Linus Torvalds a54769c505 sound fixes for 3.4-rc4
Fixes for a few regressions of HD-audio, originated partly from 3.4
 and partly 3.3.
 The fixes for ThinkPad docking-station are for 3.3 kernels, thus they
 are based on 3.3 then merged back to 3.4, so that they can be merged
 to stable tree cleanly.  The non-trivial merge conflicts are because
 of this action.
 
 In addition, a copule of trivial fixes for documentation and a long-
 statnding issue in the listing of built-in sound driver at boot time.

Timur Tabi 8a95bc8dfe powerpc/85xx: don't call of_platform_bus_probe() twice
Commit 46d026ac ("powerpc/85xx: consolidate of_platform_bus_probe calls")
replaced platform-specific of_device_id tables with a single function
that probes the most of the busses in 85xx device trees.  If a specific
platform needed additional busses probed, then it could call
of_platform_bus_probe() again.  Typically, the additional platform-specific
busses are children of existing busses that have already been probed.
of_platform_bus_probe() does not handle those child busses automatically.

Unfortunately, this doesn't actually work.  The second (platform-specific)
call to of_platform_bus_probe() never finds any of the busses it's asked
to find.

To remedy this, the platform-specific of_device_id tables are eliminated,
and their entries are merged into mpc85xx_common_ids[], so that all busses
are probed at once.

Eric W. Biederman 3adadc08cc net ax25: Reorder ax25_exit to remove races.
While reviewing the sysctl code in ax25 I spotted races in ax25_exit
where it is possible to receive notifications and packets after already
freeing up some of the data structures needed to process those
notifications and updates.

Call unregister_netdevice_notifier early so that the rest of the cleanup
code does not need to deal with network devices.  This takes advantage
of my recent enhancement to unregister_netdevice_notifier to send
unregister notifications of all network devices that are current
registered.

Move the unregistration for packet types, socket types and protocol
types before we cleanup any of the ax25 data structures to remove the
possibilities of other races.

The MC77xx devices can operate in two modes: "Direct IP" or "QMI",
switchable using a password protected AT command.  Both product ID
and USB interface configuration will change when switched.

The "sierra_net" driver supports the "Direct IP" mode.  This driver
supports the "QMI" mode.

There are also multiple possible USB interface configurations in each
mode, some providing more than one wwan interface.  Like many other
devices made for Windows, different interface types are identified
using a static interface number.  We define a Sierra specific
interface whitelist to support this.

The sp_pri_to_cos[] array size depends on the config but lets say it is
BX_E3B0_MAX_NUM_COS_PORT0 and max_num_of_cos is also
DCBX_E3B0_MAX_NUM_COS_PORT0.  In the original code
"pri == max_num_of_cos" was accepted but it is one past the end of the
array.

Also we used "pri" before capping it.  It's a harmless read past the end
of the array, but it would affect which error message gets printed.

Konrad Rzeszutek Wilk 3066616ce2 xen/xenbus: Add quirk to deal with misconfigured backends.
A rather annoying and common case is when booting a PVonHVM guest
and exposing the PV KBD and PV VFB - as broken toolstacks don't
always initialize the backends correctly.

Normally The HVM guest is using the VGA driver and the emulated
keyboard for this (though upstream version of QEMU implements
PV KBD, but still uses a VGA driver). We provide a very basic
two-stage wait mechanism - where we wait for 30 seconds for all
devices, and then for 270 for all them except the two mentioned.

That allows us to wait for the essential devices, like network
or disk for the full 6 minutes.

To trigger this, put this in your guest config:

vfb = [ 'vnc=1, vnclisten=0.0.0.0 ,vncunused=1']

instead of this:
vnc=1
vnclisten="0.0.0.0"

Takashi Iwai d70f363222 ALSA: hda/conexant - Set up the missing docking-station pins
ThinkPad 410,420,510,520 and X201 with cx50585 & co chips have the
docking-station ports, but BIOS doesn't initialize for these pins.
Thus, like the former X200, we need to set up the pins manually in the
driver.

The odd part is that the same PCI SSID is used for X200 and T400, thus
we need to prepare individual fixup tables for cx5051 and others.

Dave Airlie a09d431f34 drm/radeon: fix load detect on rn50 with hardcoded EDIDs.
When the force changes went in back in 3.3.0, we ended up returning
disconnected in the !force case, and the connected in when forced,
as it hit the hardcoded check.

Fix it so all exits go via the hardcoded check and stop spurious
modesets on platforms with hardcoded EDIDs.

Prathyush 4e47e02d1a drm: Releasing FBs before releasing GEM objects during drm_release
During DRM release, all the FBs and gem objects are released. If
a gem object is being used as a FB and set to a crtc, it must not
be freed before releasing the framebuffer first.

If FBs are released first, the crtc using the FB is disabled first
so now the GEM object can be freed safely. The CRTC will be enabled
again when the driver restores fbdev mode.

NUL-terminate after strncpy.

If the parameter "profile" has length 16 or more, then strncpy
leaves "string" with no NUL terminator, so the following search
for '\n' may read beyond the end of that 16-byte buffer.
If it finds a newline there, then it will also write beyond the
end of that stack buffer.

it not working properly with recent userspace, but it is default y

systems.

Kuninori Morimoto 590b4775d6 ALSA: workaround: change the timing of alsa_sound_last_init()
Current alsa_sound_last_init() was called as __initcall().
So, on current ALSA, only devices that had been properly
registered at this point were shown.
So, it will show "No soundcards found" if driver requests
probe deferment. it's often misleading.
This patch delays the timing of alsa_sound_last_init()
as workaround.

Hugh Dickins 9b7f43afd4 memcg: fix Bad page state after replace_page_cache
My 9ce70c0240 "memcg: fix deadlock by inverting lrucare nesting" put a
nasty little bug into v3.3's version of mem_cgroup_replace_page_cache(),
sometimes used for FUSE.  Replacing __mem_cgroup_commit_charge_lrucare()
by __mem_cgroup_commit_charge(), I used the "pc" pointer set up earlier:
but it's for oldpage, and needs now to be for newpage.  Once oldpage was
freed, its PageCgroupUsed bit (cleared above but set again here) caused
"Bad page state" messages - and perhaps worse, being missed from newpage.
(I didn't find this by using FUSE, but in reusing the function for tmpfs.)

Through the transition to the auto-parser, the support for

- This machine doesn't like the default COEF setup for ALC260 we take

- BIOS doesn't set the pins correctly at all; especially the machine
  uses only the pin 0x0f for both headphone and speaker

This patch adds the fixup as a workaround for these issues.

We experienced some issues while compiling some drivers as modules: Joachim has
 corrected several of them. We may reduce this number of exported values by
 reworking some drivers, in the future.
 Some drivers are also modified here, I would like to keep them in the series
 as the modifications are really related with our recent move to irqdomains or
 simply related with compiler annotations.
 I keep dmaengine Kconfig modification in this "fixes" series. The DMA
 driver will not be available for 9x5 SoC family otherwise.
