Define the VMCS execution control flags (consumed by KVM) using their associated VMX_FEATURE_* to provide a strong hint that new VMX features are expected to be added to VMX_FEATURE and considered for reporting via /proc/cpuinfo.
No functional change intended.

checkpatch correctly complains here:
WARNING: 'OFFSETING' may be misspelled - perhaps 'OFFSETTING'? #80: FILE: arch/x86/include/asm/vmx.h:26: +#define CPU_BASED_USE_TSC_OFFSETING VMCS_CONTROL_BIT(TSC_OFFSETTING)
and VMX_FEATURE_TSC_OFFSETTING is correct.
Should I fix it up to CPU_BASED_USE_TSC_OFFSETTING while applying?
