Subject: [PATCH 5.4-6.17 0/2] arm64: errata: Apply workarounds for Neoverse-V3AE

Hi All,

This series is a backport intended for all supported stable kernels (5.4-6.17)
of the recent errata workarounds for Neoverse-V3AE, which were originally posted
at:

  https://lore.kernel.org/all/20250919145832.4035534-1-ryan.roberts@arm.com/

... and were originally merged upstream in v6.18-rc1.

I've tested that these patches apply to 5.4-6.12 without issue, but there is a
trivial conflict to resolve in silicon-errata.rst for it to apply to 6.16 and
6.17. Are you happy to deal with that or should I send a separate series?

Thanks,
Ryan
