Merge branch 'for-4.15-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
Pull percpu fix from Tejun Heo:
"Just one patch to work around CRIS boot problem caused by a recent
change which freed a temporary boot data structure. The root cause is
on CRIS side but it doesn't seem trivial to fix. For now, work around
by skipping freeing on CRIS"
