Did you run core-pkey and ptrace-pkey?

The pkey selftests that are in tools/testing/selftests/powerpc/ptrace ?

Because those are failing for me:

  test: core_pkey
  tags: git_version:c899d94
  [FAIL] Test FAILED on line 245
  [Core Read (Running)]          AMR: 3fcfffffffffffff IAMR: 1105555555555555 UAMOR: 33cfffffffffffff
  failure: core_pkey
  
  test: ptrace_pkey
  tags: git_version:c899d94
  [FAIL] Test FAILED on line 214
  [Ptrace Read (Running)]        AMR: 3fcfffffffffffff IAMR: 1105555555555555 UAMOR: 33cfffffffffffff
  [User Write (Running)]         AMR: 3fffffffffffffff pkey1: 3 pkey2: 4 pkey3: 5
  failure: ptrace_pkey


Some of which is presumably test case bugs, but there's at least one
kernel bug with the UAMOR handling.

So this series will have to wait until next week :/
