<anton@samba.org>
ppc64: Add readahead ioctls
<mochel@osdl.org>
kobjects: minor updates
- check if subsystem is NULL during subsys_get().
- Don't increment parent's reference count before we check if we have a
valid kobject during kobject_add()
- Do kobject_add() in subsys_register(), instead of kobject_register(),
since we've already done kobject_init().
<mochel@osdl.org>
fs/partitions/check.c - minor updates
- remove extraneous header.
- check for error when doing kobject_add() for gendisk.
<mochel@osdl.org>
driver model: eliminate struct device_driver::bus_list
- use list in embedded kobject instead.
- remove struct bus_list::drivers; use ::drvsubsys.
<shaggy@shaggy.austin.ibm.com>
JFS: In jfs_extendfs, brelse was being called with wrong bufferhead
<mochel@osdl.org>
driver model: get correct pointer of interfaces from data
When adding interface data for an object, we were getting the pointer of
the interface from data->kobj.subsys, when we should have just been getting
it from data->intf.
<mochel@osdl.org>
Deprecate /proc/pci
As discussed on lkml, /proc/pci is past his functional usefulness, and has
been obviated by lspci(8). lspci can provide all the same information, plus
so much more. And, it doesn't rely on having an in-kernel database of PCI
names.
This change does:
- Create config parameter: PCI_LEGACY_PROC.
- Add deprecation notice to Kconfig text.
- Wrap code in #ifdef in drivers/pci/proc.c
This does nothing with the names database, though we would probably be
better off removing that as well. The PCI name field is used now only so
drivers can print a useful message on startup - hardly a justification for
60kB + increase in size..
<rob@osinvestor.com>
[SPARC]: Add param section to linker script.
<tcallawa@redhat.com>
[SUNLANCE]: Add missing asm/machine.h include for sun4 builds.
<wd@denx.de>
PPC32: Add support for SPI and RISC timers to the MPC8xx
commproc.h file.
<wd@denx.de>
PPC32: Minor updates for a few MPC8xx platforms.
<rth@are.twiddle.net>
[ALPHA] ET_REL modules support.
<anton@samba.org>
ppc64: restore FB ioctls
<rth@are.twiddle.net>
[ALPHA] Export scr_memcpyw for modular fbcon.
<rmk@flint.arm.linux.org.uk>
[ARM] Fix up location of Acorn font file
The Acorn font file is used by the decompressor on some machines.
It moved location recently - so this cset fixes up the reference
to it.
<rmk@flint.arm.linux.org.uk>
[ARM] Fix child-structure named initialisers.
Tricks like struct foo foo = { .bar.baz = 5, }; don't work. We must
initialise child-structure members within their own block - ie,
struct foo foo = { .bar = { .baz = 5, }, };
<rmk@flint.arm.linux.org.uk>
[ARM] Semaphore functions need to be memory barriers.
<rmk@flint.arm.linux.org.uk>
[ARM] Add restart block infrastructure
Add the necessary infrastructure to handle restartable syscalls via
the restart_block method. This isn't perfect, since we are unable
to modify the syscall number with ARM executables (it's typically
encoded into the instruction in the text segment) so instead we
build some code on the user space stack.
There is a potential problem - what happens if we are sleeping,
someone suspends us, resume (we continue to sleep via the restart
block method) suspend and then resume again? We will build two
sets of restart code on the user stack. This is probably a little
inefficient, but it should be harmless.
<rmk@flint.arm.linux.org.uk>
[ARM] Add __param section for kernel/module parameters.
<rmk@flint.arm.linux.org.uk>
[ARM] Fix up {__,}put_user macros
- Make them work on 64-bit quantities
- clean up use of local pointers to prevent multiple references
to the pointer (which may have side effects.)
Note that this causes __put_user to produce a warning each time
a pointer is passed as the first argument, since the 64-bit
implementation tries to cast a 32-bit pointer to a 64-bit long.
The fix for this warning waiting for comments from the GCC
community.
<wd@denx.de>
PPC32: Make the MPC8xx FEC driver PHY selection configurable.
<wd@denx.de>
PPC32: Add code to support the AMD AM79C874 PHY to the MPC8xx FEC driver.
<rth@are.twiddle.net>
[TGAFB] Implement the fb_fillrect hook.
<rmk@flint.arm.linux.org.uk>
[ARM] Allow arch/arm/kernel/asm-offsets.s to be regenerated
<rmk@flint.arm.linux.org.uk>
[ARM] Convert semaphore initialisers to C99 syntax.
The semaphore initialisers were using the old gcc syntax. Add
sema_count() implementation for the sa11x0 audio implementation.
<rmk@flint.arm.linux.org.uk>
[ARM] IOP310 build fixes
Add <asm/arch/iop310.h> include, needed for platform implementation of
architecture private __virt_to_bus / __bus_to_virt.
<rmk@flint.arm.linux.org.uk>
[ARM] Allow arch/arm/kernel/bios32.c to build for iop310
bios32.c uses outb(), and therefore should have asm/io.h included.
<rmk@flint.arm.linux.org.uk>
[ARM] Make jornada720 build again
- Add missing include files.
- Fail to set pcmcia socket state for invalid socket numbers.
- Fix locla_ typo.
- Make pcmcia_jornada720_exit __devexit, not __exit.
- Don't initialise jornada720 machine specifics if not running
on jornada720.
<rmk@flint.arm.linux.org.uk>
[ARM] Minor fixes to drivers/pcmcia/sa1111_generic.c.
Only set IRQ type after a successful request_irq().
Driver now known as sa1111-pcmcia in driverfs.
<rmk@flint.arm.linux.org.uk>
[ARM] Fix ups for ARM generic dma mapping interface
This brings the ARM dma mapping functionality into line with
the current generic interface, allowing any struct device to
be passed into the dma_* functions.
Further cleanups will be possible when the USB layer is
converted to use the dma_* API.
<rmk@flint.arm.linux.org.uk>
[ARM] Sanitise sa1111 and neponset device driver names.
<rmk@flint.arm.linux.org.uk>
[ARM] Update mach-types
<rmk@flint.arm.linux.org.uk>
[ARM] Add basic support for enable/disable_irq_wake.
<rmk@flint.arm.linux.org.uk>
[ARM] Add support for IRQ-based wakeup for SA11x0 CPUs
This patch adds support for enable/disable_irq_wake for the SA11x0
CPUs, allowing drivers or other code to select which IRQs are able
to wake the CPU from sleep mode.
<rmk@flint.arm.linux.org.uk>
[ARM] Add IRQ wake support for SA1111 PS/2 interfaces.
<rth@are.twiddle.net>
[TGAFB] Implement the fb_copyarea hook.
<rth@are.twiddle.net>
[MODULES] Fix compiler warning wrt try_module_get when
modules are disabled.
<rth@are.twiddle.net>
[FB] Re-add fb_readq for non-sparc.
This was originally added in rev 1.26.1.2, then dropped
during a merge in rev 1.33. Please be more careful with
those merges, people.
<anton@samba.org>
ppc64: eliminate the rest of the __kernel_..._t32 typedefs from Stephen Rothwell
<anton@samba.org>
ppc64: update
<adaplas@pol.net>
[AGPGART]: early agp init fix
intel_agp_init() must not be declared static for explicit early
initialization to work (ie i810fb).
<davej@codemonkey.org.uk>
[AGP] add agp_num_entries() function to determine GATT table size - reserved IOMMU entries.
Currently, only the K8 GART needs this, but this is cleaner than
exporting the agp_reserved_memory variable.
<torvalds@home.transmeta.com>
Fix befs/romfs breakage from vfs.h cleanups by Christoph.
Noted by Adrian Bunk and Adam Richter
<davej@codemonkey.org.uk>
[AGP] Move the VIA KT400 to its own driver.
Right now its the only VIA AGP 3.0 chipset. At some point in
time it may become via-agp3.c, but until then its cleaner to
seperate this from the VIA AGP 2.0 driver.
The 2.0 driver will still work on a KT400 with a 2.0 compliant graphic
card present. If the 2.0 driver finds the bridge in 3.0 mode, it aborts.
Likewise, the 3.0 driver will abort if the bridge is in 2.0 mode.
Confused yet?
<davej@codemonkey.org.uk>
[AGP] Add debug info to failure path of AGP 3.0 rate enabling
<daniel.ritz@gmx.ch>
[PATCH] Fix kallsyms stem compression crash
The attached patch fixes the crash top or cat /proc/*/wchan produces
when using KALLSYMS it's a buffer overrun that should not happen.
Based on patch by andi kleen.
<davej@codemonkey.org.uk>
[AGP] VIA KT400 AGP 3.0 aperture size decoding.
<sfr@canb.auug.org.au>
[PATCH] x86 savesegment() cleanup
"savesegment()" is declared in multiple places. Clean up and declare
it just once in <asm/system.h>
<mj@ucw.cz>
[PATCH] PCI IDs update
This brings pci.ids in your BK tree in sync with my database.
I've merged changes from both 2.4 and 2.5 with direct submissions to my
repository and deleted a few entries which are obviously wrong.
<rusty@rustcorp.com.au>
[PATCH] Modules: fix plt sections
Use ".init.plt" section consistently, and mark plt sections executable.
<davej@codemonkey.org.uk>
[AGP] Flesh out the VIA KT400 driver some more.
<davej@codemonkey.org.uk>
[AGP] VIA VT8235/P4X400 GART support
(based upon 2.4 patch from Richard Baverstock <beaver@gto.net>)
<davej@codemonkey.org.uk>

[PATCH] better compat_jiffies_to_clock_t
By a suggestion from David Mosberger: use this new version of
compat_jiffies_to_clock_t, which is more appropriate on 64-bit hosts
that don't have overflow issues.
It does better rounding and will not fail if COMPAT_USER_HZ > HZ.
<rth@are.twiddle.net>
[ALPHA] Distribute the irq and extra device init routines in
arch/alpha/kernel/ to the config options that need them. Fix
a few build problems for XLT and RX164.
<rth@are.twiddle.net>
[ALPHA] Makefile cleanup from Sam Ravnborg <sam@ravnborg.org>.
<rusty@rustcorp.com.au>
[PATCH] Use sh_entsize for ELF section offsets
sh_link is a 32-bit field on 64 bit archs, so a bad choice to store
module section offsets, and also INIT_OFFSET_MASK is out of range.
So switch to using sh_entsize instead.

<kai@tp1.ruhr-uni-bochum.de>
ISDN/HiSax: Fix compilation for !CONFIG_ISAPNP
Make hisax compile for CONFIG_ISAPNP not set.
The recent PnP API changes broke HiSax completely if CONFIG_ISAPNP is
set, now it at least compiles again w/o ISAPnP support.
<kai@tp1.ruhr-uni-bochum.de>
ISDN/HiSax: Remove unused B-Channel callbacks
The B-Channel callbacks are only used when a common chipset driver
is used by multiple hardware drivers. Remove the dummy/unused
functions for the other cases.
<kai@tp1.ruhr-uni-bochum.de>
ISDN/HiSax: un-virtualize W6692 B-Channel access
The callbacks to read/write B-Channel registers are only used in
w6692.c itself, so we can just call the appropriate functions
directly instead of going through the function pointers.
<kai@tp1.ruhr-uni-bochum.de>
ISDN/HiSax: Helper functions for B-Channel {read,write}_reg()
As a preparation for moving the B-Channel access functions into
a ops struct, introduce inline helper functions for using them.
<kai@tp1.ruhr-uni-bochum.de>
ISDN/HiSax: Move BC_{Read,Write}_Reg into struct bc_hw_ops
Instead of having the B-Channel callbacks directly in struct
IsdnCardState, use an struct bc_hw_ops.
<kai@tp1.ruhr-uni-bochum.de>
ISDN/HiSax: Un-virtualize D-channel access in hfc_2bds0.c
The D-channel access functions are only used in hfc_2bds0.c itself,
so no need to go through function pointers.
<kai@tp1.ruhr-uni-bochum.de>
ISDN/HiSax: Un-virtualize D-channel access in w6692.c
The D-channel access functions are only used in w6692.c itself,
so no need to go through function pointers.
<kai@tp1.ruhr-uni-bochum.de>
ISDN/HiSax: Helper functions for D-Channel {read,write}_reg() etc
As a preparation for moving the B-Channel access functions into
an ops struct, introduce inline helper functions for using them.
<kai@tp1.ruhr-uni-bochum.de>
ISDN/HiSax: Move isac{read,write}{,fifo} into struct dc_hw_ops
Abstract the D-Channel access operations into a struct dc_hw_ops.

[PATCH] hugetlbfs deadlock
Missing "unlock_page()" noticed by dada1
<hch@infradead.org>
[PATCH] Fix PCMCIA SCSI driver build
Update the drivers/scsi/pcmcia directory to the new build system.
<davej@codemonkey.org.uk>
[AGP] P4X333 uses same northbridge as P4X400
Also renumber it. (The previous patch used the number of the southbridge by mistake)
<ak@suse.de>
Fix x86-64 AGPGART/IOMMU compilation.
<hugh@veritas.com>
[PATCH] I/O APIC confusion
Dell 2600 could not bring up its MPT Fusion and hung there:
I/O APIC #7 at 0xFEC82000 was muddled with #8 at 0xFEC82800,
because the IO_APIC_BASE fixmap macro assumed page boundary.
No longer do I think all those I/O APIC messages at startup
a waste of log buffer!
<hugh@veritas.com>
[PATCH] demystify do_boot_cpu stack
Anyone experimenting with different THREAD_SIZE or PAGE_SIZE on i386
runs into magical mystery numbers in do_boot_cpu esp initialization.
Remove those and use the same stack top in startup_32 as thereafter.
Oh, and what's that phys_to_virt(8192)? Goodness! it's actually the
trampoline_base we (hopefully) got from early alloc_bootmem_low_pages.
Yes, could do with a lot more cleanup, but I'll stick here for safety.
<sfr@canb.auug.org.au>
[PATCH] compat_flock: generic
This moves struct flock32 to struct compat_flock and consolidates the
functions used to copy it to/from user mode.
This is just the generic part - subarchitectures will follow.
<sfr@canb.auug.org.au>
[PATCH] compat_flock: ppc64

ips driver 1/3: remove 2.2 kernel compat code
This rather large patch removes the old compatibility
code and ifdefs for compiling the driver against a
2.2 kernel.
<David_Jeffery@adaptec.com>
ips driver 2/3: adapter error handling fixes
This patch fixes three previously fatal error
cases during card initialization. Non-fatal
errors for a battery pic reprogram, unitialized
nvram, or an unitialized card are now correctly
handled.
There is also a one line fix where a pci_alloc
call was being given a NULL pointer instead of
the pci dev.
<David_Jeffery@adaptec.com>
ips driver 3/3: code cleanup
This patch does 3 small cleanups.
It moves some of the init code into a new helper function.
It simplifies the S/G path by using the scsi_to_pci_dma_dir()

It deletes unused defines and structs from ips.h.

PPC32: Fix so that we don't use the 6xx-specific idle code on POWER3.
<paulus@samba.org>
PPC32: remove support for IBM iSeries machines.
All the iSeries machines that can run Linux are 64-bit PowerPC
machines and are now supported by the ppc64 kernel. Since no-one
is interested in maintaining the iSeries support in the ppc32
kernel, I am removing it.
<paulus@samba.org>
PPC32: create arch/ppc/platforms/4xx/Kconfig and move the config
options relating to 4xx-based boards there.
<paulus@samba.org>
PPC32: Fix an oops that could happen if ptrace caused a page fault.
We were using the virtual address for cache flushing in
update_mmu_cache, which is ok if the address is in the current mm,
but if it isn't we have to do something different, namely,
flush using the physical address.

fix ide-cd/ide-scsi oopses after module unload
In 2.5 (the bug's been there since 2.5.42), rmmod:ing a
modular IDE subdriver like ide-cd or ide-scsi and then
rebooting causes an oops in device_shutdown(). This is because
the IDE layer doesn't reset the drive->gendev.driver pointer
that it previously set up to point to data structures in the
subdriver module. device_shutdown() sees a non-NULL ->driver,
dereferences it, and oopses.
The patch below for 2.5.54 fixes two generic bugs related to
unloading of modular IDE subdrivers, and one specific to ide-scsi:
1. ata_attach() needs to set drive->gendev.driver = NULL
when no specific driver claims the drive. This prevents a
drive previously owned by a subdriver module from keeping
its ->gendev.driver pointing into that module.
2. ide_unregister_driver() needs to unregister &driver->gen_driver;
this is to balance the corresponding register call in
ide_register_driver(). [This part of the patch is originally
by Patrick Mochel.]
3. ide-scsi.c abuses ide_driver_t's busy field as a counter
while the field in fact is a single-bit boolean. This causes
the busyness of the driver to be incorrect while the driver
is active. (From my recent patch for 2.4.20-ac2/2.4.21-pre2.)

ISDN/HiSax: Un-inline hscx_irq.c
Each driver for HSCX based cards defined some hardware access macros
and #include'd hscx_irq.c. Instead, we now add the needed routines to
the corresponding bc_hw_ops and use regular function calls. It's a slight
bit less efficient, but shouldn't be noticable.
<mochel@osdl.org>
kobject: Introduce struct kobj_type.
This is the first step in morphing struct subsystem into something meaningful.
A subsystem is defined simply as a list of kobjects of a certain type, which
is far too generic. A subsystem should be representative of a large entity
of code (i.e. a subsystem of the kernel), not just a simple list.
This changeset:
- Creates struct kobj_type, a descriptor of the type a kobject is embedded
in.
- Extracts the fields that are specific to a particular object type from
struct subsystem and puts them in struct kobj_type, which are
- the object's release method.
- the sysfs operations for the object type.
- the default attributes of the object type.
- Adds ptr to struct kobject to point to its type descriptor.
- Converts the existing subsystem definitions to define struct kobj_type.
struct kobj_type's are not registered, as they do not have any explicit
representation in the object hierarchy, nor do they have any fields that
need runtime initialization.
A kobject's ktype should be set when it is registered, like its subsystem.
Note this obviates the need for defining a struct subsystem when an object
type does not need to be kept in a global list.
<kai@tp1.ruhr-uni-bochum.de>
ISDN/HiSax: Un-inline jade_irq.c
Same thing which just happened to hscx_irq.c - Use the struct

driver model: clean up struct bus_type a bit.
- Remove devices list, in favor of using the list in the subordinate

- Rename devsubsys to 'devices' and drvsubsys to 'drivers'.
- Use bus's rwsem when iterating over drivers, instead of the
subordinate driver subsystem's. (We use that one when adding the
driver, and binding it to devices).
<kai@tp1.ruhr-uni-bochum.de>
ISDN/HiSax: "ops" structure for the shared xmit handling
When separating out the duplicated xmit handling, we were lucky that
we could reuse BC_Send_Data for our purposes. Introduce a more
extensible "struct bc_l1_ops" instead, and initialize that in
the code that provides the functionality, not in the users.
<mochel@osdl.org>
driver model: clean up struct device_class a bit.
- Remove unused class_list.
- Use lists in subordinate subsystems for storing lists of devices and

- Rename 'drvsubsys' to 'drivers' and 'devsubsys' to 'devices', to be more
meaningful.

[PATCH] Fix sysenter iopl
This patch fixes the handling of IOPL when sysenter is used.
Currently when entering kernel mode, IOPL is not changed and it is not
presserved across context switches: thus, in the kernel, the IOPL value
is random.
This is not a problem when using iret, because it restores eflags, but
the sysexit code currently doesn't, which means that that IOPL becomes
random in user mode too which is of course not good.
This patch fixes the problem by saving eflags across context switches.
<Andries.Brouwer@cwi.nl>
[PATCH] scsi_scan.c
Wondering why my CD-writer did not have a name in sysfs, I saw

[PATCH] x86-64 updates for 2.5.54
More x86-64 updates for 2.5.54. Most noticeable change is that the
64bit X server works again.
This only changes x86-64 specific files. It requires some AGP driver
changes I'm sending separately.
- Some Makefile cleanups from Sam Ravnborg
- Make sure extended registers in 32bit processes are zeroed and not
accessible/changeable from ptrace. This is to avoid potential
security bugs with non 64bit clean 32bit emulation functions (they
often are overflow prone etc.)
- Some 32bit emulation cleanups from Stephen Rothwell
- Make copy_*_user source const to fix warnings.
- Set fs/gs to dummy values when the 64bit segment base is set to not
confuse the context switch (Karsten Keil, me)
* still one mysterious bug in this area unfortunately.
- Make MAP_32BIT for 64bit processes only map in the first 31bit,
because it is usually used to map small model code. This fixes the X
server crashes. Some cleanups in this area.
- Don't set O_LARGEFILE for 32bit open
- Handle ptregs calls from 32bit syscall correctly.
- Implement aio io_getevents for 32bit.
- Remove buggy unused command handler in nfsd 32bit emulation.
- Convert timespec in semtimedop (thanks to Anton for telling me about
this)
- Ignore long mode flag from 32bit modify_ldt. This fixes Wine, which
left it uninitialized (bug found by Karsten Keil)
- Merge with i386
- Handle new kallsyms
- Remove some superfluous bootup printks
<ak@muc.de>
[PATCH] 2.5.54 AGP driver fixes for x86-64
This is just to make x86-64 boot with IOMMU and compiled in AGP driver
again. Previously both AGP and the IOMMU code would set up an aperture,
with AGP being winner, messing up pci_map_*.
This is needed for the x86-64 update for 2.5.54 I sent earlier.
Actually using /dev/agpgart still corrupts memory unfortunately, haven't
tracked that down yet.
I also commented on some (usually 64bit, but at least one 32bit) bugs in
the driver too.
These changes should be all nops on i386.
- Export amd k8 init function for x86-64. It needs to be called early
by the iommu code. Add some comments to warn about about that (the
upcoming VIA and SIS K8 chipsets will have the same problem)
- Declare gatt table as u32 following the AGP spec.
- Comment some bugs.

[PATCH] Fix sysenter (%ebp) fault handling
Currently syscall_badsys is called to handle faults when reading the
sixth parameter in sysenter; however that routine assumes that
registers have already been pushed on the stack, and this is not the
case (in other words, it will currently try to pop beyond the end of
the thread stack).
This patch adds a new "function", syscall_fault, that saves register
and returns.
The return value is changed to EFAULT, which seems more appropriate
than ENOSYS.
<ldb@ldb.ods.org>
[PATCH] Introduce TIF_IRET and use it to disable sysexit
This patch introduces a new flag called TIF_IRET and uses it in place
of TIF_SIGPENDING when that flag is used to force return via iret.
This avoids the overhead of calling do_signal and makes the code
easier to understand.

[PATCH] knfsd: Handle -EAGAIN from exp_find properly in nfsfh.c
<neilb@cse.unsw.edu.au>
[PATCH] knfsd: Don't assume a reader on an RPC cache channel at statup.
Each cache channel remembers if there was a reader recently.
If there wasn't, then it doesn't bother with an up-call.
Currently, it initialises thinking there was a reader
recently incase the reader starts shortly afterwards. However
this causes problems when a reader doesn't start soon, and
isn't necessary as the reader can easily be started before
the cache is initialised (e.g. before nfsd is started).
<neilb@cse.unsw.edu.au>
[PATCH] knfsd: rpc/svc auth_unix tidyup
Get auth_unix_lookup (maps IP address to clientname)
to use cache_check instead of checking the various state

<neilb@cse.unsw.edu.au>
[PATCH] knfsd: Allow rpcsvc caches to provide a 'cache_show' method
This provides a /proc/sunrpc/*/content seq_file for caches to display

[PATCH] knfsd: Fixes for nfsd filesystem files
The transaction files in the 'nfsd' filesystem
stores the per-transaction response size in the per-inode
i_size, which is wrong.
With this patch a page is allocated for holding size and
request and response, so routines don't need to
copy_fromuser.
Also, some routines were allocating rather large (>1024 bytes)
stuctures on the stack for copy_fromuser into, which was not
nice and is now not needed.
Also, writeonly and write_read methods are unified in a single
transaction style interface.
Write then read performs and action and returns a response.
Write without read just performs the action and ignores response.
Read without write triggers an empty transaction which can still have
a response. That functionality will be used in a later patch.
<neilb@cse.unsw.edu.au>
[PATCH] knfsd: Change names of legacy interfaces in nfsd filesys to start with period
The nfsd filesystem provides an interface to nfsd.
Most of the current files should be considered legacy
interfaces as they are not particularly suitable for
filesystem interaction, but are required to support the
syscall interface.
This patch puts a '.' in front of all the names so they
appear as hidden names when the directory is listed.
<neilb@cse.unsw.edu.au>
[PATCH] knfsd: Add 'filehandle' entry for nfsd filesystem for looking up a filehandle
The getfh system call takes an IP address, which is only
really appropriate for AUTH_UNIX authentication.
With this interface, you call can ask for a filehandle for a
particular domain.
You write
domainname pathname maxlength
to the file, and then read back the filehandle
All strings a qword quoted.
<neilb@cse.unsw.edu.au>
[PATCH] knfsd: Add 'threads' file to nfsd filesystem to allow changing number of threads.
This uses the read-without-write style transaction files in nfsctl.
We can write a number of threads, and then read back the number of
threads that resulted, or we can just open and read in which case
we read back the number of threads without changing it.
<neilb@cse.unsw.edu.au>

[PATCH] md: Make sure yielding thread actually yields cpu when waiting for turn at reconstruct.
<neilb@cse.unsw.edu.au>
[PATCH] md: Make MD device-is-idle test check whole device, not partition.
When resyncing an array, md will back off if it detects other
activity on the device. This used to be based on the whole
device, not the partition, but recent changes made it only
check IO on the partition.
This patch causes all sync_io accounting to be done on the
whole device (bdev->bd_contains).
<neilb@cse.unsw.edu.au>
[PATCH] md: Record location of incomplete resync at shutdown and restart from there.
Add a new field to the md superblock, in an used area, to record where
resync was up-to on a clean shutdown while resync is active. Restart from
this point.
The extra field is verified by having a second copy of the event counter.
If the second event counter is wrong, we ignore the extra field.

[PATCH] devfs mount-time readdir fix and cleanup
Patch from Adam J. Richter <adam@yggdrasil.com> and
Milton Miller <miltonm@bga.com>
There's some init-time code which is supposed to read a devfs directory by
expanding the bufer until the whole directory fits. But the logic is wrong
and it only works if the whole directory fits into 512 bytes.
So fix that up, and also clean up some coding in there, and rationalise the
duplicated definition of linux_dirent64.

[PATCH] copy_page_range: minor cleanup
- Don't evaluate pfn_to_page(pte_pfn(pte)) twice.
- adjust whitespace
- rename inner variable `ptepage' to `page'. It's more logical, and
reduces collisions with the shared pagetable patch (which has to rename it
anyway, because it adds a `ptepage' which really is "the page which holds
ptes").
<akpm@digeo.com>
[PATCH] infrastructure for handling pte_chain_alloc() failures
The VM allocates pte_chains with GFP_ATOMIC, under deep locking. If that
allocation fails, we oops.
My approach to solving this is to require that the caller of page_add_rmap()
pass in a pte_chain structure for page_add_rmap() to use. Then, callers can
arrange to allocate that structure outside locks with GFP_KERNEL.
This patch provides the base infrastructure.
A common case is that page_add_rmap() will in fact not consume the pte_chain,
because an empty slot was found within one of the page's existing pte_chain
structures. So this patch provides for a special one-deep per-cpu pte_chain
cache to optimise this case of taking just one pte_chain and then immediately
putting it back.
We end up adding maybe 20-30 instructions to the pagefault path to handle the
eventuality of pte_chain allocation failures.
Lots of other design ideas were considered. This is the best I could come up
with.
<akpm@digeo.com>
[PATCH] handle pte_chain_alloc() failures
Update page_add_rmap() callers to allocate their own pte_chain structures,
and to pass those into page_add_rmap().
The swapoff path has not yet been updated and is still oopsable. The locking
there is tricky.
<akpm@digeo.com>
[PATCH] infrastructure for handling radix_tree_node allocation
radix_tree_node_alloc() uses GFP_ATOMIC, under spinlocking. If the
allocation fails then userspace sees ENOMEM and application failure occurs.
A single add_to_page_cache() will require up to six radix_tree_nodes on
32-bit machines, twice this on 64-bit machines (quadruple the worst-case
storage on 64-bit).
My approach to solving this problem is to create a per-cpu pool of
preallocated radix_tree_nodes, private to the radix-tree code.
The radix-tree user will call the new radix-tree API function
radix_tree_preload() to ensure that this pool has sufficient nodes to cover
the worst-case. radix_tree_preload() should be called outside locks, with
GFP_KERNEL so that it can run page reclaim.
If it succeeds, radix_tree_preload() will return with preemption disabled so
that the per-cpu radix_tree_node pool is protected. The user must call
radix_tree_preload_end() to terminate the transaction.
In the common case, the per-cpu pools will never be touched:
radix_tree_insert() will only dip into the pool if kmem_cache_alloc() fails.
The pools will remain full at all times. This is to optimise the fastpath -
it is just a few instructions.
This patch also removes the now-unneeded radix-tree mempool. This saves 130
kbytes of permanently allocated kernel memory. 260k on 64-bit platforms.
<akpm@digeo.com>
[PATCH] handle radix_tree_node allocation failures
This patch uses the radix_tree_preload() API in add_to_page_cache().
A new gfp_mask argument is added to add_to_page_cache(), which is then passed
on to radix_tree_preload(). It's pretty simple.
In the case of adding pages to swapcache we're still using GFP_ATOMIC, so
these addition attempts can still fail. That's OK, because the error is
handled and, unlike file pages, it will not cause user applicaton failures.
This codepath (radix-tree node exhaustion on swapout) was well tested in the
days when the swapper_space radix tree was fragmented all over the place due
to unfortunate swp_entry bit layout.
<akpm@digeo.com>
[PATCH] mempool_resize fix
David Brownell noticed this. mempool_resize() is calling kfree on a rare
path when it should be calling the pool's free function.
The patch fixes that up, and then disables mempool_resize() compilation - it
has no callers at present.

[PATCH] shrink the amount of vmalloc space reserved for kmap
Patch from Manfred Spraul <manfred@colorfullife.com>
Effectively adds another 24 megabytes of ia32 KVA.
kmap uses a 4 MB (2 MB if PAE is enabled) area for the persistant mappings.
But PKMAP_BASE is 4GB-32MB, i.e. around 28 MB are reserved for kmap (4 MB
for fixmappings).
The attached patch shrink that to 4 MB (+4MB for fixmappings) and adds a test
to check for an overlap between fixmap and kmap areas.
<akpm@digeo.com>
[PATCH] Dynamically size the pidhash hash table.
Patch from Bill Irwin. Prodding from me.
The hashtables in kernel/pid.c are 128 kbytes, which is far too large for
very small machines.
So we dynamically size them and allocate them from bootmem. From 16 buckets
on the very smallest machine up to 4096 buckets (effectively half the current
size) with one gigabyte of memory or more.
The patch also switches the hashing from a custom hash over to the more
powerful hash_long().

[PATCH] Exception table cleanup
This patch combines the common exception table searching functionality
for various architectures, to avoid unneccessary (and currently buggy)

private to module.c.
The archs provide "struct exception_table" and "search_extable": the
generic infrastructure drives the rest.

[PATCH] /proc/modules change
This changes /proc/modules to have fixed space-separated format,
independent of CONFIG options or how many module dependencies there

Old format: modname modsize [refcount [dep1] [dep2] ...]
New format: modname modsize refcount deps1,[dep2,]...
The module-init-tools have understood this format for over a month now.
This change allows us to add new fields, ie. module state, module
address, etc.

[PATCH] Fix errors making Docbook documentation
This modifies the following files: -
Documentation/Docbook/Makefile - Fix dependencies generating parportbook

[PATCH] Kernel Janitors patch to drivers_macintosh_ans-lcd.c
Working on the Linux Kernel Janitors project, and following up on Mikal
Still's work there, I'd like to submit a patch for the Macintosh ANS
LCD driver.
I believe from Mikal's Patches page that his previous patch was rejected
due to not cleaning up properly. I believe my patch addresses this issue,
by calling iounmap() to free the IO remapping created by ioremap() earlier
in the function, if the call to misc_register() fails for any reason.
Unfortunately I don't know how to get this driver to compile on my
machine, and therefore I can't even check that my patch compiles. If you
can advise me how to set my machine up to dompile these drivers, then
please get in touch =) I hope I didn't make any stupid mistakes in this

[PATCH] ip27-rtc.c create_proc_read_entry patch
As part of my work on the Linux Kernel Janitors project, cleaning up on
functions which call create_proc_*_entry and don't check for an error
return, I would like to submit my patch to arch/mips64/sgi-ip27/ip27-rtc.c.
This patch adds a printk() if misc_register fails (since that causes the
driver to fail to load, it should be logged somewhere), and checks that
create_proc_read_entry returned a valid handle. ENOENT seems to me like a
good error code to return in this case, although EBUSY is a candidate too.

[PATCH] perf.c misc_register patch
As part of my work on the Linux Kernel Janitors project, cleaning up on
functions which call misc_register and don't check for an error return, I
would like to submit my patch to drivers/parisc/kernel/perf.c
This patch simply causes the function to printk() an error and return the
error code from misc_register() if it fails. I hope this is the right
thing to do. I moved it slightly earlier in the function so I wouldn't
have to worry about undoing the side effects of perf_patch_images().

[PATCH] remove check_region from fdc-io.c version 2
This is version 2 of my proposed patch for fdc-io.c tape driver for
Linux. It
1) removes three calls to check_region using request_region instead.
2) in case of fatal error calls release_region to liberate region
resources already allocated (as pointed out by Matthew Wilcox my
first patch wasn't doing that)
Remark regarding allocation of regions in this driver:
If BROKEN_FLOPPY_DRIVER is defined the driver keeps going even if it
can't allocate one or more region resources. The driver does not
store information concerning which allocations succeeded and which
failed. When and if subroutine fdc_release_regions is called it will
then try to release all regions it normally reserves. I don't know if
this could cause any trouble in some (rare) situations?
I don't have this hardware so only compilation is tested. This patch
removes all references to check_region in this driver.

Needs <linux/string.h> for strlen()
<mochel@osdl.org>
Introduce struct kset.
struct kset is what struct subsystem should have originally been called. It
is a set of kobjects, and nothing more, with a much less confusing name than
'subsystem.'
struct kset contains an embedded kobject, making it possible to represent it
in the object hierarchy, and sysfs. This also provides a means for objects
to easily express a list of subordinate objects.
struct subsystem still exists, and contains an rwsem, which its subordinate
ksets use to protect their lists.
An arbitrary number of ksets may belong to a subsystem. A ksets specifies
the subsystem it belongs to via its ->subsys field.
struct subsystem also contains a default kset, which may be used without
having to define a separate kset.
The objects that defined subordinate subsystems (bus and class drivers) have
been converted to use subordinate ksets instead.
Note that the usage of ksets is flexible.
- ksets may contain a list of objects of any type, not just kobjects.
- The objects registered with a kset do not have to be registered.
- ksets themselves do not have to be registered. One can be used by
simply calling kset_init().
- ksets do not need a name if they are not registered.
- Note however that locking must be done manually in these cases.

[AGP] Remove bogus AGP/DRM assumptions
[Forward port of a 2.4 patch that got applied last month -- DJ]
AGP/DRM currently assume that GATT entries can be converted
to physical addresses with a simple mask. Additionally, agpgart
assumes in a couple places that the mask is ~0xfff, i.e., that
all the GART control bits are in the low 12 bits. Both assumptions
are bogus, so:
Make agp_memory.memory[] (exported from agpgart to DRM) contain physical
addresses, not GATT entries.
DRM assumes agp_memory contains GATT entries, and it converts them to
physical addresses with "paddr = agp_memory.memory[i] & mask". 460GX
requires both a shift and a mask, so exporting plain physical addresses
and a mask of ~0UL allows agpgart to add 460GX support without requiring
DRM interface changes.

[PATCH] "constfrobbing considered harmful"
The declaration of `module_frob_arch_sections' in moduleloader.h (and
the definitions in most of the module.c files) are inconsistent with the
definition in the PPC's module.c -- in the latter the first two
arguments are not declared `const', whereas everyplace else they are.
PS. secstrings can be modded to: if an arch can't handle discarding
init, it simply renames the .init sections.
<rusty@rustcorp.com.au>
[PATCH] Remove mod_bound macro and unify kernel_text_address().
Various archs (i386, m68k, s390, s390x, m68k, parisc, um, x86_64)
implement kernel_text_address. Put this in kernel/extable.c, and the
module iteration inside module.c.
Other than cleanliness, this finally allows the module list and lock
to be static to kernel/module.c (you didn't think I actually cared
about those archs did you?)
It also drops the module->init_size to zero when it's discarded, so
bounds checking is simplified (and the /proc/modules size statistic
will be more accurate, too).
<mochel@osdl.org>
kobjects: Remove kobject::subsys and subsystem::kobj.
The kobject core no longer references a subsystem directly through a kobject,
instead using the kobject's dominant kset to reference the subsystem. The
registrants of kobjects have been fixed up.
To aid in this process, a few helpers were introdcuced:
- kobj_set_kset_s(obj,subsys)
- kset_set_kset_s(obj,subsys)
- subsys_set_kset(obj,subsys)
that set the kset ptr of embedded kobjects for objects that have different
embedded types. See include/linux/kobject.h for more description and usage.
struct subsystem::kobj is also removed, relying solely on a subsystem's
embedded kset for hierarchy information. Since this requires modification
of the subsystem declarations, a helper macro has been defined:
decl_subsys(name,type)
which initializes the name and ktype fields of the subsystem's embedded
kset. All the subsystem declarations have been fixed up.

struct gendisk::list is also apparently unused, so it is removed also.

driver model: allow manual binding of devices to drivers.
This creates and exports device_bind_driver() and device_release_driver()
that allow a caller to manually bind a device to a driver. Apparantly, some

interfaces during the driver's probe() method call for the first interface.
Implementation is easy enough, since it simply involves renaming and exporting
the internal functions attach() and detach().

- Unmask XPR interrupt in transmit_chars() (per 2.4).
- Unmask XPR interrupt early in sunsab_start_tx(), as the user may have
been put to sleep by the uart api with XPR masked, and will otherwise
not be able to unmask XPR again.

[PATCH] make i386 topology caching
Patch originally by Matt Dobson. Reworked a little by me.
Stores the mappings between cpus and nodes in an array, instead of
working them out every time. Gives about 4% off systime for kernel
compile (we use these for every page allocation), and removes one
of the two only usages of apicid->cpu mapping, which is really awkward
to keep for systems with large apic spaces, and is genererally pretty
useless anyway (later patch removes).

[PATCH] changes do_boot_cpu to return an error code

[PATCH] cleanup apicid <-> cpu mapping
To be honest, I have no idea what I was smoking when I wrote this
originally, and it's kind of coincidental that it works at all currently.
We never use physical apicids after the cpus are all booted, so we should
just store the logical IDs which all subsequent things use. The only things
that were using the apicid->cpu mapping were hokey anyway, and it's hard to
maintain for machines that have a large apic addressing space (eg P4s
in clustered mode). Rips out everything except the mapping from
logical_apic_id -> cpu.
<mbligh@aracnet.com>
[PATCH] remove clustered_apic_mode from smpboot.c
This removes clustered_apic_mode from smpboot.c into subarch,

This is pretty much the last of clustered_apic_mode ... ;-)
<mbligh@aracnet.com>
[PATCH] nuke clustered_apic_mode and friends
OK, the grand finale ... NUMA-Q is now moved into subarch, so we can
kill off the last vestiges - CONFIG_CLUSTERED_APIC, clustered_apic_mode,
and smpboot.h (which only contains machine specific stuff now anyway).
the esr_disable switch was the last bit, that goes to subarch too.
If you end up with an empty smpboot.h due to patch / bitkeeper interactions,
please remove it after this ...

- Adds generic_file_aio_write_nolock() and make other
generic_file_*_write() to use it.
- Modify generic_file_direct_IO() and ->direct_IO() functions to take
"kiocb *" instead of "file *".
- Renames generic_direct_IO() to blockdev_direct_IO().
- Move generic_file_direct_IO() to mm/filemap.c (it is not
blockdev-specific, whereas the rest of fs/direct-io.c is).
- Add AIO read/write support to the raw driver.

[PATCH] bio dirtying infrastructure
In two cases (AIO-for-direct-IO and some CDROM DMA stuff which Jens
did), we need to run set_page_dirty() in interrupt context. After DMA
hardware has altered userspace pages for direct-IO reads.
But mapping->page_lock, mapping->private_lock and inode_lock are not
irq-safe. And really, we don't want to convert those locks just for this
problem.
So what we do is to dirty the pages *before* starting I/O. Then, in
interrupt completion context, check to see that they are still dirty.
If so then there is nothing to do. But if the pages were cleaned while
the direct-IO is in progress we need to redirty them. The code uses
schedule_work() for that.
Of course, we could use schedule_work() for all BIOs and pages. The
speculative dirty-before-starting-IO is just an optimisation. It's
quite unlikely that any of the pages will be cleaned during the direct
IO.
This code is basically untestable under normal circumstances, because the
relevant pages are pinned via get_user_pages(). This makes
is_page_cache_freeable() evaluate false and the VM doesn't try to write them
out anyway. But if the pages happen to be MAP_SHARED file pages, pdflush
could clean them. The way I tested this code was to disable the call to
bio_set_pages_dirty() in fs/direct-io.c.

[PATCH] AIO support for raw/O_DIRECT
Patch from Badari Pulavarty <pbadari@us.ibm.com> and myself.
This patch adds AIO support for direct-IO - O_DIRECT files, O_DIRECT
blockdevs and /dev/raw/rawN.
Also, the controlling `struct dio' is now always kmalloced, saving ~400 bytes
of stack.
The best tool for testing AIO/DIO is the modified fsx-linux in ext3 CVS.
See http://www.zip.com.au/~akpm/linux/ext3/ for details. For example:
fsx-linux -Z -A -R -W -r 512 -w 4096 foo
Running many instances of this against ext3 currently fails with incorrect
file data; some bug in the new ext3 O_DIRECT support. ext2 is OK though.

[PATCH] Reduced wakeup rate in direct-io code
We don't need to wake up the synchronous waiter for every BIO
completion - just for the final BIO.
This reduces the context switch rate of a 180 megabyte/sec read from
3500/sec to 2200/sec when performing 1400 128k I/Os per second, so it
more than halves the overhead.

ti->use was only getting incremented the first time a target type was
retrieved (bug introduced by recent hch patch).

[PATCH] dm: rwlock_t -> rw_semaphore (fluff)
Use a rw_semaphore in dm_target.c rather than a rwlock_t, just to keep

[PATCH] dm: Remove redundant error checking
bio_alloc() shouldn't fail if GFP_NOIO is used, and the bvec count is
sensible. So remove redundant error checking.

[PATCH] Fix NFS 'off by one' bug
This fixes a bug that was found using the Stanford checker.
<trond.myklebust@fys.uio.no>
[PATCH] allow arbitrary alignment of NFS read/write requests
Patch by Chuck Lever to add a new field called wb_pgbase to the
nfs_page struct. This separates the concept of file page offset from
buffer page offset, allowing NFS to specify read and write requests
into buffers at offsets that are independent of the file page
offset. It is a prequisite for direct I/O in NFS.
<trond.myklebust@fys.uio.no>
[PATCH] Cleanup for SunRPC auth code
Converts the RPC client auth code to use 'list_head' rather than a
custom pointer scheme.
Fixes a (relatively harmless) race which could cause several cred
entries to be created for the same user.

[PATCH] {get,put}_compat_timspec: generic
Andi Kleen asked for these two, so here they are. This is the generic
part of creating compat functions for timespec get/put.

[PATCH] {get,put}_compat_timspec: s390x
Here is the s390x part of the compat_timespec changes.
<kraxel@bytesex.org>
[PATCH] add tda9887 module
This adds the tda9887 i2c module to the linux kernel. This one is
needed for some TV cards. It also adds the missing #define to
audiochip.h which currently breaks the bttv build.
<kraxel@bytesex.org>
[PATCH] video-buf.c update
This updates the video-buf helper module. It changes the field handling
a bit and adds code do deal better with alternating field capture (=
capture even and odd fields to separate video buffers).
<kraxel@bytesex.org>
[PATCH] add v4l1-compat module.
This adds the v4l1-compat module. This is a module which can translate
most (old) v4l1 ioctls into the new v4l2 API. This makes it easier for
v4l2 drivers to present both old v4l and new v4l2 APIs to video4linux
applications. The saa7134 driver uses this for example.
<kraxel@bytesex.org>
[PATCH] bttv driver update.
This updates the bttv driver. Changes:
* adaptions to the video-buf changes send in a previous mail.
* adaptions to recent i2c changes in the kernel.
* first code bits the pixelview digital camera support (not
working yet).
* lots of small fixes/changes for specific TV cards.
<kraxel@bytesex.org>
[PATCH] update bttv documentation
<kraxel@bytesex.org>
[PATCH] add bt832 module
This adds a driver module for the bt832 chip. It is needed by the bttv
driver to support the Pixelview Digital Camera. The bt832 is connected
using the GPIO pins of the bt878 chip.
<kraxel@bytesex.org>
[PATCH] media/video i2c updates
This updates a bunch of i2c modules in drivers/media/video. Most of it
are adaptions to the recent i2c changes in the kernel. While being at
it I also did some other cleanups like deleting unused+dead code, using
name-based initialization for some not-yet converted structs, ...
The also has a few small fixes here and there, but no major functional
changes.
<kraxel@bytesex.org>
[PATCH] i2c update for tuner.c
This has some i2c adaptions and cleanups for the tv card tuner module.
<kraxel@bytesex.org>
[PATCH] saa7134 driver update
This updates the saa7134 driver. It adds support for a few more cards
and includes adaptions to the video-buf.c changes sent earlier.

[PATCH] Fix READ_CD fallback.
From Jens Axboe:
Only fall back to plain READ, if the device says it doesn't
support the READ_CD opcode. This is the true error for which
we want to do the fall back, not for any generic error.

[PATCH] CDROM changers timeout tweak
Been carrying this for ages..
From Jens Axboe:
This is for changers, we may need more than the default
5 second timeout for loading a disc since it may require
moving stuff around :)

[PATCH] Fix up dma_alloc_coherent with 64bit DMA masks on i386.
Cset 1.808 in 2.4 never got propagated forward to 2.5
It's pretty much the same fix as below (s/!=/</), but with the following
changes
- This was a patch to pci_alloc_consistant(), which now wants to be
dma_alloc_coherent()
- Removal of the u32 cast
