Pull up following revision(s) (requested by maxv in ticket #475):
tests/lib/libnvmm/h_mem_assist.c: revision 1.18
sys/dev/nvmm/x86/nvmm_x86_vmx.c: revision 1.45
sys/dev/nvmm/x86/nvmm_x86_svm.c: revision 1.54
Hide XSAVES-specific stuff and the masked extended states.
Several improvements. In particular, reduce CS.limit, because Intel CPUs
perform strict sanity checks, and the previous (too high) limit caused the
VM entry to fail.
