Merge tag 'powerpc-5.5-3' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc...

Pull powerpc fixes from Michael Ellerman:
 "One fix for a regression introduced by our recent rework of cache
  flushing on memory hotunplug.

  Like several other arches, our VDSO clock_getres() needed a fix to
  match the semantics of posix_get_hrtimer_res().

  A fix for a boot crash on Power9 LPARs using PCI LSI interrupts.

  A commit disabling use of the trace_imc PMU (not the core PMU) on
  Power9 systems, because it can lead to checkstops, until a workaround
  is developed.

  A handful of other minor fixes.

  Thanks to: Aneesh Kumar K.V, Anju T Sudhakar, Ard Biesheuvel,
  Christophe Leroy, Cédric Le Goater, Madhavan Srinivasan, Vincenzo
  Frascino"
