[Qemu-devel] [PATCH v3 0/3] ipmi: Fix some minor issues

[minyard]

I think this is ready, can someone pick this up?

Thanks,

-corey

Changes from v2:

 * Add Cédric's reviews

Changes from v1:

 * Get the data from the proper offset in the command array.
 * Use {} on all if statements.

[Qemu-devel] [PATCH v3 1/3] ipmi: Fix SEL get/set time commands

[minyard]

From: Corey Minyard <cminyard@mvista.com>

The minimum message size was on the wrong commands, for getting
the time it's zero and for setting the time it's 6.

[Qemu-devel] [PATCH v3 2/3] ipmi: Don't set the timestamp on add events that don't have it

[minyard]

From: Corey Minyard <cminyard@mvista.com>

According to the spec, from section "32.3 OEM SEL Record - Type
E0h-FFh", event types from 0x0e to 0xff do not have a timestamp.
So don't set it when adding those types.  This required putting
the timestamp in a temporary buffer, since it's still required
to set the last addition time.

[Qemu-devel] [PATCH v3 3/3] ipmi: Add the platform event message command

[minyard]

From: Corey Minyard <cminyard@mvista.com>

This lets an event be added to the SEL as if a sensor had generated
it.  The OpenIPMI driver uses it for storing panic event information.
