Hans de Goede 757e55c23d gspca: Fix bulk mode cameras no longer working (regression fix)
The new iso bandwidth calculation code accidentally has broken support
for bulk mode cameras. This has broken the following drivers:
finepix, jeilinj, ovfx2, ov534, ov534_9, se401, sq905, sq905c, sq930x,
stv0680, vicam.

Thix patch fixes this. Fix tested with: se401, sq905, sq905c, stv0680 & vicam
cams.

Rusty Russell f1776dade1 virtio_net: use non-reentrant workqueue.
Michael S. Tsirkin also noticed that we could run the refill work
multiple CPUs: if we kick off a refill on one CPU and then on another,
they would both manipulate the queue at the same time (they use
napi_disable to avoid racing against the receive handler itself).

Tejun points out that this is what the WQ_NON_REENTRANT flag is for,
and that there is a convenient system kthread we can use.

Rusty Russell b2baed69e6 virtio_net: set/cancel work on ndo_open/ndo_stop
Michael S. Tsirkin noticed that we could run the refill work after
ndo_close, which can re-enable napi - we don't disable it until
virtnet_remove.  This is clearly wrong, so move the workqueue control
to ndo_open and ndo_stop (aka. virtnet_open and virtnet_close).

One subtle point: virtnet_probe() could simply fail if it couldn't
allocate a receive buffer, but that's less polite in virtnet_open() so
we schedule a refill as we do in the normal receive path if we run out
of memory.

Rogerio Pimentel c3b084c24c net: fec: Adjust ENET MDIO timeouts
On extensive NFS boots on a mx6qsabrelite board it was noted that "FEC: MDIO read timeout" were occuring,
which caused failure on loading the FEC driver.

The original FEC_MII_TIMEOUT was set to 1 ms, which is too low when passed to the usecs_to_jiffies macro.

On ARM one jiffy is 10ms, so use a timeout of 30ms, which corresponds to 3 jiffies.

After running extensive NFS boots, the MDIO timeouts do not occur anymore with this change.

Joshua Kinard c0d2b8376a net: meth: Add set_rx_mode hook to fix ICMPv6 neighbor discovery
SGI IP32 (O2)'s ethernet driver (meth) lacks a set_rx_mode function, which
prevents IPv6 from working completely because any ICMPv6 neighbor
solicitation requests aren't picked up by the driver.  So the machine can
ping out and connect to other systems, but other systems will have a very
hard time connecting to the O2.

NeilBrown 961902c0f8 md/bitmap: It is OK to clear bits during recovery.
commit d0a4bb4927 introduced a
regression which is annoying but fairly harmless.

When writing to an array that is undergoing recovery (a spare
in being integrated into the array), writing to the array will
set bits in the bitmap, but they will not be cleared when the
write completes.

For bits covering areas that have not been recovered yet this is not a
problem as the recovery will clear the bits.  However bits set in
already-recovered region will stay set and never be cleared.
This doesn't risk data integrity.  The only negatives are:
 - next time there is a crash, more resyncing than necessary will
   be done.
 - the bitmap doesn't look clean, which is confusing.

While an array is recovering we don't want to update the
'events_cleared' setting in the bitmap but we do still want to clear
bits that have very recently been set - providing they were written to
the recovering device.

So split those two needs - which previously both depended on 'success'
and always clear the bit of the write went to all devices.

NeilBrown 60fc13702a md: don't give up looking for spares on first failure-to-add
Before performing a recovery we try to remove any spares that
might not be working, then add any that might have become relevant.

Currently we abort on the first spare that cannot be added.
This is a false optimisation.
It is conceivable that - depending on rules in the personality - a
subsequent spare might be accepted.
Also the loop does other things like count the available spares and
reset the 'recovery_offset' value.

If we abort early these might not happen properly.

So remove the early abort.

In particular if you have an array what is undergoing recovery and
which has extra spares, then the recovery may not restart after as
reboot as the could of 'spares' might end up as zero.

NeilBrown 30d7a48368 md/raid5: ensure correct assessment of drives during degraded reshape.
While reshaping a degraded array (as when reshaping a RAID0 by first
converting it to a degraded RAID4) we currently get confused about
which devices are in_sync.  In most cases we get it right, but in the
region that is being reshaped we need to treat non-failed devices as
in-sync when we have the data but haven't actually written it out yet.

broke hot-add to a linear array.
After that commit, metadata if not written to devices until they
have been fully integrated into the array as determined by
saved_raid_disk.  That patch arranged to clear that field after
a recovery completed.

However for linear arrays, there is no recovery - the integration is
instantaneous.  So we need to explicitly clear the saved_raid_disk
field.

Xi Wang 8a78389651 vmwgfx: fix incorrect VRAM size check in vmw_kms_fb_create()
Commit e133e737 didn't correctly fix the integer overflow issue.

-	unsigned int required_size;
+	u64 required_size;
	...
	required_size = mode_cmd->pitch * mode_cmd->height;
-	if (unlikely(required_size > dev_priv->vram_size)) {
+	if (unlikely(required_size > (u64) dev_priv->vram_size)) {

Note that both pitch and height are u32.  Their product is still u32 and
would overflow before being assigned to required_size.  A correct way is
to convert pitch and height to u64 before the multiplication.

	required_size = (u64)mode_cmd->pitch * (u64)mode_cmd->height;

This patch calls the existing vmw_kms_validate_mode_vram() for
validation.

This patch adds the PCI support (as EXPERIMENTAL)
this has been also tested on XLINX XC2V3000 FF1152AMT0221
D1215994A VIRTEX FPGA board.
To support the PCI bus the main part has been reworked
and both the platform and the PCI specific parts have
been moved into different files.

Einar Lueck 72861ae792 qeth: recovery through asynchronous delivery
If recovery is triggered in presence of pending asynchronous
deliveries of storage blocks we do a forced cleanup after
the corresponding tasklets are completely stopped and trigger
appropriate notifications for the correspondingerror state.

Ursula Braun 08e3356cc2 netiucv: allow multiple interfaces to same peer
The NETIUCV device driver allows to connect a Linux guest on z/VM to
another z/VM guest based on the z/VM communication facility IUCV.
Multiple output paths to different guests are possible, as well as
multiple input paths from different guests.
With this feature, you can configure multiple point-to-point NETIUCV
interfaces between your Linux on System z instance and another z/VM
guest.

Ursula Braun 4763b0a010 qeth: suspicious rcu_dereference_check in recovery
qeth layer3 recovery invokes its set_multicast_list function, which
invokes function __vlan_find_dev_deep requiring rcu_read_lock or
rtnl lock. This causes kernel messages:
