Subject: [PATCH 092/342] wait.h: include atomic.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=c5650d84f71a6e552239a8cb37bfd4c4f71c3694

This pops up on ARM. Non-RT gets its atomic.h include from spinlock.h
