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

* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/mfleming/sh-2.6:
  sh: Use correct mask when comparing PMB DATA array values
  sh: Do not try merging two 128MB PMB mappings
  sh: Fix zImage load address when CONFIG_32BIT=y
  sh: Fix address to decompress at when CONFIG_32BIT=y
  sh: Assembly friendly __pa and __va definitions
