calls it rather than obtaining and releasing it a lot in proc_compare.
- Collect all of the data gathering and stick it just after the
proc_compare loop. This way, we only have to grab sched_lock once now
when handling SIGINFO. All the printf's are done after the values are
calculated.

The counters are incremented when a thread goes to sleep and decremented
either when a thread is woken up by another thread or when the sleep
times out. There existed a race where the sleep count could be decremented
twice resulting in an eventual underflow.
Move the decrementing of the "counters" to the thread initiating the sleep
and thus remedy the problem.
appropriate function, rather than doing a horse-and-buggy
acquire. They now take the mutex type as an arg and can be
used with sleep as well as spin mutexes.
clients have been fixed. (So far as I can tell, all of the user-land
clients of <sys/select.h> do so vacuously, in the expectation that select()
might be declared there.)
SIGXCPU signal, and killing of processes that exceed their allowed run
time until they can play nice with sched_lock. Right now they are just
potentital panics waiting to happen. The printf() has bitten several
people.
not hold sched_lock while calling ttyprintf(). If we are on a serial
console, then ttyprintf() will end up getting the sio lock, resulting in
a lock order violation.

if_vr: handle the case where vr_encap() returns failure: bust out of the
packet sending loop instead of panicking. Also add some missing
newlines to some printf()s.
if_dc: The miibus_read and miibus_write methods keep swapping in and
out of MII mode by fiddling with CSR6 for cards with MII PHYs.
This is a hack to support the original Macronix 98713 card which
has built-in NWAY that uses an MII-like management interface
even though it uses serial transceivers. Conditionalize this
so that we only do this on 98713 chips, since it does bad things
to genuine tulip chips (and maybe other clones).
{kernel,modules}-reinstall.debug rather than {kernel,modules}-reinstall.
Otherwise, the '.debug' portion of the target is lost, and you end up
reinstalling the non debug version instead of the debug version.
