linux-next: Fixes tag needs some work in the powerpc tree

Hi all,

In commit

  3b6c3adbb2fa ("powerpc/perf: Exclude pmc5/6 from the irrelevant PMU group constraints")

Fixes tag

  Fixes: 7ffd948 ("powerpc/perf: factor out power8 pmu functions")

has these problem(s):

  - SHA1 should be at least 12 digits long
    Can be fixed by setting core.abbrev to 12 (or more) or (for git v2.11
    or later) just making sure it is not set (or set to "auto").

Since Michael doesn't generally rebase his tree, this is more to be
remebered for next time.
