38b0e42aba [SCTP]: Fix sctp_assoc_seq_show() panics on big-endian systems.
This patch corrects the panic by casting the argument to the
pointer of correct size.  On big-endian systems we ended up loading
only 32 bits of data because we are treating the pointer as an int*.
By treating this pointer as loff_t*, we'll load the full 64 bits
and then let regular integer demotion take place which will give us
the correct value.

49392e5ecf [SCTP]: sctp doesn't show all associations/endpoints in /proc
When creating a very large number of associations (and endpoints),
/proc/assocs and /proc/eps will not show all of them.  As a result
netstat will not show all of the either.  This is particularly evident
when creating 1000+ associations (or endpoints).  As an example with
1500 tcp style associations over loopback, netstat showed 1420 on my
system instead of 3000.

The reason for this is that the seq_operations start method is invoked
multiple times bacause of the amount of data that is provided.  The
start method always increments the position parameter and since we use
the position as the hash bucket id, we end up skipping hash buckets.

This patch corrects this situation and get's rid of the silly hash-1
decrement.

9834a2bb49 [SCTP]: Fix sctp_cookie alignment in the packet.
On 64 bit architectures, sctp_cookie sent as part of INIT-ACK is not
aligned on a 64 bit boundry and thus causes unaligned access exceptions.

The layout of the cookie prameter is this:
|<----- Parameter Header --------------------|<--- Cookie DATA --------
-----------------------------------------------------------------------
| param type (16 bits) | param len (16 bits) | sig [32 bytes] | cookie..
-----------------------------------------------------------------------

The cookie data portion contains 64 bit values on 64 bit architechtures
(timeval) that fall on a 32 bit alignment boundry when used as part of
the on-wire format, but align correctly when used in internal
structures.  This patch explicitely pads the on-wire format so that
it is properly aligned.

7a48f923b8 [SCTP]: Fix potential race condition between sctp_close() and sctp_rcv().
Do not release the reference to association/endpoint if an incoming skb is
added to backlog. Instead release it after the chunk is processed in
sctp_backlog_rcv().

2ddb55f091 [PATCH] x86_64: Fix VSMP build
Patch fixes a build problem with CONFIG_X86_VSMP.  The vSMP bits probably

gathered some fuzz on its way to mainline, and safe_halt() which was outside
the #endif (CONFIG_X86_VSMP) somehow got inside the !CONFIG_X86_VSMP condition,
hence being undefined and breaking CONFIG_X86_VSMP builds.  Patch takes
safe_halt() and halt() macros out of the #endif

8817210d4d [PATCH] x86_64: Flexmap for 32bit and randomized mappings for 64bit
Another try at this.

For 32bit follow the 32bit implementation from Ingo -
mappings are growing down from the end of stack now
and vary randomly by 1GB.

Randomized mappings for 64bit just vary the normal mmap break
by 1TB. I didn't bother implementing full flex mmap for 64bit
because it shouldn't be needed there.

one is set, the other must be marked 'undefined'.  This wasn't being done

Result: if md1 is a raid1, it is stopped and a raid5 is created there, it
might still appear to be a raid1.

095da6cbb6 [PATCH] fuse: fix bitfield race
Fix race in setting bitfields of fuse_conn.  Spotted by Andrew Morton.

The two fields ->connected and ->mounted were always changed with the
fuse_lock held.  But other bitfields in the same structure were changed
without the lock.  In theory this could lead to losing the assignment of
even the ones under lock.  The chosen solution is to change these two
fields to be a full unsigned type.  The other bitfields aren't "important"
enough to warrant the extra complexity of full locking or changing them to
bitops.

For all bitfields document why they are safe wrt. concurrent
assignments.

Also make the initialization of the 'num_waiting' atomic counter explicit.
