76f35e5d31 live_dahdi: rsync to /tmp/dahdi
* Change the destination of rsync to /tmp/dahdi
* Add variable LIVE_DAHDI_RSYNC_DIR to allow overriding this.

daa79cc634 live_dahdi: only check for TOOLS_DIR when used
Only check that TOOLD_DIR is valid when it is actually needed (configure,
install, config). This allows not checking for it with *load on a
rsync-ed copy.

d013943b4b make_version: Use 'git rev-parse' if only looking for a sha5.
Different versions of git have variability in how the log output looks.
Instead of git log, we can use git rev-parse directly.

4deae0c8ea wctdm24xxp: Replace 'schluffen()' with 'interruptible_sleep_on()'
'schluffen()' essentially duplicates the functionality of the standard
Linux 'interruptible_sleep_on()' function.

There may still be some race conditions that can be closed here, but
most of the command queue processing is sloted for conversion to
something more like in the single span driver in order to reduce the
time in interrupt context spent scanning for commands to the modules.

a170389509 dahdi: Close race between checking IOMUX condition and sleeping.
wake_up_interruptible() will change the state of waiting tasks back to
TASK_RUNNING, therefore, we want to ensure we set TASK_INTERRUPTIBLE
before checking the conditions that we're going to sleep on.

In practice, this closes a small window were the caller may be put to
sleep when the condition is true, and have to wait for another event to
come in order to wake from the sleep.

a782b4de71 dahdi: 'schluffen()' -> 'interruptible_sleep_on()' or 'wait_event_interruptible()'
'interruptible_sleep_on()' is the Linux equivalent of 'tsleep()'.  When
we're sleeping for a condition, we can also just use
wait_event_interruptible to close a potential race where the condition
goes true between the time we checked it and when we go to sleep waiting
on the event.

8d29ecb783 wctc4xxp: 'WARN_ON(1)' -> 'dev_info(...' on channel creation failure.
If the DSP ever finds it's way into a bad state it can be possible for a
timeslot to get 'wedged'.  All attempts to create a channel in a wedged
timeslot will fail and the WARN_ON macro can quickly fill the logs.

This change adds some more debugging information (which timeslot is wedged)
along with the result code from the DSP and puts it all behind a
printk_ratelimit.

Fixes a regression singce r8873: if pri_protocol is not explicitly set
(in /etc/dahdi/xpp.conf) and the device has (licences for) less than 4
"PRI" (E1/T1) ports, the initialization script will attempt to read from
a non-existing SysFS file, and bail out, resulting in a the device
failing to initialize.

For those non-existing ports we can just skip that part of the
initialization. So we just skip it.

Work around: explicitly set pri_protocol to E1 or T1, as needed.

1c462653e7 dahdi: Remove bigzaplock by converting chan_lock to spinlock_t.
The bigzaplock was used to prevent changes to all the channels during
masterspan processing while conference parameters were changing.  The
master span processing also took a global lock out on the chan_lock to
prevent new channels from being registered or unregistered during
processing.  Instead of grabbing both those locks, just changing the
semantics of chan_lock to those of bigzaplock seems to fit the bill and
removes another lock from the driver (and saves ~10 ns on a 2.40 GHz
Xeon in prcocess_masterspan)

chan_lock is a candidate for conversion to RCU but usage in conferencing
(bigzaplock type usage) needs to be audited carefully before conversion.

Very slight performance increase when timertest is running in the
background.  Measured at ~10 ns improvement over 10K samples.

283235686d Move test for DEFINE_SPINLOCK into include/dahdi/kernel.h
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).

731b5868d4 dahdi: Allow core DAHDI software timing to work when DAHDI_CHUNKSIZE > 8.
When no hardware spans are configured DAHDI will use a kernel timer in order
provide timing for conferences. This is what dahdi_dummy historically was used
for. When kernel timers are used to provide timing DAHDI can both potentially
slow the rate at which time timer runs and also needs to account for how many
milliseconds of audio are processed for each 'tick' of process_masterspan.

The result is that if you are only using DAHDI for app_meetme, you can change
DAHDI_CHUNKSIZE to 40 (5ms) or 80 (10ms) bytes to reduce overhead since user
space is dealing with chunks of 20ms by default anyway.

NOTE: If you set this, you may still need to comment out the board drivers in
drivers/dahdi/Kbuild since they all do not support operating with a
DAHDI_CHUNKSIZE != 8 currently.

d08cdac785 dahdi: Only disable/enable interrupts once when iterating through channels.
dahdi_receive, dahdi_transmit, and dahdi_ec_span are mostly called from
interrupt context anyway, so we can save a few cycles by not saving and
restoring the interrupt flags for every channel.

On one 2.40GHz Xeon test machine, for a span with 24 channels w/o echocan
enabled with ~10000 samples:

Function        Avg Before   Avg After
======================================
dahdi_receive   2.109 us     1.547 us
dahdi_transmit  3.203 us     2.766 us
dahdi_ec_span   0.416 us     0.454 us

NOTE: The time went up slightly on dahdi_ec_span since I did not have
software echocan enabled and this change calls local_irq_save regardless
in dahdi_ec_span.  The slight increase in processing time in this case
is overshadowed by the savings in dahdi_receive and dahdi_transmit. If
echocan was enabled on all the channels there would be a time savings
in that dahdi_ec_span too.

When dahdi_receive/dahdi_transmit are called every millisecond (when
DAHDI_CHUNKSIZE == 8) this saves ~0.1% CPU time for each span.
