Subject: [PATCH 24/31] arch,score: Convert smp_mb__*
Date: Wed, 19 Mar 2014 07:47:53 +0100 [thread overview]
Message-ID: <20140319065205.060180266@infradead.org> (raw)
In-Reply-To: 20140319064729.660482086@infradead.org
[-- Attachment #1: peterz-score-smp_mb__atomic.patch --]
[-- Type: text/plain, Size: 673 bytes --]
score fully relies on asm-generic/barrier.h, so it can use its default
