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" * tag 'powerpc-5.8-8' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/64s/hash: Fix hash_preload running with interrupts enabled
