This reverts commit 69f0554ec261fd686ac7fa1c598cc9eb27b83a80.
This patch breaks randconfig on at least the x86-64 architecture, and
most likely on others. There is work underway to support uncompressed
kernels in a generic way, but it looks like it will amount to
rewriting the support from scratch; see the LKML thread in the Link:
for info.
Therefore, revert this change and wait for the fix.

Pull CIFS fixes from Steve French:
"A set of cifs fixes most important of which is Pavel's fix for some
problems with handling Windows reparse points and also the security
fix for setfacl over a cifs mount to Samba removing part of the ACL.
Both of these fixes are for stable as well.
Also added most of copychunk (copy offload) support to cifs although I
expect a final patch in that series (to fix handling of larger files)
in a few days (had to hold off on that in order to incorporate some
additional code review feedback).
Also added support for O_DIRECT on forcedirectio mounts (needed in
order to run some of the server benchmarks over cifs and smb2/smb3
mounts)"
* 'for-linus' of git://git.samba.org/sfrench/cifs-2.6:
[CIFS] Warn if SMB3 encryption required by server
setfacl removes part of ACL when setting POSIX ACLs to Samba
[CIFS] Set copychunk defaults

setfacl over cifs mounts can remove the default ACL when setting the

rather than setting to -1 the count field for the unaffected
half of the ACL. For example notice the setfacl removed
the default ACL in this sequence:

This first patch adds the ability for us to do a server side copy
(ie fast copy offloaded to the server to perform, aka refcopy)
"cp --reflink"
of one file to another located on the same server. This
is much faster than traditional copy (which requires
reading and writing over the network and extra
memcpys).
This first version is not going to be copy
files larger than about 1MB (to Samba) until I add
support for multiple chunks and for autoconfiguring
the chunksize.
It includes:
1) processing of the ioctl
2) marshalling and sending the SMB2/SMB3 fsctl over the network
3) simple parsing of the response
It does not include yet (these will be in followon patches to come soon):
1) support for multiple chunks
2) support for autoconfiguring and remembering the chunksize
3) Support for the older style copychunk which Samba 4.1 server supports
(because this requires write permission on the target file, which
cp does not give you, apparently per-posix). This may require
a distinct tool (other than cp) and other ioctl to implement.

A bit of cleanup plus some gratuitous variable renaming. I think using
structures instead of numeric offsets makes this code much more
understandable.
Also added a comment about current time range expected by
the server.

Opens on current cifs/smb2/smb3 mounts with O_DIRECT flag fail
even when caching is disabled on the mount. This was
reported by those running SMB2 benchmarks who need to
be able to pass O_DIRECT on many of their open calls to
reduce caching effects, but would also be needed by other
applications.
When mounting with forcedirectio ("cache=none") cifs and smb2/smb3
do not go through the page cache and thus opens with O_DIRECT flag
should work (when posix extensions are negotiated we even are
able to send the flag to the server). This patch fixes that
in a simple way.
The 9P client has a similar situation (caching is often disabled)
and takes the same approach to O_DIRECT support ie works if caching
disabled, but if client caching enabled it fails with EINVAL.
A followon idea for a future patch as Pavel noted, could
be that files opened with O_DIRECT could cause us to change
inode->i_fop on the fly from
cifs_file_strict_ops
to
cifs_file_direct_ops
which would allow us to support this on non-forcedirectio mounts
(cache=strict and cache=loose) as well.

Andrey reported that he was seeing cifs.ko spam the logs with messages
like this:
CIFS VFS: Unexpected lookup error -26
He was listing the root directory of a server and hitting an error when
trying to QUERY_PATH_INFO against hiberfil.sys and pagefile.sys. The
right fix would be to switch the lookup code over to using FIND_FIRST,
but until then we really don't need to report this at a level of
KERN_ERR. Convert this message over to FYI level.

Sometimes, the server will report an error that basically indicates
that it's running out of resources. These include these under SMB1:
NT_STATUS_NO_MEMORY
NT_STATUS_SECTION_TOO_BIG
NT_STATUS_TOO_MANY_PAGING_FILES
...and this one under SMB2:
STATUS_NO_MEMORY
Currently, this gets mapped to ENOMEM by the client, but that's
confusing as an ENOMEM error is typically an indicator that the
client is out of memory.
Change these errors to instead map to EREMOTEIO to indicate that
the problem is actually server-side and not on the client.

Now we treat any reparse point as a symbolic link and map it to a Unix
one that is not true in a common case due to many reparse point types
supported by SMB servers.
Distinguish reparse point types into two groups:
1) that can be accessed directly through a reparse point
(junctions, deduplicated files, NFS symlinks);
2) that need to be processed manually (Windows symbolic links, DFS);
and map only Windows symbolic links to Unix ones.

The current test on valid use of the "migration" mount option can never
report an error as it will only do so if
mnt->version !=4 && mnt->minor_version != 0
(and some other condition), but if that test would succeed, then the previous
test has already gone-to out_minorversion_mismatch.
So change the && to an || to get correct semantics.

Currently, when we try to mount and get back NFS4ERR_CLID_IN_USE or
NFS4ERR_WRONGSEC, we create a new rpc_clnt and then try the call again.
There is no guarantee that doing so will work however, so we can end up
retrying the call in an infinite loop.
Worse yet, we create the new client using rpc_clone_client_set_auth,
which creates the new client as a child of the old one. Thus, we can end
up with a *very* long lineage of rpc_clnts. When we go to put all of the
references to them, we can end up with a long call chain that can smash
the stack as each rpc_free_client() call can recurse back into itself.
This patch fixes this by simply ensuring that the SETCLIENTID call will
only be retried in this situation if the last attempt did not use
RPC_AUTH_UNIX.
Note too that with this change, we don't need the (i > 2) check in the
-EACCES case since we now have a more reliable test as to whether we
should reattempt.

In cases where an rpc client has a parent hierarchy, then
rpc_free_client may end up calling rpc_release_client() on the
parent, thus recursing back into rpc_free_client. If the hierarchy
is deep enough, then we can get into situations where the stack
simply overflows.
The fix is to have rpc_release_client() loop so that it can take
care of the parent rpc client hierarchy without needing to
recurse.

The following scenario can cause silent data corruption when doing
NFS writes. It has mainly been observed when doing database writes
using O_DIRECT.
1) The RPC client uses sendpage() to do zero-copy of the page data.
2) Due to networking issues, the reply from the server is delayed,
and so the RPC client times out.
3) The client issues a second sendpage of the page data as part of
an RPC call retransmission.
4) The reply to the first transmission arrives from the server
_before_ the client hardware has emptied the TCP socket send
buffer.
5) After processing the reply, the RPC state machine rules that
the call to be done, and triggers the completion callbacks.
6) The application notices the RPC call is done, and reuses the
pages to store something else (e.g. a new write).
7) The client NIC drains the TCP socket send buffer. Since the
page data has now changed, it reads a corrupted version of the
initial RPC call, and puts it on the wire.
This patch fixes the problem in the following manner:
The ordering guarantees of TCP ensure that when the server sends a
reply, then we know that the _first_ transmission has completed. Using
zero-copy in that situation is therefore safe.
If a time out occurs, we then send the retransmission using sendmsg()
(i.e. no zero-copy), We then know that the socket contains a full copy of
the data, and so it will retransmit a faithful reproduction even if the
RPC call completes, and the application reuses the O_DIRECT buffer in
the meantime.

It's safer to turn on regcache_cache_only before disabling regulator since
the driver will turn off the regcache_cache_only after enabling regulator.
If we remain cache_only false, some command like 'amixer cset' would get
failure if being run before wm8962_resume().

Unbalanced calls to snd_imx_pcm_trigger() may result in endless
FIQ activity and thus provoke eternal sound. While on the first glance,
the switch statement looks pretty symmetric, the SUSPEND/RESUME
pair is not: the suspend case comes along snd_pcm_suspend_all(),
which for fsl/imx-pcm-fiq is called only at snd_soc_suspend(),
but the resume case originates straight from the SNDRV_PCM_IOCTL_RESUME.
This way userland may provoke an unbalanced resume, which might cause
the fiq_enable counter to increase and never return to zero again,
so eventually imx_pcm_fiq is never disabled.
Simply removing the fiq_enable will solve the problem, as long as
one never goes play and capture game simultaneously, but beware
trying both at once, the early TRIGGER_STOP will cut off the other
activity prematurely. So now playing and capturing is scrutinized
separately, instead of by counting.

The recent change in sysfs triggered a kernel WARNING at unloading a
sound driver like
WARNING: CPU: 3 PID: 2247 at fs/sysfs/group.c:214 sysfs_remove_group+0xe8/0xf0()
sysfs group ffffffff81ab7b20 not found for kobject 'event14'
for each jack instance. It's because the unregistration of jack input
device is done in dev_free callback, which is called after
snd_card_disconnect(). Since device_unregister(card->card_dev) is
called in snd_card_disconnect(), the whole sysfs entries belonging to
card->card_dev have been already removed recursively. Thus this
results in a warning as input_unregister_device() yet tries to
unregister the already removed sysfs entry.
For fixing this mess, we need to unregister the jack input device at
dev_disconnect callback so that it's called before unregistering the
card->card_dev.

The current code may access to the already freed object. The input
device must be accessed and unregistered before freeing the top level
sound object.

snd_hda_codec_reset() is called either in resetting the whole setup at
error paths or hwdep clear/reconfig sysfs triggers. But all of these
don't assume that the power has to be off, rather they want to keep
the power state unchanged (e.g. reconfig_codec() calls the power
up/down by itself). Thus, unconditionally clearing the power state in
snd_hda_codec_reset() leads to the inconsistency, confuses the further
operation. This patch gets rid of the lines doing that bad thing.

Similarly as other laptops with AD1981 & co codecs, we can control
EAPD on AD1986A more safely depending on the Master switch, in order
to save some power.

The only EAPD on AD1986A is on NID 0x1b where usually the speaker.
But this doesn't control only the speaker amp but may influence on all
outputs, e.g. Lenovo N100 laptop seems to have this issue.

We don't change the EAPD bit in set_pin_eapd() if keep_eapd_on flag is
set by the codec driver and enable is false. But, we also apply the
flipping of enable value according to inv_eapd flag in the same
function, and this confused the former check, handled as if it's
turned ON. The inverted EAPD check must be applied after keep_eapd_on
check, instead.

Pausing audio playback is not an illegal state so it doesn't
seem sensible for poll() to return -EBADFD on a paused stream.
There's also no reason to assume that we can't write more data
to the DSP while playback is paused. Remove the -EBADFD so that
a stream in paused state will still report the buffer
availability from poll(). It is up to the user process to
manage its state so that it knows whether it is paused or not.

According to the HDA specification the baseline ELD length is counted in
DW of 4 bytes instead of in bytes.
Fix the code accordingly.
Baseline length is not used by the kernel so only the ELD exported to
userspace was affected. No issues have been reported.
v2: Fixed so that eld_size is adjusted upwards accordingly as well.

The ATI/AMD video/audio latencies are specified in apparent HDMI VSDB
format. In this format values above 251 are not valid (or stream
component is not supported - 255), but no checking is performed since
this was not mentioned in the AMD HDA verbs specification.

describing the formats.

Add error checks to HBR status reads (both generic and ATI/AMD) and
ATI/AMD codec reads for ELD generation.
Unchecked errors in these just caused more errors later on (invalid
codec writes for the HBR ones and ELD parsing errors for the ATI/AMD ELD
ones), but it is better to catch them earlier.

According to USB Audio spec v2 bits 25 and 26 of bmChannelConfig are
"Back Left of Center - BLC" and "Back Right of Center - BRC",
respectively.
They are currently assigned to ALSA channels BLC/BRC. However, the ALSA
BLC/BRC are actually the rather nonsensical "bottom left center" and
"bottom right center", so the channels will be assigned wrongly. The
comments in the USB code are also similarly wrong, so this is not
readily apparent without looking at the actual specification.
Fix the channel mapping by mapping bits 25 and 26 to RLC (Rear Left
Center) and RRC (Rear Right Center), respectively, instead.

Channel map positions FLH, FCH, FRH duplicate positions TFL, TFC, TFR.
Both are the speakers above the front speakers (CEA uses "high" and USB
audio uses "top" nomenclature).
Since the USB audio code has used the TFx positions since v3.8
(04324ccc75f96, "ALSA: usb-audio: add channel map support") but the HDMI
code only just started using FxH in a5b7d510b2220cccb ("ALSA: hda -
hdmi: Fix channel maps with less common speakers") which is not yet in
any released kernel, standardize on TFx instead.
