Default to use 10 seconds as nap interval instead of 1.
Previously, we have a nap interval of 1 second while we have a timeout of
128 seconds by default, which could be an overkill, and for some hardware
the patting action may be expensive.
Note that the choice of nap interval is still arbitrary. We preferred
a safe value where even when the system is very heavily loaded, the
watchdog should not shoot the system down if it's not really hung.
According to the manual page of Linux's watchdog daemon, the nap interval
time of theirs is 10 seconds, which seems to be a reasonable value --
according to Intel documentation AP-725 (Document Number: 292273-001),
ICH5's maximum timeout is about 37.5 seconds, which the ichwd(4) driver
would set when we requested 128 seconds (although it should probably
feed back this as an error and do not set the timeout). Since that's
the shortest maximum value, 10 seconds seems to be a right choice for
us too.

prevent doing filter ops locking for staticly compiled filter ops...
This significantly reduces lock contention when adding/removing knotes
on busy multi-kq system... Next step is to cache these references per
kq.. i.e. kq refs it once and keeps a local ref count so that the same
refs don't get accessed by many cpus...
only allocate a knote when we might use it...
Add a new flag, _FORCEONESHOT.. This allows a thread to force the
delivery of another event in a safe manner, say waking up an idle http

Changes affecting current and future time stamps
Turks & Caicos' switch from US eastern time to UTC-4 year-round
did not occur on 2014-11-02 at 02:00. It's currently scheduled
for 2015-11-01 at 02:00. (Thanks to Chris Walton.)
Changes affecting past time stamps
Many pre-1989 time stamps have been corrected for Asia/Seoul and
Asia/Pyongyang, based on sources for the Korean-language Wikipedia
entry for time in Korea. (Thanks to Sanghyuk Jung.) Also, no
longer guess that Pyongyang mimicked Seoul time after World War II,
as this is politically implausible.
Some more zones have been turned into links, when they differed
from existing zones only for older time stamps. As usual,
these changes affect UTC offsets in pre-1970 time stamps only.
Their old contents have been moved to the 'backzone' file.
The affected zones are: Africa/Addis_Ababa, Africa/Asmara,
Africa/Dar_es_Salaam, Africa/Djibouti, Africa/Kampala,
Africa/Mogadishu, Indian/Antananarivo, Indian/Comoro, and
Indian/Mayotte.
Changes affecting commentary
The commentary is less enthusiastic about Shanks as a source,
and is more careful to distinguish UT from UTC.

Enable the use of VM_PHYSSEG_SPARSE on amd64 and i386, making it the default

kernel page table pages allocated during pmap_bootstrap() but those vm_page

lacp_linkstate goes looking for the current ifmedia on a link state

unplug followed by replug. The fix is to process module events before
link-state events within the driver, and to always rebuild the ifmedia

Pull in r221709 from upstream llvm trunk (by Frédéric Riss):
Totally forget deallocated SDNodes in SDDbgInfo.
What would happen before that commit is that the SDDbgValues associated with
a deallocated SDNode would be marked Invalidated, but SDDbgInfo would keep
a map entry keyed by the SDNode pointer pointing to this list of invalidated
SDDbgNodes. As the memory gets reused, the list might get wrongly associated
with another new SDNode. As the SDDbgValues are cloned when they are transfered,
this can lead to an exponential number of SDDbgValues being produced during
DAGCombine like in http://llvm.org/bugs/show_bug.cgi?id=20893
Note that the previous behavior wasn't really buggy as the invalidation made
sure that the SDDbgValues won't be used. This commit can be considered a
memory optimization and as such is really hard to validate in a unit-test.
This should fix abnormally large memory usage and resulting OOM crashes
when compiling certain ports with debug information.
