Merge branch 'sh-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6
* 'sh-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6: dmaengine: shdma: fix a regression: initialise DMA channels for memcpy dmaengine: shdma: Fix up fallout from runtime PM changes. Revert "clocksource: sh_cmt: Runtime PM support" Revert "clocksource: sh_tmu: Runtime PM support" sh: Fix up asm-generic/ptrace.h fallout. sh64: Move from P1SEG to CAC_ADDR for consistent sync. sh64: asm/pgtable.h needs asm/mmu.h sh: asm/tlb.h needs linux/swap.h sh: mark DMA slave ID 0 as invalid sh: Update shmin to reflect PIO dependency. sh: arch/sh/kernel/process_32.c needs linux/prefetch.h. sh: add MMCIF runtime PM support on ecovec sh: switch ap325rxa to dynamically manage the platform camera
