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
