Subject: [PATCH v2, resend 4/6] drivers/base/cpu.c: use __cpu_*_mask directly
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.
