As the vcpu hotplug and virtio-mem support on arm64 is on the road, we can pick them up as experimental and enable it in kata on arm64.
to enable vcpu hotplug, we need change on serval parts:

enable vcpu hotplug in guest kernel PR_3281
enable vcpu hotplug in qemu PR_3292
don't pass thread and socket info to qemu daemon in kata PR_3281
adjust kernel and qemu build script
add docs about how to use this feature in kata

jongwu added feature needs-review labels

          config: remove 2 config as they are removed in 5.15

17de3a5

I'm sure that it is correct to remove CONFIG_ARM64_UAO and
CONFIG_MANDATORY_FILE_LOCKING and . Both are gone in 5.15. Maintain a
specific config files for a kernel version is a little ugly. If someone
needs them, shout at me.
