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()
