873a0bd675 Make the __bitcount*() functions unconditionally available, by moving
them out of the #if _BSD_VISIBLE block.  Other headers may depend on
__bitcount().  The dependencies can be a header not specified by
POSIX, and then namespace restrictions by _XOPEN_SOURCE are not
applicable, as it was reported.  Or, we might grow an implementation
of some POSIX facility using __bitcount(), which also should work.

74d7b9a832 * Add 11n HT40 support - i needed to send both HTINFO and HTCAP fields
in the join message so the firmware would pick it up.

* Strip out the direct hardware fiddling for 40MHz mode - the firmware
  we're using doesn't require it (the rtl8712su firmware does; it
  is less 'fullmac' than what we're using.)

* Fix the mbuf handling during errors - rsu_tx shouldn't free mbufs;
  it's up to the caller to do so.  This brings it in line with
  what other drivers do or should be doing.

Tested:

* RTL8712, HT40 channel, STA mode (during this commit)

9f86aba61c Exploit r288122 to address a cosmetic issue. Since PV chunk pages don't
belong to a vm object, they can't be paged out.  Since they can't be paged
out, they are never enqueued in a paging queue.  Nonetheless, passing
PQ_INACTIVE to vm_page_unwire() creates the appearance that these pages
are being enqueued in the inactive queue.  As of r288122, we can avoid
this false impression by passing PQ_NONE.

a9fcb51fbb Add an initial driver for the AR9170 series draft-11n hardware from
Atheros.

Thanks to OpenBSD for providing a driver based on the original
Atheros open source driver circa 2008.  This uses the early, pre-carl9170
atheros provided firmware.

It only supports 11bg at the moment.  I've not tested it with 11a
(and so the TX rate control logic may be slightly wrong!) so if
you do have the dual-band version of this hardware please do let me know.

Tested:

* AR9170, TP-Link WN821N 2GHz.

TODO:

* Hook this up to a non-module build.

b86fd7bcea Perform some rather amusing layering violations to add mbuf tags to the
net80211 receive path.  This allows drivers (notably USB right now, but
anything/everything!) to optionally defer bulk RX of 802.11 frames until
/outside/ of the driver lock(s), rather than doing:

UNLOCK(sc);
ieee80211_input*()
LOCK(sc);

.. which is really stupid.

The existing API is maintaned - if ieee80211_input() / ieee80211_input_all()
is called then the RSSI/NF values are used.  If the MIMO versions are called
with a given rx status pointer then it's used. Else, it'll use whatever
is in the RX mbuf tag.

c41b621878 Explicitly enable .MAKE.ALWAYS_PASS_JOB_QUEUE for bmake.
This is a NOP as r254419 enabled this by default in bmake.  Add it here though
to ensure it is known that we are using this as a default and in case a
bmake import removes the default we have.

This tells bmake to always pass job tokens into sub-commands.  Otherwise
it would only do so if the target being built depended on the special
.MAKE target (which causes _all_ commands to be executed with -n as well)
or if the command matches '${MAKE}/${.MAKE}/$(MAKE)/$(.MAKE)/make' (before
expansion, so ${LIB32WMAKE} would not qualify).  Using '+' on a command
(which runs the command with -n) would not pass the job token even though it
is a documented way to achieve the .MAKE effect on a command.

8012d6910c MFV r288063: make dataset property de-registration operation O(1)
A change to a property on a dataset must be propagated to its descendants
in case that property is inherited. For datasets whose information is
not currently loaded into memory (e.g. a snapshot that isn't currently
mounted), there is nothing to do; the property change will take effect
the next time that dataset is loaded. To handle updates to datasets that
are in-core, ZFS registers a callback entry for each property of each
loaded dataset with the dsl directory that holds that dataset. There
is a dsl directory associated with each live dataset that references
both the live dataset and any snapshots of the live dataset. A property
change is effected by doing a traversal of the tree of dsl directories
for a pool, starting at the directory sourcing the change, and invoking
these callbacks.

The current implementation both registers and de-registers properties
individually for each loaded dataset. While registration for a property is
O(1) (insert into a list), de-registration is O(n) (search list and then
remove). The 'n' for de-registration, however, is not limited to the size
(number of snapshots + 1) of the dsl directory. The eviction portion
of the life cycle for the in core state of datasets is asynchronous,
which allows multiple copies of the dataset information to be in-core
at once. Only one of these copies is active at any time with the rest
going through tear down processing, but all copies contribute to the
cost of performing a dsl_prop_unregister().

One way to create multiple, in-flight copies of dataset information
is by performing "zfs list" operations from multiple threads
concurrently. In-core dataset information is loaded on demand and then
evicted when reference counts drops to zero. For datasets that are not
mounted, there is no persistent reference count to keep them resident.
So, a list operation will load them, compute the information required to
do the list operation, and then evict them. When performing this operation
from multiple threads it is possible that some of the in-core dataset
information will be reused, but also possible to lose the race and load
the dataset again, even while the same information is being torn down.

Compounding the performance issue further is a change made for illumos
issue 5056 which made dataset eviction single threaded. In environments
using automation to manage ZFS datasets, it is now possible to create
enough of a backlog of dataset evictions to consume excessive amounts
of kernel memory and to bog down the system.

The fix employed here is to make property de-registration O(1). With this
change in place, it is hoped that a single thread is more than sufficient
to handle eviction processing. If it isn't, the problem can be solved
by increasing the number of threads devoted to the eviction taskq.

    Associate dsl property callback records with both the
    dsl directory and the dsl dataset that is registering the
    callback. Both connections are protected by the dsl directory's
    "dd_lock".

    When linking callbacks into a dsl directory, group them by
    the property type. This helps reduce the space penalty for the
    double association (the property name pointer is stored once
    per dsl_dir instead of in each record) and reduces the number of
    strcmp() calls required to do callback processing when updating
    a single property. Property types are stored in a linked list
    since currently ZFS registers a maximum of 10 property types
    for each dataset.

    Note that the property buckets/records associated with a dsl
    directory are created on demand, but only freed when the dsl
    directory is freed. Given the static nature of property types
    and their small number, there is no benefit to freeing the few
    bytes of memory used to represent the property record earlier.
    When a property record becomes empty, the dsl directory is either
    going to become unreferenced a little later in this thread of
    execution, or there is a high chance that another dataset is
    going to be loaded that would recreate the bucket anyway.

    Replace dsl_prop_unregister() with dsl_prop_unregister_all().
    All callers of dsl_prop_unregister() are trying to remove
    all property registrations for a given dsl dataset anyway. By
    changing the API, we can avoid doing any lookups of callbacks
    by property type and just traverse the list of all callbacks
    for the dataset and free each one.
