Indeed, I'm working on fixing that now. EPC is missing too (there's a
comment in there about EPC which AFAICT seems to confuse the guest
CP0_EPC with the guest PC which are distinct state for full system
emulation).

Also unfortunately the CP0 register ids provided by QEMU all
(incorrectly) lack the size part too. Remarkably it generally works
quite well despite this since KVM takes care of most of the runtime details.
