This initial DFS module provides basic functionality to deal
with radar pulses reported by the Atheros DFS HW pulse detector.
The reported data is evaluated and basic plausibility checks
are performed to filter false pulses. Passing radar pulses are
forwarded to pattern detectors which are not yet implemented.
(Some modifications to actually use ATH9K_DFS_DEBUGFS based on comments
from Julian Calaby <julian.calaby@gmail.com>. -- JWL)

In ai_attach(), space is allocated for an si_info struct. Immediately
after the allocation, routine ai_doattach() is called and that allocated

Instead of releasing and taking back the lock over and over again in the

This makes locking much easier to review and should not have any noticeable

This fixes an odd bug found on a Dell PowerEdge 1850/0RC130
(BIOS A05 01/09/2006) where all of the modules doing pci_set_dma_mask
would fail with:
ata_piix 0000:00:1f.1: enabling device (0005 -> 0007)
ata_piix 0000:00:1f.1: can't derive routing for PCI INT A
ata_piix 0000:00:1f.1: BMDMA: failed to set dma mask, falling back to PIO
The issue was the Xen-SWIOTLB was allocated such as that the end of
buffer was stradling a page (and also above 4GB). The fix was
spotted by Kalev Leonid which was to piggyback on git commit
e79f86b2ef9c0a8c47225217c1018b7d3d90101c "swiotlb: Use page alignment
for early buffer allocation" which:
We could call free_bootmem_late() if swiotlb is not used, and
it will shrink to page alignment.
So alloc them with page alignment at first, to avoid lose two pages
And doing that fixes the outstanding issue.

We need to set the extended radio parameters for wl127x only.
Currently, we were only calling this command with wl127x STA mode, but
we should also do it for AP mode.

and use a single if for the chip type to do everything at once.

We should not get an hlid value bigger than WL12XX_MAX_LINKS from
wl1271_rx_handle_data(). We have a WARN_ON in case it happens. But
despite the warning, we would still go ahead and write the hlid bit
into active_hlids (a stack variable). This would cause us to
overwrite other data in the stack.
To avoid this problem, we now skip the write when issuing the warning,
so at least we don't corrupt data.

skb priority
Use DCB notifiers to set the skb priority to allow packets
to be steered and tagged correctly over DCB enabled drivers
that setup traffic classes.
This allows queue_mapping() routines to be removed in these

All sysdev classes and sysdev devices will converted to regular devices
and buses to properly hook userspace into the event processing.
There is no interesting difference between a 'sysdev' and 'device' which
would justify to roll an entire own subsystem with different userspace
export semantics. Userspace relies on events and generic sysfs subsystem
infrastructure from sysdev devices, which are currently not properly
available.
Every converted sysdev class will create a regular device with the class
name in /sys/devices/system and all registered devices will becom a children
of theses devices.
For compatibility reasons, the sysdev class-wide attributes are created
at this parent device. (Do not copy that logic for anything new, subsystem-
wide properties belong to the subsystem, not to some fake parent device
created in /sys/devices.)
Every sysdev driver is implemented as a simple subsystem interface now,
and no longer called a driver.
After all sysdev classes are ported to regular driver core entities, the
sysdev implementation will be entirely removed from the kernel.

cfg_workqueue was added to notify cfg80211 that scan, connect
or disconnect is done by calling respective completion handlers.
We can avoid use of this workqueue by calling those handlers
from other places.
1) Call connect, disconnect completion handlers in their callback
functions.
ex. Call cfg80211_connect_result() in mwifiex_cfg80211_connect()
2) Call scan completion handler after parsing response of last scan
command in a queue.
After removing the workqueue, variables (assoc_request etc.) and
checks used for mutual exclusion become redundant. Those are also
removed in this patch.
