Merge tag 'sh-for-linus' of git://github.com/pmundt/linux-sh

Pull SuperH updates from Paul Mundt.

The bulk of this is the UAPI disintegration for SH.

* tag 'sh-for-linus' of git://github.com/pmundt/linux-sh:
  sh: Fix up more fallout from pointless ARM __iomem churn.
  sh: Wire up kcmp syscall.
  UAPI: (Scripted) Disintegrate arch/sh/include/asm
