#     Merge tag 'powerpc-5.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
#     
#     Pull powerpc fixes from Michael Ellerman:
#      "An assortment of fixes that were either missed by me, or didn't arrive
#       quite in time for the first v5.4 pull.
#     
#        - Most notable is a fix for an issue with tlbie (broadcast TLB
#          invalidation) on Power9, when using the Radix MMU. The tlbie can
#          race with an mtpid (move to PID register, essentially MMU context
#          switch) on another thread of the core, which can cause stores to
#          continue to go to a page after it's unmapped.
#     
#        - A fix in our KVM code to add a missing barrier, the lack of which
#          has been observed to cause missed IPIs and subsequently stuck CPUs
#          in the host.
#     
#        - A change to the way we initialise PCR (Processor Compatibility
#          Register) to make it forward compatible with future CPUs.
#     
#        - On some older PowerVM systems our H_BLOCK_REMOVE support could
#          oops, fix it to detect such systems and fallback to the old
#          invalidation method.
#     
#        - A fix for an oops seen on some machines when using KASAN on 32-bit.
#     
#        - A handful of other minor fixes, and two new selftests.
#     
#       Thanks to: Alistair Popple, Aneesh Kumar K.V, Christophe Leroy,
#       Gustavo Romero, Joel Stanley, Jordan Niethe, Laurent Dufour, Michael
#       Roth, Oliver O'Halloran"
