5aa7e8edc5 In selectroute() add a missing fibnum argument to an in6_rtalloc()
call in an #if 0 section.

In in6_selecthlim() optimize a case where in6p cannot be NULL due to an
earlier check.

More consistently use u_int instead of int for fibnum function arguments.

70e0b5ac20 Hold IF_LOCK when manipulating the interface flags.
It doesn't _really_ help all that much, I'll commit something to
sys/net/if.c at some point explaining why, but the lock should be held
when checking/manipulating/branching because of said lock.

dcc56af073 Although it's documented that the vap newstate call can drop the
comlock, I'd like to find and analyse these cases to see if they
really are valid.

074d80ac13 - Add support for Family 12h, 14h and 15h processors.
- Remove all attempts to guess physical temperature using DiodeOffset.
There are too many reports that it varies wildly depending on motherboard.
Instead, if it is known to scale well and its offset is known from other
temperature sensors on board, the user may set "dev.amdtemp.0.sensor_offset"
tunable to compensate the difference.  Document the caveats in amdtemp(4).
- Add a quirk for Socket AM2 Revision G processors.  These processors are
known to have a different offset according to Linux k8temp driver.
- Warn about Family 10h Erratum 319.  These processors have broken sensors.
- Report temperature in more logical orders under dev.amdtemp node.  For
example, "dev.amdtemp.0.sensor0.core0" is now "dev.amdtemp.0.core0.sensor0".
- Replace K8, K10 and K11 with official processor names in amdtemp(4).

84110e7e0b Account the writeable shared mappings backed by file in the vnode
v_writecount.  Keep the amount of the virtual address space used by
the mappings in the new vm_object un_pager.vnp.writemappings
counter. The vnode v_writecount is incremented when writemappings gets
non-zero value, and decremented when writemappings is returned to
zero.

Writeable shared vnode-backed mappings are accounted for in vm_mmap(),
and vm_map_insert() is instructed to set MAP_ENTRY_VN_WRITECNT flag on
the created map entry.  During deferred map entry deallocation,
vm_map_process_deferred() checks for MAP_ENTRY_VN_WRITECOUNT and
decrements writemappings for the vm object.

Now, the writeable mount cannot be demoted to read-only while
writeable shared mappings of the vnodes from the mount point
exist. Also, execve(2) fails for such files with ETXTBUSY, as it
should be.

bf3db8aa65 To improve control over the use of mount(8) inside a jail(8), introduce
a new jail parameter node with the following parameters:

allow.mount.devfs:
	allow mounting the devfs filesystem inside a jail

allow.mount.nullfs:
	allow mounting the nullfs filesystem inside a jail

Both parameters are disabled by default (equals the behavior before
devfs and nullfs in jails). Administrators have to explicitly allow
mounting devfs and nullfs for each jail. The value "-1" of the
devfs_ruleset parameter is removed in favor of the new allow setting.

7cfce7cec7 hrs@ reported a panic to freebsd-stable@ under the subject line
"panic in 8.3-PRERELEASE" on Feb. 22, 2012. This panic was caused
by use of a mix of tsleep() and msleep() calls on the same event
in the new NFS server DRC code. It did "mtx_unlock(); tsleep();"
in two places, which kib@ noted introduced a slight risk that the
wakeup() would occur before the tsleep(), resulting in a 10sec
delay before waking up. This patch fixes the problem by replacing
"mtx_unlock(); tsleep();" with mtx_sleep(..PDROP..). It also
changes a nfsmsleep() call to mtx_sleep() so that the code uses
mtx_sleep() consistently within the file.

I'm not sure _why_ the ic is NULL here, but I've seen it occasionally do
this after I've been tinkering with things for a while.  It ends up
crashing in a call to ath_chan_set() via the net80211 scan code and scan
