Bit19 (CR4_KL) of CR4 is CPU KeyLocker feature enable bit. Hypervisor traps the bit's writing to track the keylocker feature on/off of guest. While the bit is set by guest, - set cr4_kl_enabled to indicate the vcpu's keylocker feature enabled status - load vcpu's IWKey in host (will add in later patch) While the bit is clear by guest, - clear cr4_kl_enabled This patch trap and passthru the CR4_KL bit to guest for operation.
