I will look at committing this.

BTW, The netlogic(RMI) contributed code had a different implementation
for this. The User Reserved Instruction exception had a fast path for
RDHWR which used k0/k1 and returned the value without taking the full
trap.   I hadn't looked at adding that either (mostly because I did
not see an immediate requirement).

Another emulation missing in the kernel is for floating point...
