KVM: SVM: hyper-v: Direct Virtual Flush support
From Hyper-V TLFS:
"The hypervisor exposes hypercalls (HvFlushVirtualAddressSpace,
HvFlushVirtualAddressSpaceEx, HvFlushVirtualAddressList, and
HvFlushVirtualAddressListEx) that allow operating systems to more
efficiently manage the virtual TLB. The L1 hypervisor can choose to
allow its guest to use those hypercalls and delegate the responsibility
to handle them to the L0 hypervisor. This requires the use of a
partition assist page."
Add the Direct Virtual Flush support for SVM.
