MIPS does not use the common _rtld_bind() to handle runtime binding.
Instead, it uses a private _mips_rtld_bind(). Update _mips_rtld_bind()
to include the changes made to _rtld_bind() in r216695 and r218476 to
support upgrading the read-locked rtld_bind_lock to a write lock when
an object with a filter is encountered.
While here, add a 'where' variable to track the location of the fixup
in the GOT to make the code flow more closely match _rtld_bind().

The size can be changed by side effect of modifying kern.maxvnodes.
Since numbucketlocks was not modified, setting a sufficiently low value
would give more locks than actual buckets, which would then lead to
corruption.
Force the number of buckets to be not smaller.
Note this should not matter for real world cases.

UEXT are Universal EXTension connector from Olimex. They embed i2c, spi
and uart pins along power in one connector and are found on most,
if not all, Olimex boards.
The Olimex A20 SOM EVB have two UEXT connector so enable the nodes found on
those two connectors.
Patch has been applied upstream, in the meantime add the nodes to our custom
DTS.
The swap pager enqueues laundered pages near the head of the inactive queue
to avoid another trip through LRU before reclamation. This change adds
support for this behaviour to the vnode pager and makes use of it in UFS and
ext2fs. Some ioflag handling is consolidated into a common subroutine so
that this support can be easily extended to other filesystems which make use
of the buffer cache. No changes are needed for ZFS since its putpages
routine always undirties the pages before returning, and the laundry
thread requeues the pages appropriately in this case.

It allows one to trivially convert an absolute path to a relative path
and the reverse. The test programs themselves are very useful in scripts
but the real use comes shortly with the -r and -a arguments to ln.
These are sometimes known as the --relative and --absolute flags and
can force a symlink to be relative when you only have an absolue path.
Another place these are sometimes used is to add -a and -r args to 'realpath'.
Incredibly useful in Makefiles.
I was going to just add the files in with 'ln' but a library makes more sense.
The test programs may come out in their own right some day for scripting.

The kernel always copies an entire struct ifreq and IPv4 addresses will
always fit in an ifreq.
On systems with pointers larger than 64-bits, the computed size will be
less than the size of struct ifreq, potentially resulting in the kernel
attempting to copyin memory from outside the allocation.

This just stores pointers to the IE; it doesn't yet parse anything.
Note: it blows out the size of ieee80211_node, so this will require
ye olde kernel/modules recompile.
* Obey the peer A-MPDU density if it's larger than the currently configured
one.
* Pay attention to the peer A-MPDU max-size and don't assume we can transmit
a full A-MPDU (64k!) if the peer announces smaller values.
Relnotes: ath(4): Fix A-MPDU transmit; obey A-MPDU density and max size.
* Pepper comments around which describe what state(s) we're in when faking
up 11n nodes.
* By default don't fake it up as 11n until we properly negotiate the 11n
capabilities using probe request/response frames.
* Send a probe request with our HT information, as the 802.11-2012 spec
suggests.
* Reassociate with the driver if we've been promoted.
This is done because although learning a peer via beacons can learn 11n
state, learning peers via hearing probe frames and broadcast frames
does not. Thus, sometimes you end up with an 11n peer in the peer
table and sometimes you don't.
Note that the probe request/response exchange may not actually succeed.
Ideally we'd put the peer into some blocking state until we've exchanged
probe request/reponse to learn capabilities, or we timeout and just
stay non-11n.
This is more an experiment to get 11n IBSS nodes actually discovering
each other and be able to transmit. There are other issues that creep
up which I'll attempt to address in future commits.
Tested:
* AR9380 NICs in 11n mode.

The default pkg(8) from pkg.freebsd.org requires libjail.so,
so mark the jail package as vital along with the runtime
package to avoid errors when libjail.so is removed. This is
a no-op for systems with WITHOUT_JAIL in src.conf(5) and pkg(8)
built from the Ports Collection.
In order to make this work without marking packages such as
the jail-lib32, for example, the jail.ucl file needed to be
split out into separate files similarly to the runtime-*.ucl
files.
