[PATCH 0/4] ipmi: Allow dynamic device IDs

[Jeremy Kerr <jk@ozlabs.org>]

This series implements a more dynamic method of reporting BMC version &
identification. The current method of registering versions and IDs
during ipmi_register_smi means that if a BMC is upgraded during a boot,
the IPMI core code will report old version information.

We do this by querying the BMC (using a Get Device ID request) at smi
registration in the IPMI core code, and when the sysfs version & id
attributes are accessed.

The core of the change is in patch 3/4. Patches 1 and 2 implement a
couple of minor API changes leading up to this.

Patch 4 converts the powernv IPMI driver to use the dynamic IDs; the
behaviour of the other SMIs is not changed by this series. However,
if there's interest, I'm happy to alter the existing SMIs too, in a
follow-up series.

Questions & comments most welcome.

Cheers,

	
Jeremy
