	These CPUs contain the same PMU events (as per the Arm Technical Reference manuals for Cortex A65 and Neoverse E1) This de-duplicates event data, and avoids issues in previous E1 event data (not present in A65 data) * Missing implementation defined events * Inclusion of events that are not implemented: - L1D_CACHE_ALLOCATE - SAMPLE_POP - SAMPLE_FEED - SAMPLE_FILTRATE - SAMPLE_COLLISION Reviewed-by: John Garry <john.garry@huawei.com> Signed-off-by: Nick Forrington <nick.forrington@arm.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: James Clark <james.clark@arm.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Leo Yan <leo.yan@linaro.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Mike Leach <mike.leach@linaro.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Will Deacon <will@kernel.org> Cc: linux-arm-kernel@lists.infradead.org Link: https://lore.kernel.org/r/20220907154932.60808-1-nick.forrington@arm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

	Add PMU events for Arm Neoverse E1 Update mapfile.csv Event data based on: https://github.com/ARM-software/data/tree/master/pmu/neoverse-e1.json which is based on PMU event descriptions from the Arm Neoverse E1 Technical Reference Manual. Mapping data (for mapfile.csv) based on: https://github.com/ARM-software/data/blob/master/cpus.json which is based on Main ID Register (MIDR) information found in the Arm Technical Reference Manuals for individual CPUs.
