Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k
Pull m68k fixes from Geert Uytterhoeven:
"Here are a few fixes for the m68k architecture. Nothing fancy this
time, just a build fix for the asm/system.h disintegration, and two
fixes for missing platform checks (one got in during last merge
window), which can cause crashes in multi-platform kernels."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
m68k/q40: Add missing platform check before registering platform devices
m68k/mac: Add missing platform check before registering platform devices
m68k: include asm/cmpxchg.h in our m68k atomic.h
