A new "Enable ENCLS exiting" control bit (bit 15) is defined in the secondary processor-based VM execution control.
* 1-Setting of "Enable ENCLS exiting" enables ENCLS-exiting bitmap control, which is a new 64-bit ENCLS-exiting bitmap control field added to VMX VMCS (0202EH) to control VMEXIT on ENCLS leaf functions.
* ACRN does not emulate ENCLS leaf functions and will not enable ENCLS exiting.
