[PATCH 0/2] arm64: Add decode of ISS2 to data abort reports

From: Mark Brown
Date: Tue Apr 18 2023 - 10:08:44 EST


We provide fairly detailed decode of ESR for data aborts but do not
currently cover the information reported in ISS2 which has had quite a
bit of additional information added to it by recent architecture
extensions. Add decode for this information to aid in debugging, for
completeness including features we don't actually use yet.
