enable/disable cpuid bits"):
Allow to enable/disable SVM specific cpuid bits
in the guest config file via cpuid config option.
Also allow to enable/disable the hypervisor cpuid bit
in the guest config file. We need to disable the
hypervisor cpuid bit to get Hyper-V going.
The change itself looks plausible to me. However I don't know much
about cpuid; can you get an ack from a hypervisor maintainer or an
suitable expert ?
Keir? Tim?
I think the hypervisor bit should be given a better name than 'raz' --
although it is read-as-zero on real hardware that doesn't distinguish it
from other raz bits, or describe what it does.
'hypervisor' maybe, to match 'X86_FEATURE_HYPERVISOR' elsewhere in the
Xen code?
