Set different dev_port value 1 for FCoE netdev than the default zero
dev_port value for PF netdev, this helps biosdevname user tool to
differentiate them correctly while both attached to the same PCI
function.

ASoC: Final updates for v3.20
A few more updates for v3.20 that have accumilated over the second half
of last week. One new (relatively simple) driver for the Maxim
max98357a and some other driver specific fixes and enhancements. I did
apply a few patches that haven't been in -next just now before sending
this, all fixes except for one simple device ID addition patch.

Stop the service task in the shutdown handler, preventing it from
accessing the admin queue after it had been closed. This fixes a panic
that could occur when the system was shut down with a lot of VFs
enabled.

ASoC: Updates for v3.20
Nothing too exciting here yet, a small optimization for DAPM from

When the module is being unloaded, don't wait for the PF to politely
handle all of our admin queue requests, as that might take forever with
a lot of VFs enabled. Instead, just stop everything and request a VF
reset.
When the original shutdown code was written, VF resets were unreliable,
so we avoided them. But with production hardware and firmware, and the
1.x PF driver, this is no longer the case.
This fixes a potential multi-minute delay on driver unload, VF disable,
or system shutdown.

During VF deallocation, we need to lock out the VF reset code. However,
we cannot depend on simply masking the interrupt, as this does not lock
out the service task, which can still call the reset routine. Instead,
leave the interrupt enabled, but add locking around the VF disable and
reset routines.
For the disable code, we wait to get the lock, as the reset code will
take a finite amount of time to run. For the reset code, we just return
if we fail to get the lock. Since we know that the VFs are being
disabled, we don't need to handle the reset.
This fixes a panic when disabling SR-IOV.

When enabling 64 VFs and loading the VF driver in the host kernel, we
can easily overrun the PF's admin receive queue. Double the size of this
queue, and increase the work limit to allow the PF to handle more
requests in a single pass through the service task.

Pull ftrace fixes from Steven Rostedt:
"During testing Sedat Dilek hit a "suspicious RCU usage" splat that
pointed out a real bug. During suspend and resume the tlb_flush
tracepoint is called when the CPU is going offline. As the CPU has
been noted as offline, RCU is ignoring that CPU, which means that it
can not use RCU protected locks. When tracepoints are activated, they
require RCU locking, and if RCU is ignoring a CPU that runs a
tracepoint, there is a chance that the tracepoint could cause
corruption.
The solution was to change the tracepoint into a
TRACE_EVENT_CONDITION() which allows us to check a condition to
determine if the tracepoint should be called or not. If the condition
is not met, the rcu protected code will not be executed. By adding
the condition "cpu_online(smp_processor_id())", this will prevent the
RCU protected code from being executed if the CPU is marked offline.
After adding this, another bug was discovered. As RCU checks rcu
callers, if a rcu call is not done, there is no check (obviously). We
found that tracepoints could be added in RCU ignored locations and not
have lockdep complain until the tracepoint is activated. This missed
places where tracepoints were added in places they should not have
been. To fix this, code was added in 3.18 that if lockdep is enabled,
any tracepoint will still call the rcu checks even if the tracepoint
is not enabled. The bug here, is that the check does not take the
CONDITION into account. As the condition may prevent tracepoints from
being activated in RCU ignored areas (as the one patch does), we get
false positives when we enable lockdep and hit a tracepoint that the
condition prevents it from being called in a RCU ignored location.
The fix for this is to add the CONDITION to the rcu checks, even if
the tracepoint is not enabled"

src_ip is a pointer to a union vxlan_addr, one member of which is a
struct sockaddr. Passing a pointer to src_ip is wrong; one should pass
the value of src_ip itself. Since %pIS formally expects something of
type struct sockaddr*, let's pass a pointer to the appropriate union
member, though this of course doesn't change the generated code.

Receive Flow Steering is a nice solution but suffers from
hash collisions when a mix of connected and unconnected traffic
is received on the host, when flow hash table is populated.
Also, clearing flow in inet_release() makes RFS not very good
for short lived flows, as many packets can follow close().
(FIN , ACK packets, ...)
This patch extends the information stored into global hash table
to not only include cpu number, but upper part of the hash value.
I use a 32bit value, and dynamically split it in two parts.
For host with less than 64 possible cpus, this gives 6 bits for the
cpu number, and 26 (32-6) bits for the upper part of the hash.
Since hash bucket selection use low order bits of the hash, we have
a full hash match, if /proc/sys/net/core/rps_sock_flow_entries is big
enough.
If the hash found in flow table does not match, we fallback to RPS (if
it is enabled for the rxqueue).
This means that a packet for an non connected flow can avoid the
IPI through a unrelated/victim CPU.
This also means we no longer have to clear the table at socket
close time, and this helps short lived flows performance.
