Subject: cpumask: resurrect CPU_MASK_CPU0
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1527781d228cd88af6c2f78c13a9cb43b3f69f30;p=deliverable%2Flinux.git

cpumask: resurrect CPU_MASK_CPU0

We removed it in 2f0f267ea072 (cpumask: remove deprecated functions.),
but grep shows it still used by MIPS, and not unreasonably.
