Merge master.kernel.org:/pub/scm/linux/kernel/git/lethal/sh-2.6.23
* master.kernel.org:/pub/scm/linux/kernel/git/lethal/sh-2.6.23: sh: Fix fs.h removal from mm.h regressions. sh: fix get_wchan() for SH kernels without framepointers sh: arch/sh/boot - fix shell usage rtc: rtc-sh: Correct sh_rtc_set_time() for some SH-3 parts. sh: remove support for sh7300 and solution engine 7300 sh: Add sh to the CC_OPTIMIZE_FOR_SIZE dependencies. sh: Kill off virt_to_bus()/bus_to_virt(). sh: sh-sci - fix SH7708 support sh: Restrict DSP support to specific CPUs. sh: Silence sq compile warning on sh4 nommu. sh: Kill the rest of the SE73180 cruft. sh: remove support for sh73180 and solution engine 73180 sh: remove old broken pint code sh: Reclaim beginning of P3 space for vmalloc area. sh: Fix Dreamcast DMA issues. sh: Add kmap_coherent()/kunmap_coherent() interface for SH-4.
