We need to ensure that we do not send events to user space with the
identity address if we have not yet notified user space of the IRK. The
code was previously trying to handle this for the mgmt_pair_device
response (which worked well enough) but this is not the only connection
related event that might be sent to user space before pairing is
successful: another important event is Device Disconnected.
The issue can actually be solved more simply than the solution
previously used for mgmt_pair_device. Since we do have the identity
address tracked as part of the remote IRK struct we can just copy it
over from there to the hci_conn struct once we've for real sent the mgmt
event for the new IRK.

The watchdog thread waits on completion that is set from a timer. As
the completion is count based this could mean that on a busy system
the watchdog is handled multiple times with a very short interval.
This is not the intended behaviour. After handling the watchdog it
should wait for the next timer expiry. This is accomplished by
reinitializing the completion.

For non-mipsr2 processors, the local_irq_disable contains an mfc0-mtc0
pair with instructions inbetween. With preemption enabled, this sequence
may get preempted and effect a stale value of CP0_STATUS when executing
the mtc0 instruction. This commit avoids this scenario by incrementing
the preempt count before the mfc0 and decrementing it after the mtc9.

There are only two users of get_nohz_timer_target(): timer and hrtimer. Both
call it under same circumstances, i.e.
#ifdef CONFIG_NO_HZ_COMMON
if (!pinned && get_sysctl_timer_migration() && idle_cpu(this_cpu))
return get_nohz_timer_target();
#endif
So, it makes more sense to get all this as part of get_nohz_timer_target()
instead of duplicating code at two places. For this another parameter is
required to be passed to this routine, pinned.

This patch fixes flow control autonegotiation for KR/KX/K4 interfaces.
When setting up MAC link, the cached autoc value and current autoc value
were being incorrectly used to determine whether link reset is required.
This resulted in the driver ignoring and discarding flow control
negotiation changes that occur since the caching happened, as well as
when the mac was being setup.
This patch also splits the assignments for the 3 autoc variables into
their own block, and adds a comment explaining what each one means, in
order to help keep logic more straightforward while reading the code.

This is a temporary fix for some Intel HDMI codecs to avoid no sound output for
a resuming playback after S3.
After S3, the audio driver restores pin:cvt connection selections by
snd_hda_codec_resume_cache(). However this can happen before the gfx side is
ready and such connect selection is overlooked by HW. After gfx is ready, the
pins make the default selection again. And this will cause multiple pins share
a same convertor and mute control will affect each other. Thus a resumed audio
playback become silent after S3.
This patch verifies pin:cvt connection on preparing a stream, to assure the pin
selects the right convetor and an assigned convertor is not shared by other
unused pins. Apply this fix-up on Haswell, Broadwell and Valleyview (Baytrail).
We need this temporary fix before a reliable software communication channel is
established between audio and gfx, to sync audio/gfx operations.

For i350 VLAN stripping for VMs is not enabled in the VMOLR register but in
the DVMOLR register. Making the changes accordingly. It's not necessary to
unset the E1000_VMOLR_STRVLAN bit on i350 as the hardware will simply ignore
it.
Without this change if a VLAN is configured for a VF assigned to a guest
via (i.e.)
ip link set p1p1 vf 0 vlan 10
the VLAN tag will not be stripped from packets going into the VM. Which they
should be because the VM itself is not aware of the VLAN at all.

Intel Wired LAN Driver Updates
This series contains updates to i40e, i40evf, e1000e, ixgbe and ixgbevf.
Mitch adds support for the VF link state ndo which allows the PF driver
to control the virtual link state of the VF devices. Added
support for viewing and modifying RSS hash options and RSS hash look-up
table programming through ethtool for i40evf. Fixed complaint about
the use of min() where min_t() should be used in i40evf.
Anjali adds support for ethtool -k option for NTUPLE control for i40e.
Elizabeth cleans up and refactors i40e_open() to separate out the VSI
code into its own i40e_vsi_open().
Jesse enables the hardware feature head write back to avoid updating the
descriptor ring by marking each descriptor with a DD bit and instead
writes a memory location with an update to where the driver should clean
up to in i40e and i40evf. Reduces context descriptors for i40e/i40evf
since we do not need context descriptors for every packet, only for
TSO or timesync.
Dan Carpenter fixes a potential array underflow in i40e_vc_process_vf_msg().
Dave fixes an e1000e hardware unit hang where the check for pending Tx work
when link is lost was mistakenly moved to be done only when link is first
detected to be lost. Fixed a problem with poor network performance on
certain silicon in e1000e when configured for 100M HDX performance.
Carolyn adds register defines needed for time sync functions and the code
to call the updated defines.
Jacob adds the ixgbe function for writing PCI config word and checks
whether the adapter has been removed first.
Mark adds the bit __IXGBEVF_REMOVING to indicate that the module is being
removed because the __IXGBEVF_DOWN bit had been overloaded for this
purpose, but leads to trouble. ixgbevf_down function can now prevent
multiple executions by doing test_and_set_bit on __IXGBEVF_DOWN.
v2:
- dropped patch Mitch's patch "i40evf: Support RSS option in ethtool"
based on feedback from Ben Hutchings so that Mitch can re-work the
patch solution
v3:
- removed unnecessary parenthesis in patch 1 based on feedback from David
Miller
- changed a macro to get the next queue to a function in patch 2 based on
feedback from David Miller
- added blank lines after variable declaration and code in two functions
in patch 6 based on feedback from David Miller

If we do nothing in suspend/resume, some platform PCIe ip-block
can't guarantee the link back to L0 state from sleep, then, when
we read the EP device will hang. Only we send pme turnoff message
in pci controller suspend, and send pme exit message in resume, the
link state will be normal.
When we send pme turnoff message in pci controller suspend, the
links will into l2/l3 ready, then, host cannot communicate with
ep device, but pci-driver will call back EP device to save them
state. So we need to change platform_driver->suspend/resume to
syscore->suspend/resume.
So the new suspend/resume implementation, send pme turnoff message
in suspend, and send pme exit message in resume. And add a PME handler,
to response PME & message interrupt.
Change platform_driver->suspend/resume to syscore->suspend/resume.
pci-driver will call back EP device, to save EP state in
pci_pm_suspend_noirq, so we need to keep the link, until
pci_pm_suspend_noirq finish.
