Subject: [PATCH] locking/qspinlock: explicitly include asm/prefetch.h
Date: Sat, 8 Jul 2017 04:56:58 +0900 [thread overview]
Message-ID: <20170707195658.23840-1-shorne@gmail.com> (raw)
In architectures that use qspinlock, like x86, prefetch is loaded
indirectly via the asm/qspinlock.h include. On other architectures, like
OpenRISC, which may want to use asm-generic/qspinlock.h the built will
fail without the asm/prefetch.h include.
Fix this by including directly.
