Alfred Perlstein 5d8e635779 Re-enable WITNESS for GENERIC. Since the 5.x branch is mostly about
SMP we'd like as much feedback as possible from users about possible
locking problems as early as possible.

To negate most of the performance impact I've also enabled
WITNESS_SKIPSPIN.  I've done this as we've been running WITNESS
over the spinlock code for a while without incident and it goes a
long way to making the performance problems of WITNESS much more
bearable.

Users who should be running current should know about turning WITNESS
off for performance reasons.

That said and done, WITNESS could/should be made into a tuneable,
but we'll leave that as an excersize to those that want to disable
it without a kernel recompile.
