x86: enable VIA CPU support
Newer VIA CPUs have both 64-bit and VMX support. Enable them to be recognized for these purposes, at once stripping off any 32-bit CPU only bits from the respective CPU support file, and adding 64-bit ones found in recent Linux. This particularly implies untying the VMX == Intel assumption in a few places. Signed-off-by: Jan Beulich <jbeulich@suse.com> Acked-by: Keir Fraser <keir@xen.org>
