- Do not check for a specific physical function (PF) before claiming a device.
Different PFs have different device-ids so this check is redundant anyway.
- Obtain the PF# from the WHOAMI register instead of pci_get_function().
- Setup the memory windows using the real BAR0 address, not what the VM says it
is.

the assumption that ath_softc doesn't change size based on build time
configuration.
I picked up on this because suddenly radar stuff didn't work; and
although the ath_dfs code was setting sc_dodfs=1, the main ath driver
saw sc_dodfs=0.
So for now, include opt_ath.h in driver source files. This seems like
the sane thing to do anyway.
I'll have to do a pass over the code at some later stage and turn
the radiotap TX/RX structs into malloc'ed memory, rather than in-line
inside of ath_softc. I'd rather like to keep ath_softc the same
layout regardless of configuration parameters.

When building libelf in the bootstrap stage this would include the tree
versions of, for example, sys/_types.h. This would work as long as the
tree's version of this file was close enough to the system's version of
the file. If, however, there was a change in the tree such that the location
of a typedef was moved this would cause problems. In this case the version
of sys/_types.h in the tree no longer defines __wchar_t and expects it to
to be defined in machine/_types.h, however we pick up machine/_types.h from
the system and find it is not defined there. The solution is to restrict the
parts of sys er include from the tree to those that are needed.
This fixes the recent Tinderbox failure.

a buffer pointer.
For large radar pulses, the AR9130 and later will return a series of
FFT results for software processing. These can overflow a single 2KB
buffer on longer pulses. This would result in undefined buffer behaviour.
This includes a few new fields in each RXed frame:
* per chain RX RSSI (ctl and ext);
* current RX chainmask;
* EVM information;
* PHY error code;
* basic RX status bits (CRC error, PHY error, etc).
This is primarily to allow me to do some userland PHY error processing
for radar and spectral scan data. However since EVM and per-chain RSSI
is provided, others may find it useful for a variety of tasks.
The default is to not compile in the radiotap vendor extensions, primarily
because tcpdump doesn't seem to handle the particular vendor extension
layout I'm using, and I'd rather not break existing code out there that
may be (badly) parsing the radiotap data.
Instead, add the option 'ATH_ENABLE_RADIOTAP_VENDOR_EXT' to your kernel
configuration file to enable these options.
and the CRC error bits set. The radar payload is correct.
When this happens, the stack doesn't see them PHY error frames and
isn't interpreted as a PHY error. So, no radar detection and no radiotap
PHY error handling.
Now, this may introduce some weird issues if the MAC sends up some other
combination of CRC error + PHY error frames; this commit would break that
and mark them as PHY errors instead of CRC errors.
I may tinker with this a little more to pass radar/early radar/spectral
frames up as PHY errors if the CRC bit is set, to restore the previous
behaviour (where if CRC is set on a PHY error frame, it's marked as a CRC
error rather than PHY error.)
Tested on: AR5416, over the air, to a USRP N200 which is generating a
large number of a variety of radar pulses.

a da(4) instance going away while GEOM is still probing it.
In this case, the GEOM disk class instance has been created by
disk_create(), and the taste of the disk is queued in the GEOM
event queue.
While that event is queued, the da(4) instance goes away. When the
open call comes into the da(4) driver, it dereferences the freed
(but non-NULL) peripheral pointer provided by GEOM, which results
in a panic.
The solution is to add a callback to the GEOM disk code that is
called when all of its resources are cleaned up. This is
implemented inside GEOM by adding an optional callback that is
called when all consumers have detached from a provider, and the
provider is about to be deleted.
scsi_cd.c,
scsi_da.c: In the register routine for the cd(4) and da(4)
routines, acquire a reference to the CAM peripheral
instance just before we call disk_create().
Use the new GEOM disk d_gone() callback to register
a callback (dadiskgonecb()/cddiskgonecb()) that
decrements the peripheral reference count once GEOM
has finished cleaning up its resources.
In the cd(4) driver, clean up open and close
behavior slightly. GEOM makes sure we only get one
open() and one close call, so there is no need to
set an open flag and decrement the reference count
if we are not the first open.
In the cd(4) driver, use cam_periph_release_locked()
in a couple of error scenarios to avoid extra mutex
calls.
geom.h: Add a new, optional, providergone callback that
is called when a provider is about to be deleted.
geom_disk.h: Add a new d_gone() callback to the GEOM disk
interface.
Bump the DISK_VERSION to version 2. This probably
should have been done after a couple of previous
changes, especially the addition of the d_getattr()
callback.
geom_disk.c: Add a providergone callback for the disk class,
g_disk_providergone(), that calls the user's
d_gone() callback if it exists.
Bump the DISK_VERSION to 2.
geom_subr.c: In g_destroy_provider(), call the providergone
callback if it has been provided.
In g_new_geomf(), propagate the class's
providergone callback to the new geom instance.
blkfront.c: Callers of disk_create() are supposed to pass in
DISK_VERSION, not an explicit disk API version
number. Update the blkfront driver to do that.
disk.9: Update the disk(9) man page to include information
on the new d_gone() callback, as well as the
previously added d_getattr() callback, d_descr
field, and HBA PCI ID fields.

This is required for ARM EABI. Section 7.1.1 of the Procedure Call for the
ARM Architecture (AAPCS) defines wchar_t as either an unsigned int or an
unsigned short with the former preferred.
Because of this requirement we need to move the definition of __wchar_t to
a machine dependent header. It also cleans up the macros defining the limits
of wchar_t by defining __WCHAR_MIN and __WCHAR_MAX in the same machine
dependent header then using them to define WCHAR_MIN and WCHAR_MAX
respectively.

to add PV list locking to pmap_pv_demote_pde(), it is necessary to change
the way that pmap_pv_demote_pde() allocates PV entries. Specifically,
once pmap_pv_demote_pde() begins modifying the PV lists, it can't allocate
any new PV chunks, because that could require the PV list lock to be
dropped. So, all necessary PV chunks must be allocated in advance. To my
surprise, this new approach is a few percent faster than the old one.
