The XTS blockmode uses a copy of the IV which is saved on the stack
and may or may not be properly aligned. If it is not, it will break
hardware cipher like the geode or padlock.
This patch encrypts the IV in place so we don't have to worry about
alignment.

The only board-specific bits that existed here were for setting up the
IRQs, which are now handled by the SH7710 CPU support code instead. As
there's nothing else to do for setup, kill off the board support code

If the radix_tree_preload() fails, we need to destroy the inode we just

wakeups
Idle state is not being detected properly by the xfsaild push code. The
current idle state is detected by an empty list which may never happen
with mostly idle filesystem or one using lazy superblock counters. A
single dirty item in the list that exists beyond the push target can
result repeated looping attempting to push up to the target because it
fails to check if the push target has been acheived or not.
Fix by considering a dirty list with everything past the target as an idle
state and set the timeout appropriately.

Building with CONFIG_DEBUG_SECTION_MISMATCH=y reports:
CC drivers/video/pvr2fb.o
LD drivers/video/built-in.o
WARNING: drivers/video/built-in.o(.text+0xb9b0): Section mismatch in reference from the function pvr2fb_check_var() to the variable .devinit.data:pvr2_fix
The function pvr2fb_check_var() references
the variable __devinitdata pvr2_fix.
This is often because pvr2fb_check_var lacks a __devinitdata
annotation or the annotation of pvr2_fix is wrong.
This is obviously crap as no such reference exists, but it's a bit
closer to reality from older versions which blamed the PCI table. The
real problem was a reference to pvr2_var.vmode from pvr2fb_check_var(),
as pvr2_var is flagged as __devinitdata (pvr2_fix is also, so at least
that part is right).
pvr2_var.vmode is just a fancy way of saying FB_VMODE_NONINTERLACED, so
we just reference that explicitly instead.

Fix locking issues in the pppol2tp driver which can cause a kernel
crash on SMP boxes. There were two problems:-
1. The driver was violating read_lock() and write_lock() scheduling
rules because it wasn't using softirq-safe locks in softirq
contexts. So we now consistently use the _bh variants of the lock
functions.
2. The driver was calling sk_dst_get() in pppol2tp_xmit() which was
taking sk_dst_lock in softirq context. We now call __sk_dst_get().

If an address family is not listed in "Supported Address Types"
parameter(INIT Chunk), but the packet is sent by that family, this
address family should be considered as supported by peer. Otherwise,
an error condition will occur. For instance, if kernel receives an
IPV6 SCTP INIT chunk with "Support Address Types" parameter which
indicates just supporting IPV4 Address family. Kernel will reply an
IPV6 SCTP INIT ACK packet, but the source ipv6 address in ipv6 header
will be vacant. This is not correct.
refer to RFC4460 as following:
IMPLEMENTATION NOTE: If an SCTP endpoint lists in the 'Supported
Address Types' parameter either IPv4 or IPv6, but uses the other
family for sending the packet containing the INIT chunk, or if it
also lists addresses of the other family in the INIT chunk, then
the address family that is not listed in the 'Supported Address
Types' parameter SHOULD also be considered as supported by the
receiver of the INIT chunk. The receiver of the INIT chunk SHOULD
NOT respond with any kind of error indication.
Here is a fix to comply to RFC.

NFS and SELinux worked together previously because SELinux had NFS
specific knowledge built in. This design was approved by both groups
back in 2004 but the recent NFS changes to use nfs_parsed_mount_data and
the usage of nfs_clone_mount_data showed this to be a poor fragile
solution. This patch fixes the NFS functionality regression by making
use of the new LSM interfaces to allow an FS to explicitly set its own
mount options.
The explicit setting of mount options is done in the nfs get_sb
functions which are called before the generic vfs hooks try to set mount
options for filesystems which use text mount data.
This does not currently support NFSv4 as that functionality did not
exist in previous kernels and thus there is no regression. I will be
adding the needed code, which I believe to be the exact same as the v3
code, in nfs4_get_sb for 2.6.26.
