ARM: KVM: vgic: force EOIed LRs to the empty state

The VGIC doesn't guarantee that an EOIed LR that has been configured
to generate a maintenance interrupt will appear as empty.

While the code recovers from this situation, it is better to clean
the LR and flag it as empty so it can be quickly recycled.

ARM: KVM: vgic: take distributor lock on sync_hwstate path

Now that the maintenance interrupt handling is actually out of the
handler itself, the code becomes quite racy as we can get preempted
while we process the state.

Wrapping this code around the distributor lock ensures that we're not
preempted and relatively race-free.

ASoC: dapm: Fix handling of loops

Currently if a path loops back on itself we correctly skip over it to
avoid going into an infinite loop but this causes us to ignore the need
to power up the path as we don't count the loop for the purposes of
counting inputs and outputs. This means that internal loopbacks within a
device that have powered devices on them won't be powered up.

Fix this by treating any path that is currently in the process of being
recursed as having a single input or output so that it is counted for
the purposes of power decisions.

mac80211: always synchronize_net() during station removal

If there are keys left during station removal, then a
synchronize_net() will be done (for each key, I have a
patch to address this for 3.10), otherwise it won't be
done at all which causes issues because the station
could be used for TX while it's being removed from the
driver -- that might confuse the driver.

Fix this by always doing synchronize_net() if no key
was present any more.

cfg80211: fix potential BSS memory leak and update

In the odd case that while updating information from a beacon,
a BSS was found that is part of a hidden group, we drop the
new information. In this case, however, we leak the IE buffer
from the update, and erroneously update the entry's timestamp
so it will never time out. Fix both these issues.

clockevents: Don't allow dummy broadcast timers

Currently tick_check_broadcast_device doesn't reject clock_event_devices
with CLOCK_EVT_FEAT_DUMMY, and may select them in preference to real
hardware if they have a higher rating value. In this situation, the
dummy timer is responsible for broadcasting to itself, and the core
clockevents code may attempt to call non-existent callbacks for
programming the dummy, eventually leading to a panic.

This patch makes tick_check_broadcast_device always reject dummy timers,
preventing this problem.

amd_iommu_init: remove __init from amd_iommu_erratum_746_workaround

commit 318fe78 ("IOMMU, AMD Family15h Model10-1Fh erratum 746 Workaround")
added amd_iommu_erratum_746_workaround and it's marked as __init, which is wrong

The function iommu_init_pci() references

This is often because iommu_init_pci lacks a __init

xen/blkback: correctly respond to unknown, non-native requests

If the frontend is using a non-native protocol (e.g., a 64-bit
frontend with a 32-bit backend) and it sent an unrecognized request,
the request was not translated and the response would have the
incorrect ID.  This may cause the frontend driver to behave
incorrectly or crash.

Since the ID field in the request is always in the same place,
regardless of the request type we can get the correct ID and make a
valid response (which will report BLKIF_RSP_EOPNOTSUPP).

This bug affected 64-bit SLES 11 guests when using a 32-bit backend.
This guest does a BLKIF_OP_RESERVED_1 (BLKIF_OP_PACKET in the SLES
source) and would crash in blkif_int() as the ID in the response would
be invalid.
