Rather than hardcoded names in modprobe, modules can offer their own
aliases (which can be overridden by the config file).

Here are the tty-ldisc ones.

In mips, outw_p() is a #define do...while(0) which, in the case of ?:,
results in a statement being used where an expression is required.

Please delete Documentation/kmod.txt: it's entirely outdated and misleading.

I thought about rewriting it, but there's not much to add beyond what's in
the CONFIG_KMOD's help text.

The same address `i8042_request_irq_cookie' is used in three places for the
i8042 request_irq() argument.  This means that if someone calls
i8042_check_mux() or i8042_check_aux() while the IRQ is in use, the
free_irq() call in there will free the wrong IRQ handler.

So give all three instances of request_irq() in i8042.c a distinct address by
which to identify the IRQ instance.

(This is probably a non-bug, because the `check' functions are not called
when the device is open, but it is better this way).

Create the pty slaves on init so the behaviour is consistant with 2.4 and 2.6
without devfs.

From: James Morris <jmorris@redhat.com>

This patch adds an 'selinux' boot parameter which must be used to actually
enable SELinux.

It follows some internal discussion about deployment issues, where a vendor
would want to ship a single kernel image with SELinux built-in, without
requiring the user to use it.

Without specifying selinux=1 as a boot parameter, SELinux will not register
with LSM and selinuxfs will not be registered as a filesystem.  This causes
SELinux to be bypassed entirely from then on, and no performance overhead
is imposed.  Other security modules may then also be loaded if needed.

The routine disk_round_stats showed up considerably under oprofile for high
disk io load (four processes doing dd to the same disk (different
partitions) on a 4 way).

This is because the counter in_flight which is per-cpu right now gets read
every time disk_round_stats gets called.  Per cpu counters like disk
statistics improve write speed, but reads are slow (since all cpus' local
counter values have to be read and summed up).  Considering the fact that
in_flight counter is modified post disk_round_stats (which reads the
in_flight counter) it is better not to per-cpu this counter.

Following patch does just that.  Below is the profile comparison before and
after the change.  This was on a 4 way PIII Xeon, 1G ram, 2.6.0-test4-mm2.

From: Mitchell Blank Jr <mitch@sfgoth.com>

This patch makes the following improvements to might_sleep():

 o Add a "might_sleep_if()" macro for when we might sleep only if some
   condition is met.  It's a bit tidier, and has an unlikely() in it.

 o Add might_sleep checks to skb_share_check() and skb_unshare() which
   sometimes need to allocate memory.

 o Make all architectures call might_sleep() in both down() and
   down_interruptible().  Before only ppc, ppc64, and i386 did this check.
   (sh did the check on down() but not down_interruptible())

Add checks for kfree() of a page which was allocated with __alloc_pages(),
and for free_pages() of a page which was allocated with kmalloc().

This fixes a bug in deadline and AS that causes insert_here to be ignored on
blk_fs_requests. This has been causing problems with SCSI requeueing code.
It makes elevator insertion more correct as advertised wrt insert_here and
REQ_SOFTBARRIER.

It also fixes a buglet in the as_requeue code where the request wasn't being
put into the front of the list (in rare cases).

Add a config option which allows ioport/mmio selection for QLA1280 SCSI
driver.

With this patch applied QLA1280 can be used on Visws again.

The new HPET RTC emulation code uses a function in rtc.c, get_rtc_time().

So that function was made non-static.  Problem is, the same function name is
used elsewhere by some architectures, so there will be linkage problems.

And rtc_get_time() is used too, so I renamed it to rtc_get_rtc_time().

Also, the HPET code was setting CONFIG_HPET_EMULATE_RTC by hand in a header
file.  Fix it to use the Kconfig system properly.

Anton needs this for ppc64.  Things overflow with a huge number of CPUs.

From: Neil Brown <neilb@cse.unsw.edu.au>

With the current code in bio_add_page, if fail_segments is ever set, it
stays set, so bio_add_page will eventually fail having recounted the
segmentation once.

I don't think this is intended.  This patch changes the code to allow
success if the recounting the segments helps.

This removes include/asm-arm/proc-armv entirely, merging the
contents into the relevant include files in include/asm-arm.
We also update various files in arch/arm which reference
definitions in the now non-existent directory.

Remove more of the redundant 26-bit ARM CPU support from the
32-bit ARM tree.

Here is the first part of ISDN bugfixes for 2.6.
It should make ISDN work again with most controllers.

More fixes follow after more testing.

The enclosed patch tries to clean the tulip de4x5 driver, and update
it to some of the 2.6 APIs :

- Use PCI and EISA probing APIs
- Use generic DMA API
- Fix DE425 init on the Jensen
- Remove de4x5 from Space.c

It's been tested on x86 and Alpha, with a DE425 (21040, EISA), a DE435
(21040, PCI) and a quad DLink (4*21143, PCI).

The major problem with this patch is that, because of the Space.c
removal, interfaces get potentially renumbered. This has been
discussed to death on lkml, without any obvious solution. IMHO, we'd
better remove as many drivers as we can from Space.c before
2.6.0-final ships...

forced into double negatives.

the compilation of cosa.c was already fixed in your BK tree, so we can
now remove the dependency on BROKEN.

This fixes the build of the via-pmu.c driver when CONFIG_PMAC_PBOOK is
not set.

From Benjamin Herrenschmidt <benh@kernel.crashing.org>:

This adds the Kconfig option for the PowerMac IDE driver "LED" feature
(using the laptop's front LED as a disk activity indicator).  It also
adds a small bit to ide-probe.c that was missing from Jens patch when he
added the activity function infrastructure.  He did add the hwif field,
but not the code to actually enable it.

From Daniela Engert <dani@ngrt.de>.

It was disabled to workaround a bug in a driver.  The orginal bug was
