Patch from Dave Jiang

This provides support for IXP2xxx error interrupt handling. Previously there was a patch to remove this (although the original stuff was broken). Well, now the error bits are needed again. These are used extensively by the micro-engine drivers according to Deepak and also we will need it for the new EDAC code that Alan Cox is trying to push into the main kernel.

Re-submit of 3072/1, generated against git tree pulled today. AFAICT, this git tree pulled in all the ARM changes that's in arm.diff. Please let me know if there are additional changes. Thx!

ARM processors that have pld instructions are not using those copy_user

Patch from Nicolas Pitre

Using a llx format to print addresses that might possibly be (only) 36
bits wide make sense.  However making it a zero padded 16 char wide
field is a bit excessive and useless.

[ARM] 3083/1: include/asm-arm/arch-ixp4xx/io.h: eliminate warnings for pointer passed to integral function argument

Patch from John Bowler

Fix for a compiler warning, this wasn't apparent in 2.6.12, I
believe the compiler options have been changed (somewhere) so
that passing a (void*) to a (u32) argument is now warned.

This accounts for the majority of the warnings in my builds of
the 2.6.14 kernel for NSLU2.

The patch changes pointer parameters declared as u32 to be
declared as either, for read parameters:

const volatile void __iomem *

and for write parameters:

volatile void __iomem *

Realview was missed in this cleanup...
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

cfq's add_req_fn callback may invoke q->request_fn directly and
depending on low-level driver used and timing, a queued request may be
finished & deallocated before add_req_fn callback returns.  So,
__elv_add_request must not access rq after it's passed to add_req_fn
callback.

This patch moves rq_mergeable test above add_req_fn().  This may
result in q->last_merge pointing to REQ_NOMERGE request if add_req_fn
callback sets it but as RQ_NOMERGE is checked again when blk layer
actually tries to merge requests, this does not cause any problem.
