77b2f28659 iwlwifi: mvm: disable scheduled scan to prevent firmware crash
There are firmwares which don't support scheduled scan.
Disable it for now.
Linus's system encoutered this issue.
Thanks to David Spinadel for his help.

582d67f0b1 drm/i915: Add temporary ring->ctx backpointer
The execlist patches have a bit a convoluted and long history and due
to that have the actual submission still misplaced deeply burried in
the low-level ringbuffer handling code. This design goes back to the
legacy ringbuffer code with its tricky lazy request and simple work
submissiion using ring tail writes. For that reason they need a
ring->ctx backpointer.

The goal is to unburry that code and move it up into a level where the
full execlist context is available so that we can ditch this
backpointer. Until that's done make it really obvious that there's
work still to be done.

1d508f8ace Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull more powerpc updates from Ben Herrenschmidt:
 "Here are some more powerpc bits for 3.17, essentially fixes.

  The biggest series, also aimed at -stable, is from Aneesh and is the
  result of weeks and weeks of debugging to find out why the heck or THP
  implementation was occasionally triggering multi-hit errors in our
  level 1 TLB.  It ended up being a combination of issues including
  subtleties as to how we should invalidate those special 'MPSS' pages
  we use to allow the use of 16M pages inside 4K/64K "base page size"
  segments (you really have to love our MMU !)

  Another interesting one in the "OMG" category is the series from
  Michael adding memory barriers to spin_is_locked().  That's also the
  result of many days of debugging to figure out why the semaphore code
  would occasionally crash in ways that made no sense.  It ended up
  being some creative lock stacking that was defeated by the fact that
  our locks allow a load inside the locked section to be re-ordered with
  the load of the lock value itself (I'm still of two mind about whether
  to kill that once and for all by putting a heavier barrier back into
  our lock implementation...).  The fixes come with a long explanation
  in the cset comments, feel free to read it if you feel like having a
  headache today"

ae36e95cf8 The branch contains the following device tree changes the v3.17 merge
window:
 
 Group changes to the device tree. In preparation for adding device tree
 overlay support, OF_DYNAMIC is reworked so that a set of device tree
 changes can be prepared and applied to the tree all at once. OF_RECONFIG
 notifiers see the most significant change here so that users always get
 a consistent view of the tree. Notifiers generation is moved from before
 a change to after it, and notifiers for a group of changes are emitted
 after the entire block of changes have been applied
 
 Automatic console selection from DT. Console drivers can now use
 of_console_check() to see if the device node is specified as a console
 device. If so then it gets added as a preferred console. UART devices
 get this support automatically when uart_add_one_port() is called.
 
 DT unit tests no longer depend on pre-loaded data in the device tree.
 Data is loaded dynamically at the start of unit tests, and then unloaded
 again when the tests have completed.
 
 Also contains a few bugfixes for reserved regions and early memory setup.

This is happening since wake is not enabled and Gunit registers are not restored.
For this system suspend/resume paths need to follow save/restore and additional
platform specific setup in suspend_complete and resume_prepare.

suspend_complete is shared unconditionaly for VLV, HSW, BDW. resume_prepare for
HSW and BDW has pc8 disabling which is needed during thaw_early so sharing
uncondtionally. For VLV and SNB runtime resume specific sequence exists.

ed9814d858 locks: defer freeing locks in locks_delete_lock until after i_lock has been dropped
In commit 72f98e7255 (locks: turn lock_flocks into a spinlock), we
moved from using the BKL to a global spinlock. With this change, we lost
the ability to block in the fl_release_private operation.

This is problematic for NFS (and probably some other filesystems as
well). Add a new list_head argument to locks_delete_lock. If that
argument is non-NULL, then queue any locks that we want to free to the
list instead of freeing them.

Then, add a new locks_dispose_list function that will walk such a list
and call locks_free_lock on them after the i_lock has been dropped.

Finally, change all of the callers of locks_delete_lock to pass in a
list_head, except for lease_modify. That function can be called long
after the i_lock has been acquired. Deferring the freeing of a lease
after unlocking it in that function is non-trivial until we overhaul
some of the spinlocking in the lease code.

Currently though, no filesystem that sets fl_release_private supports
leases, so this is not currently a problem. We'll eventually want to
make the same change in the lease code, but it needs a lot more work
before we can reasonably do so.

b84d49f944 locks: don't reuse file_lock in __posix_lock_file
Currently in the case where a new file lock completely replaces the old
one, we end up overwriting the existing lock with the new info. This
means that we have to call fl_release_private inside i_lock. Change the
code to instead copy the info to new_fl, insert that lock into the
correct spot and then delete the old lock. In a later patch, we'll defer
the freeing of the old lock until after the i_lock has been dropped.

been removed recursively by mac/cfg80211, and spectral tries to remove

OK, no LoC saved in this case because the !return variants were
defined in terms of the return ops. Still do it because this also
prepares for easy addition of new ops.

Requires the asm_op because of eor.

AVR32 is a bit special in that its ADD/SUB instructions are not
symmetric. Its SUB instruction allows for an 21bit immediate.

daebdd7ee3 HID: rmi: print an error if F11 is not found instead of stopping the device
Currently rmi_probe will return -EIO if the device doesn't report that it has F11.
This would indicate that something happened and the device is in the bootloader.
We can recover the device using a userspace firmware update tool, but it needs
access to the device through the hidraw device file. If the probe returns -EIO
the hidraw device won't be created. So instead of failing the probe, just print
an error message, but leave the device accessible from userspace.

61074c1a2d ALSA: hda - Set TLV_DB_SCALE_MUTE bit for cx5051 vmaster
Conexnat HD-audio driver has a workaround for cx5051 (aka CX20561)
chip to add fake mute controls to each amp (commit 3868137e).  This
implies the minimum-as-mute TLV bit in TLV for each corresponding
control.  Meanwhile we build the virtual master from these, but the
TLV bit is missing, even though the slaves have it.

This patch simply adds the missing TLV_DB_SCALE_MUTE bit for vmaster,
as already done in patch_sigmatel.c.

These syscalls are not used by userspace tools for some time now, and
they have issues when called with invalid arguments. It's not worth
changing signal delivery mechanism as we don't expect any new users for
these syscalls. Let's keep them for backwards compatibility under #ifdef,
disabled by default.
