Thread-topic: [SVM][PATCH] Add test for SVM Disabled via BIOS
Newer BIOS implementations will be able to disable the SVM feature,
although an additional test of an MSR (VMCR 0xC0010114 bit 4) is
necessary (set equals disabled). Bit 4 of MSR 0xc0010114 returns 0 (SVM
enabled) on machines with older BIOS' without the SVM disable feature
support.
Applies cleanly to 11730.

Know that it is very late for 3.0.3, would be good to have this code in
3.0.3-rcN if possible.
Please apply to xen-unstable.hg
Please apply to xen-3.0.3-testing
