Hello,
I would like to request
2a355ec25729 ("arm64: kpti: Whitelist Cortex-A CPUs that don't implement the CSV3 field")
to be backported to 4.19 stable.
These CPUs are not susceptible to Meltdown, so enabling the mitigations
for Meltdown (kpti) should be redundant, especially since we know that
it can have a huge performance penalty for certain workloads.
kpti will still be automatically enabled if KASLR is enabled.
Kind regards,
Niklas
