Merge tag 'tag-sh-for-4.6' of git://git.libc.org/linux-sh
Pull arch/sh updates from Rich Felker:
"This includes minor cleanups, a fix for a crash that likely affects
all sh models with MMU, and introduction of a framework for boards
described by device tree, which sets the stage for future J2 support"
* tag 'tag-sh-for-4.6' of git://git.libc.org/linux-sh:
sched/preempt, sh: kmap_coherent relies on disabled preemption
sh: add SMP method selection to device tree pseudo-board
sh: add device tree support and generic board using device tree
sh: remove arch-specific localtimer and use generic one
sh: make MMU-specific SMP code conditional on CONFIG_MMU
sh: provide unified syscall trap compatible with all SH models
sh: New gcc support
sh: Disable trace for kernel uncompressing.
sh: Use generic clkdev.h header
