[PATCH] IPMI base patch to fix channel handling and add polling
This patch fixes some problems with handling of channel detection in the
driver. Some systems that are IPMI 1.5 do not implement the channel query
command. Also, the interface has to be fully up before the command is
ready.
This patch also adds a polling interface; this is required for situations
where interrupts are not running, but the system must still issue IPMI
commands, like when taking a crash dump.
It also updates the driver version to v32.
