[PATCH v2 0/6] 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.

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.
