Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu
Pull m68knommu fixes from Greg Ungerer:
"Just a small collection of cleanups and fixes this time, no big
changes. The most interresting are to make the m68k and m68knommu
consistently use CONFIG_IOMAP, clean out some unused board config
options and flush the cache on signal stack creation"
* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu:
m68k: remove 16 unused boards in Kconfig.machine
m68k: define 'VM_DATA_DEFAULT_FLAGS' no matter whether has 'NOMMU' or not
m68knommu: user generic iomap to support ioread*/iowrite*
m68k/coldfire: flush cache when creating the signal stack frame
m68knommu: Mark functions only called from setup_arch() __init
