Applied to arm64 (for-next/fixes), thanks! [1/1] arm64: Add missing sentinel to erratum_1463225 https://git.kernel.org/arm64/c/09c717c92b52 Cheers,

When the erratum_1463225 array was introduced a sentinel at the end was missing thus causing a KASAN: global-out-of-bounds in is_affected_midr_range_list on arm64 error.
