ffcd08205c xpp: Convert struct timeval -> ktime_t.
`struct timeval` has been removed from the kernel interface in 5.0 as
part of fixing the 2038 problem. ktime_t is the preferred kernel time
interface now.

02d30ab799 Remove support for kernels older than 2.6.27
There are not any major distributions that are still supporting kernels
older than 2.6.27 so we can remove many typedefs. The primary motivator
for this change is that kernel 5.0 is dropping support for timeval and
it would be ideal if the in-kernel time representation can
standardize on ktime_t, but 2.6.18 did not support the ktime
interface that was needed.

95de230835 xpp: remove independent "Unknown" XPP_VERSION
The xpp drivers were originally developed seperately and thus had their
own version number. For quite some time they no longer have this version
number and report 'Revision: Unknown'.

Get rid of this mechanism.

ffdfdfb66b xpp_usb: Fix potential corruption on clock rewind
The xpp modules use time differences for various statistics. In one case
xpp_usb creates a histogram of the time it took the system to send USB
packets (URBs). The time difference is used (after adjustments) as an
index to that array.

However if the clock happens to go back at that exact point in time, we
get to write to an arbitrary negative index in this array.

404a67d089 xpp: improve handling of USB sluggishness
* Drop PCM during sluggish events:
  - Drop both rx/tx (was only tx)
  - Drop almost all pcm until sluggishness stops (used to drop only
    single pcm each time).
  - Renamed: "drop_next_pcm" -> "drop_pcm" (to match new semantics)
  - Still allow "keep alive" PCM so Astribank will not reset FXS high-voltage.
    The "sluggish_pcm_keepalive" parameter set the rate (1/50 by default)
  - Added rx/tx drop statistics counters
  - Removed "pcm_tx_drops" (replaced by new statistics counters)

* Also improved format of /proc/xpp/XBUS-*/xpp_usb:
  - Show cummulative number of sluggish events.
  - Clearly show range (in usec) of usb_tx_delay[]

fc1824fd3c Remove support for kernels < 2.6.18
This patch removes support for kernel versions < 2.6.18, as those are
not actively supported in any major Linux distribution (except RHEL4,
which is in the "extended" support level of the product life cycle).

This removes much of the more #ifdef-rich parts of the code.

86519d1211 Remove unused variables.
gcc-4.6 now warns about variables that are set but never used. Clean up
unused variables everywhere except the oct612x subdirectory.

The oct612x should go in a separate patch in case that needs to be
pulled out into a separate project again.

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).

bf3fe05dfb wct4xxp: Moving the transmit short detection behind debug module param.
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.
