[SVN commits to the Digium repositories]

New Revision: 9845

URL: http://svnview.digium.com/svn/dahdi?view=rev&rev=9845
Log:
wcte12xp: Use the in-hardirq versions of dahdi_receive/dahdi_transmit.

We are in hard-irq context already, so we do not need to disable all
local interrupts. On one 3.06GHz Xeon test machine, drops the average
time in the interrupt handler from 23.10 us to 21.87 us.
