Helge Deller 54e181e073 parisc: Do not crash 64bit SMP kernels on machines with >= 4GB RAM
Since the beginning of the parisc-linux port, sometimes 64bit SMP kernels were
not able to bring up other CPUs than the monarch CPU and instead crashed the
kernel.  The reason was unclear, esp. since it involved various machines (e.g.
J5600, J6750 and SuperDome). Testing showed, that those crashes didn't happened
when less than 4GB were installed, or if a 32bit Linux kernel was booted.

In the end, the fix for those SMP problems is trivial:
During the early phase of the initialization of the CPUs, including the monarch
CPU, the PDC_PSW firmware function to enable WIDE (=64bit) mode is called.
It's documented that this firmware function may clobber various registers, and
one one of those possibly clobbered registers is %cr30 which holds the task
thread info pointer.

Now, if %cr30 would always have been clobbered, then this bug would have been
detected much earlier. But lots of testing finally showed, that - at least for
%cr30 - on some machines only the upper 32bits of the 64bit register suddenly
turned zero after the firmware call.

So, after finding the root cause, the explanation for the various crashes
became clear:
- On 32bit SMP Linux kernels all upper 32bit were zero, so we didn't faced this
  problem.
- Monarch CPUs in 64bit mode always booted sucessfully, because the inital task
  thread info pointer was below 4GB.
- Secondary CPUs booted sucessfully on machines with less than 4GB RAM because
  the upper 32bit were zero anyay.
- Secondary CPus failed to boot if we had more than 4GB RAM and the task thread
  info pointer was located above the 4GB boundary.

Finally, the patch to fix this problem is trivial by saving the %cr30 register
before the firmware call and restoring it afterwards.

Takashi Iwai 1ac3293095 ALSA: hda - Fix silent headphone on Thinkpads with AD1984A codec
AD1984A codec has a couple of pins with EAPD controls, and the generic
codec driver tries to turn each of them on/off depending on the pin
active state.  However, Thinkpads seem to use EAPD of the speaker pin
as a master EAPD for controlling the mute of all outputs, including
the headphone.  This results in the dead headphone output via the
headphone plugging because it mutes the speaker and turns off EAPD.

The fix is to simply add spec->gen.keep_on_eapd flag.

[This is a regression fix on 3.12 where we moved the AD codec parser
 to the generic parser.  3.11 and earlier didn't show this problem
 because still static quirks have been used.]

Takashi Iwai b63eae0a6c ALSA: hda - Add missing initial vmaster hook at build_controls callback
The generic parser has a support of vmaster hook, but this is
initialized only in the init callback with the check of the presence
of the corresponding kctl.  However, since kctl is NULL at the very
first init callback that is called before build_controls callback, the
vmaster hook sync is skipped there.  Eventually this leads to the
uninitialized state depending on the hook implementation.

This patch adds a simple workaround, just calling the sync function
explicitly at build_controls callback.

Nicholas Bellinger 60a01f558a vhost/scsi: Fix incorrect usage of get_user_pages_fast write parameter
This patch addresses a long-standing bug where the get_user_pages_fast()
write parameter used for setting the underlying page table entry permission
bits was incorrectly set to write=1 for data_direction=DMA_TO_DEVICE, and
passed into get_user_pages_fast() via vhost_scsi_map_iov_to_sgl().

However, this parameter is intended to signal WRITEs to pinned userspace
PTEs for the virtio-scsi DMA_FROM_DEVICE -> READ payload case, and *not*
for the virtio-scsi DMA_TO_DEVICE -> WRITE payload case.

This bug would manifest itself as random process segmentation faults on
KVM host after repeated vhost starts + stops and/or with lots of vhost
endpoints + LUNs.

David Woodhouse 031e2777e0 mtd: gpmi: fix ECC regression
The "legacy" ECC layout used until 3.12-rc1 uses all the OOB area by
computing the ECC strength and ECC step size ourselves.

Commit 2febcdf84b ("mtd: gpmi: set the BCHs geometry with the ecc info")
makes the driver use the ECC info (ECC strength and ECC step size)
provided by the MTD code, and creates a different NAND ECC layout
for the BCH, and use the new ECC layout. This causes a regression:

   We can not mount the ubifs which was created by the old NAND ECC layout.

This patch fixes this issue by reverting to the legacy ECC layout.

We will probably introduce a new device-tree property to indicate that
the new ECC layout can be used. For now though, for the imminent 3.12
release, we just unconditionally revert to the 3.11 behaviour.

This leaves a harmless cosmetic warning about an unused function. At
this point in the cycle I really don't care.

Gu Zheng 05e16745c0 seq_file: always update file->f_pos in seq_lseek()
This issue was first pointed out by Jiaxing Wang several months ago, but no
further comments:
https://lkml.org/lkml/2013/6/29/41

As we know pread() does not change f_pos, so after pread(), file->f_pos
and m->read_pos become different. And seq_lseek() does not update file->f_pos
if offset equals to m->read_pos, so after pread() and seq_lseek()(lseek to
m->read_pos), then a subsequent read may read from a wrong position, the
following program produces the problem:

    char str1[32] = { 0 };
    char str2[32] = { 0 };
    int poffset = 10;
    int count = 20;

    /*open any seq file*/
    int fd = open("/proc/modules", O_RDONLY);

    pread(fd, str1, count, poffset);
    printf("pread:%s\n", str1);

    /*seek to where m->read_pos is*/
    lseek(fd, poffset+count, SEEK_SET);

    /*supposed to read from poffset+count, but this read from position 0*/
    read(fd, str2, count);
    printf("read:%s\n", str2);

out put:
pread:
 ck_netbios_ns 12665
read:
 nf_conntrack_netbios

/proc/modules:
nf_conntrack_netbios_ns 12665 0 - Live 0xffffffffa038b000
nf_conntrack_broadcast 12589 1 nf_conntrack_netbios_ns, Live 0xffffffffa0386000

So we always update file->f_pos to offset in seq_lseek() to fix this issue.

Linus Torvalds 4208c47199 ARM: SoC fixes for 3.12-rc
There's really only one bugfix in this branch, which is a fix for timers on
 the integrator platform. Since Linus Walleij is resurrecting support for
 the platform it seems valuable to get the fix into 3.12 even though the
 regression has been around a while.
 
 The rest are a handful of maintainers updates. If you prefer to hold those
 until 3.13 then just merge the first patch on the branch which is the fix.

software_resume is being called after deferred_probe_initcall in
drivers base. If the probing of the device that contains the resume
image is deferred, and the system has been instructed to wait for
it to show up, this wait will occur in software_resume. This causes
a deadlock.

Move software_resume into late_initcall_sync so that it happens
after all the other late_initcalls.

Anssi Hannula 7342017f4a ALSA: hda - hdmi: Re-setup pin and infoframe on plug-in on all codecs
hdmi_setup_audio_infoframe() does not set up pin and infoframe if there
is no connected sink. If a sink is connected while audio playback is
already in progress, the pin and infoframe will not be properly set up,
causing no audio or wrongly mapped audio.

On Intel Haswell codecs the hdmi_setup_audio_infoframe() is already
called again from hdmi_present_sense() when an ELD appears because
transcoder:port mapping may have changed.

Make the call non-Haswell-specific so that audio will be properly set up
if the playback was started before a sink was connected.

Tested on non-Haswell Intel HDMI codec by plugging sink in during
playback.

In a recent commit:

  commit f455578dd9
  Author: Ezequiel Garcia <ezequiel.garcia@free-electrons.com>
  Date:   Mon Aug 12 14:14:53 2013 -0300

  mtd: nand: pxa3xx: Remove hardcoded mtd name

  There's no advantage in using a hardcoded name for the mtd device.
  Instead use the provided by the platform_device.

The MTD name was changed to use the one provided by the platform_device.
However, this can be problematic as some users want to set partitions
using the kernel parameter 'mtdparts', where the name is needed.

Therefore, to avoid regressions in users relying in 'mtdparts' we revert
the change and use the previous one 'pxa3xx_nand-0'.

While at it, let's put a big comment and prevent this change from happening
ever again.

Anssi Hannula 84d69e790f ALSA: hda - hdmi: Disable ramp-up/down for non-PCM on AMD codecs
Recent AMD HDMI codecs (revision ID 3 and later, 0x100300 as reported by
procfs codec#0) have a configurable ramp-up/down functionality.

The documentation ( http://www.x.org/docs/AMD/AMD_HDA_verbs_v2.pdf )
specifies that 180 ("180/256 =~ 0.7") is recommended for PCM and 0 for
non-PCM.

Apply the recommended values according to provided S/PDIF AES0 settings
since ramp-up/down does not make sense for non-PCM.

v2: adapted to hdmi_ops infrastructure

* More note from Anssi:
actually, re-reading mails reveals that Olivier didn't find the
expected difference with this setting, except for "maybe slightly
slower startup with AES0=6" (i.e. value 0, which is unexpected).

So maybe
a) it makes too unnoticiable a difference, or
b) only affects certain hardware (card and/or sink), or
c) ramp-up/down is only triggered with the MUTE bit of
   ATI_VERB_SET_MULTICHANNEL_xx which is also rev3+ specific,
   but is not presently used by the driver,
or something else.

So there's a significant chance setting ramp rate is useless for us ATM,
but probably does not do actual harm either.

Anssi Hannula 5a61358433 ALSA: hda - hdmi: Add ATI/AMD multi-channel audio support
ATI/AMD codecs do not support all the standard HDA HDMI/DP functions,
instead various vendor-specific verbs are provided.

This commit addresses these missing functions:
- standard channel mapping support
- standard infoframe configuration support

ATI/AMD provides their own verbs that allow the following:
- setting CA for infoframe
- setting down-mix information for infoframe
- channel pair remapping
- individual channel remapping (revision ID 3+, 0x100300+)

The documentation for the verbs has now been released by AMD:
http://www.x.org/docs/AMD/AMD_HDA_verbs_v2.pdf

Add support for the ATI/AMD specific verbs and use them instead of the
generic methods on ATI/AMD codecs. This allows multi-channel PCM audio
to work.

Channel remapping is restricted to pairwise mapping on codecs with
revision ID 2 (0x100200 as reported by procfs codec#X) or lower. This
means cards up to Radeon HD7670 as far as I know. This will not affect
standard multi-channel modes since these codecs support automatic
FC-LFE swapping for HDMI.

ATI/AMD codecs do not advertise all of their supported rates, formats
and channel counts, therefore that information is forced accordingly so
that all HDMI 1.x PCM parameters are marked as supported.

Support for multiple ports is also added to patch_atihdmi so that
0x1002aa01 codecs with multiple ports will work properly when switched
back to that patch.

v2: splitted ELD emulation to a separate patch, tlv fixes
v3: adapted to the new hdmi_ops infrastructure, fixed rev3+ vendor id
