Subject: cpumask: remove bitmap_scnprintf_len and cpumask_scnprintf_len
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f4ed0deae8983591264d0e194e168ef65f4775f5;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

cpumask: remove bitmap_scnprintf_len and cpumask_scnprintf_len

They aren't used.  They were briefly used as part of some other patches to
provide an alternative format for displaying some /proc and /sys cpumasks.
They probably should have been removed when those other patches were dropped,
in favor of a different solution.
