This is always true currently but will not necessarily be in the future.

Reduces the number of locks that must be grabbed and released in interrupt
context. On one 3.06Ghz Intel Xeon test machine, drops the average time in
the interrupt handler from 29.83 us to 23.10 us.

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
to crank the performance up past 11.

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).

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.
