I've found that this version is wrong (register lists are not
terminated for these
two cores), so I sent v2. After that I've found that it's still wrong,
i.e. the register
105 is still not available with v2. I dug a bit deeper and it looks
like register
handling should probably be the same for both system and linux-user cases.
I'll post v3 after some more testing in a few days.
