Thread-topic:	[PATCH]Do some checks and settings of CR0 according to VMX capability MSRs

According to SDM Vol 3B 19.8 Software should consult the VMX capability MSRs to determine how bits

in CR0 are set, VMXON fails if any of these bits contains an unsupported value. And according to

SDM Vol 3A 2.5, 3B 21.3 and 2A MOV-MOV to/from Control Registers, setting upper 32 bits of CR0

results in a general-protection exception and setting the reserved bits in lower 32 bits of CR0 are ignored .

In accordance with above-mentioned, the patch is attached to do some checks and settings of CR0.
