Leonid Yegoshin 6f6ed48265 MIPS: Replace smp_mb with release barrier function in unlocks. ... Repleace smp_mb() in arch_write_unlock() and __clear_bit_unlock() to smp_mb__before_llsc() call which does "release" barrier functionality. It seems like it was missed in commit f252ffd50c during introduction of "acquire" and "release" semantics. [ralf@linux-mips: The original patch submission was labelled a fix but actually it replaces a barrier with another less restrictive type of barrier so it doesn't fix any ill behaviour but rather squeezes out a tad better performance. Further improvments will be possible once smp_release() has been merged.] Signed-off-by: Leonid Yegoshin <Leonid.Yegoshin@imgtec.com> Cc: linux-mips@linux-mips.org Cc: benh@kernel.crashing.org Cc: will.deacon@arm.com Cc: linux-kernel@vger.kernel.org Cc: markos.chandras@imgtec.com Cc: macro@linux-mips.org Cc: Steven.Hill@imgtec.com Cc: alexander.h.duyck@redhat.com Cc: davem@davemloft.net Patchwork: https://patchwork.linux-mips.org/patch/10507/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>		2015-06-21 21:54:30 +02:00
