due to excessive synchronize_sched() invocations (Rafael Wysocki).
- Fix unnecessary invocations of WARN_ON() in the cpufreq core after

forgets to drop a reference to a DT node (Masahiro Yamada)"

Pull libnvdimm fixes from Dan Williams:
"1/ Two regression fixes since v4.6: one for the byte order of a sysfs
attribute (bz121161) and another for QEMU 2.6's NVDIMM _DSM (ACPI
Device Specific Method) implementation that gets tripped up by new
auto-probing behavior in the NFIT driver.
2/ A fix tagged for -stable that stops the kernel from
clobbering/ignoring changes to the configuration of a 'pfn'
instance ("struct page" driver). For example changing the
alignment from 2M to 1G may silently revert to 2M if that value is
currently stored on media.
3/ A fix from Eric for an xfstests failure in dax. It is not
currently tagged for -stable since it requires an 8-exabyte file
system to trigger, and there appear to be no user visible side
effects"

The default fallback function used by mlx5e select queue can return
any TX queues in range [0..dev->num_real_tx_queues).
The current implementation assumes that the fallback function returns
a number in the range [0.. number of channels). Actually
dev->num_real_tx_queues = (number of channels) * dev->num_tc;
which is more than the expected range if num_tc is configured and could
lead to crashes.
To fix this we test if num_tc is not configured we can safely return the
fallback suggestion, if not we will reciprocal_scale the fallback
result and normalize it to the desired range.

The current implementation does not handle timeout in case of command
with callback request, and this can lead to deadlock if the command
doesn't get fw response.
Add delayed callback timeout work before posting the command to fw.
In case of real fw command completion we will cancel the delayed work.
In case of fw command timeout the callback timeout handler will be
called and it will simulate fw completion with timeout error.

The device ID for VFs is in a different location than PFs. This results
in the poll always timing out for VFs. There's no good way to read the
VF device ID without using the PF's configuration space. Switch to waiting
for the health poll to start incrementing. Also remove the 1s sleep
at the beginning.

In internal error state the health poll thread will eventually call
synchronize_irq() (to safely trigger command completions) which might
sleep, so we are calling sleeping function from atomic context which is
invalid.
Here we move trigger_cmd_completions(dev) to enter error state which is
the earliest stage in error state handling.
This way we won't need to wait for next health poll to trigger command
completions and will solve the scheduling while atomic issue.
mlx5_enter_error_state can be called from two contexts, protect it with
dev->intf_state_lock

Pull MFD fixes from Lee Jones:
"Contained are some standard fixes and unusually an extension to the
Reset API. Some of those changes are required to fix a bug introduced
in -rc1, which introduces extra 'reset line checks' i.e. whether the
line is shared or not. If a line is shared and the new *_shared() API
is not used, the request fails with an error. This breaks USB in v4.7
for ST's platforms.
Admittedly, there are some patches contained in our (MFD/Reset)
immutable branch which are not true -fixes, but there isn't anything I
can do about that. Rest assured though, there aren't any API
'changes'. Everything is the same from the consumer's perspective.
- Use new reset_*_get_shared() variant to prevent reset line

Intel Wired LAN Driver Updates 2016-06-29
This series contains fixes to e1000e and ixgbevf.
Jarod Wilson's fix for e1000e was a follow-on patch to his previous fix to
keep the hardware VLAN CTAG's for receive and transmit in sync, which
in turn resolves the original issue, so revert a portion of the original
fix.
Xin Long noticed that the ret_val needed to be initialized to IXGBE_ERR_MBX,
instead of -IXGBE_ERR_MBX.

When configuring FPS during probe, assuming a DT node is present for
FPS, the code can run into a problem with the switch statements in
max77620_config_fps() and max77620_get_fps_period_reg_value(). Namely,
in the case of chip->chip_id == MAX77620, it will set
fps_[mix|max]_period but then fall through to the default switch case
and return -EINVAL. Returning this from max77620_config_fps() will
cause probe to fail.

Per JEDEC Annex L Release 3 the SPD data is:
Bits 9~5 00 000 = Function Undefined
00 001 = Byte addressable energy backed
00 010 = Block addressed
00 011 = Byte addressable, no energy backed
All other codes reserved
Bits 4~0 0 0000 = Proprietary interface
0 0001 = Standard interface 1
All other codes reserved; see Definitions of Functions
...and per the ACPI 6.1 spec:
byte0: Bits 4~0 (0 or 1)
byte1: Bits 9~5 (1, 2, or 3)
...so a format interface code displayed as 0x301 should be stored in the
nfit as (0x1, 0x3), little-endian.

and checking for valid regulator information data before

NULL pointer exception if regulator not registered with core.

Uncompleted reqs used to be 'saved and resubmitted' in blkfront_recover() during
migration, but that's too late after multi-queue was introduced.
After a migrate to another host (which may not have multiqueue support), the
number of rings (block hardware queues) may be changed and the ring and shadow
structure will also be reallocated.
The blkfront_recover() then can't 'save and resubmit' the real
uncompleted reqs because shadow structure have been reallocated.
This patch fixes this issue by moving the 'save' logic out of
blkfront_recover() to earlier place in blkfront_resume().
The 'resubmit' is not changed and still in blkfront_recover().
