[RESEND PATCH stable 4.14 4.19 0/2] Backport "KVM: arm64: Filter out invalid core registers IDs in KVM_GET_REG_LIST"

Hi stable maintainers,

This is a backport patch for commit df205b5c6328 ("KVM: arm64: Filter out invalid core register IDs in KVM_GET_REG_LIST") to 4.14 and 4.19. This commit was not applied to the 4.14-stable tree due to merge conflict [1]. To backport this, commit be25bbb392fa ("KVM: arm64: Factor out core register ID enumeration") that has no functional changes is cherry-picked.

I'd appreciate if if you could consider backporting this to 4.14 and 4.19.

Best regards, Takahiro
