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