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"
