Allow userspace reads and writes to `VMX_CONTROL_ENTRY_CONTROLS` field of VMCS. Which is primarily used for enabling long mode and loading of certain MSRs on VM Entry. As far as I know this field only controls the behaviour of the VCPU and would not allow userspace to violate any kernel properties such as disabling external interrupt exiting or EPT. The effects of bits in this field are defined in Chapter 27.8 "VM-ENTRY CONTROL FIELDS" of the Intel SDM Order Number: 325462-090US February 2026. Signed-off-by: Bill Nguyen <bill.nguyen@unsw.edu.au>
