a7f12a21f6 usb: phy: isp1301: Fix build warning when CONFIG_OF is disabled
Commit fd567653bd ("usb: phy: isp1301: Add OF device ID table")
added an OF device ID table, but used the of_match_ptr() macro
that will lead to a build warning if CONFIG_OF symbol is disabled:

d3519b9d96 xhci: Manually give back cancelled URB if we can't queue it for cancel
xhci needs to take care of four scenarios when asked to cancel a URB.

1 URB is not queued or already given back.
  usb_hcd_check_unlink_urb() will return an error, we pass the error on

2 We fail to find xhci internal structures from urb private data such as
  virtual device and endpoint ring.
  Give back URB immediately, can't do anything about internal structures.

3 URB private data has valid pointers to xhci internal data, but host is
  not  responding.
  give back URB immedately and remove the URB from the endpoint lists.

4 Everyting is working
  add URB to cancel list, queue a command to stop the endpoint, after
  which the URB can be turned to no-op or skipped, removed from lists,
  and given back.

We failed to give back the urb in case 2 where the correct device and
endpoint pointers could not be retrieved from URB private data.

This caused a hang on Dell Inspiron 5558/0VNM2T at resume from suspend
as urb was never returned.

0ab2881a40 xhci: Set URB actual length for stopped control transfers
A control transfer that stopped at the status stage incorrectly
warned about a "unexpected TRB Type 4", and did not set the

The URB actual_length for control transfers should contain the

Bytes of a partially sent setup stage and missing bytes from

61b79e16c6 ACPI: Fix incompatibility with mcount-based function graph tracing
Paul Menzel reported a warning:

  WARNING: CPU: 0 PID: 774 at /build/linux-ROBWaj/linux-4.9.13/kernel/trace/trace_functions_graph.c:233 ftrace_return_to_handler+0x1aa/0x1e0
  Bad frame pointer: expected f6919d98, received f6919db0
    from func acpi_pm_device_sleep_wake return to c43b6f9d

The warning means that function graph tracing is broken for the
acpi_pm_device_sleep_wake() function.  That's because the ACPI Makefile
unconditionally sets the '-Os' gcc flag to optimize for size.  That's an
issue because mcount-based function graph tracing is incompatible with
'-Os' on x86, thanks to the following gcc bug:

  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=42109

I have another patch pending which will ensure that mcount-based
function graph tracing is never used with CONFIG_CC_OPTIMIZE_FOR_SIZE on
x86.

But this patch is needed in addition to that one because the ACPI
Makefile overrides that config option for no apparent reason.  It has
had this flag since the beginning of git history, and there's no related
comment, so I don't know why it's there.  As far as I can tell, there's
no reason for it to be there.  The appropriate behavior is for it to
honor CONFIG_CC_OPTIMIZE_FOR_{SIZE,PERFORMANCE} like the rest of the
kernel.

9646b26e85 virtio-balloon: use actual number of stats for stats queue buffers
The virtio balloon driver contained a not-so-obvious invariant that
update_balloon_stats has to update exactly VIRTIO_BALLOON_S_NR counters
in order to send valid stats to the host. This commit fixes it by having
update_balloon_stats return the actual number of counters, and its
callers use it when pushing buffers to the stats virtqueue.

Note that it is still out of spec to change the number of counters
at run-time. "Driver MUST supply the same subset of statistics in all
buffers submitted to the statsq."

fc8653228c virtio_balloon: init 1st buffer in stats vq
When init_vqs runs, virtio_balloon.stats is either uninitialized or
contains stale values. The host updates its state with garbage data
because it has no way of knowing that this is just a marker buffer
used for signaling.

This patch updates the stats before pushing the initial buffer.

Alternative fixes:
* Push an empty buffer in init_vqs. Not easily done with the current
  virtio implementation and violates the spec "Driver MUST supply the
  same subset of statistics in all buffers submitted to the statsq".
* Push a buffer with invalid tags in init_vqs. Violates the same
  spec clause, plus "invalid tag" is not really defined.

Note: the spec says:
	When using the legacy interface, the device SHOULD ignore all values in
	the first buffer in the statsq supplied by the driver after device
	initialization. Note: Historically, drivers supplied an uninitialized
	buffer in the first buffer.

Unfortunately QEMU does not seem to implement the recommendation
even for the legacy interface.

8d40b0f148 NFS filelayout:call GETDEVICEINFO after pnfs_layout_process completes
Fix a filelayout GETDEVICEINFO call hang triggered from the LAYOUTGET
pnfs_layout_process where the GETDEVICEINFO call is waiting for a
session slot, and the LAYOUGET call is waiting for pnfs_layout_process
to complete before freeing the slot GETDEVICEINFO is waiting for..

This occurs in testing against the pynfs pNFS server where the
the on-wire reply highest_slotid and slot id are zero, and the
target high slot id is 8 (negotiated in CREATE_SESSION).

The internal fore channel slot table max_slotid, the maximum allowed
table slotid value, has been reduced via nfs41_set_max_slotid_locked
 from 8 to 1.  Thus there is one slot (slotid 0) available for use but
it has not been freed by LAYOUTGET  proir to the GETDEVICEINFO request.

In order to ensure that layoutrecall callbacks are processed in the
correct order, nfs4_proc_layoutget processing needs to be finished
e.g. pnfs_layout_process) before giving up the slot that identifies
the layoutget (see referring_call_exists).

Move the filelayout_check_layout nfs4_find_get_device call outside of
the pnfs_layout_process call tree.

fpfn == 0. If VRAM is almost full, the first VRAM placement with
fpfn > 0 may not work, but the second one with fpfn == 0 always will
(the BO's current location trivially satisfies it). Because "moving"
the BO to its current location puts it back on the LRU list, this
results in an infinite loop.

2f0ba790df cpufreq: Fix creation of symbolic links to policy directories
The cpufreq core only tries to create symbolic links from CPU
directories in sysfs to policy directories in cpufreq_add_dev(),
either when a given CPU is registered or when the cpufreq driver
is registered, whichever happens first.  That is not sufficient,
however, because cpufreq_add_dev() may be called for an offline CPU
whose policy object has not been created yet and, quite obviously,
the symbolic cannot be added in that case.

Fix that by making cpufreq_online() attempt to add symbolic links to
policy objects for the CPUs in the related_cpus mask of every new
policy object created by it.

The cpufreq_driver_lock locking around the for_each_cpu() loop
in cpufreq_online() is dropped, because it is not necessary and the
code is somewhat simpler without it.  Moreover, failures to create
a symbolic link will not be regarded as hard errors any more and
the CPUs without those links will not be taken offline automatically,
but that should not be problematic in practice.

Now that nfs_rename()'s d_move has moved within the RPC task's rpc_call_done

in nfs_rename().  d_move() is going to rehash the new dentry for us anyway,

0abfe7e257 drm/i915: Restore marking context objects as dirty on pinning
Commit e8a9c58fcd ("drm/i915: Unify active context tracking between
legacy/execlists/guc") converted the legacy intel_ringbuffer submission
to the same context pinning mechanism as execlists - that is to pin the
context until the subsequent request is retired. Previously it used the
vma retirement of the context object to keep itself pinned until the
next request (after i915_vma_move_to_active()). In the conversion, I
missed that the vma retirement was also responsible for marking the
object as dirty. Mark the context object as dirty when pinning
(equivalent to execlists) which ensures that if the context is swapped
out due to mempressure or suspend/hibernation, when it is loaded back in
it does so with the previous state (and not all zero).

7b09cc5a9d sched/clock: Fix broken stable to unstable transfer
When it is determined that the clock is actually unstable, and
we switch from stable to unstable, the __clear_sched_clock_stable()
function is eventually called.

In this function we set gtod_offset so the following holds true:

  sched_clock() + raw_offset == ktime_get_ns() + gtod_offset

But instead of getting the latest timestamps, we use the last values
from scd, so instead of sched_clock() we use scd->tick_raw, and
instead of ktime_get_ns() we use scd->tick_gtod.

However, later, when we use gtod_offset sched_clock_local() we do not
add it to scd->tick_gtod to calculate the correct clock value when we
determine the boundaries for min/max clocks.

This can result in tick granularity sched_clock() values, so fix it.

buffer allocation fails, the routine returns immediately without
