ok, this looks like one of the bugs we fixed in the latest x86.git 
(freshly released a few minutes ago). Could you please check x86.git#mm 
with this tip:

  commit cc77c9972685ea84908eff2fe13114160de5d9cb
  Author: Thomas Gleixner <tglx@...utronix.de>

      x86: cpa: rename global_flush_tlb() to cpa_flush_all()

do you still see that crash?
