Merge tag 'sh-for-4.8' of git://git.libc.org/linux-sh

Pull arch/sh updates from Rich Felker:
 "These changes improve device tree support (including builtin DTB), add
  support for the J-Core J2 processor, an open source synthesizable
  reimplementation of the SH-2 ISA, resolve a longstanding sigcontext
  ABI mismatch issue, and fix various bugs including nommu-specific
  issues and minor regressions introduced in 4.6.

  The J-Core arch support is included here but to be usable it needs
  drivers that are waiting on approval/inclusion from their subsystem
  maintainers"
