Subject: [PATCH 1/4] perf vendor events arm64: Remove L1D_CACHE_LMISS from AmpereOne list

amperene/cache.json file tried to include L1D_CACHE_LMISS while it
doesn't exist in common-and-microarch.json. While this bug doesn't seem to
cause issue in newer kernels with jevents.py script, it prevents building
older perf tools with the backported patch.

Fixes: a9650b7f6fc0 ("perf vendor events arm64: Add AmpereOne core PMU events")
Reported-by: Dave Kleikamp <dave.kleikamp@...cle.com>
Closes: https://lore.kernel.org/all/76bb2e47-ce44-76ae-838e-53279047084d@oracle.com/
