        src/sys/dev/nvmm/x86: nvmm_x86.c nvmm_x86.h nvmm_x86_svm.c
            nvmm_x86_vmx.c

Log Message:
Choose which CPUID bits to allow, rather than which bits to disallow. This
is clearer, and also forward compatible with future CPUs.

While here be more consistent when allowing the bits, and sync between
nvmm-amd and nvmm-intel. Also make sure to disallow AVX, because the guest
state we provide is only x86+SSE. Fixes a CentOS panic when booting on
NVMM, reported by Jared McNeill, thanks.
