2012-05-19sh: Tidy up some of the cpu legacy dma header mess.Paul Mundt
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.

2012-05-19sh: Move sh4a dma header from cpu-sh4 to cpu-sh4a.Paul Mundt
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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-18Merge remote-tracking branch 'tip/perf/urgent' into perf/coreArnaldo Carvalho de Melo
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.

2012-05-18sh64: Fix up vmalloc fault range check.Paul Mundt
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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-18Revert "sh: Ensure fixmap and store queue space can co-exist."Paul Mundt
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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2012-05-16fork: move the real prepare_to_copy() users to arch_dup_task_struct()Suresh Siddha
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.
