* Add a bus_if.m method - get_domain() - returning the VM domain or
ENOENT if the device isn't in a VM domain;
* Add bus methods to print out the domain of the device if appropriate;
* Add code in srat.c to save the PXM -> VM domain mapping that's done and
expose a function to translate VM domain -> PXM;
* Add ACPI and ACPI PCI methods to check if the bus has a _PXM attribute
and if so map it to the VM domain;
* (.. yes, this works recursively.)
* Have the pci bus glue print out the device VM domain if present.
Note: this is just the plumbing to start enumerating information -
it doesn't at all modify behaviour.

This partitular case is the only path where the mbuf could be NULL.
udp_append() checked for a NULL mbuf only after invoking the tunneling
callback. Our only in tree tunneling callback - SCTP - assumed a non
NULL mbuf, and it is a bit odd to make the callbacks responsible for
checking this condition.
This also reduces the differences between the IPv4 and IPv6 code.

The M_FLOWID flag should be propagated to the new mbuf pkthdr in
m_move_pkthdr() and m_dup_pkthdr(). The new mbuf already got the
existing flowid value, but would be ignored since the flag was
not set.

1. ERESTART is not only returned when the revoke count changed. It
is also returned when a signal is received. While a change in
the revoke count should be ignored, a signal should not.
2. Waiting until the output queue is entirely drained can cause a
hang when the underlying device is stuck or broken.
Have tty_drain() take care of this by telling it when we're leaving.
When leaving, tty_drain() will use a timed wait to address point 2
above and it will check the revoke count to handle point 1 above.
The timeout is set to 1 second, which is arbitrary and long enough
to expect a change in the output queue.

includes the function pointer, argument, and whether or not it was run from
hardware interrupt context. The callwheel is marked idle when each handler
completes. This effectively logs the duration of each callout routine in
the graph.

where as there are limited number(32) of mfi commands in the pool.
The mfi command pool is now restricted to 27 simultaneous accesses by using
a counting semaphore while calling the passthru function.
In the mrsas_cam.c source file there was a same function name mrsas_poll(),
which was same as the mrsas_poll() implemented in the mrsas.c file for the
polling interface.
To clearly distinguish the functionality by usage we have renamed the former
as mrsas_cam_poll().
In the passthru function let's say it has got an mfi command from the pool
but it has failed in one of the DMA function call which will lead to leak
an mfi command because in the ERROR case it directly returns and not freeing up
the occupied mfi command.
