[PATCH 0/5] Improvements to pkey tests

[Sandipan Das]

Based on recent bugs found in the pkey infrastructure, this
improves the test for execute-disabled pkeys and adds a new
test for detecting inconsistencies with the pkey reported by
the signal information upon getting a fault.

Sandipan Das (5):
  selftests/powerpc: Move pkey helpers to headers
  selftests/powerpc: Add pkey helpers for rights
  selftests/powerpc: Harden test for execute-disabled pkeys
  selftests/powerpc: Add helper to exit on failure
  selftests/powerpc: Add test for pkey siginfo verification
