Patch from Catalin Marinas

On ARM926EJ-S, the "always assume write" for Jazelle data aborts
causes Java code exit with segmentation fault every time it tries
to access a read-only page. This patch puts some restrictions on what 
can be done in the Jazelle state but it allows it to run.

We recently changed the VSID allocation on PPC64 to use a new scheme
based on a multiplicative hash.  It turns out our choice of multiplier
(the largest 28-bit prime) wasn't so great: with large contiguous
mappings, we can get very poor hash scattering.  In particular earlier
machines (without 16M pages) which had a reasonable about of RAM (>2G
or so) wouldn't boot, because the linear mapping overflowed some hash
buckets.

This patch changes the multiplier to something which seems to work
better (it is, rather arbitrarily, the median of the primes between
2^27 and 2^28).  Some more theory should almost certainly go into the
choice of this constant, to avoid more pathological cases.  But for
now, this choice fixes a serious bug, and seems to do at least as well
at scattering as the old choice on a handful of simple testcases.

fix a problem in pfm_check_task_state() and pfm_task_incompatible()
which was caused by the introduction of the new TASK_TRACED state.
Tool would fail to attach to a process,i.e., PFM_LOAD_CONTEXT would
fail. With the fix perfmon now accepts to operate on tasks which are

Patch from Ian Campbell

The include of asm/arch/pxa-regs.h has been removed from
asm-arm/arch-pxa/hardware.h and now needs to be included
from the relevant files. 

I have verified the fixes to arch/arm/mach-pxa/sleep.S and 
drivers/char/watchdog/sa1100_wdt.c myself. My local tree
has other changes to include/asm-arm/arch-pxa/serial.h
but I beleive that the attached is necessary and correct.

Some dual use type errors still exist, where the
bios mapping is type-confused.

A few one-liners removed hundreds of lines of warnings.
The driver was clean, just not using the proper types.

It was almost correct, apart from some silly details.

The x86 ROM probing is still wrong, and doesn't use the proper
PCI MMIO accessor functions. Sparse (correctly) warns about
it.

Remove absolutely tons of totally unnecessary casts,
once the types are done right in the first place.

The driver is still ugly as hell and needs some serious
indentation fixing, but this makes it not spew hundreds
of warnings any more.

Only recently digitized for our edification.

Basic cleanup - replace untyped/wrongly typed "dev->base_addr" with
use of a strongly typed "ioaddr".

Fixed up resulting mii_delay() search-and-replace error noticed by
Andrey Klochko.

Played a bit with overcommit the past hour.

Am not entirely satisfied with the no overcommit mode 2 -
programs segfault when the system is close to that boundary.
So, instead of the somewhat larger patch that I planned to send,
just symbolic names for the modes.

I didn't have ISDN builds on in my tree for some reason hence missing these
two from the tidy ups at the end. Marcel Holtmann also came up with the
same fixes although I didnt find that email until I did these.

If we read and write the PROM chips at the same time, as might happen at boot
when salinfo extracts MCA records and a user is checking the PROM revision
in /proc/sgi_prominfo, an MCA might occur, since the PROM chips can't be
accessed that way.  This patch fixes the problem for systems with new PROMs
(>= 3.50) by using the SAL to do PROM reads.
