[PATCH 4.19 0/3] arm64: errata: Expand speculative SSBS workaround once more

Posted by Mark Rutland 1 month, 3 weeks ago

This series is a v4.19 only backport (based on v4.19.322) of the recent
MIDR updates for the speculative SSBS workaround, which were originally
posted at:

  https://lore.kernel.org/linux-arm-kernel/20240930111705.3352047-1-mark.rutland@arm.com/

... and were originally merged upstream in v6.12-rc2.

The Cortex-A715 cputype definitions (which were originally merged
upstream in v6.2) are backported as a prerequisite.

Mark.
