Pull powerpc fixes from Ben Herrenschmidt:
"The main thing that caused problem was that CONFIG_CPU_LITTLE_ENDIAN
got turned on with allyesconfig and such, which is not a very good
idea especially since it requires a newer toolchain than what most
people have.
So we turned it into a choice instead that defaults to big endian"

commit 566c09c53455d7c4f1 raid5: relieve lock contention in get_active_stripe()
modified the locking in get_active_stripe() reducing the range
protected by the (highly contended) device_lock.
Unfortunately it reduced the range too much opening up some races.
One race can occur if get_priority_stripe runs between the
test on sh->count and device_lock being taken.
This will mean that sh->lru is not empty while get_active_stripe
thinks ->count is zero resulting in a 'BUG' firing.
Another race happens if __release_stripe is called immediately
after sh->count is tested and found to be non-zero. If STRIPE_HANDLE
is not set, get_active_stripe should increment ->active_stripes
when it increments ->count from 0, but as it didn't think it was 0,
it doesn't.
Extending device_lock to cover the test on sh->count close these
races.
While we are here, fix the two BUG tests:
-If count is zero, then lru really must not be empty, or we've
lock the stripe_head somehow - no other tests are relevant.
-STRIPE_ON_RELEASE_LIST is completely independent of ->lru so
testing it is pointless.

commit 7a0a5355cbc71efa md: Don't test all of mddev->flags at once.
made most tests on mddev->flags safer, but missed one.
When
commit 260fa034ef7a4ff8b7306 md: avoid deadlock when dirty buffers during md_stop.
added MD_STILL_CLOSED, this caused md_check_recovery to misbehave.
It can think there is something to do but find nothing. This can
lead to the md thread spinning during array shutdown.

If a cgroup file implements either read_map() or read_seq_string(),
such file is served using seq_file by overriding file->f_op to
cgroup_seqfile_operations, which also overrides the release method to
single_release() from cgroup_file_release().
Because cgroup_file_open() didn't use to acquire any resources, this
used to be fine, but since f7d58818ba42 ("cgroup: pin
cgroup_subsys_state when opening a cgroupfs file"), cgroup_file_open()
pins the css (cgroup_subsys_state) which is put by
cgroup_file_release(). The patch forgot to update the release path
for seq_files and each open/release cycle leaks a css reference.
Fix it by updating cgroup_file_release() to also handle seq_files and
using it for seq_file release path too.

MIC card and host drivers are able to use virtio over the PCIe bus by
treating ioremap return values for the prefetchable BARs as pointers,
effectively treating I/O memory the same as system memory. However this
results in sparse warnings. Knowing that these warnings do not point to
a functional issue, this patch suppresses these warnings.

Endianness issues are now consistent as per the documentation in
host/mic_virtio.h. Sparse warnings related to endianness are also fixed.
Note that the MIC driver implementation assumes that the host can be

Avoid declaring ALIGN() and __aligned() in
include/uapi/linux/mic_common.h since they pollute user space
namespace. Also, mic_aligned_size() can be simply replaced simply by
sizeof() since all structures where mic_aligned_size() is used are
declared using __attribute__ ((aligned(8)));

Subject: Namespace pollution in mic_common.h
This puts two macros, ALIGN() and __aligned(), into arbitrary user space
namespace. This really isn't safe or acceptable, especially since those
symbols are highly generic.
...
When these structures are forced-aligned, they will in fact have padding
automatically added by the compiler to an 8-byte boundary anyway, so
mic_aligned_size() does nothing.

MIC user space daemon poll's on sysfs changes. The documentation for
sysfs_poll(...) in fs/sysfs/file.c states that "Once poll/select
indicates that the value has changed, you need to close and re-open the
file, or seek to 0 and read again". This step was missed out earlier and
resulted in the daemon spinning continuously rather than getting blocked
in 'poll'. This bug was exposed by commit aea585ef8fa65163 introduced as
part of sysfs changes in 3.13-rc1. A seek to 0 has been introduced to
fix it.

The source of this problem is that SCSI hosts are removed from
ATA ports after calling ata_tport_delete() which removes the
port's sysfs directory, among other things. Now, after commit
bcdde7e221a8, the sysfs directory is removed along with all of
its subdirectories that include the SCSI host's sysfs directory
and its subdirectories at this point. Consequently, when
device_del() is finally called for any child device of the SCSI
host and tries to remove its "power" group (which is already
gone then), it triggers the above warning.
To make the warnings go away, change the removal ordering in
ata_port_detach() so that the SCSI host is removed from the
port before ata_tport_delete() is called.

This is an actual deadlock because an interrupt doing an allocation will
hit get_mems_allowed()->...->__read_seqcount_begin(), which will spin
forever waiting for the write side to complete.

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.
Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

There seems to be no active maintainer for the driver, and there is an

Hopefully someone steps up to be the maintainer, and works to get this

This patch fixes the setting of the register KIRKWOOD_PLAYCTL which did
always streaming on both I2S and SPDIF, ignoring the DAI ID.
The bug was introduced by the commit 75b9b65ee5a

Eliminate the gap between DT becoming available and this being used to say
we have full constraints by checking directly for DT every time we check
for full constraints. This improves interoperaton with optional regulator
support.

snd_pcm_limit_hw_rates() will initialize the minimum and maximum sample rate for
the PCM stream based on the rates specified in the rates field. Since we call
snd_pcm_limit_hw_rates() after soc_pcm_init_runtime_hw() it will essentially
overwrite the min and max rate set in soc_pcm_init_runtime_hw(). This may cause
the minimum or maximum rate to be set to a value outside the range of one of the
components if one of the components sets either SNDRV_PCM_RATE_CONTINUOUS or
SNDRV_PCM_RATE_KNOT and the other component specified a discrete rate via
SNDRV_PCM_RATE_[0-9]* that is outside of the first component's rate range. To
fix this first calculate the minimum and maximum rates using
snd_pcm_limit_hw_rates() and then on top of that apply the contraints specified
in the snd_soc_pcm_stream structs.

In order to make sure that the sample rate is in the supported range of both
components the maximum rate of the card should be the minimum of the maximum
rate of each components. There is one special case to consider though, if
max_rate is set to 0 this means there is no maximum specified, so use
min_not_zero() macro which will give use the desired result.

Simple code reorganisation so we can change the logic for deciding what
full constraints are more easily.

As the priv is not assigned to card->drvdata, it is NULL, so when
unload module, it will cause NULL pointer oops.
Assign priv to card->drvdata to fix this issue.

When the hp mic pin has no VREF bits, the driver forgot to set PIN_IN
bit. Spotted during debugging old MacBook Airs.
