A number of small changes for the various system interface drivers,
consolidated from a number of patches from Matt Domsch.
Clear B2H_ATN and drain the BMC message buffer on command timeout. This
prevents further commands from failing after a timeout.
Add bt_debug and smic_debug module parameters, expose them in sysfs. This
lets you enable and disable debugging messages at runtime.
Unsigned jiffies math in ipmi_si_intf.c causes a too-large value to be passed
to ->event() after jiffies wrap-around. The BT driver had caught this, but
didn't know how to fix it. Now all calls to ->event() use a sane value for
time.
Increase timeout for commands handed to the BT driver from 2 seconds to 5
seconds. This is necessary particularly when the previous command was a
"Clear SEL", as that command completes, yet the BMC isn't really ready to
handle another command yet.
Silence BT debugging messages which were being printed on the console.
Increase SMIC timeout form 1/10s to 2s. This is needed on Dell PowerEdge 2650
and PowerEdge 750 with ERA/O cards to allow commands to complete without
timing out.
Adds kcs_debug module param, to match behavior of BT and SMIC. This also
prevents messages from being sent to the console unless explicitly requested.
