#     Merge tag 'powerpc-5.1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
#     
#     Pull powerpc fixes from Michael Ellerman:
#      "One fix for a boot failure on 32-bit, introduced during the merge
#       window.
#     
#       A fix for our handling of CLOCK_MONOTONIC in the 64-bit VDSO. Changing
#       the wall clock across the Y2038 boundary could cause CLOCK_MONOTONIC
#       to jump forward and backward.
#     
#       Our spectre_v2 reporting was a bit confusing due to a bug I
#       introduced. On some systems it was reporting that the count cache was
#       disabled and also that we were flushing the count cache on context
#       switch. Only the former is true, and given that the count cache is
#       disabled it doesn't make any sense to flush it. No one reported it, so
#       presumably the presence of any mitigation is all people check for.
#     
#       Finally a small build fix for zsmalloc on 32-bit.
#     
#       Thanks to: Ben Hutchings, Christophe Leroy, Diana Craciun, Guenter
#       Roeck, Michael Neuling"
