[GIT PULL] arch/sh updates for 4.8

[Rich Felker]

Hi Linus,

Please pull these changes for arch/sh. They're based off a commit in
your current tree to resolve conflicts with 726328d92a
(locking/spinlock, arch: Update and fix spin_unlock_wait()
implementations). 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.

Rich

  sh: add device tree source for J2 FPGA on Mimas v2 board (2016-08-05 03:38:26 +0000)

----------------------------------------------------------------
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.

----------------------------------------------------------------
Markus Elfring (1):
      sh: Delete unnecessary checks before the function call "mempool_destroy"

Pan Xinhui (1):
      sh: cmpxchg: fix a bit shift bug in big_endian os

Paul Gortmaker (4):
      sh: make time.c explicitly non-modular
      sh: make mm/asids-debugfs explicitly non-modular
      sh: make board-secureedge5410 explicitly non-modular
      sh: make heartbeat driver explicitly non-modular

Rich Felker (16):
      sh: add support for linking a builtin device tree blob in the kernel
      sh: make sigcontext definition consistent across fpu/nofpu models
      sh: disable aliased page logic on NOMMU models
      sh: fix futex/robust_list on nommu models
      sh: allow clocksource drivers to register sched_clock backends
      sh: fix build regression with CONFIG_OF && !CONFIG_OF_FLATTREE
      sh: add support for J-Core J2 processor
      sh: add AT_HWCAP flag for J-Core cas.l instruction
      sh: add J2 atomics using the cas.l instruction
      sh: add working futex atomic ops on userspace addresses for smp
      sh: SMP support for SH2 entry.S
      sh: add SMP support for J2
      sh: do not perform IPI-based cache flush except on boards that need it
      sh: use common clock framework with device tree boards
      sh: add defconfig for J-Core J2
      sh: add device tree source for J2 FPGA on Mimas v2 board
