[v3] x86: make cpu virtualization support configurable

[XEN PATCH v3 15/16] x86/vmx: replace CONFIG_HVM with CONFIG_VMX in vmx.h

Posted by Sergiy Kibrik 5 months, 3 weeks ago

As now we got a separate config option for VMX which itself depends on
CONFIG_HVM, we need to use it to provide vmx_pi_hooks_{assign,deassign}
stubs for case when VMX is disabled while HVM is enabled.

changes in v3:
 - use CONFIG_VMX instead of CONFIG_HVM to provide stubs, instead of guarding
   calls to vmx_pi_hooks_{assign,deassign} in iommu/vt-d code
