voicebus_quiesce is like voicebus_stop, except that it doesn't wait for any
information to come back from the card. This prevents kexec from blocking
waiting for information from a potentially dead card.

Since there never was a VPMADT032 module shipped with non-volatile
memory no need to check that bit contantly in interrupt context. Also

Span registration is the last step in during initialization and it
should be the first on unregistration. I also was hit by this when
looking at adding other members to the span and made the assumption that
the span was in a consistent state during unregistration.

Changed the echocan factory name to a function (get_name) called to get the
name. This allows a factory to return a different name when being called in
reference to a channel such as in the case of hardware echo cancellers. To
further accommodate this change for HWEC, a new echocan_name function was
added to the span ops struct and is used in hwec_factory in dahdi-base for
all cards that support hardware echo cancellation.

The loopup/loopdown T1 maintenance feature in the single through quad-span
drivers now function properly, according to AT&T TR54016, by sending a
full rate pattern down the line. T1.403 ESF/Data Link patterns are not
supported currently.
Also grouped all the maint reset register clears under a single irq lock

The wcte12xp does all the checking for alarm in a user space workqueue.
Most of this time is spent sleeping waiting for reads from the framer to
complete. Tasks in uninterruptible sleeps are added to running tasks
for the purposes of calculating load average. This change makes the
sleeps interruptible so as to not affect the load average as much.
For example, the following command will load and configure the driver and
then print the load average every 10 seconds.
]# modprobe wcte12xp && dahdi_cfg && ((x=12)); while [[ $x -gt 0 ]]; do cat
/proc/loadavg; sleep 10; let x=$x-1; done

The check for DEFINE_SPINLOCK was spread throughout the source tree. If
not defined we can just define it in inlucde/dahdi/kernel.h. Now
include/dahdi/kernel.h is the only place that references
SPIN_LOCK_UNLOCKED (which breaks lockdep checking if DEFINE_SPINLOCK is
otherwise defined in the kernel).

Upon shutdown, both drivers would attempt to power down external
interfaces, but never attempted to bring them back up when the span was
restarted. Removing that code allows the driver to work properly until
a better solution can be found.

This needs some more testing before it's on by default. If the card is
otherwise functioning, these messages may be confusing to the user. If
the card is not functioning, the driver can be reloaded with debug to
check for this condition.
