Subject: cpumask: remove __first_cpu / __next_cpu
X-Git-Tag: firefly_0821_release~176^2~1917^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e4afa120c98252e44390067c3a6cc775cde30659;p=firefly-linux-kernel-4.4.55.git

cpumask: remove __first_cpu / __next_cpu

They were for use by the deprecated first_cpu() and next_cpu() wrappers,
but sparc used them directly.

They're now replaced by cpumask_first / cpumask_next.  And __next_cpu_nr
is completely obsolete.
