Andrew,

The following patch is ready for inclusion; it makes the IPMI
watchdog more consistent with the other watchdog drivers.

I have tested this and it seems to work correctly.  I also added docs
for the interface change.

- support disabling watchdog by writing 'V' to device.
- unify printk()
- use atomic bit operations on ipmi_wdog_open
