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()
