Merge branch 'sh-latest' of git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6

* 'sh-latest' of git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6:
  sh: include Migo-R TS driver in Migo-R defconfig
  sh: correct definitions to access stack pointers
  sh: Tidy up SH-4A unaligned load support.
  dma: shdma: NMI support.
  sh: mach-sdk7786: Handle baseboard NMI source selection.
  sh: mach-rsk: Add polled GPIO buttons support for RSK+7203.
  sh: Break out cpuinfo_op procfs bits.
  sh: Enable optional gpiolib for all CPUs with pinmux tables.
  sh: migrate SH_CLK_MD to mode pin API.
  sh: machvec IO death.
