Cover letter [PATCH 0/2] ARM64: Fixes for FEAT_E2H0 handling
As the FEAT_E2H0 handling series has made it to -next, some of its shortcomings are becoming apparent:
- A missing ID register in __read_sysreg_by_encoding() is causing CPU hotplug to explode (reported by Marek)
- NV1 is getting advertised on HW that doesn't have FEAT_NV, which is fairly harmless, but still annoying
These fixes should directly apply on the feat_e2h0 branch that Oliver has pushed to kvmarm/next.
