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.

Previous versions can be found at:
v1: https://lore.kernel.org/linuxppc-dev/cover.1594897099.git.sandipan@linux.ibm.com/

Changes in v2:
- Added a wrapper for the gettid syscall based on suggestions
  from Michael and Christophe.

Sandipan Das (6):
  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 wrapper for gettid
  selftests/powerpc: Add test for pkey siginfo verification
