I would like to reorder this to be the same as struct reg as it will allow us to memcpy them in a few places in the kernel. The order of this has been fixed, but not been copied over as struct reg is part of the ABI.
The trapframe may also need to be reordered, but this is less of a concern as it is only used within the kernel.
