Subject: [PATCH 0/4] Add support for ARMv8.3-SPE

The ARMv8.3-SPE adds an Alignment Flag in the Events packet and filtering
on this event using PMSEVFR_EL1, together with support for the profiling
of Scalable Vector Extension operations.

Patch 1: Update the kernel driver, mainly for PMSEVFR_EL1.

Patch 2: Update the decode process of Events packet and Operation Type
  packet in perf tool.

Patch 3-4: Synthesize unaligned address access events and partial/empty
  predicated SVE events, also add two itrace options for filtering.

Wei Li (4):
  drivers/perf: Add support for ARMv8.3-SPE
  perf: arm-spe: Add support for ARMv8.3-SPE
  perf auxtrace: Add new itrace options for ARMv8.3-SPE
  perf: arm-spe: Synthesize new events for ARMv8.3-SPE
