1. Add local_df field to struct sk_buff to mark packets which
   are to be fragmented locally despite of their IPv6ness of IP DF flag
2. Add ext2_header_len to tcp_opt to keep memory of part of header length
   depending on route
3. Add trailer_len to struct dst_entry and xfrm_state to know how
   much of space should be reserved at tail of frame for subsequent
   transformations.
4. [BUG] icv_trun_len must be used while mss claculation, not
   icv_full_length.

1. Fix illegal dereference of potentially freed memory in xfrm_policy.c
2. Complete wildcard flow addresses to real ones in xfrm_lookup().
3. Respect optional flag when chacking for input policy.
4. Delete orphaned comments in ip.h.
5. Fix mistakedly freed route in tcp connect.

1. Fix bad reservation in xfrm_state_check_space()
2. Macroize formula for reservation, use the macro over all the places
   in IP.

Patch from Bob Miller <rem@osdl.org>

The get_disk() function should check the return value from kobject_get()
before passing it to to_disk().  This patch fixes this error.

(Acked by Pat)

Patch from Andreas Gruenbacher <agruen@suse.de>

In both 2.5 and 2.4, the fs/nfsd/vfs.c:nfsd_symlink() function calls down to
notify_change().  If notify_change fails for some reason, the error code is
not converted to an nfs no-the-wire error code as is should.  The attached
patches fix that (one for 2.4, the other for 2.5).

Patch from Martin J. Bligh and Dave Hansen

People with ordinary PCs are accidentally turning on NUMA support, and people
with NUMA machines are finding the NUMA option mysteriously disappearing.
This patch sets the defaults to sane things for everyone, and only allows you
to turn on NUMA with both SMP and 64Gb support on (it's useful for the
distros on non-Summit boxes, but not on their UP kernels ;-)).

I've also moved it below the highmem options, as it logically depends on
them, so this makes more sense.  For those searching for NUMA support on
*real* NUMA machine, Dave has provided some guiding comments to show them
what they messed up (it's totally non-obvious).  Hopefully this will stop
people's recent unfortunate foot-wounds (I think UP machines were defaulting
to NUMA on ...  oops).

This makes sysrq facilities available to remote users.

Writing a 'C' to /proc/sysrq-trigger receives the same treatment as typing
sysrq-C on the local keyboard.

Patch from Dave Hansen <haveblue@us.ibm.com>

Adds some commentary to these newly-introduced macros.

Patch from John Levon <levon@movementarian.org>

wli got an oops from this. The callbacks call mod_timer so the timer had
better be setup by then

Patch from "Martin J. Bligh" <mbligh@aracnet.com>

This removes the DO_ACTION stuff.  The downside is that we add some boring
and repetive code.  The upside is that it's simple, and mere mortals can read
it without screwing their brains into a small piece of silly putty and
bouncing it off the wall.  I think that's more important than pure source
code size.

Patch from "Randy.Dunlap" <rddunlap@osdl.org>

Adds an oops counter to the oops messages, such as:

	Oops: 0002 [#2]

So we can tell whether oops reports refer to the first oops, or to some
less-interesting followon oops.

Patch from george anzinger <george@mvista.com>

Fix the "large sleep returns EINVAL" problem, and clean a few things up.

Patch from Oleg Drokin <green@namesys.com>

    There is trivial memleak on error exit path in
    fs/ufs/util.c::_ubh_bread_()

Patch from Oleg Drokin <green@namesys.com>

   There is trivial memleak on error exit path in nfs get_sb function.

Patch from Christoph Hellwig <hch@lst.de>

It extends the maximum amount of memory which may be kmalloced on nommu
machines.  This is needed because these machines cannot perform vmalloc().

We couldn't really find a way of doing this which avoided the ifdef tangle.

Patch from Christoph Hellwig <hch@lst.de>

This is from the uClinux patches - there are a few more stubs needed
in nommu.c to get the mmuless plattforms working.

Patch from "Randy.Dunlap" <randy.dunlap@verizon.net>

This patch (to 2.5.64) reduces the stack usage in vt_ioctl()
from 0x334 bytes to 0xec bytes (P4, UP, gcc 2.96).

- optimise file_kill() to not take the global lock if the file is not on a
  list.

- Use optimised file_kill() in a few places rather than open-coding the
  list removal.

- Remove the private freelist.  There's no point in special-casing file
  structure allocations in this way.

- Hence the freeing of files can be moved outside file_list_lock()

- Replace euid test with capable(CAP_SYS_ADMIN).

- Tidy various other things up.

Replace the odd handling of f_list.next = NULL with list_emptiness.

release_mem() is altering the file->f_list lists without taking the
appropriate spinlock.

Patch from Manfred Spraul <manfred@colorfullife.com>

Fixes the lock contention over file_list_lock by simply removing the unneeded
anon_list.  So filp allocation does not need to take a global lock any more.

The use of a spinlock to protect files_stat.nr_files is a bit awkward, but
the alternative is a custom sysctl handler, and isn't much more efficient
anyway.

Patch from Andi Kleen <ak@muc.de>

copy_thread could leak memory if you had a io bitmap and passed wrong
arguments to the new clone flags.

Patch from Robert Love <rml@tech9.net>

There are a couple uses of 'p->state=foo' in mm/ which are open coded.
This patch converts them to the proper [__]set_current_state() function.

Patch from Robert Love <rml@tech9.net>

This patch is by Inaky Perez-Gonzalez.

There are a couple uses of 'p->state=foo' in fs/ which are open coded.
This patch converts them to the proper [__]set_current_state() function.
