2ff9f317f1 sh: Tidy up some of the cpu legacy dma header mess. 
This has turned in to quite a mess, and with CPUs that care using
dmaengine now it's about time to start cleaning up after the legacy DMA
code. For starters, kill off the stubs for the CPUs that don't do
anything, as well as all of the unused definitions. This leaves us with a
set of IRQs and base addresses we can deal with later.

0c6012313c sh: Move sh4a dma header from cpu-sh4 to cpu-sh4a. 
cpu-sh4a headers take priority over cpu-sh4 ones by virtue of the build
system, there's no need to try and mingle sh4a stuff in cpu-sh4.

16ee6576e2 Merge remote-tracking branch 'tip/perf/urgent' into perf/core 
Merge reason: We are going to queue up a dependent patch:

"perf tools: Move parse event automated tests to separated object"

That depends on:

commit e7c72d8
perf tools: Add 'G' and 'H' modifiers to event parsing

Conflicts:
	tools/perf/builtin-stat.c

Conflicted with the recent 'perf_target' patches when checking the
result of perf_evsel open routines to see if a retry is needed to cope
with older kernels where the exclude guest/host perf_event_attr bits
were not used.

c3e0af9879 Revert "sh: Ensure fixmap and store queue space can co-exist." 
This reverts commit 20e7c297ef.
With store queues enabled the area above P4SEG has special properties
from the MMU's point of view, which was causing fixmap failure. We'll
have to do something else to satisfy the vmalloc range check.

Historical prepare_to_copy() is mostly a no-op, duplicated for majority of

register state like fpu there.

Remove it and use the arch_dup_task_struct() instead.
