Rafał Miłecki 49083b47a3 b43: N-PHY: update generic rev7+ workarounds
Add some missing ops and prepare for new devices support. This patch is
a great stability improvement for BCM43217. Earlier Tenda W322E used to
disconnect every 2 minutes (16 times over 30 minutes). With this fix I
got it running for 4 hours (with iperf) without any disconnection.

Knowing radio params is quite important to provide help to users, so
print it even with debugging disabled.

Support for firmware rev 508+ was added years ago, but we never noticed
it reports channel in a different way for G-PHY devices. Instead of
offset from 2400 MHz it simply passes channel id (AKA hw_value).

So far it was (most probably) affecting monitor mode users only, but

The asyncronous firmware load uses a completion struct to hold firmware

however, a problem in that the waiter is nevered canceled during teardown.
As a result, unloading the driver when firmware is not available causes an oops.

In https://bugzilla.kernel.org/show_bug.cgi?id=67561, a locking dependency is reported
when b43 is used with hostapd, and rfkill is used to kill the radio output.

The lockdep splat (in part) is as follows:

======================================================
[ INFO: possible circular locking dependency detected ]
3.12.0 #1 Not tainted
-------------------------------------------------------
rfkill/10040 is trying to acquire lock:
 (rtnl_mutex){+.+.+.}, at: [<ffffffff8146f282>] rtnl_lock+0x12/0x20

but task is already holding lock:
 (rfkill_global_mutex){+.+.+.}, at: [<ffffffffa04832ca>] rfkill_fop_write+0x6a/0x170 [rfkill]

--snip--

Chain exists of:
  rtnl_mutex --> misc_mtx --> rfkill_global_mutex

The fix is to move the initialization of the hardware random number generator
outside the code range covered by the rtnl_mutex.

Linus Torvalds 8ceafbfa91 Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm
Pull DMA mask updates from Russell King:
 "This series cleans up the handling of DMA masks in a lot of drivers,
  fixing some bugs as we go.

  Some of the more serious errors include:
   - drivers which only set their coherent DMA mask if the attempt to
     set the streaming mask fails.
   - drivers which test for a NULL dma mask pointer, and then set the
     dma mask pointer to a location in their module .data section -
     which will cause problems if the module is reloaded.

  To counter these, I have introduced two helper functions:
   - dma_set_mask_and_coherent() takes care of setting both the
     streaming and coherent masks at the same time, with the correct
     error handling as specified by the API.
   - dma_coerce_mask_and_coherent() which resolves the problem of
     drivers forcefully setting DMA masks.  This is more a marker for
     future work to further clean these locations up - the code which
     creates the devices really should be initialising these, but to fix
     that in one go along with this change could potentially be very
     disruptive.

  The last thing this series does is prise away some of Linux's addition
  to "DMA addresses are physical addresses and RAM always starts at
  zero".  We have ARM LPAE systems where all system memory is above 4GB
  physical, hence having DMA masks interpreted by (eg) the block layers
  as describing physical addresses in the range 0..DMAMASK fails on
  these platforms.  Santosh Shilimkar addresses this in this series; the
  patches were copied to the appropriate people multiple times but were
  ignored.

  Fixing this also gets rid of some ARM weirdness in the setup of the
  max*pfn variables, and brings ARM into line with every other Linux
  architecture as far as those go"

John W. Linville says:

====================
Please accept this batch of updates intended for the 3.12 stream.

For the mac80211 bits, Johannes says this:

"This time I have various improvements all over the place: IBSS, mesh,
testmode, AP client powersave handling, one of the rare rfkill patches
and some code cleanup."

Also for mac80211:

"And I also have some more changes for -next, just a few small fixes and
improvements, nothing really stands out."

And for iwlwifi:

"This time I have some powersave work (notably uAPSD support), CQM
offloads, support for a new firmware API and various code cleanups."

Regarding the Bluetooth bits, Gustavo says:

"Patches to 3.12, here we have:

* implementation of a proper tty_port for RFCOMM devices, this fixes some
issues people were seeing lately in the kernel.
* Add voice_setting option for SCO, it is used for SCO Codec selection
* bugfixes, small improvements and clean ups"

For the NFC bits, Samuel says:

"With this one we have:

- A few pn533 improvements and minor fixes. Testing our pn533 driver
  against Google's NCI stack triggered a few issues that we fixed now.
  We also added Tx fragmentation support to this driver.

- More NFC secure element handling. We added a GET_SE netlink command
  for getting all the discovered secure elements, and we defined 2
  additional secure element netlink event (transaction and connectivity).
  We also fixed a couple of typos and copy-paste bugs from the secure
  element handling code.

- Firmware download support for the pn544 driver. This chipset can enter a
  special mode where it's waiting for firmware blobs to replace the
  already flashed one. We now support that mode."

With repect to the ath tree, Kalle says:

"New features in ath10k are rx/tx checsumming in hw and survey scan
implemented by Michal. Also he made fixes to different areas of the
driver, most notable being fixing the case when using two streams and
reducing the number of interface combinations to avoid firmware crashes.
Bartosz did a clean related to how we handle SoC power save in PCI
layer.

For ath6kl Mohammed and Vasanth sent each a patch to fix two infrequent
crashes."

I also pulled the wireless tree into wireless-next to support a
request from Johannes.  On top of all that, there are the usual
sort of driver updates.  The mwifiex, brcmfmac, brcmsmac, ath9k,
and rt2x00 drivers all get some attention, as does the bcma bus and
a few other random bits here and there.
