This patch adds phy reset callback support for stmmac driver via device
trees. It adds three new properties to gmac device tree bindings to
define the reset signal via gpio.
With this patch users can conveniently pass reset gpio number with pre,
pulse and post delay in micro secs via DTs.

In some DT use-cases platform data might be already allocated and passed

Commit 55257d72bd (virtio-net: fill only rx queues
which are being used) tries to refill on demand when changing the number of
channels by call try_refill_recv() directly, this may race:
- the refill work who may do the refill in the same time
- the try_refill_recv() called in bh since napi was not disabled
Which may led guest complain during setting channels:
virtio_net virtio0: input.1:id 0 is not a head!
Solve this issue by scheduling a refill work which can guarantee the
serialization of refill.

Rework probe/remove routines to prevent rionet driver from monopolizing
target RapidIO devices. Fix conflict with modular RapidIO switch drivers.
Using one of RapidIO messaging channels rionet driver provides a service
layer common to all endpoint devices in a system's RapidIO network. These
devices may also require their own specific device driver which will be
blocked from attaching to the target device by rionet (or block rionet if
loaded earlier). To avoid conflict with device-specific drivers, the
rionet driver is reworked to be registered as a subsystem interface on the
RapidIO bus.
The reworked rio_remove_dev() and rionet_exit() routines also include
handling of individual rionet peer device removal which was not supported
before.

Pull workqueue changes from Tejun Heo:
"Surprisingly, Lai and I didn't break too many things implementing
custom pools and stuff last time around and there aren't any follow-up
changes necessary at this point.
The only change in this pull request is Viresh's patches to make some
per-cpu workqueues to behave as unbound workqueues dependent on a boot
param whose default can be configured via a config option. This leads
to higher processing overhead / lower bandwidth as more work items are
bounced across CPUs; however, it can lead to noticeable powersave in
certain configurations - ~10% w/ idlish constant workload on a
big.LITTLE configuration according to Viresh.
This is because per-cpu workqueues interfere with how the scheduler
perceives whether or not each CPU is idle by forcing pinned tasks on
them, which makes the scheduler's power-aware scheduling decisions
less effective.
Its effectiveness is likely less pronounced on homogenous
configurations and this type of optimization can probably be made
automatic; however, the changes are pretty minimal and the affected
workqueues are clearly marked, so it's an easy gain for some
configurations for the time being with pretty unintrusive changes."

naming this interface as both master and slave, so it is supportable

identical.

====================
Yet one more pull request for wireless updates intended for 3.11...
For the mac80211 bits, Johannes says:
"Here we have a few memory leak fixes related to BSS struct handling
mostly from Ben, including a fix for a more theoretical problem
(associating while a BSS struct times out) from myself, a compilation
warning fix from Arend, mesh fixes from Thomas, tracking the beacon
bitrate (Alex), a bandwidth change event fix (Ilan) and some initial
work for 5/10 MHz channels from Simon."
Regarding the iwlwifi bits, Johannes says:
"Emmanuel removed some unneeded/unsupported module parameters and adds a
Bluetooth 1x1 lookup-table for some upcoming products. From Alex I have
an older patch to add low-power receive support, this depended on a
mac80211 commit that only just came in with the merge from wireless-next
I did. Ilan made beacon timings better, and Eytan added some debug
statements for thermal throttling. I have a few cleanups, a fix for a
long-standing but rare warning, and, arguably the most important patch
here, the firmware API version bump for the 7260/3160 devices."
Also included is a Bluetooth pull -- Gustavo says:
"Here goes a set of patches to 3.11. The biggest work here is from Andre Guedes
on the move of the Discovery to use the new request framework. Other than that
Johan provided a bunch of fixes to the L2CAP code. The rest are just small
fixes and clean ups."
On top of all that, there are a variety of updates and fixes to
brcmfmac, rt2x00, wil6210, ath9k, ath10k, and a few others here and
there. This also includes a pull of the wireless tree, in order to
prevent some merge conflicts.

Thus, we should simply remove the test against INT_MAX. Next to that
we also need to explicitly cast the sizeof() case as the comparison
is type promoted to unsigned long so negative values are then
valid instead of invalid. While at it, this also adds a comment about

In struct bonding there's a member called dev_addr_from_first which is
used to denote when the bond dev should clone the first slave's MAC
address but since we have netdev's addr_assign_type variable that is not
necessary. We clone the first slave's MAC each time we have a random MAC
set to the bond device. This has the nice side-effect of also fixing an
inconsistency - when the MAC address of the bond dev is set after its
creation, but prior to having slaves, it's not kept and the first slave's
MAC is cloned. The only way to keep the MAC was to create the bond device
with the MAC address set (e.g. through ip link). In all cases if the
bond device is left without any slaves - its MAC gets reset to a random
one as before.

As reported by "kbuild test robot" there were some errors and warnings
on attempt to build kernel with "make ARCH=powerpc allmodconfig".
And this patch addresses both errors and warnings.
Below is a list of introduced changes:
1. Fix compile-time errors (misspellings in "dma_unmap_single") on PPC.
2. Use DMA address instead of "skb->data" as a pointer to data buffer.
This fixed warnings on pointer to int conversion on 64-bit systems.
3. Re-implemented initial allocation of Rx buffers in "arc_emac_open" in
the same way they're re-allocated during operation (receiving packets).
So once again DMA address could be used instead of "skb->data".
4. Explicitly use EMAC_BUFFER_SIZE for Rx buffers allocation.

When the EEH error is the result of a fenced host bridge, MMIO accesses
can be very slow (milliseconds) to timeout and return all 1's,
thus causing the driver various timeout loops to take way too long and
trigger soft-lockup warnings (in addition to taking minutes to recover).
It might be worthwhile to check if for any of these cases, ffffffff is
a valid possible value, and if not, bail early since that means the HW
is either gone or isolated. In the meantime, checking that the PCI channel
is offline would be workaround of the problem.

Currently, we fail only when all of the ips in arp_ip_target are gone.
However, in some situations we might need to fail if even one host from
arp_ip_target becomes unavailable.
All situations, obviously, rely on the idea that we need *completely*
functional network, with all interfaces/addresses working correctly.
One real world example might be:
vlans on top on bond (hybrid port). If bond and vlans have ips assigned
and we have their peers monitored via arp_ip_target - in case of switch
misconfiguration (trunk/access port), slave driver malfunction or
tagged/untagged traffic dropped on the way - we will be able to switch
to another slave.
Though any other configuration needs that if we need to have access to all
arp_ip_targets.
This patch adds this possibility by adding a new parameter -
arp_all_targets (both as a module parameter and as a sysfs knob). It can be
set to:
0 or any (the default) - which works exactly as it's working now -
the slave is up if any of the arp_ip_targets are up.
1 or all - the slave is up if all of the arp_ip_targets are up.
This parameter can be changed on the fly (via sysfs), and requires the mode
to be active-backup and arp_validate to be enabled (it obeys the
arp_validate config on which slaves to validate).
Internally it's done through:
1) Add target_last_arp_rx[BOND_MAX_ARP_TARGETS] array to slave struct. It's
an array of jiffies, meaning that slave->target_last_arp_rx[i] is the
last time we've received arp from bond->params.arp_targets[i] on this
slave.
2) If we successfully validate an arp from bond->params.arp_targets[i] in
bond_validate_arp() - update the slave->target_last_arp_rx[i] with the
current jiffies value.
3) When getting slave's last_rx via slave_last_rx(), we return the oldest
time when we've received an arp from any address in
bond->params.arp_targets[].
If the value of arp_all_targets == 0 - we still work the same way as
before.
Also, update the documentation to reflect the new parameter.
v3->v4:
Kill the forgotten rtnl_unlock(), rephrase the documentation part to be
more clear, don't fail setting arp_all_targets if arp_validate is not set -
it has no effect anyway but can be easier to set up. Also, print a warning
if the last arp_ip_target is removed while the arp_interval is on, but not
the arp_validate.
v2->v3:
Use _bh spinlock, remove useless rtnl_lock() and use jiffies for new
arp_ip_target last arp, instead of slave_last_rx(). On bond_enslave(),
use the same initialization value for target_last_arp_rx[] as is used
for the default last_arp_rx, to avoid useless interface flaps.
Also, instead of failing to remove the last arp_ip_target just print a
warning - otherwise it might break existing scripts.
v1->v2:
Correctly handle adding/removing hosts in arp_ip_target - we need to
shift/initialize all slave's target_last_arp_rx. Also, don't fail module
loading on arp_all_targets misconfiguration, just disable it, and some
minor style fixes.
