Description snipped from Steven Rostedt's PPC patch:
When idle is called, interrupts are blocked, but the idle
function will still wake up on an interrupt. The problem is
that the interrupt disabled latency tracer will take this call
to idle as a latency.
This patch disables the latency tracing when going into idle.

This was removed in the libgcc integration, but there are still some
compilers that need this. We also relax the rules on the ISA tuning in
the cases where there are no matches for the CPU tuning and adopt the
-any default, which matches the intent of the isa-y target list. This
compensates for mismatches where binutils supports a wide array of
targets whilst the compiler is much more restricted.

This adds support for unaligned loads on SH-4A, using the SH-4A's
neutered movua.l instruction. As movua.l is r0-inspired, stores are
still handled through the packed struct.

This patch adds a pass-through case when ioremapping P4 addresses.
Addresses passed to ioremap() should be physical addresses, so the
best option is usually to convert the virtual address to a physical
address before calling ioremap. This will give you a virtual address
in P2 which matches the physical address and this works well for
most internal hardware blocks on the SuperH architecture.
However, some hardware blocks must be accessed through P4. Converting
the P4 address to a physical and then back to a P2 does not work. One
example of this is the sh7722 TMU block, it must be accessed through P4.
Without this patch P4 addresses will be mapped using PTEs which
requires the page allocator to be up and running.
