For the two points above, the reason I did that is because later patches call these functions from the newly added arch/arm64/kvm/hyp/nvhe/sys_regs.c. That said, I think that the code that calls them more naturally belongs in arch/arm64/kvm/hyp/nvhe/switch.c instead. I'll fix that, rebase on 5.15-rc2, and respin.
