SH7723 is the first hard silicon to implement the L2, and unsurprisingly,
does the precise inverse of what the specification alleges. XOR the
URAM/L2 size bits to get back in line with the existing parsing logic.

The SH-4A series probe we were relying on doesn't work any more on the

Presently with preempt enabled there's the possibility to be preempted
after the TIF_USEDFPU test and the register save, leading to bogus
state post-__switch_to(). Use an explicit preempt_disable()/enable()
pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86
change.

This header is needed on other architectures as well (namely h8300),
which currently fails to build without this in place. Rather than
duplicating the port definition completely there, just move this to a
common location instead.

This should get h8300 working again for 2.6.25, in addition to the
changes already pushed by Sato-san in -rc2.

This patch removes interrupt priority tables from the intc code.
Optimal priority assignment varies with embedded application anyway,
so keeping the interrupt priority tables together with cpu-specific
code doesn't make sense.

The function intc_set_priority() should be used instead to set the
desired interrupt priority level.

The ST40 stuff in-tree hasn't built for some time, and hasn't been
updated for over 3 years. ST maintains their own out-of-tree changes
and rebases occasionally, and that's ultimately where all of the ST40
users go anyways.

In order for the ST40 code to be brought up to date most of the stuff
removed in this changeset would have to be rewritten anyways, so there's
very little benefit in keeping the remnants around either.

This moves off of smp_processor_id() and only sets the probe

This also allows for some header tidying.

This patch removes redundant board specific interrupt code for boards
using sh775x processors and 4 IRQ lines in "Individual Interrupt Mode"
aka IRLM.

Three boards are affected: sh03, snapgear and titan.

The right way to do this is to use cpu specific code provided by intc.
A nice side effect is that sh03 now compiles, board not BROKEN any more.

This patch converts the cpu specific interrupt setup code for sh7760
from ipr + intc2 to intc. New vectors are also added to match the
information provided by the datasheet.

Vectors for IRQ4-IRQ7 are enabled by default. Use plat_irq_setup_pins()
if pins IRL0-3 should be used in IRLM mode.

The patch also adds the SIM block to the serial port platform data.

Slab destructors were no longer supported after Christoph's

BUGs for both slab and slub, and slob never supported them
either.

This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,

This patch reworks the ipr code by grouping the offset array together
with the ipr_data structure in a new data structure called ipr_desc.
This new structure also contains the name of the controller in struct
irq_chip. The idea behind putting struct irq_chip in there is that we
can use offsetof() to locate the base addresses in the irq_chip
callbacks. This strategy has much in common with the recently merged
intc2 code.

One logic change has been made - the original ipr code enabled the
interrupts by default but with this patch they are all disabled by
default.
