores
SLAB_HWCACHE_ALIGN and squeezes the objects into the same cacheline. The
implementation contains an off by one error and thus doesn't work correctly:
For Athlon optimized kernels, the 32-byte slab uses 64 byte of memory.

[PATCH] make add_to_swap_cache() static
From: Hugh Dickins <hugh@veritas.com>
Make add_to_swap_cache static, it's only used by read_swap_cache_async;

better for add_to_swap_cache to use GFP_KERNEL than GFP_ATOMIC.

[PATCH] tmpfs truncation fix
From: Hugh Dickins <hugh@veritas.com>
Recent testing has shown that swapoff can sneak a page back into the
tmpfs page cache after truncate_inode_pages has cleaned it, before
shmem_truncate resets next_index to stop that: BUG_ON(inode->i_blocks)
in shmem_delete_inode. So call truncate_inode_pages again to be safe.
<akpm@digeo.com>
[PATCH] handle oom in tmpfs
From: Hugh Dickins <hugh@veritas.com>
move_from_swap_cache and add_to_page_cache_lru are using GFP_ATOMIC,

then fails with -ENOMEM: use blk_congestion_wait() to let kswapd in,
and repeat.

[PATCH] wait_on_buffer refcounting checks
It is generally illegal to wait on an unpinned buffer - another CPU could
free it up even before __wait_on_buffer() has taken a ref against the buffer.
Maybe external locking rules will prevent this in specific cases, but that is
really subtle and fragile as locking rules are evolved.
The patch detects people calling wait_on_buffer() against an unpinned buffer
and issues a diagnostic.
Also remove the get_bh() from __wait_on_buffer(). It is too late.

[SCTP] Fix SACK bundling bug.
sctp_packet_bundle_sack() modifies packet->size, but the local copy
of this value is not updated. The bug is that we can "put" too much
data to the skb and segfault. Also, once DATA is in the packet, set
has_sack, so we don't inadvertantly bundle a SACK after DATA.

[PATCH] scsi queueing weirdness
The queueing logic in scsi_lib looks really odd right now.
- Defers calling elv_next_request() until we actually think we can queue
something. Always want to do that, request will have been marked
REQ_STARTED after this, so block layer cannot touch it or merge to it.
- Kill the queue empty check. If elv_next_request() returned a req,
there's one to queue.

scsi_debug version 1.69 for lk 2.5.66
As people are using scsi_debug to simulate a large
number of disks to play with the dev_t expansion,
some problems have come to light.
Changelog:
- change num_devs to num_tgts
so now the user can independently modify the
number of hosts (add_host), the number of targets
per host (num_tgts) and the number of luns per
target (max_luns)
- num_tgts sets scsi_host::max_id after allowance is
made for the initiator's target id
- max_luns default changed to 1 and it is sysfs
writeable
- REPORT LUN response cleaned up. Could now possibly
generate a response indicatimg there were up to
16,384 logical units available
- clean up sense buffer generation

o Exporting symbols from modules stopped working due to confusion of
mod->num_syms and mod->num_ksyms. Rename mod->num_ksyms to mod->num_syms,
which is more logical since the associated array is called ->syms, and
for the kallsyms member use "num_symtab", since the associated array is
->symtab.

[PATCH] handle bad inodes in put_inode
From: "J. Bruce Fields" <bfields@fieldses.org>
If the NFS daemon is presented with a filehandle for a file that has
been deleted, it does an iget() in fs/exportfs/expfs.c:export_iget() and
gets a bad inode back. When it subsequently iput()s the inode, the
result is:
Mar 27 12:53:40 snoopy kernel: EXT2-fs error (device ide0(3,3)): ext2_free_blocks: Freeing blocks not in datazone - block = 18022+
01963, count = 27499
Mar 27 12:53:40 snoopy kernel: Remounting filesystem read-only
The same can happen if ext2_get_inode() returns an error - ext2_read_inode()
will return an uninitialised inode and ext2_put_inode() is not allowed to go
looking inside the bad inode.
<akpm@digeo.com>
[PATCH] monotonic clock source for hangcheck timer
From: john stultz <johnstul@us.ibm.com>
This patch, written with the advice of Joel Becker, addresses a problem with
the hangcheck-timer.
The basic problem is that the hangcheck-timer code (Required for Oracle)
needs a accurate hard clock which can be used to detect OS stalls (due to
udelay() or pci bus hangs) that would cause system time to skew (its sort of
a sanity check that insures the system's notion of time is accurate).
However, currently they are using get_cycles() to fetch the cpu's TSC
register, thus this does not work on systems w/o a synced TSC.
As suggested by Andi Kleen (see thread here:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0302.0/1234.html ) I've worked
with Joel and others to implement the monotonic_clock() interface. Some of
the major considerations made when writing this patch were
o Needs to be able to return accurate time in the absence of multiple timer
interrupts
o Needs to be abstracted out from the hardware
o Avoids impacting gettimeofday() performance
This interface returns a unsigned long long representing the number of
nanoseconds that has passed since time_init().

[PATCH] bio kmapping changes
RAID5 is calling copy_data() under sh->lock. But copy_data() does kmap(),
which can sleep.
The best fix is to use kmap_atomic() in there. It is faster than kmap() and
does not block.
The patch removes the unused bio_kmap() and replaces __bio_kmap() with
__bio_kmap_atomic(). I think it's best to withdraw the sleeping-and-slow
bio_kmap() from the kernel API before someone else tries to use it.
Also, I notice that bio_kmap_irq() was using local_save_flags(). This is a
bug - local_save_flags() does not disable interrupts. Converted that to
local_irq_save(). These names are terribly chosen.
This patch was acked by Jens and Neil.
<akpm@digeo.com>
[PATCH] file limit checking simplification
From: Hugh Dickins <hugh@veritas.com>
When handling rlimit != RLIM_INFINITY, generic_write_checks tests file
position against 0xFFFFFFFFULL, and casts it to a u32. This code is
carried forward from 2.4.4, and the 2.4-ac tree contains an apparently
obvious fix to one part of it (should set count to 0 not to a negative).
But when you think it through, it all turns out to be bogus.
On a 32-bit architecture: limit is a 32-bit unsigned long, we've
already handled *pos < 0 and *pos >= limit, so *pos here has no way
of being > 0xFFFFFFFFULL, and thus casting it to u32 won't truncate it.
And on a 64-bit architecture: limit is a 64-bit unsigned long, but this
code is disallowing file position beyond the 32 bits; or if there's some
userspace compatibility issue, with limit having to fit into 32 bits,
the 32-bit architecture argument applies and they're still irrelevant.
So just remove the 0xFFFFFFFFULL test; and in place of the u32, cast to
typeof(limit) so it's right even if rlimits get wider. And there's no
way we'd want to send SIGXFSZ below the limit: remove send_sig comment.
There's a similarly suspicious u32 cast a little further down, when
checking MAX_NON_LFS. Given its definition, that does no harm on any
arch: but it's better changed to unsigned long, the type of MAX_NON_LFS.

[PATCH] tmpfs 6/6: percentile sizing of tmpfs
From: CaT <cat@zip.com.au>
What this patch does is allow you to specify the max amount of memory tmpfs
can use as a percentage of available real ram. This (in my eyes) is useful
so that you do not have to remember to change the setting if you want
something other then 50% and some of your ram goes.
Hugh redid the arithmetic to not overflow at 4GB; the particular order of
lines helps RH's gcc-2.96-110 not to get confused in the do_div. 2.5 can use
totalram_pages. Update mount options in tmpfs Doc.
There's an argument that the percentage should be of ram+swap, that's what
Christoph originally intended. But we set the default at 50% of ram only, so
I believe it's more consistent to follow that precedent.

[PATCH] struct stat - support larger dev_t
From: Andries.Brouwer@cwi.nl
Below a patch that changes struct stat for a number of
architectures. Maintainers, please watch carefully.
Struct stat is used to transfer information from kernel
to user space on a stat() system call.
It has fields st_dev, st_rdev.
The size of these fields is in principle unrelated to
the size of a dev_t in user space or the size of a
dev_t or kdev_t in kernel space.
It is just the "capacity" of the channel.
The actual amount of useful information is the minimum
of the four sizes (kernel dev_t, kernel kdev_t,
user dev_t, width of stat st_dev, st_rdev fields).
The goal of this patch is to make sure that the stat() and stat64()
system calls transmit at least 32 and 64 bits, respectively.
This is achieved by using the padding that was present already.
We fail when no padding was present, or when the padding is on
the wrong side (after the field, while the machine is big-endian).
alpha: stat: uses unsigned int, 32 bits
arm: stat: uses unsigned short - bad.
The padding is on one side, which means that this can
be made into unsigned long only on little endian systems.
FIXED - unless __ARMEB__.
stat64: used unsigned short - FIXED, now unsigned long long.
cris: stat: used unsigned short - FIXED, now unsigned long
stat64: used unsigned short - FIXED, now unsigned long long.
i386: stat: used unsigned short - FIXED, now unsigned long
stat64: used unsigned short - FIXED, now unsigned long long.
ia64: stat: uses unsigned long, 64 bits
m68k: stat: used unsigned short - bad, but this cannot be fixed
since m68k is big-endian, and the available padding is on
the wrong side. NOT FIXED.
stat64: used unsigned short - FIXED, now unsigned long long.
mips: stat: uses dev_t which is unsigned int, 32 bits
stat64: used unsigned long, 32 bits. NOT FIXED.
(There is padding on one side, so this can be fixed if __MIPSEL__.)
mips64: stat: uses dev_t which is unsigned int, 32 bits
parisc: stat: uses dev_t, 32 bits
stat64: uses unsigned long long, 64 bits
ppc: stat: uses dev_t which is unsigned int, 32 bits
stat64: unsigned long long, 64 bits
ppc64: stat: uses dev_t which is unsigned long, 64 bits
stat64: uses unsigned long, 64 bits
sparc: stat: uses unsigned short, no padding. NOT FIXED.
stat64: used unsigned short - FIXED, now unsigned long long.
sparc64:stat: uses dev_t which is unsigned int, 32 bits
stat64: used unsigned short - FIXED, now unsigned long long.
s390: stat: used unsigned short, big-endian, padding on the wrong side,
NOT FIXED.
stat64: used unsigned short - FIXED, now unsigned long long.
s390x: stat: uses unsigned long, 64 bits
sh: stat: used unsigned short, but padding maybe on wrong side.
NOT FIXED.
stat64: used unsigned short - FIXED, now unsigned long long.
v850: stat: used __kernel_dev_t.
BUG: NEVER use __kernel types in a user space interface.
Replaced the types. FIXED - now unsigned int - 32 bits.
stat64: FIXED - now unsigned long long - 64 bits.
x86_64: stat: uses unsigned long, 64 bits
So, on most architectures we achieve the aim of 32 bits for stat,
64 bits for stat64. On all architectures we achieve at least
16 bits for stat, 32 bits for stat64.

[PATCH] sync dirty pages in fadvise(FADV_DONTNEED)
This changes the fadvise(FADV_DONTNEED) operation to start async writeout of
any dirty pages in the file.
The thinking is that if the application doesn't want to use those pages in
the future, we may as well get IO underway against them so they can be freed
up on the next call to fadvise().
The POSIX spec does not go into any detail as to whether this is the right or
wrong behaviour.
This provides a nice way for applications whihc are writing streaming data
(the main users of fadvise) to keep the amount of dirty pagecache under
control without having to resort to system-wide VM tuning.
It also provides an "async fsync()". If the application passes in a length
of zero, fadvise will start async writeout of the pages, but will not
invalidate any of the file's pagecache.

[PATCH] add vt console scrollback ioctl
From: Samuel Thibault <Samuel.Thibault@ens-lyon.fr>
There is no way for a braille device driven by brltty (userland root-owned
daemon) to scrollback the virtual console, the only way is to use the pc
keyboard. A very simple TIOCLINUX ioctl meets this need (tested).
Also add a command for bringing the last console to the top, as keyboard.c's
lastcons() does when pressing alt - down arrow.

[PATCH] real_lookup race fix
From: Maneesh Soni <maneesh@in.ibm.com>
Here is a patch to use seqlock for real_lookup race with d_lookup as suggested
by Linus. The race condition can result in duplicate dentry when d_lookup
fails due concurrent d_move in some unrelated directory.
Apart from real_lookup, lookup_hash()->cached_lookup() can also fail due
to same reason. So, for that I am doing the d_lookup again.
Now we have __d_lookup (called from do_lookup() during pathwalk) and
d_lookup which uses seqlock to protect againt rename race.
dcachebench numbers (lower is better) don't have much difference on a 4-way
PIII xeon SMP box.

[PATCH] remove dparent_lock
The big SMP machines are seeing quite some contention in dnotify_parent()
(via vfs_write). This function is hammering the global dparent_lock.
However we don't actually need a global dparent_lock for pinning down
dentry->d_parent. We can use dentry->d_lock for this. That is already being
held across d_move.
This patch speeds up SDET on the 16-way by 5% and wipes dnotify_parent() off
the profiles.
It also uninlines dnofity_parent().
It also uses spin_lock(), which is faster than read_lock().
I'm not sure that we need to take both the source and target dentry's d_lock
in d_move.
The patch also does lots of s/__inline__/inline/ in dcache.h

[PATCH] Add less-severe assert-failure form for ext3.
From: Stephen Tweedie <sct@redhat.com>
Add a new form of assert failure in ext3 which allows us to flag events which
are *usually* bugs, but which can be legally triggered in the presence of IO
failures. Don't panic the kernel on such errors unless we've defined
#JBD_PARANOID_IOFAIL, which will normally be set only for testing purposes.

[PATCH] Fix jbd assert failure on IO error.

[PATCH] ext3_mark_inode_dirty() speedup
ext3_mark_inode_dirty() (and several other callers) use the
ext3_reserve_inode_write() and ext3_mark_ioc_dirty() pair for journalling an
inode's backing block.
Because ext3_reserve_inode_write() gets journalling access to the block there
is no need for ext3_mark_iloc_dirty() to do it as well.
This change reduces the overhead of a write() from 2.7 microseconds to 1.95
on a 2.7G P4.
<akpm@digeo.com>
[PATCH] ext3_commit_write speedup
For an appending write, ext3_commit_write() will call the expensive
ext3_mark_inode_dirty() twice. Once in generic_commit_write()'s extension of
i_size and once in ext3_commit_write() itself where i_disksize is updated.
But by updating i_disksize _before_ calling generic_commit_write() these can
be piggybacked.
The patch takes the overhead of a write() from 1.96 microseconds down to
1.63.
<akpm@digeo.com>
[PATCH] ext3: create a slab cache for transaction handles
ext3 allocates and frees at least one handle structure for each system call.
kmalloc and kfree are apparent in the profiles.
Adding a slab cache for these objects takes the overhead for a write() from
1.63 microseconds down to 1.56.

[PATCH] ext3 journal commit I/O error fix
From: Hua Zhong <hzhong@cisco.com>
The current ext3 totally ignores I/O errors that happened during a
journal_force_commit time, causing user space to falsely believe it has
succeeded, which actually did not.
This patch checks IO error during journal_commit_transaction. and aborts
the journal when there is I/O error.
Originally I thought about reporting the error without doing aborting the
journal, but it probably needs a new flag. Aborting the journal seems to be
the easy way to signal "hey sth is wrong..".

[PATCH] smp_call_function needs mb()
We really need a memory barrier in smp_call_function(), so that the

This seems to be true on some old (and arguably broken) hardware where
the IPI generation and reception doesn't synchronize enough.

[PATCH] IPMI driver version 19 release
This fixes some performance problems. Some vendors implement firmware
updates over IPMI, and this speeds up that process quite a bit.
* Improve the "send - wait for response - send -wait for response -
etc" performance when using high-res timers. Before, an ~10ms delay
would be added to each message, because it didn't restart the timer
if nothing was happing when a new message was started.
* Add some checking for leaked messages.

[PATCH] acpi compile fix
ACPI is performing a spin_lock() on a `void *'. That's OK when spin_lock is

So cast it to the right type. It really should be fixed not to use opaque
handles, though.

[PATCH] bk - fix oprofile for pm driver register
OK, so I screwed up - didn't notice the late_initcall() that was

I think the built-in case is OK: oprofile/ is after kernel/ in the link
order. I tested that too.

[PATCH] linux-2.5.66-signal-cleanup.patch
Here is the cleanup patch I promised back in February. Sorry it took a
while.
The effects should be purely cosmetic in 2.5.66. However, the new
interface for the proper way to send thread-specific of process-global
signals from inside the kernel is needed for correct implementation of
some fixes to timer stuff that Ulrich told me about.
This cleans up some obsolete comments and macros in kernel/signal.c,
restores send_sig_info to its original behavior, and adds a global entry
point send_group_sig_info. I checked all the uses of send_sig and
send_sig_info and changed a few to send_group_sig_info.
I think it would be cleanest if the whole mess of *_sig* entry points were
reduced to two or three, but I did the change that minimized the number of
callers I had to fix up.
There should be no discernible difference, since the 2.5.66 send_sig_info
function did group semantics for those signals by number already. The only
exception to that is pdeath_signal, which I guess can be any signal number
but I deemed ought to be process-wide.
I did not change any of the calls using SIGKILL, though that does have
process-wide semantics. There is no need to change it since SIGKILL always
kills the whole group, though the code path for send_sig(SIGKILL,...) calls
in multithreaded processes will be different now.

[PATCH] kill blk_queue_empty()
This finally kills of blk_queue_empty(). This is similar to the patch I
recently sent to fix the SCSI logic as well. A lot of drivers are doing
this in our core, mainly because that is the way they always did it:
start_queue:
if (blk_queue_empty(q))
return;
rq = elv_next_request(q);
if (!rq)
return;
Patch simply removes the blk_queue_empty() check, and adds a check for
!rq return from elv_next_request() if the driver didn't already do that.
Additionally, the AS io scheduler can return NULL from
elv_next_request() if it thinks this is best. This way we are also
prepared for that to work well.
Patch was done by Nick Piggin.

[PATCH] generic HDLC update
This version fixes:
- missing rtnl_lock()/rtnl_unload() bug on unregister_hdlc_device
- N2, C101: interrupt handler now works under high IRQ load from other

sometimes stop after reaching "work limit")
This is production-tested on devices I have access to (N2, C101, PC300,
PCI200SYN).
<torvalds@home.transmeta.com>
The irq vector offset should spread the irq's out evenly, which
implies that it should vary between 0-7, not any further (the
higher bits are done by updating current_vector by 8).
This also means that we don't have any overflow condition.
