Dummy packets are currently only sent on the system_hlid link. The
system_hlid link should never be filtered for PS (as it is not
a STA link). Even so, for correctness, don't indicate dummy packets up.
The skb does not belong to mac80211 and as such does not contain a
correct skb->cb.

For now, cfg80211 only support match sets with SSIDs, but in the
future more parameters will be added. This patch ignores eventual
matches that do not contain SSIDs in preparation for the future. This
change also affects the case where broadcast SSIDs are used. Matching
a broadcast SSID will match everything, so they can be ignored.

The latest firmware supports up to 16 SSIDs in the scheduled scan
lists. Increase the number we report to cfg80211 and increase the
min/max dwell time to 30 and 60 TUs respectively, because otherwise we
don't have the time to send the probes for all SSIDs.

Implement support for filtering in scheduled scans.
With this commit we now use the match sets passed by cfg80211 to
filter on SSIDs. Due to the nature of the wl12xx firmware API, we
don't allow SSIDs to be sent in the probe requests if they are not
going to match any of the filters.

The firmware only asks for one dummy packet at a time, but sometimes we
are unable to provide it before a FW timer expires. When this happens,
the FW will re-request the dummy packet. If a packet is still queued in
the driver queues, do nothing in this case.
This prevents spurious dummy packets from clogging up the VO AC.

In __blk_complete_request, we check both QUEUE_FLAG_SAME_COMP and req->cpu
to decide whether we should use req->cpu. Actually the user can also
select the complete cpu by either setting BIO_CPU_AFFINE or by calling
bio_set_completion_cpu. Current solution makes these 2 ways don't work

In pcie_find_smpss(), we have the following statement:
if (dev->is_hotplug_bridge && (!list_is_singular(&dev->bus->devices) ||
dev->bus->self->pcie_type != PCI_EXP_TYPE_ROOT_PORT))
The problem is that at least on my machine, this gets called for the
root complex (virtual P2P bridge), and dev->bus->self is NULL since
the parent bus for this is not itself anchor to a PCI device.
This adds the necessary NULL check.

Do not allow multiple mounts on same mountpoint when using -o noac
When you normally attempt to mount a share twice on the same mountpoint,
a check in do_add_mount causes it to return an error
# mount localhost:/nfsv3 /mnt
# mount localhost:/nfsv3 /mnt
mount.nfs: /mnt is already mounted or busy
However when using the option 'noac', the user is able to mount the same
share on the same mountpoint multiple times. This happens because a
share mounted with the noac option is automatically assigned the 'sync'
flag MS_SYNCHRONOUS in nfs_initialise_sb(). This flag is set after the
check for already existing superblocks is done in sget(). The check for
the mount flags in nfs_compare_mount_options() does not take into
account the 'sync' flag applied later on in the code path. This means
that when using 'noac', a new superblock structure is assigned for every
new mount of the same share and multiple shares on the same mountpoint
are allowed.
ie.
# mount -onoac localhost:/nfsv3 /mnt
can be run multiple times.
The patch checks for noac and assigns the sync flag before sget() is
called to obtain an already existing superblock structure.

Introduce filtering for scheduled scans to reduce the number of
unnecessary results (which cause useless wake-ups).
Add a new nested attribute where sets of parameters to be matched can
be passed when starting a scheduled scan. Only scan results that
match any of the sets will be returned.
At this point, the set consists of a single parameter, an SSID. This
can be easily extended in the future to support more complex matches.
