Move the shutdown handling to a shutdown function called from

To handle hot remove of interfaces, a lot of rework had to be
done to the locking.  Several things were switched over to srcu
and shutdown for users and interfaces was added for cleaner
shutdown.

Since things that IPMI uses can be hot-swapped, the users and
interfaces really need to be able to handle this.

Add the functions so the users and interfaces can implement
them, the actual function will be added after everything is
ready.

The mutex didn't really serve any useful purpose, from what I can
tell, and it would just get in the way.  So remove it.

Removing that required a mutex around the default value setting and
getting, so just use the receive mutex for that.

Also pull the fasync stuff outside of the lock for adding the data
to the queue, since it didn't need to be there.

This is a cleaner interface and the main IPMI panic handler does setup
required by the watchdog handler.
Signed-off-by: NCorey Minyard <cminyard@mvista.com>

Users of the IPMI code had their own panic handlers, but the
order was not necessarily right, the base IPMI code would
need to handle the panic first, and the user had no way to
know if the IPMI interface could run at panic time.

Add a panic handler to the user interface, it is called if
non-NULL and the interface the user is on is capable of panic
handling.  It also cleans up the panic log handling a bit to
reuse the existing interface loop in the main panic handler.

And clean broken strings.
Signed-off-by: NCorey Minyard <cminyard@mvista.com>

Simplify things by creating one set of message handling data for
setting the watchdog and doing a heartbeat.  Rework the locking
to avoid some (probably not very important) races and to avoid
a fairly unlikely infinite recursion.

Get rid of ipmi_ignore_heartbeat, it wasn't used, and use
watchdog_user to tell if we have a working IPMI device below
us.

If you send a command to another BMC that might take some extra
time, increase the timeouts temporarily.
Signed-off-by: NCorey Minyard <cminyard@mvista.com>

By default the retry timeout is 1 second.  Allow that to be modified,
primarily for slow operations, like firmware writes.

Also, the timeout was driven by a 1 second timer, so 1 second really
meant between 0 and 1 second.  Set the default to 2 seconds so it
means between 1 and 2 seconds.

Also allow the time the interface automatically stays in mainenance
mode to be modified from it's default 30 seconds.

Also consolidate some of the timeout and retry setup.

  reaches 6M+ objects reachable from HEAD.

  I was joking around that that's when I should switch to 5.0, because
  3.0 happened at the 2M mark, and 4.0 happened at 4M objects. But
  probably not, even if numerology is about as good a reason as any.
