8c40041f75 perf kmem: Fix breakage introduced by 5a0e3ad slab.h script
Commit 5a0e3ad ("include cleanup: Update gfp.h and slab.h
includes to prepare for breaking implicit slab.h inclusion
from percpu.h") added a '#include <linux/slab.h>' to
tools/perf/builtin-kmem.h because: that tool has lines like
this:

        if (!strcmp(event->name, "kmalloc") ||
            !strcmp(event->name, "kmem_cache_alloc")) {
                process_alloc_event(data, event, cpu, timestamp, thread, 0);
                return;
        }

So, using the script regex:

>>> import re
>>> s = re.compile(r'^(|.*[^a-zA-Z0-9_])_*(slab_is_available|kmem_cache_|k[mzc]alloc|krealloc|kz?free|ksize|__getname|putname)')
>>> l = '   !strcmp(event->name, "kmem_cache_alloc")) {'
>>> s.search(l)
<_sre.SRE_Match object at 0xb77b1ad0>
>>>

Remove that file that is not available in the tools/perf include
path and thus builtin-kmem.c couldn't be compiled.

445d211b0d libata: unlock HPA if device shrunk
Some BIOSes don't configure HPA during boot but do so while resuming.
This causes harddrives to shrink during resume making libata detach
and reattach them.  This can be worked around by unlocking HPA if old
size equals native size.

Add ATA_DFLAG_UNLOCK_HPA so that HPA unlocking can be controlled
per-device and update ata_dev_revalidate() such that it sets
ATA_DFLAG_UNLOCK_HPA and fails with -EIO when the above condition is
detected.

This patch fixes the following bug.

68b0ddb289 libata: disable NCQ on Crucial C300 SSD
Crucial said,

  Thank you for contacting us. We know that with our M225 line of SSDs
  you sometimes need to disable NCQ (native command queuing) to avoid
  just the type of errors you're seeing. Our recommendation for the
  M225 is to add libata.force=noncq to your Linux kernel boot options,
  under the kernel ATA library option.

  I have sent your feedback to the engineers working on the C300, and
  asked them to please pass it on to the firmware team. I have been
  notified that they are in the process of testing and finalizing a
  new firmware version, that you can expect to see released around the
  end of April. We’ll keep you posted as to when it will be available
  for download.

So, turn off NCQ on the drive w/ the current firmware revision.

5fbfb18d7a Fix up possibly racy module refcounting
Module refcounting is implemented with a per-cpu counter for speed.
However there is a race when tallying the counter where a reference may
be taken by one CPU and released by another.  Reference count summation
may then see the decrement without having seen the previous increment,
leading to lower than expected count.  A module which never has its
actual reference drop below 1 may return a reference count of 0 due to
this race.

Module removal generally runs under stop_machine, which prevents this
race causing bugs due to removal of in-use modules.  However there are
other real bugs in module.c code and driver code (module_refcount is
exported) where the callers do not run under stop_machine.

Fix this by maintaining running per-cpu counters for the number of
module refcount increments and the number of refcount decrements.  The
increments are tallied after the decrements, so any decrement seen will
always have its corresponding increment counted.  The final refcount is
the difference of the total increments and decrements, preventing a
low-refcount from being returned.

bb17ef102b davinci: edma: clear events in edma_start()
This patch fixes an issue where a DMA channel can erroneously process an
event generated by a previous transfer.  A failure case is where DMA is
being used for SPI transmit and receive channels on OMAP L138.  In this
case there is a single bit that controls all event generation from the
SPI peripheral.  Therefore it is possible that between when edma_stop()
has been called for the transmit channel on a previous transfer and
edma_start() is called for the transmit channel on a subsequent transfer,
that a transmit event has been generated.

The fix is to clear events in edma_start().  This prevents false events
from being processed when events are enabled for that channel.

449cedf099 audit: preface audit printk with audit
There have been a number of reports of people seeing the message:
"name_count maxed, losing inode data: dev=00:05, inode=3185"
in dmesg.  These usually lead to people reporting problems to the filesystem
group who are in turn clueless what they mean.

Eventually someone finds me and I explain what is going on and that
these come from the audit system.  The basics of the problem is that the
audit subsystem never expects a single syscall to 'interact' (for some
wish washy meaning of interact) with more than 20 inodes.  But in fact
some operations like loading kernel modules can cause changes to lots of
inodes in debugfs.

There are a couple real fixes being bandied about including removing the
fixed compile time limit of 20 or not auditing changes in debugfs (or
both) but neither are small and obvious so I am not sending them for
immediate inclusion (I hope Al forwards a real solution next devel
window).

In the meantime this patch simply adds 'audit' to the beginning of the
crap message so if a user sees it, they come blame me first and we can
talk about what it means and make sure we understand all of the reasons
it can happen and make sure this gets solved correctly in the long run.

109f6aef5f Btrfs: add check for changed leaves in setup_leaf_for_split
setup_leaf_for_split needs to drop the path and search again, and has
checks to see if the item we want to split changed size.  But, it misses
the case where the leaf changed and now has enough room for the item
we want to insert.

This adds an extra check to make sure the leaf really needs splitting
before we call btrfs_split_leaf(), which keeps us from trying to split
a leaf with a single item.

btrfs_split_leaf() will blindly split the single item leaf, leaving us
with one good leaf and one empty leaf and then a crash.

6bdb72ded1 Btrfs: create snapshot references in same commit as snapshot
This creates the reference to a new snapshot in the same commit as the

snapshot to be persistent, and also avoids the problem of "leaking" a
new snapshot tree root if the host crashes before the second commit takes
place.

It is not at all clear to me why it wasn't always done this way.  If there
is still a reason for the two-stage {create,finish}_pending_snapshots()
approach I'm missing something!  :)

Everytime we start a new flushing thread, we init the waitqueue if there isn't a
flushing thread running.  The problem with this is we check
space_info->flushing, which we clear right before doing a wake_up on the
flushing waitqueue, which causes problems if we init the waitqueue in the middle
of clearing the flushing flagh and calling wake_up.  This is hard to hit, but
the code is wrong anyway, so init the flushing/allocating waitqueue when
creating the space info and let it be.  I haven't seen the panic since I've been
using this patch.  Thanks,

fails.

This bug also has the potential to leave behind anon_vma_chain structs
with pointers to invalid memory.

4dcc93d0ed ASoC: Don't use DCS_DATAPATH_BUSY for WM hubs devices
The DCS_DATAPATH_BUSY bit used to monitor the completion of DC servo
operations has been deprecated and with some more recente revisions
may perform incorrectly, especially when only analogue bypass paths
are in use. Switch to using readback from the DC servo command
register instead, which is supported for all devices. Without this
unacceptably long timeouts may be observed in some circumstances.

ae9d8607fe ASoC: Don't do runtime wm_hubs DC servo updates if using offset correction

8437f7006b ASoC: Support second DC servo readback method for wm_hubs
More recent Wolfson hubs devices add the ability to read back the DC
servo calibration information from the register used to write offsets,
and later still ones remove the old readback registers. Add support
for the new scheme, and use it for WM8994 device revisions that
support it.

1638bca898 ACPI: Reduce ACPI resource conflict message to KERN_WARNING, printk cleanup
By default, ACPI resource conflict messages are logged at level
KERN_ERR. This is a rather high level for a message that is more a
warning than an indication of a real kernel error. Also, KERN_ERR level
messages can appear over some boot splash screens, and this message is
not serious enough to warrant such treatment. Thus, the log level has
been reduced to KERN_WARNING.

[lenb changed to KERN_WARNING rather than all the way to KERN_INFO]

Also, cleanup message to use %pR resource printing format.

Disabling CONFIG_ACPI_SYSFS_POWER changes the behaviour of

even if the battery is not present.  I haven't noticed this
causing any problem, but it does look like a bad idea.
