Hyper-V provides a para-virtualization hypercall
HvFlushGuestPhysicalAddressSpace
to flush nested VM address space mapping in l1 hypervisor and it's to reduce
overhead
of flushing ept tlb among vcpus. The tradition way is to send IPIs to all
affected
vcpus and executes INVEPT on each vcpus. It w
The struct hv_vp_assist_page was defined incorrectly.
The "vtl_control" should be u64[3], "nested_enlightenments_control"
should be a u64 and there is 7 reserved bytes following "enlighten_vmentry".
This patch is to fix it.
