Merge tag 'powerpc-5.8-8' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc...

Pull powerpc fix from Michael Ellerman:
 "Fix a bug introduced by the changes we made to lockless page table
  walking this cycle.

  When using the hash MMU, and perf with callchain recording, we can
  deadlock if the PMI interrupts a hash fault, and the callchain
  recording then takes a hash fault on the same page.

  Thanks to Nicholas Piggin, Aneesh Kumar K.V, Anton Blanchard, and
  Athira Rajeev"
