install now complains about ttyu0/ttyu1 not existing at boot time.
Since users wanting the uart based devices as terminals will need
to do something special to get them anyway set it up so a default
config doesn't complain.

that is no longer required. (In fact, it is not clear that it was ever
required in HEAD or RELENG_4, only RELENG_3 required a work-around.) Now,
as before revision 1.251, if the preexisting PTE is invalid, pmap_enter()
does not call pmap_invalidate_page() to update the TLB(s).
Note: Even with this change, the handling of a copy-on-write fault is
inefficient, in such cases pmap_enter() calls pmap_invalidate_page() twice.

might result in a deadlock. The fix involves critical changes in the PF
locking strategy (which will happen after 5.3R). For now advise users to set
debug.mpsafenet=0 if they use this kind of filtering.
The same problem exists for IPFW.

need to mask off the page offset bits. (This operation made some sense
prior to i386/i386/pmap.c revision 1.254 when we passed a physical address
rather than a vm_page pointer to pmap_enter().)
Discussed extensively with KAME. The API author's intent isn't clear at this
point, so rather than remove the code entirely, #if 0 out and put a big
comment in for now. The IPV6_RECVPATHMTU sockopt is available if the
application wants to be notified of the path MTU to optimize packet sizes.
Thanks to JINMEI Tatuya <jinmei@isl.rdc.toshiba.co.jp> for putting up
with my incessant badgering on this issue, and fenner for pointing out
the API issue and suggesting solutions.
data endpoints. The control endpoint doesn't need read/write/poll
operations, and more importantly, the thread counts should be
separate so that the control endpoint can properly reference itself
while deleting and recreating the data endpoints.
* Add some macros that handle referencing/releasing devices, and use them
for sleeping/woken-up and open/close operations as apppropriate.
* Use d_purge for FreeBSD, and a loop testing the open status for all
the endpoints for NetBSD and OpenBSD, so that when the device is
detached, the right thing always happens.
