Together with the change, a new config HAVE_KVM_RESTRICTED_MEM is added
and right now it is selected on X86_64 only.
From the patch implementation, I have no idea why HAVE_KVM_RESTRICTED_MEM is
needed.
The reason is we want KVM further controls the feature enabling. An
opt-in CONFIG_RESTRICTEDMEM can cause problem if user sets that for
unsupported architectures.
HAVE_KVM_RESTRICTED_MEM is not used in this patch. It's better to
introduce it in the patch that actually uses it.
