45ac6a30f9 voicebus, wcaxx, wct4xxp: Remove include of pci-aspm.h
Linux 5.4, in commit  (7ce2e76a0420801fb4b53b9e685094 "PCI: Move ASPM
declarations to linux/pci.h") [1], removed pci-aspm.h.

This commit removes the global include of pci-aspm.h in include/dahdi/kernel.h
(because it only pertains to certain drivers), and moves the conditional include
into only the drivers that need it.

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.

2c97dd21bd wcte12xp, wctdm24xxp: Add compile-time option to disable ASPM for PCIe devices.
Certain BIOSes appear to enable ASPM even though it is not fully supported by
the platform. Also, since the PCIe links for TDM cards are always in use it
does not make sense to allow them to transition to the disabled state.

Just turn off power management on the PCIe links completely. For more
information see http://lwn.net/Articles/449448/.

40945a2a00 wcte12xp, wctdm24xxp: decriptor_list.count does not need to be atomic.
It is only ever accessed in interrupt context anyway. Saves several
hundred nanoseconds from hard interrupt context.

58c1168185 wctdm24xxp, wcte12xp: Add voicebus_quiesce function.
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.

50f51ee459 voicebus: Update the network debug device to use dma_pools.
r9402 switched to dma_pool for the SFRAMES. This updates the network
debug device to use the dma_pools for SFRAME allocation.

5618e9e812 wcte12xp, wctdm24xxp: Convert vbb cache from kmem_cache to dma_pool.
The voicebus interface constantly uses the same buffers for moving data
to/from the card.  A fixed pool has less overhead in this case than
constantly mapping/unmapping the kmem_cache_alloced buffers.

Saves about ~2.608 us for each run of vb_isr on a 2.40 GHz Xeon test
machine.

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.
