9e95400e5b Add a bit more caveat text about MUTEX_PROFILING -- try to avoid using it 
with other profiling and debugging options, such as INVARIANTS, WITNESS,
kernel profiling, etc.  They all interfere with each other nastily and
will generate fairly useless results.

98c926b20f Add a mechanism for associating a mutex with a callout when the 
callout is first initialised, using a new function callout_init_mtx().
The callout system will acquire this mutex before calling the callout
function and release it on return.

In addition, the callout system uses the mutex to avoid most of the
complications and race conditions inherent in asynchronous timer
facilities, so mutex-protected callouts have much simpler semantics.
As long as the mutex is held when invoking callout_stop() or
callout_reset(), then these functions will guarantee that the callout
will be stopped, even if softclock() had already begun to process
the callout.

Existing Giant-locked callouts will automatically pick up the new
race-free semantics. This should close a number of race conditions
in the USB code and probably other areas of the kernel too.

There should be no change in behaviour for "MP-safe" callouts; these
still need to use the techniques mentioned in timeout(9) to avoid
race conditions.

641a1aa10d Attempt to describe the race conditions that must be considered 
when using the callout subsystem. Show how the callout_pending(),
callout_active() and callout_deactivate() macros can be used to
achieve simpler race-free callout semantics in many situations.
