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.

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.

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.

With the previous attempt reverted this switches to conditionalizing the
end address. Nominally VMALLOC_END, but extended for P3_ADDR_MAX in the
store queue case.

This reverts commit 20e7c297efeca0861adcca073a0d283da659834b.
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.

This migrates SH7786 to evt2irq() backed hwirq lookup rather than
using an open-coded calculation. This will make it possible to reposition

The generic hardirq layer provides all of the routines that we need these
days, so we don't require any of the dynamic IRQ API wrapping, and can
call in to irq_alloc_descs() directly.

Historical prepare_to_copy() is mostly a no-op, duplicated for majority of
the architectures and the rest following the x86 model of flushing the extended
register state like fpu there.
Remove it and use the arch_dup_task_struct() instead.
