The pm_rumtime work queue is causing the device to be suspended during
initialisation, thus the initialisation may not be able to access registers
properly. As the code is called from a work queue, it is possible that this
is not seen from certain configurations/builds due to the asynchronos
nature of the code.
Another issue has also been found where the network device registration
calls back into the driver thus causing further pm_runtime calls that
also caused issues with the MDIO bus code. This has now been checked
and is the only place the MDIO can be called without the device open.
Use pm_runtime_get_sync() and pm_runtime_put() to ensure that the
pm system does not suspend it during the probe() call and remove the
now unnecessary pm_runtime_resume() call. Also add a call in the error
path to call pm_runtime_disable().
This fixes the external abort that can cause /sbin/init or other such
init processed to die.

tipc: fix handling of NETDEV_CHANGEADDR event
Aside from manual reconfiguration of the netdevice hwaddr, this can also
be changed automatically for an interface bond in active-backup mode
if fail_over_mac is enabled. This patchset fixes the handling of this
event in TIPC by properly updating the l2 media address for the bearer,
followed by a reinitialization of the node discovery mechanism.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The node discovery domain is assigned when a bearer is enabled.
In the previous commit we reflect this attribute directly in the
bearer structure since it's needed to reinitialize the node
discovery mechanism after a hardware address change.
There's no need to replicate this attribute anywhere else, so we
remove it from the tipc_link_req structure.

Intel Wired LAN Driver Updates
This series contains updates to e1000e, igb, i40e and i40evf
Anjali provides i40e fix to remove the ATR filter on RST as well as FIN
packets. Cleans up add_del_fdir() because it was used and implemented
only for the add, so change the name and drop a parameter. Adds the
ability to drop a flow if we wanted to and adds a flow director
message level to be used for flow director specific messages.
Mitch fixes an issue on i40evf where the Tx watchdog handler was causing
an oops when sending an admin queue message to request a reset because
the admin queue functions use spinlocks.
Greg provides a change to i40e to make the alloc and free queue vector
calls orthogonal.
Shannon fixes i40e to verify the eeprom checksum and firmware CRC status
bits, and shutdown the driver if they fail. This change stops the
processing of traffic, but does not kill the PF netdev so that the
NVMUpdate process still has a chance at fixing the image. Also provides
a fix to make sure the VSI has a netdev before trying to use it in
the debugfs netdev_ops commands.
Jakub Kicinski provides patches for e1000e and igb to fix a number issues
found in the PTP code.

Broadwell introduces large address spaces, greater than 32bits in width.
These require that we then store and print 64bit values. If we were to
zero pad them out to 16 hexadecimal places, we have to carefully count
the leading zeroes - which is easy to make a mistake. Conversely, if we
do not zero pad out to 16, but keep it padding to 8 hexadecimal places,
it is very easy to miss an address that is actually larger than 4GiB. A
suggested compromise is to insert a space between the upper and lower
dwords of the address so that we can continue with our accustom 32bit
parser. (Alternatively, we could do the equivalent in our userspace
decoder.)

As Broadwell has an increased virtual address size, it requires more
than 32 bits to store offsets into its address space. This includes the
debug registers to track the current HEAD of the individual rings, which
may be anywhere within the per-process address spaces. In order to find
the full location, we need to read the high bits from a second register.
We then also need to expand our storage to keep track of the larger
address.
v2: Carefully read the two registers to catch wraparound between
the reads.
v3: Use a WARN_ON rather than loop indefinitely on an unstable
register read.

There's an entire pile of issues in here:
- Use the main RING_HEAD register, not ACTHD. ACTHD points at the gtt
offset of the batch buffer when a batch is executed. Semaphores are
always emitted to the main ring, so we always want to look at that.
- Mask the obtained HEAD pointer with the actual ring size, which is
much smaller. Together with the above issue this resulted us in
trying to dereference a pointer way outside of the ring mmio
mapping. The resulting invalid access in interrupt context
(hangcheck is executed from timers) lead to a full blown kernel
panic. The fbcon panic handler then tried to frob our driver harder,
resulting in a full machine hang at least on my snb here where I've
stumbled over this.
- Handle ring wrapping correctly and be a bit more explicit about how
many dwords we're scanning. We probably should also scan more than
just 4 ...
- Space out some of teh computations for readability.
This reduces hard-hangs on my snb here. Mika and QA both say that it
doesn't completel remove them, but at least for me it's a clear
improvement in stability.

Now since this is init code locking is fairly redudant if it wouldn't
be for the drm core registering sysfs files a bit early. And the
locking WARNINGs nicely enforce that indeed all access to the mode
lists are properly protected. And a full audit shows that only i915

The new Lenovo Haswell series (-40's) contains a new Synaptics touchpad.
However, these new Synaptics devices report bad axis ranges.
Under Windows, it is not a problem because the Windows driver uses RMI4
over SMBus to talk to the device. Under Linux, we are using the PS/2
fallback interface and it occurs the reported ranges are wrong.
Of course, it would be too easy to have only one range for the whole
series, each touchpad seems to be calibrated in a different way.
We can not use SMBus to get the actual range because I suspect the firmware
will switch into the SMBus mode and stop talking through PS/2 (this is the
case for hybrid HID over I2C / PS/2 Synaptics touchpads).
So as a temporary solution (until RMI4 land into upstream), start a new
list of quirks with the min/max manually set.

Function add_del_fdir was used and implemented only for add. So change the name
and drop a parameter.

The driver needs to verify the eeprom checksum and firmware crc status bits,
and shutdown the driver if they fail. This code stops the processing of traffic,
but doesn't kill the PF netdev so that the NVMUpdate process should still have a
chance at fixing the image. The eeprom is checked on driver load and after an
EMP reset, the latter of which should be generated after an NVMUpdate.

It's annoying to search for a matching alloc and free set of function calls
when they don't use the same framework for the name of the functions. Fix
that up in the case of alloc and free of vsi queue vectors.
i40e_vsi_free_q*
i40e_vsi_alloc_q*

The Tx watchdog handler runs in interrupt context, so it would cause an
oops when sending an admin queue message to request a reset, because the
admin queue functions use spinlocks.
Instead, set a flag and let the reset task handle sending the request.
