When arch/sh/include/asm/syscall_32.h is included from a file that
doesn't also include linux/err.h the following error is produced,

'sh/platform-updates' and 'sh/perf_counter'

This enables support for the generic software-based perf counters.
Hardware counter support could be added in the future, but the lack
of a performance counter IRQ makes this rather dubious.

Convert most arches to use asm-generic/kmap_types.h.
Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h,
controlled by __WITH_KM_FENCE from each arch's kmap_types.h file.
Would be nice to be able to add custom KM_types per arch, but I don't yet
see a nice, clean way to do that.
Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and
68k(tonyb).
Note: avr32 should be able to remove KM_PTE2 (since it's not used) and
then just use the generic kmap_types.h file. Get avr32 maintainer
approval.

The irqsoff tracer uses the atomic_* functions internally, but the
implementations of those functions in arch/sh/include/asm/atomic-irq.h
disable irqs to achieve atomicity. A continuous loop ensues where we
disable interrupts, trace the interrupt disabling, call atomic_*
functions, disable interrupts, trace the interrupt disabling, etc..
The simplest solution to all this is to just convert uses of
local_irq_save()/local_irq_restore() the raw_* equivalents because the
raw_* equivalents don't call trace_hardirqs_on()/trace_hardirqs_off().

We're weaning the core code off handing cpumask's around on-stack.
This introduces arch_send_call_function_ipi_mask(), and by defining

The current asm-generic/page.h only contains the get_order
function, and asm-generic/uaccess.h only implements
unaligned accesses. This renames the file to getorder.h
and uaccess-unaligned.h to make room for new page.h
and uaccess.h file that will be usable by all simple
(e.g. nommu) architectures.

This provides a reliable way for asm-generic/types.h and other
files to find out if it is running on a 32 or 64 bit platform.
We cannot use CONFIG_64BIT for this in headers that are included
from user space because CONFIG symbols are not available there.
We also cannot do it inside of asm/types.h because some headers
need the word size but cannot include types.h.
The solution is to introduce a new header <asm/bitsperlong.h>
that defines both __BITS_PER_LONG for user space and
BITS_PER_LONG for usage in the kernel. The asm-generic
version falls back to 32 bit unless the architecture overrides
it, which I did for all 64 bit platforms.

The existing asm-generic versions are incomplete and included
by some architectures. New architectures should be able
to use a generic version, so rename the existing files and
change all users, which lets us add the new files.

This fixes up a typo in the ll/sc based cmpxchg code which apparently
wasn't getting a lot of testing due to the swapped old/new pair. With
that fixed up, the ll/sc code also starts using it and provides its own

This patch fixes the 16-bit case of the sh4a specific

the 16-bit version of sh4a get_unaligned() results in
