Move the simple can_do_mlock() check before the full rlimits based
restriction checks for mlock() and mlockall().  As it is, the check
adds nothing.  This has a side-effect of eliminating an unnecessary call
to can_do_mlock() on the munlockall() path.

Calling mlockall(MCL_FUTURE) will erroneously unlock any currently locked

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.

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

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

We can just use skb_shinfo(skb)->tso_{segs,size}
directly.  This also allows us to kill the
hack zone code in ip_output.c

The original impetus for thus change was a problem
noted by John Heffner.  We do not abide by the MSS
of the connection for TCP segmentation, we were using
the path MTU instead.  This broke various local
network setups with TSO enabled and is fixed as a side
effect of these changes.

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.
