Rip out our own HMAC-SHA1 and replace with crypto API.  
Can now choose hmac-sha1, hmac-md5, or none with regards to what
HMAC to use for cookie echo verification.

Wanted to try out profiling, so brought up oprofile.  Very 
suprising result of sctp_tsnmap_find_gap_ack() being one of the
hot functions.  This should not be!  Short-circuit by not even 
calling if !has_gap.

Patch submitted by Stephen Rothwell to change 'flags' to
unsigned long and remove 'unused' attribute. 

sctp_packet_bundle_sack() modifies packet->size, but the local copy 
of this value is not updated.  The bug is that we can "put" too much
data to the skb and segfault.  Also, once DATA is in the packet, set
has_sack, so we don't inadvertantly bundle a SACK after DATA.

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]

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).

+ C99 struct initialisers

Another brought forward from 2.4.

A proper PCI_DEVICE_ID... would have been nice,
but for now, this syncs with 2.4
