#     Merge tag 'powerpc-5.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
#     
#     Pull powerpc fixes from Michael Ellerman:
#      "One fix to prevent runtime allocation of 16GB pages when running in a
#       VM (as opposed to bare metal), because it doesn't work.
#     
#       A small fix to our recently added KCOV support to exempt some more
#       code from being instrumented.
#     
#       Plus a few minor build fixes, a small dead code removal and a
#       defconfig update.
#     
#       Thanks to: Alexey Kardashevskiy, Aneesh Kumar K.V, Christophe Leroy,
#       Jason Yan, Joel Stanley, Mahesh Salgaonkar, Mathieu Malaterre"
