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" * 'for-4.15-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: percpu: hack to let the CRIS architecture to boot until they clean up
