Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k

Pull m68k updates from Geert Uytterhoeven:
 "Summary:
   - Kill harmless warning messages when running a multi-platform kernel
     on Atari
   - Correct virt/phys mixups that didn't actually hurt due to identity
     mappings"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
  m68k/atari: ARAnyM - Always use physical addresses in NatFeat calls
  m68k: Ignore disabled HSYNC interrupt on Atari for irqs_disabled()
