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.rutla...
... 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.
