Previously, flows were manipulated by userspace specifying a full,
unmasked flow key. This adds significant burden onto flow
serialization/deserialization, particularly when dumping flows.
This patch adds an alternative way to refer to flows using a
variable-length "unique flow identifier" (UFID). At flow setup time,
userspace may specify a UFID for a flow, which is stored with the flow
and inserted into a separate table for lookup, in addition to the
standard flow table. Flows created using a UFID must be fetched or
deleted using the UFID.
All flow dump operations may now be made more terse with OVS_UFID_F_*
flags. For example, the OVS_UFID_F_OMIT_KEY flag allows responses to
omit the flow key from a datapath operation if the flow has a
corresponding UFID. This significantly reduces the time spent assembling
and transacting netlink messages. With all OVS_UFID_F_OMIT_* flags
enabled, the datapath only returns the UFID and statistics for each flow
during flow dump, increasing ovs-vswitchd revalidator performance by 40%
or more.

Refactor the ovs_nla_fill_match() function into separate netlink
serialization functions ovs_nla_put_{unmasked_key,mask}(). Modify
ovs_nla_put_flow() to handle attribute nesting and expose the 'is_mask'
parameter - all callers need to nest the flow, and callers have better
knowledge about whether it is serializing a mask or not.

Pull cgroup fix from Tejun Heo:
"The lifetime rules of cgroup hierarchies always have been somewhat
counter-intuitive and cgroup core tried to enforce that hierarchies
w/o userland-visible usages must die in finite amount of time so that
the controllers can be reused for other hierarchies; unfortunately,
this can't be implemented reasonably for the memory controller - the
kmemcg part doesn't have any way to forcefully drain the existing
usages, leading to an interruptible hang if a following mount attempts
to use the controller in any way.
So, it seems like we're stuck with "hierarchies live on till they die
whenever that may be" at least for now. This pretty much confines
attaching controllers to hierarchies to before the hierarchies are
actively used by making dynamic configurations post active usages
unreliable. This has never been reliable and should be fine in
practice given how cgroups are used.
After the patch, hierarchies aren't killed if it isn't already
drained. A following mount attempt of the same mount options will
reuse the existing hierarchy. Mount attempts with differing options
will fail w/ -EBUSY"

The OOM killing invocation does a lot of duplicative checks against the
task's allocation context. Rework it to take advantage of the existing
checks in the allocator slowpath.
The OOM killer is invoked when the allocator is unable to reclaim any
pages but the allocation has to keep looping. Instead of having a check
for __GFP_NORETRY hidden in oom_gfp_allowed(), just move the OOM
invocation to the true branch of should_alloc_retry(). The __GFP_FS
check from oom_gfp_allowed() can then be moved into the OOM avoidance
branch in __alloc_pages_may_oom(), along with the PF_DUMPCORE test.
__alloc_pages_may_oom() can then signal to the caller whether the OOM
killer was invoked, instead of requiring it to duplicate the order and
high_zoneidx checks to guess this when deciding whether to continue.

The device driver has plenty of command buffers available
per channel for channel command communication.
In the extremely rare case when there is no command buffer
available, return a NULL pointer and issue a warning
in the kernel log. The caller handles the case when
a NULL pointer is encountered and returns an error.
In the case the wait for command buffer is possible
(because no lock is held as in the OSN case), still wait
until a channel command buffer is available.

In the functions that are registering and unregistering MAC
addresses in the qeth-handled hardware, remove callback functions
that are unnesessary, as only the return code is analyzed.
Translate hardware response codes to semi-standard 'errno'-like
codes for readability.
Add kernel-doc description to the internal API function
qeth_send_control_data().

In commit 5a7baa7885 ("bonding: Advertize vxlan offload features when
supported"), Or Gerlitz added support conditional vxlan offload.
In this patch I also add support for all kind of tunnels,
but we allow a bonding device to not require segmentation,
as it is always better to make this segmentation at the very last stage,
if a particular slave device requires it.
Tested:
Setup a GRE tunnel,
on a physical NIC not having tx-gre-segmentation.
Results on bnx2x are even better, as we no longer have to segment
in software.

Static checkers complain that we should maybe set "ret" before we do the
"goto out;". They interpret the NULL return from br_port_get_rtnl() as
a failure and forgetting to set the error code is a common bug in this
situation.
The code is confusing but it's actually correct. We are returning zero
deliberately. Let's re-write it a bit to be more clear.

In my last commit (a3c00e4: ipv6: Remove BACKTRACK macro), the changes in
__ip6_route_redirect is incorrect. The following case is missed:
1. The for loop tries to find a valid gateway rt. If it fails to find
one, rt will be NULL.
2. When rt is NULL, it is set to the ip6_null_entry.
3. The newly added 'else if', from a3c00e4, will stop the backtrack from
happening.

A week's worth of fixes for various ARM platforms. Diff wise, the
largest fix is for OMAP to deal with how GIC now registers interrupts
(irq_domain_add_legacy() -> irq_domain_add_linear() changes).
Besides this, a few more renesas platforms needed the GIC instatiation
done for legacy boards. There's also a fix that disables coherency of
mvebu due to issues, and a few other smaller fixes.
