Merge tag 'powerpc-5.0-3' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:
 "A couple of weeks of fixes.

  There's one fix for an oops on Power9 machines with Open CAPI
  adapters.

  And a fix for probable memory corruption in some of the new NPU code,
  caught by smatch though and not seen in the wild.

  Plus a few other minor fixes.

  There's one non-fix which is the perf_regs change. That was sent
  during the merge window but I accidentally only merged the first of
  two patches in the series. It's been in linux-next so hopefully
  doesn't conflict with anything in acme's tree.

  Thanks to: Alexey Kardashevskiy, Andrew Donnellan, Breno Leitao,
  Christian Lamparter, Christophe Leroy, Dan Carpenter, Frederic Barrat,
  Greg Kurz, Jason A. Donenfeld, Madhavan Srinivasan"
