* Add the relevant RX filter entry for MYBEACON.
Tested:
* AR5416, STA
* AR9285, STA
TODO:
* once the code is in -HEAD, just make sure that the code which uses it
correctly sets BEACON for pre-AR5416 chips.

This fires off an interrupt if the TSF from the AP / IBSS peer is
wildly out of range. I'll add some code to the ath(4) driver soon
which makes use of this.

to the hardware.
The QCA HAL has a comment noting that if this isn't done, modifications
to AR_IMR_S2 before AR_IMR is flushed may produce spurious interrupts.

Flushing the caches is required before doing a panic dump, but ARM
doesn't provide a flavor of flush that gets broadcast to other cores.
However, all cores except one are stopped before doing a dump, so this
works around the lack of a global flush/invalidate by doing it locally
on each CPU as part of stopping.

This was added ca. 2004 for the purpose of ensuring the caches were in the
right state after the debugger set a breakpoint. kdb_cpu_sync_icache()
was added in 2007 to handle that situation, and now the wbinv_all is
actually harmful because the operation isn't broadcast to other cores.
* memory is now allocated as early as possible, without holding locks.
* sysctl users are now guaranteed to get a response (M_WAITOK buffer prealloc).
* socket users are more likely to use on-stack buffer for replies.
* standard kernel malloc/free functions are now used instead of radix wrappers.
rt_msg2() has been renamed to rtsock_msg_buffer().

#gpio-cells property.
Add a new ofw_bus method (OFW_BUS_MAP_GPIOS()) that allows the GPIO
controller to implement its own mapping to deal with gpio-specifiers,
allowing the decoding of gpio-specifiers to be controller specific.
The default ofw_bus_map_gpios() decodes the linux standard (#gpio-cells =
<2>) and the FreeBSD standard (#gpio-cells = <3>).
It pass the gpio-specifier flag field to the children as an ivar variable so
they can act upon.
checks for special pcid values in invlpg_pcid_handler(). Forst check
for special values, and only then do PCID-specific page invalidation.
Minor fix to the style compliance, declare local variable at the
function start.

entry and performs the upgrade of the entry permissions from read-only
to read-write, we must allow to search for the source pages in the
backing object, like we do in the case of forking the read-only wired
entry. For the fork case, the behaviour is allowed by src_readonly
boolean, which in fact is only used to assert that read-write case
provides all source pages in the top-level object.
Eliminate the src_readonly variable. Allow for the copy loop to look
into the backing objects, add explicit asserts to ensure that only
read-only and upgrade case actually does.
Expand comments. Change the panic call into assert.

Equivalent functionality in GENERIC requires making vt(9) the default console
driver, which is probably appropriate at this point.
using armv7_idcache_wbinv_all, because wbinv_all doesn't broadcast the
operation to other cores. In elf_cpu_load_file() use icache_sync_all()
and explain why it's needed (and why other sync operations aren't).
As part of doing this, all callers of cpu_icache_sync_all() were
inspected to ensure they weren't relying on the old side effect of
doing a wbinv_all along with the icache work.
RTM_CHANGE is now handled inside route.c:rtrequest1_fib() as it should be.
Note change change handler is a separate function rtrequest1_fib_change().

one userland tool that still looks at the kern.smp.active sysctl, so
preserve it but point it to smp_started as well.

define a few imx_ccm_foo() functions that are implemented by the imx51 or
imx6 ccm code. Of course, the imx6 ccm code is still more a wish than
reality, so for now its implementations just return hard-coded numbers.

The resulting image is installed to /boot/boot1.efifat. If dd'ed to an 800K
