This patch contains two corrections to the LSM-IPsec Nethooks patches
previously applied.
(1) free a security context on a failed insert via xfrm_user
interface in xfrm_add_policy. Memory leak.
(2) change the authorization of the allocation of a security context
in a xfrm_policy or xfrm_state from both relabelfrom and relabelto
to setcontext.

It looks like the bridge netfilter code does not correctly update
the hardware checksum after popping off the VLAN header.
This is by inspection, I have *not* tested this.
To test you would need to set up a filtering bridge with vlans
and a device the does hardware receive checksum (skge, or sungem)

When a user-space server application calls bind on a socket, then in kernel
space this bound socket is considered 'x25-linked' and the SOCK_ZAPPED flag
is unset.(As in x25_bind()/af_x25.c).
Now when a user-space client application attempts to connect to the server
on the listening socket, if the kernel accepts this in-coming call, then it
returns a new socket to userland and attempts to reply to the caller.
The reply/x25_sendmsg() will fail, because the new socket created on
call-accept has its SOCK_ZAPPED flag set by x25_make_new().
(sock_init_data() called by x25_alloc_socket() called by x25_make_new()
sets the flag to SOCK_ZAPPED)).
Fix: Using the sock_copy_flag() routine available in sock.h fixes this.
Tested on 32 and 64 bit kernels with x25 over tcp.

Update IDE to use new blk_ordered. This change makes the
following behavior changes.
* Partial completion of the barrier request is handled as
failure of the whole ordered sequence. No more partial
completion for barrier requests.
* Any failure of pre or post flush request results in failure
of the whole ordered sequence.
So, successfully completed ordered sequence guarantees that
all requests prior to the barrier made to physical medium and,
then, the while barrier request made to the physical medium.

add @uptodate argument to end_that_request_last() and @error
to rq_end_io_fn(). there's no generic way to pass error code
to request completion function, making generic error handling
of non-fs request difficult (rq->errors is driver-specific and
each driver uses it differently). this patch adds @uptodate
to end_that_request_last() and @error to rq_end_io_fn().
for fs requests, this doesn't really matter, so just using the
same uptodate argument used in the last call to
end_that_request_first() should suffice. imho, this can also
help the generic command-carrying request jens is working on.

Unlike other ioscheds, as-iosched handles alias by chaing them using
rq->queuelist. As aliased requests are very rare in the first place,
this complicates merge/dispatch handling without meaningful
performance improvement. This patch updates as-iosched to dump
aliased requests into dispatch queue as other ioscheds do.

This was harmless, but for the case of a device that had no irq

This patch adds suspend patch to libata, and ata_piix in particular. For
most low level drivers, they should just need to add the 4 hooks to
work. As I can only test ata_piix, I didn't enable it for more
though.
Suspend support is the single most important feature on a notebook, and
most new notebooks have sata drives. It's quite embarrassing that we
_still_ do not support this. Right now, it's perfectly possible to
suspend the drive in mid-transfer.

The code to overwrite/reread for addressing read errors in raid1/raid10
currently assumes that the read will not alter the buffer which could be used
to write to the next device. This is not a safe assumption to make.
So we split the loops into a overwrite loop and a separate re-read loop, so
that the writing is complete before reading is attempted.

md supports multiple different RAID level, each being implemented by a
'personality' (which is often in a separate module).
These personalities have fairly artificial 'numbers'. The numbers
are use to:
1- provide an index into an array where the various personalities
are recorded
2- identify the module (via an alias) which implements are particular
personality.
Neither of these uses really justify the existence of personality numbers.
The array can be replaced by a linked list which is searched (array lookup
only happens very rarely). Module identification can be done using an alias
based on level rather than 'personality' number.
The current 'raid5' modules support two level (4 and 5) but only one
personality. This slight awkwardness (which was handled in the mapping from
level to personality) can be better handled by allowing raid5 to register 2
personalities.
With this change in place, the core md module does not need to have an
exhaustive list of all possible personalities, so other personalities can be
added independently.
This patch also moves the check for chunksize being non-zero into the ->run
routines for the personalities that need it, rather than having it in core-md.
This has a side effect of allowing 'faulty' and 'linear' not to have a
chunk-size set.
