    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"
