Here are a number of USB patches, a bit more than I normally like this
 late in the -rc series, but given people's vacations (myself included),
 and the kernel summit, it seems to have happened this way.
 
 All are tiny, but they add up.  A number of gadget and xhci fixes, and a
 few new device ids.  All have been tested in linux-next.

55815f7014 vfs: make O_PATH file descriptors usable for 'fstat()'
We already use them for openat() and friends, but fstat() also wants to
be able to use O_PATH file descriptors.  This should make it more
directly comparable to the O_SEARCH of Solaris.

Note that you could already do the same thing with "fstatat()" and an
empty path, but just doing "fstat()" directly is simpler and faster, so
there is no reason not to just allow it directly.

See also commit 332a2e1244, which did the same thing for fchdir, for
the same reasons.

f25b70613c ACPI / PM: Use KERN_DEBUG when no power resources are found
commit a606dac368 adds support to link
devices which have _PRx, if a device does not have _PRx, a warning
message will be printed.

This commit is for ZPODD on Intel ZPODD capable platforms, on other
platforms, it has no problem if there is no power resource for this
device, so a warning here is not appropriate, change it to debug.

8335eafc28 eCryptfs: Copy up attributes of the lower target inode after rename
After calling into the lower filesystem to do a rename, the lower target
inode's attributes were not copied up to the eCryptfs target inode. This
resulted in the eCryptfs target inode staying around, rather than being
evicted, because i_nlink was not updated for the eCryptfs inode. This
also meant that eCryptfs didn't do the final iput() on the lower target
inode so it stayed around, as well. This would result in a failure to
free up space occupied by the target file in the rename() operation.
Both target inodes would eventually be evicted when the eCryptfs
filesystem was unmounted.

This patch calls fsstack_copy_attr_all() after the lower filesystem
does its ->rename() so that important inode attributes, such as i_nlink,
are updated at the eCryptfs layer. ecryptfs_evict_inode() is now called
and eCryptfs can drop its final reference on the lower inode.

64e6651dcc eCryptfs: Call lower ->flush() from ecryptfs_flush()
Since eCryptfs only calls fput() on the lower file in
ecryptfs_release(), eCryptfs should call the lower filesystem's
->flush() from ecryptfs_flush().

If the lower filesystem implements ->flush(), then eCryptfs should try
to flush out any dirty pages prior to calling the lower ->flush(). If
the lower filesystem does not implement ->flush(), then eCryptfs has no
need to do anything in ecryptfs_flush() since dirty pages are now
written out to the lower filesystem in ecryptfs_release().

7149f2558d eCryptfs: Write out all dirty pages just before releasing the lower file
Fixes a regression caused by:

821f749 eCryptfs: Revert to a writethrough cache model

That patch reverted some code (specifically, 32001d6f) that was
necessary to properly handle open() -> mmap() -> close() -> dirty pages
-> munmap(), because the lower file could be closed before the dirty
pages are written out.

Rather than reapplying 32001d6f, this approach is a better way of
ensuring that the lower file is still open in order to handle writing
out the dirty pages. It is called from ecryptfs_release(), while we have
a lock on the lower file pointer, just before the lower file gets the
final fput() and we overwrite the pointer.

40bf66ec97 ACPI / PM: Fix resource_lock dead lock in acpi_power_on_device
Commit 0090def("ACPI: Add interface to register/unregister device
to/from power resources") used resource_lock to protect the devices list
that relies on power resource. It caused a mutex dead lock, as below

    acpi_power_on ---> lock resource_lock
      __acpi_power_on
        acpi_power_on_device
          acpi_power_get_inferred_state
            acpi_power_get_list_state ---> lock resource_lock

This patch adds a new mutex "devices_lock" to protect the devices list
and calls acpi_power_on_device in acpi_power_on, instead of
__acpi_power_on, after the resource_lock is released.

8f7412a792 ACPI / PM: Infer parent power state from child if unknown, v2
It turns out that there are ACPI BIOSes defining device objects with
_PSx and without either _PSC or _PRx.  For devices corresponding to
those ACPI objetcs __acpi_bus_get_power() returns ACPI_STATE_UNKNOWN
and their initial power states are regarded as unknown as a result.
If such a device is a parent of another power-manageable device, the
child cannot be put into a low-power state through ACPI, because
__acpi_bus_set_power() refuses to change power states of devices
whose parents' power states are unknown.

To work around this problem, observe that the ACPI power state of
a device cannot be higher-power (lower-number) than the power state
of its parent.  Thus, if the device's _PSC method or the
configuration of its power resources indicates that the device is
in D0, the device's parent has to be in D0 as well.  Consequently,
if the parent's power state is unknown when we've just learned that
its child's power state is D0, we can safely set the parent's
power.state field to ACPI_STATE_D0.

7b5342d902 bnx2x: Add missing afex code
Commit a334872224 added afex support but lacked
several logical changes. This lack can cause afex to crash, and also
have a slight effect on other flows (i.e., driver always assumes the Tx ring
has less available buffers than what it actually has).

This patch adds the missing segments, fixing said issues.

217aeb896a bnx2x: fix stats copying logic
FW needs the driver statistics for management. Current logic is broken
in that the function that gathers the port statistics does not copy
its own statistics to a place where the FW can use it.

f492c171a3 drm/radeon: make 64bit fences more robust v3
Only increase the higher 32bits if we really detect a wrap around.

v2: instead of increasing the higher 32bits just use the higher
    32bits from the last emitted fence.
v3: also use last emitted fence value as upper limit.

The intention of this patch is to make fences as robust as
they where before introducing 64bit fences. This is
necessary because on older systems it looks like the fence
value gets corrupted on initialization.

Fixes:
https://bugs.freedesktop.org/show_bug.cgi?id=51344

Should also fix:

https://bugzilla.redhat.com/show_bug.cgi?id=846505

3.5 needs a separate patch due to changes in the
fence code.  Will send that out separately.

985f61f7ee drm/radeon: rework pll selection (v3)
For DP we can use the same PPLL for all active DP
encoders.  Take advantage of that to prevent cases
where we may end up sharing a PPLL between DP and
non-DP which won't work.  Also clean up the code
a bit.

v2: - fix missing pll_id assignment in crtc init
v3: - fix DP PPLL check
    - document functions
    - break in main encoder search loop after matching.
      no need to keep checking additional encoders.

8624dd2a3e net: qmi_wwan: call subdriver with control intf only
This fixes a hang on suspend due to calling wdm_suspend on
the unregistered data interface. The hang should have been
a NULL pointer reference had it not been for a logic error
in the cdc_wdm code.

  commit 230718bd net: qmi_wwan: bind to both control and data interface

changed qmi_wwan to use cdc_wdm as a subdriver for devices with
a two-interface QMI/wwan function.  The commit failed to update
qmi_wwan_suspend and qmi_wwan_resume, which were written to handle
either a single combined interface function, or no subdriver at all.

The result was that we called into the subdriver both when the
control interface was suspended and when the data interface was
suspended.  Calling the subdriver suspend function with an
unregistered interface is not supported and will make the
subdriver bug out.

ba1bf474ea net_sched: gred: actually perform idling in WRED mode
gred_dequeue() and gred_drop() do not seem to get called when the
queue is empty, meaning that we never start idling while in WRED
mode. And since qidlestart is not stored by gred_store_wred_set(),
we would never stop idling while in WRED mode if we ever started.
This messes up the average queue size calculation that influences
packet marking/dropping behavior.

Now, we start WRED mode idling as we are removing the last packet
from the queue. Also we now actually stop WRED mode idling when we
are enqueuing a packet.

1fe37b106b net_sched: gred: fix qave reporting via netlink
q->vars.qavg is a Wlog scaled value, but q->backlog is not. In order
to pass q->vars.qavg as the backlog value, we need to un-scale it.
Additionally, the qave value returned via netlink should not be Wlog
scaled, so we need to un-scale the result of red_calc_qavg().

This caused artificially high values for "Average Queue" to be shown
by 'tc -s -d qdisc', but did not affect the actual operation of GRED.

4312a7ef9c ARM: msm: Allow timer.c to compile on multiple targets
The timer code relies on #defines from mach/iomap.h, cpu_is_*()
checks, and a global irq #define. All this makes this file
impossible to compile in a mult-target build. Therefore, make a
sys_timer struct for each SoC so that machine descriptors can
reference the correct timer. Then go through and replace all the
defines with raw values that are passed to a common
initialization function.

This paves the way to adding DT support to this code as well as
allows us to compile this file on multiple targets at the same
time.
