end, make pmap_invalidate_all() global and have it only handle the
local CPU -- i.e. no rendezvous. We do not use pmap_invalidate_all
other than during initialization.
Note that the BSP already purges its TC -- it was missing for APs
only. Nonetheless, this so far seems to eliminate random problems.
ia64_probe_sapics(), we also create PCPU structures for any Local SAPICs
we encounter. When SMP is disabled, this leaves us with partially setup
PCPU structures, which typically results in panics when we're iterating
over CPUs. When SMP is disabled, we now prevent the creation of the
PCPU structures.
Unexpand the tag, remove the fbsd:nokeywords property and add the
svn:keywords property. This should eliminate the gratuituous diffs
that appear on these files in projects branches.

and ordering related variables, fields and locks next to each
other. Add more comments to variables.
Over time 'ifnet' has accumlated a lot of additional pointers and
functionality in an unstructured way making it quite hard to read
and understand while obfuscating relationships between fields and
variables.
Quantify the structure size and how bloated it has become.
This is only a mechanical change in preparation for upcoming
work to make ifnet opaque to drivers and to separate out the
interface queuing.

CDC=0 simply means "no command codes", CDC=1 means "AT command codes."
There's no driver change required! It's purely to tell the application
layer whether to speak AT commands or not. Things are all still serial.

threaded handlers.
It's not easy to see from the diffs of this change exactly how it
accomplishes the above. The arm_mask_irq() and arm_unmask_irq() functions
are, respectively, the pre_thread and post_thread hooks. Not seen in
these diffs, the arm_post_filter() routine also EOIs. The post_filter
routine runs after filter handlers if there will be no threaded handlers,
so it just EOIs. The pre_thread routine masks the interrupt (at the
controller, not the source) and EOIs. So one way or another, the EOI
happens at the point where filter handlers are done.

the interrupt handler. If the event callback starts a new short timeout,
the timer can fire before returning from the event callback, and clearing
the interrupt status after that loses the interrupt and hangs until the
counter wraps. Fixing all of this removes the need for the do-nothing
loop at the top of the handler which really just waited for the counter to
roll over and reach the one-shot count again.
Also add a missing return(0) in the periodic timer start case.
For now, the AMRR code only knows about _either_ MCS or non-MCS rates.
It doesn't know how to downgrade (ie, doing 11b CCK rates if MCS0 isn't
reliable.)

If job control is not enabled, background jobs started with ... & ignore
SIGINT and SIGQUIT so that they are not affected by such signals that are

reassigning a different action for these signals (as if the shell invocation
inherited these signal actions from its parent).
