KVM doesn't fully support Hyper-V reenlightenment notifications on
migration. In particular, it doesn't support emulating TSC frequency
of the source host by trapping all TSC accesses so unless TSC scaling
is supported on the destination host and KVM_SET_TSC_KHZ succeeded, it
is unsafe to proceed with migration.
Vitaly Kuznetsov (3):
i386: Make Hyper-V related sections KVM only
i386: Fix 'hypercall_hypercall' typo
i386: Make sure kvm_arch_set_tsc_khz() succeeds on migration when
'hv-reenlightenment' was exposed
