taskqueue_enqueue() was changed to support both fast and non-fast
taskqueues 10 years ago in r154167. It has been a compat shim ever
since. It's time for the compat shim to go.

is the physical memory size so may be larger than a u_long can hold, e.g.
on ARM with LPAE we could see an address space of up to 40 bits. On ARM
u_long is only 32 bits so the memory size will be truncated, possibly to
zero.

Note that isrc_arg member of struct intr_irqsrc is used only for
INTR_SOLO and IPI filter. This should be remembered if IPI filters
and their arguments will be stored on another place.
This option could be unusable very soon, if interrupt controllers
implementations will not be implemented considering it.
Enable system register access for EL2. Alpine-V2 is
the first device requiring this to be enabled.
It is also in-sync with Linux initialization code,
and compatible with Alpine-V2 uboot requirements.

Some MPC85xx GPIO controllers are compatible with QorIQ.
It may make more sense in the future to rename this and mpc85xx_gpio.c, as
mpc85xx_gpio.c appears to only be compatible with a few mpc85xx SoCs. All other
MPC85xx SoCs use the same controller as QorIQ.
Summary:
As part of the migration of rman_res_t to be typed to uintmax_t, memory ranges
must be clamped appropriately for the bus, to prevent completely bogus addresses
from being used.

These firmwares were obtained from the beta "Chelsio T5/T4 Unified Wire
v2.12.0.2 for Linux" release. Changes since last release are listed in the
"Release Notes" accompanying the beta release and are copy-pasted here as well.
The plan is to have only GA'd firmwares in any -STABLE FreeBSD branch so I'll
MFC this (after 2 months) only if it ends up in a GA release.

The m_ext.ext_cnt pointer becomes a union. It can now hold the refcount
value itself. To tell that m_ext.ext_flags flag EXT_FLAG_EMBREF is used.
The first mbuf to attach a cluster stores the refcount. The further mbufs
to reference the cluster point at refcount in the first mbuf. The first
mbuf is freed only when the last reference is freed.
The benefit over refcounts stored in separate slabs is that now refcounts
of different, unrelated mbufs do not share a cache line.
For EXT_EXTREF mbufs the zone_ext_refcnt is no longer needed, and m_extadd()
becomes void, making widely used M_EXTADD macro safe.
For EXT_SFBUF mbufs the sf_ext_ref() is removed, which was an optimization
exactly against the cache aliasing problem with regular refcounting.

Drivers should set their own filters via ic_scan_start()/ic_scan_end()
callbacks; and we don't need frames other than beacons or probe responses.
(Note: this was a noop since r287197 due to promiscuous mode with bridge
workaround)

- In case, when we are doing <smth> -> INIT (FEXT_REINIT) -> <smth2>
state transition, cancel_scan() may be called in the first transition.
Reenqueue second state transition, so things will be executed in order.
- Discard any AUTH+ state transition request when INIT -> SCAN
transition is not done.
- Allow to track discarded state transitions via 'state' debugging
category.

scan_curchan_task() functions)
(This part should fix the problem, described in
https://lists.freebsd.org/pipermail/freebsd-wireless/2016-January/006420.html)
- Rename ss_scan_task into ss_scan_start (better describes it's
current purpose)
- Utilize taskqueue_*_timeout() functions instead of current mechanism:
* reschedule scan_curchan_task() via taskqueue_enqueue_timeout()
for every 'maxdwell' msecs (will replace infinite loop + sleeping
for 'maxdwell' period via cv_wait());
* rerun the task immediately when an external event occurs
(instead of waking it up via cv_signal())
Also, use mtx_sleep() to wait for null frame transmission
(allows to drop conditional variable).

* Intel 3945BG, STA mode;
* RTL8188EU, STA mode.
