Applied to arm64 (for-next/cpufeature), thanks!
[1/1] arm64/cpufeature: Validate hypervisor capabilities during CPU hotplug https://git.kernel.org/arm64/c/c73433fc630c
But please note that I made some changes to verify_hyp_capabilities() so that it's (a) static and (b) uses IS_ENABLED to avoid the dummy function definition. I also extended the IS_ENABLED_check so that it doesn't conflict with the KVM kconfig changes from Fuad. Please shout if you think I'm still missing something.
Cheers, -- Will
