Some host controllers (such as SH7786) have overlapping regions that are
fixed in hardware. The resource allocator does the right thing in
managing this space already, so the conflict case is non-fatal.

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().

Presently the earlytimer probe handles the clockevents driver, which
requires that the clockevents driver be registered first. This bumps it
up by 1 to include the clocksource device, which can be safely ignored
if it doesn't exist, as we will simply error out on that path and defer
to the jiffies clocksource.

These were handled through late_time_init due to kmalloc() and friends
not being available earlier on previously. Now with slab caches being
available much earlier, this is no longer necessary, and we can move the
initialization up to an earlier point. One of the benefits with this is
that printk times are available a bit earlier!

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.

Ftrace on sh handles nop'ing out trace function calls differently than
other architectures. Instead of inserting NOP instructions in place of
the call to the function tracer we branch over the call instructions
and continue executing the main body of the function.

This patch fixes a bug in the implementation of ftrace_modify_code()
where we check that the old value of the code we're about to replace
is an expected one. In the ftrace_make_call() code path
ftrace_modify_code() was comparing the old instruction value with NOP
instructions. The compare was failing because we never actually insert
NOP instructions. It makes sense to just get rid of the NOP
instructions in ftrace_nop and compare the old code with the address
of the function body if we're expecting ftrace to have nop'd out the
function trace call.
