[PATCH 4/4] perf vendor events arm64: Reference common and uarch events for A76
From: John Garry
Date: Tue Jan 26 2021 - 00:50:26 EST
Reduce duplication in the JSONs by referencing standard events from
armv8-common-and-microarch.json
In general the "PublicDescription" fields are not modified when somewhat
significantly worded differently than the standard.
Apart from that, description and names for events slightly different to
standard are changed (to standard) for consistency.
