This series is a v5.15.y only backport (based on v5.15.167) 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.

This series does not apply to earlier stable trees, which will receive a
separate backport.

Mark.
