Paolo Bonzini	dd4516aee3	selftests: kvm: move vm_xsave_req_perm call to amx_test ... There is no need for tests other than amx_test to enable dynamic xsave states. Remove the call to vm_xsave_req_perm from generic code, and move it inside the test. While at it, allow customizing the bit that is requested, so that future tests can use it differently.

Yang Zhong	bf70636d94	selftest: kvm: Add amx selftest ... This selftest covers two aspects of AMX. The first is triggering #NM exception and checking the MSR XFD_ERR value. The second case is loading tile config and tile data into guest registers and trapping to the host side for a complete save/load of the guest state. TMM0 is also checked against memory data after save/restore.
