ioctl_by_bdev() passes in a NULL file*, so we had better not dereference it.

put_page_testzero() does BUG_ON(page_count(page)) when its argument is p.

To handle sparse physical APIC ID's properly the phys_cpu_present_map must
be scanned beyond bit NR_CPUS while ensuring no more than NR_CPUS are woken
in order not to attempt to wake non-addressible cpus.

The following patch adds that logic to smp_boot_cpus() and corrects the
failure to wake secondaries reported by dhowells, with successful wakeup,
runtime, reboot, and halting reported after it was applied.

When I grepped for these variables I failed to notice the references in
acpi/wakeup.S.  This patch fixes this.

A couple of new PCI IDs which were found in 3com's driver by Xose Vazquez
Perez <xose@wanadoo.es>.

We don't know if these work, but if they are really 905B's and 920's it
should be OK.

Various performance critical sections.

The increased cache footprint may be a pessimisation, especially on earlier
CPUs where unlikely() doesn't do anything useful, and we fall back to
trusting gcc to DTRT.

Fix some places which were doing

	memcpy(to, from, sizeof(to));
and
	memset(to, 0, sizeof(to));

Found by the Stanford checker.

This is a really old patch from the IA64 tree and as Cirrus Logic doesn't
maintain the driver anymore for about two years now no one picked it up..

From: David Mosberger <davidm@napali.hpl.hp.com>

Don't truncate the ioremap return value to 32-bits.

Attached are two patches that make bttv compile and work in 2.5.69-mm6.  I
think this broke in -mm4.

From: Gerd Knorr <kraxel@bytesex.org>

Yet another big one (due to not being updated for a long time) -- saa7134
driver update.  Changes:

 * various bugfixes / cleanups.

 * new cards added to the cardlist.

 * started support for saa7133/35 chips.

 * make the driver check pci quirks.

From: Gerd Knorr <kraxel@bytesex.org>

This patch updates the tv card tuner module.  It adds support for a new tuner
and has some minor fixes + cleanups.  Also deletes some dead code.

From: Gerd Knorr <kraxel@bytesex.org>

This patch updates a number of video4linux-related i2c modules.  There are a
number of bugfixes which accumulated over time, also some no-op i2c changes
due to merging the i2c cleanups back into my tree and tweak them to make the
modules compile on both 2.5.x and 2.4.x.

From: Gerd Knorr <kraxel@bytesex.org>

This patch updates the bttv documentation.

From: Gerd Knorr <kraxel@bytesex.org>

This patch updates the v4l1-compat module.  Changes:

 * use f_op->poll() instead of do_select()

 * reduce stack usage of the v4l1_translate_ioctl() function.

 * misc minor fixes here and there.

From: Gerd Knorr <kraxel@bytesex.org>

This minor patch updates the video-buf module.  It just adds a export
for the videobuf_next_field function and adds some debug printk's.

The vmtruncate() function shifts down by PAGE_CACHE_SHIFT, then calls
vmtruncate_list(), which deals in terms of PAGE_SHIFT instead.  Currently,
no harm done, since PAGE_CACHE_SHIFT and PAGE_SHIFT are identical.  Some
day they might not be, hence this patch.

I also took the liberty of modifying a hand-coded "if" that seems to
optimize for files that are not mapped to instead use unlikely().

Here is a patch to fix CONFIG_APM=m in 2.5.69-bk11.  My patch to have APM
restore the systenter MSRs failed to handle the modular case, which fails
with unresolved symbols.

Since suspend.o is used from both APM (module or built-in) and ACPI sleep
(built-in), I made suspend.o built-in and dependent on CONFIG_PM.

From: Oleg Drokin <green@namesys.com>

With the current 'one block at a time' algorithm, writes past the end of a
file are slow because each new file block is separately added into the tree
causing shifting of other items which is CPU expensive.

With this new implementation if you write into file with big enough chunks,
it uses half as much CPU.  Also this version is more SMP friendly than the
current one.

There are some known-bad applications that break with this patch (ie.  start
to work very slow or even hang).

This is because the filesystem returns a large value in the stat.st_blocksize
hint (128k instead of 4k).  This tickles a small number of application bugs.
One is KDE's kmail 3.04 (fixed by upgrading to 3.1+) and the other is
sleepycat's database from before 1997.

If you hit a slowdown problem that you believe is related to the increased
"recommended i/o size" value, try to mount your fs with nolargeio=1 mount
option (remount should work too).

This patch exports block_commit_write(), generic_osync_inode() and
remove_suid() to modules.

I've had these reiserfs patches in -mm for many months.  We've been
undecided because they trigger bugs in a couple of apps.  But those apps
are now fixed, so it's best to get these speedups in.


From: Oleg Drokin <green@namesys.com>

This patch allows insertion of more than one "indirect" block pointer into
the tree in reiserfs.  (with all the necessary balancing code changes).
The first user of that feature is hole-creation code that is now ~1000
times more cpu-efficient for the case of large holes.

Apparently boomerang_interrupt() is generating lots of "nobody cared"
warnings - one per packet it seems.  Frankly, I don't have a clue why.

These are ancient cards and the driver is otherwise stable, so just
change it to return IRQ_HANDLED and move on...

From: William Lee Irwin III <wli@holomorphy.com>

I was just looking over this and noticed 2.4.x makes u64 dma_addr_t
conditional on CONFIG_HIGHMEM64G where 2.5.x uses CONFIG_HIGHMEM.  It's
clearly not necessary on CONFIG_HIGHMEM4G, hence this obvious patch.

 - generic_file_open() comment fix (Bill Irwin)

 - kerneldoc fix in truncate.c (Aniruddha M Marathe)

 - remove truncate debug check.

 - page_lock comment fix (Robert Love)

 - remove unused device mapper label.

 - 3c509 docco fix ("Mark Tranchant" <mark@tranchant.freeserve.co.uk>)

Fix an accidentally negated comparison.

Change the defn of cpu_callout_map for voyager to volatile to match other
stuff.

Add cpu_mask_to_apicid to generic arch to fit with Keith's changes.

From: john stultz <johnstul@us.ibm.com>

This patch fixes a circular dependency (a function in mach_apic.h requires
hard_smp_processor_id() and hard_smp_processor_id() requires macros from
mach_apic.h) that has been in the subarch code for a bit, but was hacked
around with some #ifdefs.

With the inclusion of the generic-subarch the hack was dropped and bigsmp
and summit promptly broke.  So this makes things compile again.

It is incorrectly precalculating the string's length.

Also move ft6_dflt_pointer to .bss and use void
in ip6_dst_gc as it doesn't take any paramenters

Thanks to Andrew Morton for reporting.
