Subject: sh: Kill off pmb slab cache destructor.
This is the last remaining slab destructor in the kernel, which
we kill off and move the resultant list tracking logic up to
the pmb_alloc()/pmb_free() paths.
As Christoph Lameter pointed out, it's potentially unsafe to be
taking the list lock in the destructor anyways, so this is also
more fundamentally correct.
With this in place, we're all set for killing off slab destructors
from the kernel entirely.

Subject: sh: revert addition of page fault notifiers
Just at the time you added them on sh we're removing them from other
architectures. As there's no user yet this patch just removes them
completely. Once you actually have a kprobes patch it should follow
the direct call to kprobes_fault_handler model that powerpc, s390 and
sparc64 employ in 2.6.22-rc1 and that I'm updating other architectures
to.

Subject: sh: sr.bl toggling around idle sleep.
As pointed out by Saito-san, without the sr.bl manipulation we can
occasionally hit delays in the idle loop due to interrupt handling, so
ensure that interrupts are blocked before going to sleep.
At the same time, we throw in TIF_POLLING_NRFLAG for the !hlt_counter
case (primarily used by the ST-40 parts).

Subject: sh: Wire up kdump crash kernel exec in die().
Now that we have the basic kdump support in place, add it in to
die() so we can enter the crash kernel automatically.

Subject: sh: Fix dreamcast build for IRQ changes.
When the irq.h changes went in, the dreamcast code was still
referencing an old value. Switch it back to the IRQ number,
which fixes this:

arch/sh/boards/dreamcast/irq.c:59: error: `OFFCHIP_IRQ_BASE' undeclared (first
use in this function)
arch/sh/boards/dreamcast/irq.c:59: error: (Each undeclared identifier is reported only once
arch/sh/boards/dreamcast/irq.c:59: error: for each function it appears in.)
