[v2,0/4] kselftest/arm64: Miscelaneous MTE test updates

Message

This series is just a set of minor tweaks and improvements for the MTE
tests that I did while working on the asymmetric mode support for
userspace which seemed like they might be worth keeping even though the
prctl() for asymmetric mode got removed.

v2:
 - Also log PC and fault address on unexpected async faults.
 - Remove redundant system_has_mte variable.

Mark Brown (4):
  kselftest/arm64: Handle more kselftest result codes in MTE helpers
  kselftest/arm64: Log unexpected asynchronous MTE faults
  kselftest/arm64: Refactor parameter checking in mte_switch_mode()
  kselftest/arm64: Add simple test for MTE prctl
