Subject: [PATCH 3/5] drivers/base/cpu.c: use __cpu_*_mask directly
Date: Fri, 25 Sep 2015 20:22:25 +0200 [thread overview]
Message-ID: <1443205347-13634-4-git-send-email-linux@rasmusvillemoes.dk> (raw)
In-Reply-To: <1443205347-13634-1-git-send-email-linux@rasmusvillemoes.dk>
The only user of the lvalue-ness of the cpu_*_mask variables is in
drivers/base/cpu.c, and that is mostly a work-around for the fact that
not even const variables can be used in static initialization. Now
that the underlying struct cpumasks are exposed we can take their
address.
