sk->num no longer exists in 2.5, use inet_sk(sk)->num
<aia21@cantab.net>
NTFS: The beginning of 2.0.8. - Major updates for handling of case sensitivity.
- Remove unused source file fs/ntfs/attraops.c.
- Remove show_inodes mount option(s), thus dropping support for
displaying of short file names.
- Remove deprecated mount option posix.
- Restore show_sys_files mount option.
- Add new mount option case_sensitive, to determine if the driver treats
file names as case sensitive or not. If case sensitive, create file names
in the POSIX namespace. Otherwise create file names in the WIN32
namespace. By default, or when case_sensitive is set to FALSE, files
remain accessible via their short file name, if it exists.
- Add additional argument to ntfs_lookup_inode_by_name() in which we
return information about the matching file name if the case is not
matching or the match is a short file name. See comments above the
function definition for details.
<aia21@cantab.net>
NTFS: Fix really dumb logic bug in boot sector recovery.
<aia21@cantab.net>
NTFS: Fix potential 1 byte overflow in fs/ntfs/unistr.c::ntfs_ucstonls().
Also, minor updates/fixes to docs and comments.
<aia21@cantab.net>
NTFS: 2.0.8 release. Major updates for dcache aliasing issues wrt short/long file names.
In order to handle the case insensitivity issues of NTFS with regards to the
dcache and the dcache requiring only one dentry per directory, we deal with
dentry aliases that only differ in case in ->ntfs_lookup() while maintining
a case sensitive dcache. This means that we get the full benefit of dcache
speed when the file/directory is looked up with the same case as returned by
->ntfs_readdir() but that a lookup for any other case (or for the short file
name) will not find anything in dcache and will enter ->ntfs_lookup()
instead, where we search the directory for a fully matching file name
(including case) and if that is not found, we search for a file name that
matches with different case and if that has non-POSIX semantics we return
that. We actually do only one search (case sensitive) and keep tabs on
whether we have found a case insensitive match in the process.
To simplify matters for us, we do not treat the short vs long filenames as
two hard links but instead if the lookup matches a short filename, we
return the dentry for the corresponding long filename instead.
In ->ntfs_lookup() we distinguish three cases:
1) @dent perfectly matches (i.e. including case) a directory entry with a
file name in the WIN32 or POSIX namespaces. In this case
ntfs_lookup_inode_by_name() will return with name set to NULL and we
just d_add() @dent.
2) @dent matches (not including case) a directory entry with a file name in
the WIN32 namespace. In this case ntfs_lookup_inode_by_name() will return
with name set to point to a kmalloc()ed ntfs_name structure containing
the properly cased little endian Unicode name. We convert the name to the
current NLS code page, search if a dentry with this name already exists
and if so return that instead of @dent. The VFS will then destroy the old
@dent and use the one we returned. If a dentry is not found, we allocate
a new one, d_add() it, and return it as above.
3) @dent matches either perfectly or not (i.e. we don't care about case) a
directory entry with a file name in the DOS namespace. In this case
ntfs_lookup_inode_by_name() will return with name set to point to a
kmalloc()ed ntfs_name structure containing the mft reference (cpu endian)
of the inode. We use the mft reference to read the inode and to find the
file name in the WIN32 namespace corresponding to the matched short file
name. We then convert the name to the current NLS code page, and proceed
searching for a dentry with this name, etc, as in case 2), above.

<dalecki@evision-ventures.com>
[PATCH] 2.5.20 airo wireless - "I can't get no, compilation..."
Fix namespace clash with proc stuff an compilation warnings.
<dalecki@evision-ventures.com>
[PATCH] ]PATCH] 2.5.20 IDE 83
- Remove last parameter from ide_dump_status. This information is now
permanently present in device->staus field, so there is not need to pass it
around.
- Patch for DVD read through ide-scsi. There is the possibility that we can get
request structures passed down, which don't have the queue field set.
At lest on the BIO code path this seems to be something worth further
investigation. Found by Adam J. Richter. (Jens?)
- Revert my change to the hostdata handling. I did get it wrong about the way
host structures are allocated by the generic SCSI layer. It plays
tricks there.
- piix driver updates by Vojtech Pavlik.
- We have a ata_out_regfile, so we should have ata_in_regfile too.
<rml@tech9.net>
[PATCH] remove wq_lock_t cruft
This patch removes the whole wq_lock_t abstraction, forcing the behavior
to be that of a standard spinlock and changes all the wq_lock code in
the tree appropriately.
Removes lots of code - always a Good Thing to me. New behavior is same
as previous behavior (USE_RW_WAIT_QUEUE_SPINLOCK unset).
<rml@tech9.net>
[PATCH] capability.c cleanup
I started looking into a couple FIXMEs in kernel/capability.c and I
ended up with a fairly largish patch (although not quite so many changes
to object code).
First, it is unsafe to touch task->cap_* while not holding
task_capability_lock. The most notable occurrence of this is sys_access
which saves the current cap_* values, changes them, does its business,
then restores them. In between all this they can change and then be
restored to old values. Unfortunately we cannot just grab the lock here
since the function can sleep - I marked this with a FIXME for now.
Second, I formalized the locking rules with task_capability_lock. I
declared the lock in include/linux/capability.h so other code can grab
it.
Finally, there is a whole boatload of code cleanup:
- remove conditional locking/unlocking - that is just gross
- don't pointlessly grab the read_lock twice
- add/remove/edit comments
- change some types (int -> pid_t, etc)
- static inline two small functions that are called only
once each
- remove two FIXMEs
- general code cleanup for readability and performance
TODO:
- fix sys_access and other cap_* accesses
- do something about the annoying oddball 5-space indentation
in kernel/capability.c !!
Patch is against 2.5.20, please apply.

[PATCH] trivial misc. scheduler cleanups
Resend of trivial bits from my scheduler tree...:
- shift cpu by 1UL not 1 to match type
- clarify various comments
- remove the barrier from preempt_schedule. This was here
because I used to check need_resched before returning from
preempt_schedule but we do not now (although should). The
barrier insured need_resched and preempt_count were in sync
now and after an interrupt that could occur.
<rml@tech9.net>
[PATCH] maintainers update
Might as well make it explicit...
Patch is against 2.5.20, please apply.
Robert Love
<rml@tech9.net>
[PATCH] make smp.c preempt-safe
The attached patch cleans up some per-CPU code in arch/i386/kernel/smp.c
that could be problematic under preemption.
The first I solve with the new get_cpu interface, for the second two I
explicitly disable preemption. I also changed 1 to 1UL in the shift to
properly match the type.
<rml@tech9.net>
[PATCH] sys_sysinfo cleanup
Looks like sys_sysinfo has not been touched in years. Among other
things, it uses a global cli() for protection; I switched it to an
existing rwlock. I also pulled it out of info.c and stuck it in timer.c
(I choose timer.c because it shares dependencies there already).
The details:
- move sys_sysinfo to kernel/timer.c from kernel/info.c:
why one small syscall got its own file is beyond me.
- delete kernel/info.c
- stop the global cli! now grab a read_lock on xtime_lock.
this is safe as we moved the write_unlock on xtime_lock
down one line to cover the calculating of avenrun.
- trivial code cleanup
<alex@ssi.bg>
[PATCH] ipchains_core netlink fix
oom-loop fixes error handling after a netlink failure - it does not do a
cleanup and it makes every next call to ip_fw_check to detect a
loop and drop the packet.
<anton@samba.org>
[PATCH] Fix for recent swap changes on 64 bit archs
This fixes two shift warnings on 64 bit archs.
<axboe@suse.de>
[PATCH] unplugging fix
Fix queue plug locking.
<trond.myklebust@fys.uio.no>
[PATCH] Fix Oops due to use of incorrect km_type in RPC socket code...
The following has been vetted with davem w.r.t. the change to
KM_SKB_DATA. Apologies for the bug...
include/asm-*/kmap_types.h:
Replace the unused km_type slot KM_SKB_DATA with
KM_SKB_SUNRPC_DATA.
net/sunrpc/xdr.c:
Replace the use of KM_USER0 with KM_SKB_SUNRPC_DATA for copying
data from an skb into the page cache when in the sk->data_ready()
callback.
<johan.adolfsson@axis.com>
[PATCH] Missing include in mm/bootmem.c
Missing include of asm_io.h in mm_bootmem.c:
Submitted this trivial patch on May 14, but nothing has happened yet.
Perhaps better chance if you took care of it.
It's needed by phys_to_virt() but it happens to work on i386 etc.
since dma.h includes io.h for that arch.
<alex@ssi.bg>
[PATCH] ipchains_core GFP_KERNEL fix
[ Made applicable with -p1 by Rusty ]
nlma fixes a call to netlink_broadcast with GFP_KERNEL ( passed to
skb_clone ) while we are in_interrupt() ( catched by a BUG() in
slab.c:1109 ).
<bhards@bigpond.net.au>
[PATCH] "General options" - begone
There is more of this janitorial work to come (eg General setup). I'm just
piecemealing it
<ghoz@sympatico.ca>
[PATCH] update to pci_quirks.c
Attached is a really trivial patch that changes an "unknown" PCI_DEVICE_ID
0x3112 to PCI_DEVICE_ID_VIA_8361 in drivers/pci/quirks.c .
It applies cleanly to 2.5.18 and 2.4.19-pre8.
<da-x@gmx.net>
[PATCH] fix NULL dereferencing in dcache.c
Unrelated to my first dcache patch, this is something more crucial
and should be applied first.
fs/dcache.c:
- handle d_alloc() returning NULL.
<kaz@earth.email.ne.jp>
[PATCH] fix for /proc operation:
I found that 'max' pointer is not updated in proc_dointvec_minmax()
and proc_doulongvec_minmax(), when I write smaller values than min to
/proc/sys entry (and val<*min++ check becomes true.)
This may lead to min/max checking of values with bogus maximum.
<peter@chubb.wattle.id.au>
[PATCH] bogus casts in ide-cd.c:
This patch against 2.5.19 gets rid of some bogus casts in ide-cd.c
In my opinion the casts as is are bugs waiting to happen.
<rusty@rustcorp.com.au>
[PATCH] Spelling
Rusty Russell <rusty@rustcorp.com.au>: Oh, I feel so violated...:
<sniff>
<rusty@rustcorp.com.au>
[PATCH] TAGS creation should go into arch dirs
Playing with arch stuff does this to you.
<wli@holomorphy.com>
[PATCH] correct zone_table comment
The comment describing the usage of zone_table[] assumes the existence
of an unsigned char page->zone field from the original implementation
of page->zone size reduction. This patch corrects the comment to
accurately describe the lookup mechanism used by page_zone() and also
to mention explicitly the sole user of the table, page_zone().
<wli@holomorphy.com>
[PATCH] duplicate decl in sched_init()
I found this one while trying to straighten out bootstrap ordering
issues elsewhere.
There appears to be a duplicate declaration of rq in sched_init().
This removes the nested declaration and otherwise leaves things alone.
<wli@holomorphy.com>
[PATCH] make memclass() an inline
memclass is too large to be a #define; it overflows 80 columns and does
not make use of facilities available only to macros.
This patch convert memclass() to be an inline function.
<wli@holomorphy.com>
[PATCH] remove antiquated comment
This comment, describing how to optimize for gcc-2.2.2, is so outdated
it should be removed. It's also quite doubtful it should ever have been
placed in this file at all (perhaps something under Documentation/ ?).
This patch removes it.
<wli@holomorphy.com>
[PATCH] remove macros from page_alloc.c
The memlist_* macros serve as nothing but an insulation layer from the
Linux-native generic list operations. This patch removes them in favor
of using generic list operations directly.
<wli@holomorphy.com>
[PATCH] static list init page_alloc.c
inactive_list and active_list are global, yet they are repeatedly
initialized using INIT_LIST_HEAD() in free_area_init_core(). This
patch is originally due to Christoph Hellwig, and by some reports
has been implementated before in 2.4-based trees by Andrea Arcangeli.
<rwhron@earthlink.net>
[PATCH] remove space in cache names
Most /proc/slabinfo cache_names are in the format:
cache_name. There are a couple with spaces in the
name, which is inconsistent and requires a special case
when scripting.
Changes "fasync cache" and "file lock cache" to have
the usual underscore.
<dank@kegel.com>
[PATCH] must be __KERNEL__ for byteorder/generic.h
Here's that patch again (MIME this time, so tabs don't get
lost by my silly gui mailer); applies cleanly against against 2.4.19-pre8.
Nobody commented on it last time I posted it, and it does
make compiling gcc easier, so I guess that makes it trivial patch
monkey fodder. Or am I making a silly mistake?
<zwane@linux.realnet.co.sz>
[PATCH] bluesmoke merge
This patch merges in all the currently outstanding bluesmoke bits from
2.5-dj to 2.5.20, it also has the pleasant side effect of fixing the
compilation. Test compiled with and without MCE.
<pavel@ucw.cz>
[PATCH] Fix suspend-to-RAM in 2.5.20
I created arch/i386/suspend.c not to clash with ACPI people so much in
future. (More stuff is going to move into it in the future, to clean
up functions that really do not belong to the headers.)
<pavel@ucw.cz>
[PATCH] Cleanup swsusp in 2.5.20
This cleans up swsusp in 2.5.20. Killed sysrq-D support (it is too
much trouble to support suspending from interrupt), kill unused
define, fix compile-time warnings (thanks to Adam).
<pavel@suse.cz>
[PATCH] Re: Fix suspend-to-RAM in 2.5.20
Here's followup patch that makes it work. Notice freeze_processes() --
if you don't do that you risk data corruption.
<jsimmons@heisenberg.transvirtual.com>
A few small fixes from porting it over to the new api. ALso a few more drivers from the MIPS platform ported over.
<mochel@osdl.org>
device model udpate:
- make sure drv->devices is initialized on registration (from Peter Osterlund)
- add remove_driver for forcing removal of driver
There was a potential race with the module unload code. When a pci driver was unloaded, it would call pci_unregister_driver, which would simply call put_driver.
If the driver's refcount wasn't 0, it wouldn't unbind it from devices, but the module unload would still continue.
If something tried to access the driver later (since everyone thinks its still there), Bad Things would happen.
This fixes it until there can be tighter integration between the device model and module unload code.
<mochel@osdl.org>
Do manual traversing of drivers' devices list when unbinding the driver.
driver_unbind was called when drv->refcount == 0.
It would call driver_for_each_dev to do the unbinding
The first thing that would do was get_device, which...
BUG()'d if drv->refcount == 0.
Duh.
<mochel@osdl.org>
PCI driver mgmt:
- Make sure proper pci id is passed to probe()
- make sure pci_dev->driver is set and reset on driver registration/unregistration
- call remove_driver to force unload of driver on unregistration
<davem@nuts.ninka.net>
net/core/dev.c: Make handle_diverter return 0
<torvalds@home.transmeta.com>
Fix extra parenthesis in the constant-address rwlock case.
Noted by Alexey Vyskubov
<rmk@arm.linux.org.uk>
[PATCH] fix 2.5.20 ramdisk
2.5.20 seems to be incapable of executing binaries in a ramdisk-based
root filesystem. The ramdisk in question is an ext2fs, with a 1K
block size loaded via the compressed ramdisk loader in do_mounts().
It appears that, in the case of a 1K block sized filesystem, we attempt
to read two 512-byte sectors into a BIO vector. The first one is copied
into the first 512 bytes. The second sector, however, is copied over
the first 512 bytes. Obviously not what we really want.
Rev. 2, slightly cleaned up:
<dalecki@evision-ventures.com>
[PATCH] 2.5.20 IDE 84
- Simplify ide_cmd_type_parse by removing the handling of commands which we
never use.
- Realize that pre_task_out_intr and pre_task_mulout_intr are semanticaly
identical. Use only pre_task_out_intr(). This allowed us to
eliminate the prehandler altogether.
- Updated fix for misconfigured host chips by Vojtech Pavlik.
- Be more permissive about ioctl handling to allow device type drivers to do
they own checks.
- ali14xx cleanups by Andrej Panin.
- Unfold usage ide_cmd_type_parser in tcq.c code. This makes this operation
local to ide-disk.c. Move it as well as the interrupt handlers used only for
the handling of disk requests there too.
- Guard against calling handler before the drive is ready for it in
ata_taskfile()! Well this bug was there before, but right now we inform
about it.
- Unfold ide_cmd_type_praser in ide-disk.c. Merge the remaining bits of it with
get_command. Well it's no more.
- Move recal_intr to ide.c - the only place where it's used.
This doesn't change the "mechanics" of the code but it makes it a lot more
"obvious" what's going on.
<jsimmons@heisenberg.transvirtual.com>
Ported over the TX3912 framebuffer to the new api. Fixed a NODEV error for the Permedia framebuffer driver and patched fbcmap.c to prevent another Oops.
<davem@nuts.ninka.net>
Bonding driver: Merge 2.4.x driver updates into 2.5.
<rml@tech9.net>
[PATCH] remove suser()
Attached patch replaces the lone remaining suser() call with capable()
and then removes suser() itself in a triumphant celebration of the glory
of capable(). Or something. ;-)
Small cleanup of capable() and some comments, too.
<rml@tech9.net>
[PATCH] remove fsuser()
This patch removes fsuser(). Now both suser() and fsuser() are gone and
all permission checks use an appropriate capable() call.
<mochel@osdl.org>
Change unused_initcall to postcore_initcall for things that must be initialized early, but not too early (after the core is done)
<mochel@osdl.org>
s/subsys_initcall/postcore_initcall/ for sys_bys and pci, so they get initialized early enough for arch and subsys initcalls to use them.
<jsimmons@heisenberg.transvirtual.com>
Bug fixes for the fbdev layer.
<rmk@flint.arm.linux.org.uk>
[ARM] Makefile and page.h ARM updates for 2.5.20
<rmk@flint.arm.linux.org.uk>
[ARM] Clean up map_desc structure
- remove LAST_DESC in favour of passing the array size to iotable_init
- replace domain and permission bits/cache attributes with a generic
"type", which can be easily converted to the required domain and
permission bits/cache attributes at run time. It also removes the
possibility for getting such things wrong and (accidentally)
allowing all user space to fiddle with devices directly.
<rmk@flint.arm.linux.org.uk>
[ARM] Cast thread_saved_{pc,fp} to unsigned long.
The kernel expects these to return values in unsigned long types.
<nico@cam.org>
[ARM PATCH] 1166/1: further cleanup of SA1110 suspend/resume code (2.5)
Same thing as patch #1165/1 but for 2.5.x
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Split Makefile into needs / needs not .config
The current top-level Makefile has a fundamental problem which
makes "make oldconfig vmlinux" impossible:
It includes .config, which is changed by "oldconfig". So after "oldconfig"
.config has changed and the .config the Makefile had read is obsolete.
make provides a mechanism to cope with this, it'll restart automatically
if any of the files it included changed, if you let it know that you
changed it, just using a normal rule which has .config as its target.
However, once you tell make that "make oldconfig" changes .config, you
have another problem: oldconfig always uses .config to be remade, there's
no mechanism to tell if it's up to date. So makes notices that .config
has changed, restarts, makes oldconfig again, notices that .config has
changed, restarts, ... you get the picture.
The way to solve this is to do a proper two-stage approach: If you just
say "make oldconfig", there's no need for the Makefile to even read the
.config. If it does not, it won't restart and recurse infintely.
So we divide the Makefile into two sections: One for targets which don't
need the variables from .config, like *config, clean, mrproper and
one section which does the actual build, which needs to know the
CONFIG_ options.
If one of the "noconfig" targets is given, we handle those, without
reading .config. From there, we call make again, filtering out the already
handled targets, to do the main work.
The fact that this actually works correctly can be seen by trying
"make vmlinux oldconfig" which will execute things in the right
order - and this is not just nitpicking, it means that "-j" will
get this case right, too.
The $(CONFIGURATION) hack used to start "make config" automatically
can go away now, too. Since we don't know which of make *config the
user prefers, we'll just ask him call "make whatever-config" himself,
instead of forcing "make config" on him.
<dalecki@evision-ventures.com>
[PATCH] 2.5.20 IDE 85
- Work a bit on the automatic CRC error recovery handling. System still hangs.
But one thing for sure - we don't have to use any specialized irq handler for
it.
- Since ioctl don't any longer submit requests to the queue without
rq->special set, we can safely remove args_error handling from
start_request.
- Make REQ_SPECIAL usage in ide-floppy obvious.
- Use REQ_SPECIAL everywhere instead of REQ_DRIVE_ACB. This is actually a bit
dangerous but should work as far as I can see.
- Unfold the now not REQ_SPECIAL specific dequeing part of ide_end_drive_cmd().
Turns out that we can thereafter remove the calls to ide_end_drice_cmd() at
places where the request type isn't REQ_SPECIAL all any longer. (tcq.c)
- After the above operation it turns out that there are just two places where
ide_end_drive_cmd remains, namely: ata_error, task_no_data_intr
drive_cmd_intr.
We can avoid it by changing the logics in ata_error a slightly.
So now just to cases remain where ide_end_drive_cmd remains used:
drive_cmd_intr and task_no_data_intr.
- Now looking a bit closer we can realize that drive_cmd_intr and
task_no_data_intr can be easly merged together, since the usage of
task_no_data_intr implied taskfile.sector_number == 0.
- Use one single ata_special_intr function for the handling of interrupts
submitted through ide_raw_cmd.
- Move the remaining artefacts of ide_end_drive_cmd directly to
ata_special_intr. Oh we don't need to check for REQ_SPECIAL any longer there,
since the context is already known.
- Set the ata_special_intr handler and command type directly inside
ide_raw_taskfile to save code.

[PATCH] fs/inode.c list_del_init
A few cases of list_del(x) + INIT_LIST_HEAD(x) crept in recently which

[PATCH] fcntl_[sg]etlk() only need the file *
Another simple part of a Matthew Wilcox patch.
We do not need to pass the file descriptor to the fcntl_[sg]etlk

from the file descriptor and verified.

[PATCH] Allow mpage.c to build
When trying to build mpage.c for ARM, I get errors from bio.h since kdev_t
isn't defined. The following fixes this.
(I fail to see how this can build for anyone as it currently stands; its
probably something x86 specific buried in the asm-i386 includes.)
<trini@kernel.crashing.org>
[PATCH] Cleanup i386 <linux/init.h> abuses
The following patch cleans up the i386 usage of <linux/init.h>.
This remove <linux/init.h> from <asm-i386/system.h> which did not need
it, <asm-i386/highmem.h> which only had it due to an extern using
__init, which is not needed.
This adds <linux/init.h> to <asm-i386/bugs.h> which actually has
numerous __init functions and adds <linux/init.h> to 9 files inside of
arch/i386 which were indirectly including <linux/init.h> previously.

kbuild: Fix make -s (silent) and add a quiet mode
Suppress echoing of commands when using "make -s", so that make -s
does indeed have the effect one would expect.
Add a quiet mode, which will print not the entire command but only
one line per rule. To turn it on, use
make KBUILD_VERBOSE=0 vmlinux/whatever
or set KBUILD_VERBOSE=0 in your environment.
For now, the verbose mode is default, which gives you the old behavior
of printing all commands.
The output in quiet mode is based on what Keith Owens' kbuild-2.5 does,
I like, I did not want to invent yet another output format.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Fix 'make some/dir/foo.lst'
Just use 'make some/dir/foo.lst' to produce mixed source code and
assembly for debugging. (If the object gets linked in and you have
a System.map, it'll relocate appropriately)
Apart from the needed Makefile bits, also clean up the script
"makelst".
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Fix calling of scripts
We source some scripts, but still pass parameters to them, e.g.
. mk_version_h $@ $(KERNELRELEASE) $(VERSION) ...
This does not work for all kinds of /bin/sh (it does for bash, that's
why I did not notice).
The fix is easy: Just mark the scripts executable and call instead of
source them.
Unfortunately, patch(1) doesn't understand about propagating chmod.
bk does, so changing the tree isn't hard, and we introduce an explicit
chmod a+x executed during the build for propagating this change into
those trees which get "traditionally" patched up.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Make dependencies at compile time
Making dependencies once up front is not ideal. For one, you don't need
them initially, since when you don't have the .o file, you bet you have
to build it no matter what the dependencies say - dependencies are about
deciding when to *re*build.
There's more reasons, like:
o you don't even know which files you'll build, so you have to go over
all files (even over drivers/{sbus,s390,...} on i386)
o generated files don't exist yet, so you cannot pick up dependencies
on them
o even if dependencies are right initially, they change when you work on
your tree or patch it, and nobody will notice unless you run "make dep"
explicitly again
Anyway, gcc knows hows to emit a correct dependency list, so we just use
that. Well, a little bit of hacking is necessary to remove the dependency
on autoconf.h and put in individual CONFIG_WHAT_EVER dependencies instead,
since otherwise changing one config option would cause everything to be
rebuilt.
I should add that I didn't come up with this all by myself, most work
is actually done in gcc and there were discussions about using -MD on
kbuild-devel way back, so I should mention Keith Owens and Michael
Elizabeth Chastain, and probably others that I forgot, so I apologize
just in case.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Use deep directory structure for include/linux/modules
We used to force the obvious deep structure of all objects which
export symbols into a flat list in include/linux/modules. This
initially caused the restriction the no two exporting objects could
have the same name (Ever wondered why there's ksyms.c and
i386_ksyms.c?)
With the ALSA merge this restriction was mostly lifted by some hack,
but some cases still don't work right (Hi XFS). As it's much cleaner
to just use a normal tree under include/linux/modules, reflecting the
source tree, we now do just that.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Clean up descending into subdirs
Rules.make now has three targets:
o default (a.k.a first_rule): The actual build. Deciding whether
to build built-in or modular or both is decided by
$(KBUILD_MODULES) and $(KBUILD_BUILTIN) now, instead of using
different targets
o fastdep: doesn't actually dependencies anymore, only generates
modversions
o modules_install: Well, you guess what that does.
Cleaned up descending, and no more differentiating between
$(subdir-y) and $(subdir-m). That means $(mod-subdirs) can
go away now.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Really stick with verbose output by default
If KBUILD_VERBOSE is not set in the environment, have it default
to 1 (i.e. on)
<kai@tp1.ruhr-uni-bochum.de>
kbuild: modversions improvements
If an object was changed to not export symbols anymore, the
corresponding stale .ver file would have been left lying around
and been picked up when generating modversions.h.
The obvious solution to remove include/linux/modules/* at the
beginning of "make dep" is not really good, since that means
that .ver files would be regenerated unconditionally, thus causing
a lot of possibly unnecessary rebuilds.
So, instead, we build a temporary shadow tree of all export-objs
(as empty files) during the recursive "make fastdep" phase, and use
that to generate modversions.h.
Ensure that we touch include/linux/modversions.h if any of the
.ver files changes, that's our marker to rebuild all modversions
affected files.

[PATCH] large x86 setup cleanup.
Patrick Mochel did a great job here at splitting up some of the larger
messy parts of arch/i386/kernel/setup.c, and introduced a nice abstraction
which gives us a much nicer way to ensure we can add workarounds for vendor
specific bugs / features without polluting other vendor code paths.
Mark Haverkamp also brought this up to date for merging in my tree circa
2.5.14, and asides from 1-2 now fixed small thinkos, there haven't been
any problems.
This also features a workaround for an errata item on stepping C0 of
the Intel Pentium 4 Xeon, which isn't in your tree yet, where we must
disable the hardware prefetcher to ensure sane operation.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Build modules by default
So here we are: make vmlinux/bzImage/whatever will now also build
modules as it goes. Other than that, everything works as usual.
"make modules" builds only the modules (but you shouldn't need
it anymore). If you don't want the modules built, you can
do "make KBUILD_MODULES= vmlinux/whatever" to only compile built-in
objects.
If people want it, I can also allow for "make vmlinux/whatever nomodules"
to do the same.
Also, add ' ' in Rules.make to properly align output in quiet mode.

USB: emi26.c small fix to enable the driver to build properly
<david-b@pacbell.net>
[PATCH] ohci-hcd, fix urb unlink races
This patch:
- Fixes a longstanding urb unlink race, by switching to a single queue
for EDs being unlinked. The previous two-queue scheme was sensitive to
IRQ latencies: one extra millisecond would make it use the wrong queue.
This updated scheme should handle latencies of up to 32K microseconds
(Cthulu forfend :) and slightly shrinks object code size.
- Related (mostly) cleanup. Some functions and one ED field renamed, ED
layout is a smidgeon more compact (even given more data), driver version
string doesn't reflect CVS, debug message only comes out in verbose mode.
<david-b@pacbell.net>
[PATCH] synchronous control/bulk messaging
This one-liner fixes a problem in synchronous messaging
with usb_bulk_msg(), usb_control_msg(), and everything
that calls usb_control_msg(): you're not allowed to call
blocking functions when you're already on a wait queue.
A better fix would be to just stick the thread on the
wait queue _after_ submitting the URB, but that should
involve more testing than I have time for just now.

<kai@tp1.ruhr-uni-bochum.de>
kbuild: Use a standard "update-if-changed"
For some cases, we cannot decide if a target would change just by looking
at its prequisites, i.e. it's quite likely that it remains the same
even though a prequisite changed. The updated timestamp would cause
a lot of unnecessary recompiles. In this case, we actually generate
a temporary file, compare it to the old file and only the contents
are different do overwrite the old file.
The "update-if-changed" snippet remains always the same, so let's
put it into a macro instead of duplicating it. After that change,
scripts/mkversion_h is so small that we rather put the three remaining
lines directly into the Makefile.
<mochel@osdl.org>
Attempt to better locking in device model core:
- remove device from driver's list on device_detach
- set device's driver to NULL
- decrement reference count on driver on device_detach
- remove devices from driver's list in driver_detach

- don't lock around initialization of device fields
- assume we have a bus in __remove_driver (we enforce this in driver_register)
- do put_bus last in __remove_driver
- lock bus around atomic_set in remove_driver and atomic_dec_and_test in put_driver
- remove from bus's list while we have it locked

kbuild: -DMODULE for assembler source
For consistency, it makes a lot of sense to add -DMODULE (plus
the other special switches with CONFIG_MODVERSIONS) to .S files

(I wouldn't think so, though)

o defconfig
which does the same as make oldconfig but uses the defaults for all

Kernel code should not include userspace headers. To avoid that

which will look into <gcc-path>/include, as proposed by Russell
King.
A similar patch went into 2.4, so not much breakage expected.

So we rename unused_initcall to postcore_initcall and use
this new initcall level for generic BUS object init.

kbuild: Enforce UTS limit, use LANG=C for date/time
Patch by Keith Owens, ported to 2.5.
If the length of $(VERSION).$(PATCHLEVEL).$(SUBLEVEL)$(EXTRAVERSION)
exceeds 64 characters it silently corrupts the utsname data, resulting
in garbage for uname -r and problems running the kernel and modules.
Abort if KERNELRELEASE is too long. Truncation is not good enough, it
results in ambiguous /lib/modules/`uname -r` contents.
Ensure that the date/time in uname are always in LANG=C. Users with
other languages report that 8 bit values cause the boot messages to go
haywire.

kbuild: Add rules for compiling programs on the host
At a couple of places, we need to build programs which run on the
compile host during building the kernel.
Add a new variable "host-progs" to declare such programs. Rules.make will
automatically provide rules to compile these programs with appropriate
command lines etc.
Compared to having explicit rules spread around for doing so, this has
the following advantages:
o shorter
o automatically figures out dependencies and handles changing command
lines
o Nicer output in quiet mode ;-)
Compiling host programs from multiple sources is also possible, analogous
to multi-part objects. E.g. scripts/Makefile has
host-progs := tkparse
tkparse-objs := tkparse.o tkcond.o tkgen.o

[PATCH] fs/locks.c: Only yield once for flocks
This patch removes the annoying and confusing `wait' argument from

had two tasks waiting on a lock, the first one would receive the lock.
Now, the one with the highest priority receives the lock.

A quick summary of the of the added includes:

running. On top of this, the runqueue lock can be dropped in
load_balance and thus we can race and set task->cpu at a very unpleasant
time.
My solution is to just remove the optimization.

[PATCH] matroxfb dies when you try to use secondary head in 2.5.x
James introduced bad bug which causes NULL pointer dereference as soon
as you'll try to use secondary head because of screen_base is not
initialized (it is initialized on wrong head).

[PATCH] missing GET_CPU_IDX in i386 entry.S
resume_kernel uses CPU_IDX but never uses GET_CPU_IDX to get the index.
This is an issue when smp and preemption are both enabled. I also
removed the unused GET_CURRENT_CPU_IDX.

[PATCH] Reduce number of LOOKUP calls in nfs_lookup_revalidate()
fs/nfs/inode.c:
- Ensure that we initialize NFS_MTIME_UPDATE(inode).
- If a directory's mtime changed due to some action on our part
(file creation/deletion/...) don't force a dcache revalidation by
changing NFS_MTIME_UPDATE(inode).
<trond.myklebust@fys.uio.no>
[PATCH] Catch a few more cases where we need to renew inode->d_time
fs/nfs/dir.c:
- Call nfs_renew_times() when we deliberately create a negative dentry.
or rename a file.
