As the VF infrastructure is supposed to offer backward/forward
compatibility, the various types associated with VF<->PF communication
should be aligned across all various platforms that support IOV
on our family of adapters.
This adds a couple of currently missing values, specifically aligning
the enum for the various TLVs possible in the communication between them.
It then adds the PF implementation for some of those missing VF requests.
This support isn't really necessary for the Linux VF as those VFs aren't
requiring it [at least today], but are required by VFs running on other
OSes. LRO is an example of one such configuration.

Up to this point, VF and PF communication always originates from VF.
As a result, VF cannot be notified of any async changes, and specifically
cannot be informed of the current link state.
This introduces the bulletin board, the mechanism through which the PF
is going to communicate async notifications back to the VF. basically,
it's a well-defined structure agreed by both PF and VF which the VF would
continuously poll and into which the PF would DMA messages when needed.
[Bulletin board is actually allocated and communicated in previous patches
but never before used]
Based on the bulletin infrastructure, the VF can query its link status
and receive said async carrier changes.

This adds sufficient changes to allow VFs l2-configuration flows to work.
While the fastpath of the VF and the PF are meant to be exactly the same,
the configuration of the VF is done by the PF.
This diverges all VF-related configuration flows that originate from a VF,
making them pass through the VF->PF channel and adding sufficient logic
on the PF side to support them.

While previous patches have already added the necessary logic to probe
VFs as well as enabling them in the HW, this patch adds the ability to
support VF FLR & SRIOV disable.
It then wraps both flows together into the first IOV callback to be
provided to the protocol driver - `configure'. This would later to be used
to enable and disable SRIOV in the adapter.

This adds the qed VFs for the first time -
The vfs are limited functions, with a very different PCI bar structure
[when compared with PFs] to better impose the related security demands
associated with them.
This patch includes the logic neccesary to allow VFs to successfully probe
[without actually adding the ability to enable iov].
This includes diverging all the flows that would occur as part of the pci
probe of the driver, preventing VF from accessing registers/memories it
can't and instead utilize the VF->PF channel to query the PF for needed
information.

Communication between VF and PF is based on a dedicated HW channel;
VF will prepare a messge, and by signaling the HW the PF would get a
notification of that message existance. The PF would then copy the
message, process it and DMA an answer back to the VF as a response.
The messages themselves are TLV-based - allowing easier backward/forward
compatibility.
This patch adds the infrastructure of the channel on the PF side -
starting with the arrival of the notification and ending with DMAing
the response back to the VF.
It also adds a dummy-response as reference, as it only lays the
groundwork of the communication; it doesn't really add support of any
actual messages.

Add detection and recovery code when the hardware returned opaque value
does not match the expected consumer index. Once the issue is detected,
we skip the processing of all RX and LRO/GRO packets. These completion
entries are discarded without sending the SKB to the stack and without
producing new buffers. The function will be reset from a workqueue.

There is a rare hardware bug that can cause a bad opaque value in the RX
or TPA completion. When this happens, the hardware may have used the
same buffer twice for 2 rx packets. In addition, the driver will also
crash later using the bad opaque as the index into the ring.
The rx opaque value is predictable and is always monotonically increasing.
The workaround is to keep track of the expected next opaque value and
compare it with the one returned by hardware during RX and TPA start
completions. If they miscompare, we will not process any more RX and
TPA completions and exit NAPI. We will then schedule a workqueue to
reset the function.
This patch adds the logic to keep track of the next rx consumer index.

NFC 4.7 pull request
This is the first NFC pull request for 4.7. With this one we
mainly have:
- Support for NXP's pn532 NFC chipset. The pn532 is based on the same
microcontroller as the pn533, but it talks to the host through i2c
instead of USB. By separating the pn533 driver into core and PHY
parts, we can not add the i2c layer and support the pn532 chipset.
- Support for NCI's loopback mode. This is a testing mode where each
packet received by the NFCC is sent back to the DH, allowing the
host to test that the controller can receive and send data.
- A few ACPI related fixes for the STMicro drivers, in order to match
the device tree naming scheme.
- A bunch of cleanups for the st-nci and the st21nfca STMicro drivers.

Currently the VRF driver uses the rx_handler to switch the skb device
to the VRF device. Switching the dev prior to the ip / ipv6 layer
means the VRF driver has to duplicate IP/IPv6 processing which adds
overhead and makes features such as retaining the ingress device index
more complicated than necessary.
This patch moves the hook to the L3 layer just after the first NF_HOOK
for PRE_ROUTING. This location makes exposing the original ingress device
trivial (next patch) and allows adding other NF_HOOKs to the VRF driver
in the future.
dev_queue_xmit_nit is exported so that the VRF driver can cycle the skb
with the switched device through the packet taps to maintain current
behavior (tcpdump can be used on either the vrf device or the enslaved
devices).

The core_pct_busy field of struct sample actually contains the
average performace during the last sampling period (in percent)
and not the utilization of the core as suggested by its name
which is confusing.
For this reason, change the name of that field to core_avg_perf
and rename the function that computes its value accordingly.
Also notice that storing this value as percentage requires a costly
integer multiplication to be carried out in a hot path, so instead
store it as an "extended fixed point" value with more fraction bits
and update the code using it accordingly (it is better to change the
name of the field along with its meaning in one go than to make those
two changes separately, as that would likely lead to more
confusion).

Currently, in intel_pstate_clear_update_util_hook(), after
clearing the utilization update hook, we leverage
synchronize_sched() to deal with synchronization, which
is a little bit time-costly because synchronize_sched()
has to wait for all the CPUs to go through a grace period.
Actually, the synchronize_sched() is not necessary if the utilization
update hook has not been set for the given CPU yet, so make the driver
check if that's the case and avoid the synchronize_sched() call then.

KVM/ARM Changes for Linux v4.7
Reworks our stage 2 page table handling to have page table manipulation
macros separate from those of the host systems as the underlying
hardware page tables can be configured to be noticably different in
layout from the stage 1 page tables used by the host.
Adds 16K page size support based on the above.
Adds a generic firmware probing layer for the timer and GIC so that KVM
initializes using the same logic based on both ACPI and FDT.
Finally adds support for hardware updating of the access flag.

ath.git patches for 4.7. Major changes:
ath6kl
* add ability to set debug uart baud rate with a module parameter
wil6210
* add debugfs file to configure firmware led functionality

Pull SCSI fixes from James Bottomley:
"This is a couple of small fixes: one is a potential uninitialised
error variable in the alua code, potentially causing spurious failures
and the other is a problem caused by the conversion of SCSI to
hostwide tags which resulted in the qla1280 driver always failing in
host initialisation"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
qla1280: Don't allocate 512kb of host tags
scsi_dh_alua: uninitialized variable in alua_rtpg()
