Subject: [PATCH v2 0/3] perf vendor events: Support PMU events for A64FX

(I forgot to add Signed-off. Will resend. Sorry about that.)

This patch series supports A64FX PMU event v1.2.

The first patch adds L1 data cache refill prefetch, L2 data cache refill prefetch,
and DCZVA instruction events.

The second patch fixes the lexical definition of event name so that
perf can recognize event name that start with a number.

The third patch adds PMU events for A64FX.

Shunsuke Nakamura (3):
perf vendor events: Add cache refill and DCZVA events
perf tools: Fix lexical definition of event name
perf vendor events: Add Fujitsu A64FX V1.2 pmu event
