      Pull vfs dentry reference count fix from Al Viro.

This fixes a possible inode_permission NULL pointer dereference (and
other problems) that were due to the root dentry count being decremented
too much.  In commit 48a066e7 ("RCU'd vfsmounts") the placement of
clearing the LOOKUP_RCU bit changed, and we then returned failure of
incrementing the lockref on the parent dentry with LOOKUP_RCU cleared.

But that meant we needed to go through the same cleanup routines that
the later failures did wrt LOOKUP_ROOT and nd->root.

      Al Viro authored 
      Failure to grab reference to parent dentry should go through the
same cleanup as nd->seq mismatch.  As it is, we might end up with
caller thinking it needs to path_put() nd->root, with obvious
nasty results once we'd hit that bug enough times to drive the
refcount of root dentry all the way to zero...

      Greg Kroah-Hartman authored 
      This reverts commit 54d71145.

The root cause of these "inverted" sysfs removals have now been found,
so there is no need for this patch.  Keep this functionality around so
that this type of error doesn't show up in driver code again.

      Greg Kroah-Hartman authored 
      There seems to be no active maintainer for the driver, and there is an
unfixed security bug, so disable the driver for now.

Hopefully someone steps up to be the maintainer, and works to get this
out of staging, otherwise it will be deleted soon.

      ALSA: hda - Create Headhpone Mic Jack Mode when really needed · ced4cefc
      Takashi Iwai authored 
      When a headphone jack is configurable as input, the generic parser
tries to make it retaskable as Headphone Mic.  The switching can be
done smoothly if Capture Source control exists (i.e. there is another
input source).  Or when user explicitly enables the creation of jack
mode controls, "Headhpone Mic Jack Mode" will be created accordingly.

However, if the headphone mic is the only input source, we have to
create "Headphone Mic Jack Mode" control because there is no capture
source selection.  Otherwise, the generic parser assumes that the
input is constantly enabled, thus the headphone is permanently set
as input.  This situation happens on the old MacBook Airs where no
input is supported properly, for example.

This patch fixes the problem: now "Headphone Mic Jack Mode" is created
when such an input selection isn't possible.

      gpio: pl061: move irqdomain initialization · 2ba3154d
      Linus Walleij authored 
      The PL061 driver had the irqdomain initialization in an unfortunate
place: when used with device tree (and thus passing the base IRQ
0) the driver would work, as this registers an irqdomain and waits
for mappings to be done dynamically as the devices request their
IRQs, whereas when booting using platform data the irqdomain core
would attempt to allocate IRQ descriptors dynamically (which works
fine) but also to associate the irq_domain_associate_many() on all
IRQs, which in turn will call the mapping function which at this
point will try to set the type of the IRQ and then tries to acquire
a non-initialized spinlock yielding a backtrace like this:

 r4:c0464380

This moves the irqdomain initialization to a point where the spinlock
and GPIO chip are both fully propulated, so the callbacks can be used
without crashes.

I had some problem reproducing the crash, as the devm_kzalloc():ed
zeroed memory would seemingly mask the spinlock as something OK,
but by poisoning the lock like this:

u32 *dum;
dum = (u32 *) &chip->lock;
*dum = 0xaaaaaaaaU;

I could reproduce, fix and test the patch.

limit in WUSB.

      UHID allows short writes so user-space can omit unused fields. We
automatically set them to 0 in the kernel. However, the 64/32 bit
compat-handler didn't do that in the UHID_CREATE fallback. This will
reveal random kernel heap data (of random size, even) to user-space.

      Most Thinkpad Edge series laptops use conexant codec, so far although
the codecs have different minor Vendor Id and minor Subsystem Id,
they all belong to the cxt5066 family, this change can make the
mute/mic-mute LEDs support more generic among cxt_5066 family.

This design refers to the similar solution for the realtek codec
ALC269 family in the patch_realtek.c.

Pull tracing fixes from Steven Rostedt:
 "This includes two fixes.

  1) is a bug fix that happens when root does the following:

     echo function_graph > current_tracer
     modprobe foo
     echo nop > current_tracer

   This causes the ftrace internal accounting to get screwed up and
   crashes ftrace, preventing the user from using the function tracer
   after that.

  2) if a TRACE_EVENT has a string field, and NULL is given for it.

   The internal trace event code does a strlen() and strcpy() on the
   source of field.  If it is NULL it causes the system to oops.

   This bug has been there since 2.6.31, but no TRACE_EVENT ever passed
   in a NULL to the string field, until now"
