Fixes the build error caused by -Werror on gcc 3.x compilers:
arch/sh/kernel/signal_32.c: In function `sys_sigaction':

Currently the wdt forces HZ=1000 and sidesteps CONFIG_HZ completely. This
is a remnant from when HZ was hardcoded and before CONFIG_HZ was
introduced. Additionally, not all of the timers have this requirement
these days, so it's also an artificial limitation. Just kill it off and
use CONFIG_HZ directly.

This adds in the L1I/L1D/L2 cache shape support to their respective
entries in the ELF auxvt, based on the Alpha implementation. We use
this on the userspace libc side for calculating a tightly packed
SHMLBA amongst other things.

When a get_user(to, from++) is called the pointer increment is performed
after its first usage, in the specific after the __add_ok invokation.
This causes a wrong get_user return value, putting a wrong character
in the destination variable. This patch solves the problem using a new
temporary pointer.
Additionally this reworks the use of the register banks, allowing for
consolidation between the MMU and nommu implementations.

Presently most of the 29-bit physical parts do P1/P2 segmentation
with a 1:1 cached/uncached mapping, jumping between the two to
control the caching behaviour. This provides the basic infrastructure
to maintain this behaviour on 32-bit physical parts that don't map
P1/P2 at all, using a shiny new linker section and corresponding
fixmap entry.

This implements kernel-level atomic rollback built on top of gUSA,
as an alternative non-IRQ based atomicity method. This is generally
a faster method for platforms that are lacking the LL/SC pairs that
SH-4A and later use, and is only supportable on legacy cores.

With all of the different CPU types this was getting a but unwieldly.
Since sh64 is now integrated, we don't have to worry about multiple
architectures caring about the header definitions.
Split out the defs for each asm/cpu/ to make rtc-sh slightly less
visually offensive.

Avoid namespace collision with a CCR1 definition. The general
SH code always expects CCR anyways, so there's no point in keeping
the CCR1 naming around.
Fixes up synclink collisions:

This adds support for the SH7263 (SH-2A) CPU.
This particular CPU is a superset of SH7203, adding some additional
peripheral blocks and hooking up additional (reserved on SH7203)
vectors in the INTC block.
No visibly nasty surprises, yet..
