Put the target's fetch agent into reset state before the underlying ORB
DMA is unmapped and the ->done handler is called.  It is highly unlikely
but the target could access that ORB right before sbp2 sends the reset

struct hpsb_highlevel's struct module *owner is neither used by the IEEE
1394 core nor set by any of the in-tree drivers or the two out-of-tree

documented.  An unscheduled removal seems acceptable.

This allows workqueue users to run just their own pending work, rather
than wait for the whole workqueue to finish running.  This solves the
deadlock with networking libphy that was due to other workqueue entries
possibly needing a lock that was held by the routine that wanted to
flush its own work.

It's not wonderful: if you absolutely need to synchronize with the work
function having been executed, any user strictly speaking should have
its own completion tracking logic, since when we run things explicitly
by hand, the generic workqueue layer can no longer help us synchronize.

Also, this is strictly only usable for work that has been scheduled
without any delayed timers.  You can not mix the new interface with
schedule_delayed_work().

But it's better than what we had currently.

The IPMI BT subdriver has been patched to survive "long busy" timeouts seen
during firmware upgrades and resets.  The patch never returns the HOSED state,
synthesizes response messages with meaningful completion codes, and recovers
gracefully when the hardware finishes the long busy.  The subdriver now issues
a "Get BT Capabilities" command and properly uses those results.  More
informative completion codes are returned on error from transaction starts;
this logic was propogated to the KCS and SMIC subdrivers.  Finally, indent and
other style quirks were normalized.

When the IPMI message handler requested that the interface look for events,
the ipmi_si driver would request flags, see if the event buffer full flag was

it cuts one message out of the transaction if there happens to be events, and
it will fetch events even if the event buffer was not full.

nature to timeout and generate annoying logs, or possibly cause other bad
