Merge branch 'sh-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git...

* 'sh-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6:
  sh: se/7724: Remove FSI/B of GPIO init code
  sh: se/7724: Update clock framework of FSI clock to non-legacy
  sh: Assume new page cache pages have dirty dcache lines.
  sh: boards: mach-se: use IS_ERR() instead of NULL check
  sh: Add div6_reparent_clks to clock framework for FSI
  dma: shdma: add a MODULE_ALIAS() to allow module autoloading
