a hard hang due to an interrupt storm or stuck interrupt pin. We
return the next IRQ that is larger than the last one returned and
in doing so give all interrupts a fair chance of being handled.
Consequently, we're able to break into the kernel debugger in such

cannot eliminate. While timing does not have to be perfect, the
loops must be there to have at least some notion of delay.

kern_yield(curthread->td_user_pri). The function remains
undocumented.

- entirely eliminate some calls to uio_yeild() as being unnecessary,
such as in a sysctl handler.
- move should_yield() and maybe_yield() to kern_synch.c and move the
prototypes from sys/uio.h to sys/proc.h
- add a slightly more generic kern_yield() that can replace the
functionality of uio_yield().
- replace source uses of uio_yield() with the functional equivalent,
or in some cases do not change the thread priority when switching.
- fix a logic inversion bug in vlrureclaim(), pointed out by bde@.
- instead of using the per-cpu last switched ticks, use a per thread
variable for should_yield(). With PREEMPTION, the only reasonable
use of this is to determine if a lock has been held a long time and
relinquish it. Without PREEMPTION, this is essentially the same as
the per-cpu variable.

This fixes two problems -
* All packets need to be processed here, not just aggregate ones - as any
received frames (AMPDU or otherwise) in the given TID (traffic class id)
will update the sequence number and, implied with that, update the window;
* It seems there's situations where packets aren't matching a current node but
somehow need to be tracked. Thus just tag them all for now; I'll figure out
the why later.
Whilst I'm here, bump the stats counters whilst I'm at it.
This fixes AMPDU RX in my tests; the main problems now stem from what look
like PHY level error/retransmits which are impeding general throughput, incl.
AMPDU.
In the dec.2009 rewrite I introduced a bug, using for the
computation the arrival time instead of the time the packet
has exited from the queue.
The bandwidth computation was still correct because it is
computed elsewhere, but traffic was sent out in bursts.
The bug is also present in RELENG_8 after dec.2009

I am setting both to i386 since this is what picobsd is used for,
though there might be a better fix.
Add initial support for parallel make. This is disabled right now,
because there are incorrect dependencies somewhere which require
