9731f82d60 ASoC: hdmi-codec: enable multi probe for same device
hdmi-codec driver is common HDMI sound driver,
but it doesn't care about multi sound ports.
For example, hdmi-codec driver is supporting 1 I2S and 1 SPDIF ports,
so, we can't use this driver if HDMI has 2 or more I2S ports.

And we would like to use multi detection.
For example, DesignWare HDMI driver is providing dw_hdmi_bind() to
DRM/KMS driver, and it will setups HDMI video/sound.
Note is that it will be called under for_each loop of ports.

int dw_hdmi_bind(xxx)
{
        /* register hdmi-codec driver here */
}

static int xxx_probe(struct platform_device *pdev)
{
        for_each_xxx(xx) {
                ...
                dw_hdmi_bind(xxx);
                ...
        }
}

This case, dw_hdmi_bind() would like to use hdmi-codec,
and it will be called multiple times for each ports.

Here, ASoC's CPU/Codec/Card bind will checks each "of_node" on DT,
and hdmi-codec driver is assuming its parent device for it.
But it doesn't care about case.
Thus, ASoC never detect correct sound card in this case.

To solve this issue, this patch checks each parent device,
and names "hdmi-hifi.x" in order to each ports.
And uses struct snd_soc_component_driver :: of_xlate_dai_name
for snd_soc_get_dai_name().

1eff9d322a block: rename bio bi_rw to bi_opf
Since commit 63a4cc2486, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.

No intended functional changes in this commit.

c11f0c0b5b block/mm: make bdev_ops->rw_page() take a bool for read/write
Commit abf545484d changed it from an 'rw' flags type to the
newer ops based interface, but now we're effectively leaking
some bdev internals to the rest of the kernel. Since we only
care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.

Then we can also move op_is_write() and friends back under
CONFIG_BLOCK protection.

e9d488c311 binfmt_misc for-linus on 20160727
First off, the intention of this pull is to declare that I'll be the
 binfmt_misc maintainer (mainly on the grounds of you touched it last,
 it's yours).  There's no MAINTAINERS entry, but get_maintainers.pl
 will now finger me.
 
 The update itself is to allow architecture emulation containers to
 function such that the emulation binary can be housed outside the
 container itself.  The container and fs parts both have acks from
 relevant experts.
 
 The change is user visible. To use the new feature you have to add an
 F option to your binfmt_misc configuration.  However, the existing
 tools, like systemd-binfmt work with this without modification.

From the docs:
 "The usual behaviour of binfmt_misc is to spawn the binary lazily when
  the misc format file is invoked.  However, this doesn't work very well
  in the face of mount namespaces and changeroots, so the F mode opens
  the binary as soon as the emulation is installed and uses the opened
  image to spawn the emulator, meaning it is always available once
  installed, regardless of how the environment changes"

337684a174 fs: return EPERM on immutable inode
In most cases, EPERM is returned on immutable inode, and there're only a
few places returning EACCES. I noticed this when running LTP on
overlayfs, setxattr03 failed due to unexpected EACCES on immutable
inode.

So converting all EACCES to EPERM on immutable inode.

Merge tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs

Pull more xfs updates from Dave Chinner:
 "This is the second part of the XFS updates for this merge cycle, and
  contains the new reverse block mapping feature for XFS.

  Reverse mapping allows us to track the owner of a specific block on
  disk precisely.  It is implemented as a set of btrees (one per
  allocation group) that track the owners of allocated extents.
  Effectively it is a "used space tree" that is updated when we allocate
  or free extents.  i.e. it is coherent with the free space btrees we
  already maintain and never overlaps with them.

  This reverse mapping infrastructure is the building block of several
  upcoming features - reflink, copy-on-write data, dedupe, online
  metadata and data scrubbing, highly accurate bad sector/data loss
  reporting to users, and significantly improved reconstruction of
  damaged and corrupted filesystems.  There's a lot of new stuff coming
  along in the next couple of cycles,a nd it all builds in the rmap
  infrastructure.

  As such, it's a huge chunk of new code with new on-disk format
  features and internal infrastructure.  It warns at mount time as an
  experimental feature and that it may eat data (as we do with all new
  on-disk features until they stabilise).  We have not released
  userspace suport for it yet - userspace support currently requires
  download from Darrick's xfsprogs repo and build from source, so the
  access to this feature is really developer/tester only at this point.
  Initial userspace support will be released at the same time kernel
  with this code in it is released.

  The new rmap enabled code regresses 3 xfstests - all are ENOSPC
  related corner cases, one of which Darrick posted a fix for a few
  hours ago.  The other two are fixed by infrastructure that is part of
  the upcoming reflink patchset.  This new ENOSPC infrastructure
  requires a on-disk format tweak required to keep mount times in
  check - we need to keep an on-disk count of allocated rmapbt blocks so
  we don't have to scan the entire btrees at mount time to count them.

  This is currently being tested and will be part of the fixes sent in
  the next week or two so users will not be exposed to this change"
