This series adds Spectre mitigations and errata data for
Qualcomm KRYO2XX Gold (big) and Silver (LITTLE) series of
CPU cores, used for example in MSM8998 and SDM660-series SoCs.

Konrad Dybcio (4):
arm64: Add MIDR value for KRYO2XX gold/silver CPU cores
arm64: kpti: Add KRYO2XX gold/silver CPU cores to kpti safelist
arm64: proton-pack: Add KRYO2XX silver CPUs to spectre-v2 safe-list
arm64: cpu_errata: Apply Erratum 845719 to KRYO2XX Silver

This mostly looks fine to me, but I've added Jeffrey to check the MIDRs
because he's my go-to person for the Qualcomm numbering scheme.

Jeffrey -- please can you check these patches [1], especially the last patch
which has some cryptic revision number in there too?

Jeffrey can confirm this, but the MIDR is right and the cryptic revision
maps to cortex r0p4.

Thanks,
Sai
