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
