That's up to the next patch.
The watchdog one? I don't see any direct connection to this function.
Does a reset always involve a CPU state change? If that's what we're
relying on, it least deserves a code comment in this function.
Otherwise it looks like no special handling is required when setting
SREG SPRs in KVM-compatible code (i.e. not code that is only used in
TCG mode).
