When IP route cache had been removed in linux-3.6, we broke assumption
that dst entries were all freed after rcu grace period. DST_NOCACHE
dst were supposed to be freed from dst_release(). But it appears
we want to keep such dst around, either in UDP sockets or tunnels.
In sk_dst_get() we need to make sure dst refcount is not 0
before incrementing it, or else we might end up freeing a dst
twice.
DST_NOCACHE set on a dst does not mean this dst can not be attached
to a socket or a tunnel.
Then, before actual freeing, we need to observe a rcu grace period
to make sure all other cpus can catch the fact the dst is no longer
usable.

Commit 3f85944fe2 ("net: Add sysfs file

have multiple ports on the same PCI function, and used dev_id to
identify those ports. That use was removed by commit
8c367fcbe6 ("cxgb4: Do not set
net_device::dev_id to VI index"), since dev_id should be used only when
devices share the same MAC address.
Using dev_port for cxgb4 allows different ports on the same PCI function
to be identified.

The original code uses netdev->real_num_tx_queues to bookkeep number of
queues and invokes netif_set_real_num_tx_queues to set the number of
queues. However, netif_set_real_num_tx_queues doesn't allow
real_num_tx_queues to be smaller than 1, which means setting the number
to 0 will not work and real_num_tx_queues is untouched.
This is bogus when xenvif_free is invoked before any number of queues is
allocated. That function needs to iterate through all queues to free
resources. Using the wrong number of queues results in NULL pointer
dereference.
So we bookkeep the number of queues in xen-netback to solve this
problem. This fixes a regression introduced by multiqueue patchset in
3.16-rc1.
There's another bug in original code that the real number of RX queues
is never set. In current Xen multiqueue design, the number of TX queues
and RX queues are in fact the same. We need to set the numbers of TX and
RX queues to the same value.
Also remove xenvif_select_queue and leave queue selection to core
driver, as suggested by David Miller.

HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the
default high-pass filter in some "safer" range, which results in the
very soft tone from the built-in speakers in contrast to Windows.
Also, the mute LED control is missing, since 92HD95 codec still has no
HP-specific fixups for GPIO setups.
This patch adds these missing features: the HPF is adjusted by the
vendor-specific verb, and the LED is set up from a DMI string (but
with the default polarity = 0 assumption due to the incomplete BIOS on
the given machine).

kvm_arch_vcpu_free() is called in 2 code paths:
1) kvm_vm_ioctl()
kvm_vm_ioctl_create_vcpu()
kvm_arch_vcpu_destroy()
kvm_arch_vcpu_free()
2) kvm_put_kvm()
kvm_destroy_vm()
kvm_arch_destroy_vm()
kvm_mips_free_vcpus()
kvm_arch_vcpu_free()
Neither of the paths handles VCPU free. We need to do it in
kvm_arch_vcpu_free() corresponding to the memory allocation in
kvm_arch_vcpu_create().

race condition that happens between enabling/disabling syscall tracepoints
and new process creations (the check to go into the ptrace path for a process
can be set when it shouldn't, or not set when it should). Not a major bug
but one that should be fixed and even applied to stable.
The other two patches are cleanup/fixes that are not that critical, but
for an -rc1 release would be nice to have. They both deal with syscall
tracepoints.
It also includes a patch to introduce a new macro for the TRACE_EVENT()
format called __field_struct(). Originally, __field() was used to record
any variable into a trace event, but with the addition of setting the
"is signed" attribute, the check causes anything but a primitive variable
to fail to compile. That is, structs and unions can't be used as they
once were. When the "is signed" check was introduce there were only
primitive variables being recorded. But that will change soon and it
was reported that __field() causes build failures.
To solve the __field() issue, __field_struct() is introduced to allow
trace_events to be able to record complex types too.

AT91 symbols AT91SAM9263, AT91SAM9RL, and AT91SAM9G45 do not exist and this
patch changes them to their correct ARCH_* version.
These symbols are chosen instead of the SOC_* ones because this driver is not
converted to DT.
Anyway, the ATMEL_PWM symbol and the associated driver will be removed soon,
during the move to the PWM sub-system.

Even though the virtio-scsi spec guarantees that all requests related
to the TMF will have been completed by the time the TMF itself completes,
the request queue's callback might not have run yet. This causes requests
to be completed more than once, and as a result triggers a variety of
BUGs or oopses.

If a CRQ reset is triggered for some reason while in the middle

call the done function for the initialization MAD commands as
this will only result in two threads attempting initialization
at the same time, resulting in failures.

Its due to the fact that we call a potentially sleeping function from the bnx2fc
rcv path with preemption disabled (via the get_cpu call embedded in the per-cpu
variable stats lookup in bnx2fc_l2_rcv_thread.
Easy enough fix, we can just move the stats collection later in the function
where we are sure we won't preempt or sleep. This also allows us to not have to
enable pre-emption when doing a per-cpu lookup, since we're certain not to get
rescheduled.

In case of of error, the bnx2fc_cmd_mgr_alloc() function will call
the bnx2fc_cmd_mgr_free() to perform the cleanup.
The problem is that in one case the latter may try to scan
some not-yet initialized lists, resulting in a kernel panic.
This patch prevents this from happening by freeing the lists
before calling bnx2fc_cmd_mgr_free().
