KVM: nVMX: do not pin the VMCS12
Since the current implementation of VMCS12 does a memcpy in and out of guest memory, we do not need current_vmcs12 and current_vmcs12_page anymore. current_vmptr is enough to read and write the VMCS12. And David Matlack noted: This patch also fixes dirty tracking (memslot->dirty_bitmap) of the VMCS12 page by using kvm_write_guest. nested_release_page() only marks the struct page dirty.
