Jarkko and Dave,

I'll change to use below:

 /*
  * Update the SGX_LEPUBKEYHASH MSRs to the values specified by caller.
  * Bare-metal driver requires to update them to hash of enclave's signer
  * before EINIT. KVM needs to update them to guest's virtual MSR values
  * before doing EINIT from guest.
  */

Please let me know if are not OK with this.
