locking/atomic, arch/sh: Fix ATOMIC_FETCH_OP()

2016-09-22T12:47:02+00:00

We cannot use the "z" constraint twice, since its a single register
(r0). Change the one not used by movli.l/movco.l to "r".

sh64: failing __get_user() should zero

2016-09-13T21:50:14+00:00

It could be done in exception-handling bits in __get_user_b() et.al.,
but the surgery involved would take more knowledge of sh64 details
than I have or _want_ to have.

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"

sh: add defconfig for J-Core J2

2016-08-05T03:38:22+00:00

This defconfig is intended not to be specific to a particular board;
it enables drivers for all currently-supported hardware, and should be
updated to include additional drivers as they are added.

sh: use common clock framework with device tree boards

2016-08-05T03:29:45+00:00

Enable common clk framework for DT-based boards and disable code that
depends on the legacy sh clk framework when common clk is enabled.
Once legacy drivers are converted over, the old code can be removed
entirely.

sh: Delete unnecessary checks before the function call "mempool_destroy"

2016-08-05T03:29:42+00:00

The mempool_destroy() function tests whether its argument is NULL
and then returns immediately. Thus the test around the calls is not needed.

This issue was detected by using the Coccinelle software.
