Patch from Nicolas Pitre

This requires the definition of PLD added to assembler.h in
patch #1363/1.

Patch from Nicolas Pitre

This should replace patch #1441/1.

This is about 20% faster than the original code, and a few percent faster 
than previous patch.

Tried to add plds to the clear_user_page but it was of no benefit.

Patch from Nicolas Pitre

This improves on what I did with patch #1362/1 by adding preloads for 
architectures that support it.  On an XScale PXA255 this provides a 20% 
performance gain.

Tested with all combinations of sizes and alignments.

- don't report PCI aborts during config cycles as errors.
- don't scan the pci buses if we receive a master abort.
- setup error handlers earlier.

Fix potential oops if kmalloc returns NULL.
Really return an error when out of memory.

This cset updates cyber2000fb (used on NetWinders) to the new
fbcon API, and adds cfbfillrect, cfbcopyarea and cfbimgblt
objects when building cyber2000fb.

The ARM do_div() implementation was rather lax in that it only
performed a 32-bit divide.  This cset fixes this oversight by
providing a 64-bit by 32-bit division in asm.

This is necessary for posix-timers to function correctly.

Fix more annoying compile problems due to wrong types
for comparing jiffies. This patch applies to alpha arch.

From Thomas Weyergraf.

- Check for parent PCI bus instead of bridge device to break the
  look in common_swizzle(). Functionally it's the same, but it's
  cleaner for PC-style host bridges (nautiluses).
- Generic PCI setup changes finally went in (thanks to rmk), so that
  FIXME in common_init_pci() can go.

It's possible to squeeze more bits out of lower half of pte,
but 32 seem to be a plenty...

This is needed as we are still not using the driver core model for
matching up devices to drivers, but doing it by hand.  Once that is
changed, this will not be needed.

Still pretty ugly debug macro, but this at least
makes it do the right thing when used in if/else blocks

Fix from Joe Perches <joe@perches.com>

This patch adds selectable EdgeTriggered/LevelTriggered behaviour to
epoll.

It has been widely discussed on lkml about two weeks ago and everyone
very welcome the change.  It has been even more widely discussed through
private emails with application developers, that do not feel confortable
posting on lkml.  The great value of the patch is that selecting the LT
behaviour, applications using poll/select can be ported very easily to
epoll, making existing apps to benefit from epoll scalability with very
short ETA's.

The API remains the same with the addition of a EPOLLET event flag that
sets the LT/ET behaviour for that fd.

Many usb drivers use the usb_devfs_handle variable instead of just
adding the usb/ prefix directly to their devfs_register calls.  Fix
that and make usb_devfs_handle static and unexported.

.. by moving a bunch of devfs-related code from fs/partition/check.c
to fs/devfs/base.c.  Also has the nice sideffect of getting rid of
a bunch of ugly ifdefs.

[This is the new and improved, rediffed, applying and compilable
 version.  In short it's perfect]

From: Nikita Danilov, Maneesh Soni

d_lookup() is forgetting to release the lock when the rename race happens.

by having a cast followed by an initializer. It seems even gcc can't
do it right anyway in some versions (as reported by Jens Axboe).
