History
Bruce M Simpson 69599f22f0 Further improve locking in xl(4): 
- Avoid an additional lock acquire/release when leaving xl_intr(), by
   changing xl_start*() to xl_start*_locked(), and calling the appropriate
   routine by chip revision (as the DMA descriptors are different).

 - Simplify the appropriate routines now that they are called with the
   lock held.

This should save a significant amount of CPU cycles spent on servicing
each interrupt for both UP and SMP whilst remaining MPSAFE.
