    This will allow us to read a whole page with KVMI_READ_PHYSICAL.

  2. kvmi: change the error code used for KVMI_READ_PHYSICAL and KVMI_WRIT… 

    …E_PHYSICAL

Until now, the introspection connection was closed on invalid gpa/size
pairs and if the guest page could not be mapped it returned KVM_EINVAL,

From now on, the kernel will return KVM_EINVAL (without closing the
connection) for the first case and KVM_ENOENT for the second.
