Currently, secondary execution controls are divided in three groups:
- static, depending mostly on the module arguments or the processor
(vmx_secondary_exec_control)
- static, depending on CPUID (vmx_cpuid_update)
- dynamic, depending on nested VMX or local APIC state
Because walking CPUID is expensive, prepare_vmcs02 is using only
the first group. This however is unnecessarily complicated. Just
cache the static secondary execution controls, and then prepare_vmcs02
does not need to compute them every time. Computation of all static
secondary execution controls is now kept in a single function,
vmx_compute_secondary_exec_control.
