If an ASCONF chunk is outstanding, then the following ASCONF
chunk will be queued for later transmission. But when we free
the asoc, we forget to free the ASCONF queue at the same time,
this will cause memory leak.

Some stack variables (name *ssid and *channel) are only used to define
the size of the memory block that needs to be allocated for the
request structure in the nl80211_trigger_scan() and
nl80211_start_sched_scan() functions.
This is unnecessary because the sizes of the actual elements in the
structure can be used instead.

simplify mesh locking) mesh table allocation is performed with the
pathtbl_resize_lock taken. Under those conditions one should not sleep.

This adds a new generic gpio rfkill driver to support rfkill switches
which are controlled by gpios. The driver also supports passing in
data about the clock for the radio, so that when rfkill is blocking,
it can disable the clock.
This driver assumes platform data is passed from the board files to
configure it for specific devices.

In ad-hoc mode, beacon timers are configured differently compared to AP
mode, and (depending on the scenario) can vary enough to make the beacon
tasklet not detect slot 0 based on the TSF.
Since staggered beacons are not (and cannot be) used in ad-hoc mode, it
makes more sense to just hardcode slot 0 here, avoiding unnecessary
TSF reads and calculations.

cfg80211 scan code adds separate BSS entries if the same BSS shows up
on multiple channels. However, sme implementation does not use the
frequency when fetching the BSS entry. Fix this by adding channel
information to cfg80211_roamed() and include it in cfg80211_get_bss()
calls.
Please note that drivers using cfg80211_roamed() need to be modified to
fully implement this fix. This commit includes only minimal changes to
avoid compilation issues; it maintains the old (broken) behavior for
most drivers. ath6kl was the only one that I could test, so I updated
it to provide the operating frequency in the roamed event.

This adds proper RCU annotations to the mesh path
table code, and fixes a number of bugs in the code
that I found while checking the sparse warnings I
got as a result of the annotations.
Some things like the changes in mesh_path_add() or
mesh_pathtbl_init() only serve to shut up sparse,
but other changes like the changes surrounding the
for_each_mesh_entry() macro fix real RCU bugs in
the code.

The locking in mesh_{mpath,mpp}_table_grow not only
has an rcu_read_unlock() missing, it's also racy
(though really only technically since it's invoked
from a single function only) since it obtains the
new size of the table without any locking, so two
invocations of the function could attempt the same
resize.
Additionally, it uses synchronize_rcu() which is
rather expensive and can be avoided trivially here.
Modify the functions to only use the table lock
and use call_rcu() instead of synchronize_rcu().

mac80211 uses call_rcu() with functions that are
defined in the module, so it must use rcu_barrier()
at module exit time.
Luckily, this seems to not be a problem in practice
as module unload and unregistration takes a long
time and probably does multiple synchronize_rcu().
