c3f65d39fa xpp: BRI: remove trivial BRISTUFF wrappers
Now that legacy BRISTUFF code is gone, some wrapper
functions became trivial. Removed these wrappers
and inlined their contents.

d624adb358 dahdi: First span registered becomes master by default.
r10205 "dahdi: Check for master in DAHDI_STARTUP / resolves MeetMe
regression." did not handle the case for the wcb4xxp driver since it
would set DAHDI_FLAG_RUNNING as part of the probe. Therefore, the
DAHDI_STARTUP ioctl was never processed for it, creating a situation
where audio is missing on channels that are conferenced with channels on
the BRI spans.

1bf7ebc42f wct4xxp: Fix condition where hardware echo canceler erroneously mutes DTMF.
Commit r9750 "wct4xxp: Reduce the memory footprint of the hardware
echocanceler.", as part of reducing the non-pageable memory required to
support the VPMOCT064 and VPMOCT128, disabled caching of some hardware
echocan registers. This resulted in more physical reads to the echo
canceler. These new read transactions exposed an existing issue where
sometimes reads could be turned into writes which put a channel into an
unintended state preventing Asterisk from detecting any DTMF.

This issue is resolved by ensuring that the write signal to the Octasic
part is explicitly cleared between when the address is presented on the
bus and when the read and chip select signals are asserted. The cost is
an increase in the average time to enable / disable echo cancellation by
about 5 us on one Intel Xeon X3220 test machine (~250ns increase per
read from the Octasic part and 20 reads to enable / disable a channel).

This commit resolves a behavioral regression first introduced in 2.5.0
and 2.4.1 which could take many calls before revealing itself. This
change only affects cards with a VPMOCT128 or VPMOCT064 installed.

9fb13e2f6c wctdm24xxp: Set dahdi_span.devicetype string in one place.
Currently the devicetype string was set both when the device was first
allocated and updated when an echocanceler was detected. For simplicity,
combine both these steps into a single function.

This change also replaces an improper use of strncat with strlcat.

Additionally, on the 2.5 branch, this change actually makes r10206

fcbde772c4 xpp: fxs: bugfix for 2fxs+6fxo cards
* Bug sympthoms: wrong FSK VMWI sent few seconds after
  offhook. That was caused because the driver kept
  polling the (physically unconnected) digital inputs.
  [note: a workaround for drivers without this patch
   is to zero the 'xpd_fxs.poll_digital_inputs' parameter.]

* Also, the digital_inputs/digital_output masks were
  calculate using a different condition.

* Now we determine number of channels, digital inputs and
  digital outputs in a single place and use this info
  later to calculate the correct masks.

* We poll only if there are digital_inputs

* We added a sanity check in process_digital_inputs, so
  we get a notice if it's called on an xpd without digital
  inputs (e.g: hypothetic firmware bug).

2bc2ebd1de dahdi: Check for master in DAHDI_STARTUP / resolves MeetMe regression.
There were a couple of reports that MeetMe conferences were not
working in 2.5.0.1 and that downgrading to 2.4.1.2 resolved the
issue. This could occur if there were no analog spans in a system,
and all the digital spans were out of alarm before DAHDI_STARTUP
ioctl was called by dahdi_cfg. If the spans were *not* out of alarm,
they would be marked master when the span changes it's alarm state.

This would result in a condition where no spans were marked as the
"master" and so the core timer was handling conferencing. The core
timer runs by default at 4ms and most board drivers run at 1ms
intervals, but a channel currently only buffers up 2ms of data when
conferenced. Therefore, 2ms of audio from a board was continuously
dropped from the conference every 4ms by default.

This fixes a regression first introduced in 2.5.0 which was
specifically added in revision r9611 "dahdi: Do not locate new
master in interrupt context."

d6075a4c78 dahdi: Decrease the initial coretimer delay to 4ms from 1 second.
DAHDI currently waits a second before checking if a board driver is
calling dahdi_receive and switching to internal timing. Some versions of
Asterisk (I was looking at 1.4.42 when writing this) only wait 300ms for
a timer to expire when first starting and verifying that DAHDI is
properly configured. This can result in a

"ERROR[27673] asterisk.c: Asterisk has detected a problem with your DAHDI
configuration and will shutdown for your protection. You have options:"

message if asterisk is started soon after loading DAHDI.

This change sets the inital polling interval to the same as that used
during normal coretimer operation, 4ms. The interval will still be
slowed to 1 second if a board driver starts calling dahdi_receive().

08ce93306d wctdm24xxp: Use our own free list for IRQ commands.
Really only *necessary* when SLAB debugging is enabled, but in that
case, can reduce the chance of latency bumps when first loading the
driver. Otherwise the constant slab poisoning / checking in interrupt
context from the kmalloc / kfrees is too much.

dac1d88399 wct4xxp: Bug in timing cable with different span density cards
The logic loops through the static cards[] array to determine timing,
    but the subloop was based off the current card's numspans member.
    This could cause a null dereference in the case where two cards of
    different span densities were connected via timing cables.

r10082 "wctc4xxp: Cleanup in-flight commands when halting due to

cmd_list_lock would be unlocked twice when the board is halted due to a

da2406db64 wcte12xp, wctdm24xxp: Force local interrupts off in the interrupt handler.
r10066 "wctdm24xxp, wcte12xp: Run the ISR with interrupts disabled."
requested that the interrupt handler be run in "fast" mode (disabled)
but this isn't necessarily guaranteed.

This patch makes the interrupt handler itself disable all the interrupts.
Linux commit 470c66239ef0336429b35345f3f615d47341e13b [1] contains a comment
about why this is necessary.

Currently dahdi_receive is called on all channels in the context of the
master dynamic span. If one span (not the master) receive two packets
before the master span received a packet, the older packet on the
dynamic span would end up lost because the "readchunk" for the
channels would be overwritten by the new packet. DAHLIN-245

9fd43e0139 wctc4xxp: Cleanup in-flight commands when halting due to hardware error.
On one system I was seeing the board reset in the middle of a
transaction. Any commands that were on the response list when this would
happen would never be completed and the process would then be stuck in
an uninterruptible sleep. This change also prevents the driver from
sleeping in timer context, which would result in a kernel panic.

This change at least lets an error message propogate back to the user.

1813c9ad09 wcb4xxp: Prevent null pointer dereference on spanconfig
In the rare case where spanconfig is called while there is pending data
on the hdlc channel, the hdlc_getbuf interrupt could try to read from
the hdlc buffer before the channel was fully setup. This could
potentially result in a null pointer dereference. This condition has
existed since the creation of the wcb4xxp driver.

Revision 9995 "dahdi: Always attach hwec to a channel if available" had
an error where if a driver did not even support an option of hardware
echocan, dahdi-base would take that to mean there always was a hardware
echocan available on the channel.

071cfdc983 wctdm24xxp, wcte12xp: Run the ISR with interrupts disabled.
Revision 9886, "wcte12xp: Use the in-hardirq versions of
dahdi_receive/dahdi_transmit", changed the call into dahdi_receive and
dahdi_transmit to use versions that assume local interrupts are already
disabled.  Not all versions of the kernel run interrupt service routines with
all interrupts disabled and therefore it was possible to lock up a CPU with a
recursive grab of the chan_lock.

When LOCKDEP was enabled (on debug kernels) interrupt handlers were run
atomically so this problem would only occur on pre 2.6.35 kernels that did not
have lockdep enabled.

64b150eb96 oct612x: Increase the size of some of the instance variables.
Revision 9750 "wct4xxp: Reduce the memory footprint of the hardware
echocanceler" reduced the number of bits used to store some structure
members. Some of the new field lengths were unable to store all the
possible values the API as used assigned to the fields, resulting in
channels never entering power down mode when they were disabled like
they were previously.

The change for byEchoOperationMode was found in testing the operation of
the VPMOCT032 which currently uses the same code. The others were done
via a review of the API doc.

This change represents negligable risk and contains no logic changes.
It only increases the memory footprint of the API instance in the
kernel.
