When a VF originating from a given PF is flr-ed, that PF gets an interrupt
from the chip management and takes a part in the flr process.
This patch fixes several corner cases in which the driver performs its part
of the flr flow out-of-order, causing the FW to assert due to badly timed
messages received from the driver.

In the cluster evironment, cluster write has poor performance because
userspace_flush() has to contact a userspace program (cmirrord) for
clear/mark/flush requests. But both mark and flush requests require
cmirrord to communicate the message to all the cluster nodes for each
flush call. This behaviour is really slow.
To address this we now merge mark and flush requests together to reduce
the kernel-userspace-kernel time. We allow a new directive,
"integrated_flush" that can be used to instruct the kernel log code to
combine flush and mark requests when directed by userspace. If not
directed by userspace (due to an older version of the userspace code
perhaps), the kernel will function as it did previously - preserving
backwards compatibility. Additionally, flush requests are performed
lazily when only clear requests exist.

This patch addresses a bug in bio_integrity_verify() code that has
been causing DIF READ verify operations to be silently skipped.
The issue is that bio->bi_idx will have been incremented within
bio_advance() code in the normal blk_update_request() ->
req_bio_endio() completion path, and bio_integrity_verify() is
using bio_for_each_segment() which starts the bio segment walk
at the current bio->bi_idx.
So instead use bio_for_each_segment_all() to always start the bio
segment walk from zero, regardless of the current bio->bi_idx
value after bio_advance() has been called.

The mtip32xx driver makes a high order dma memory allocation to store a
command index table, some dedicated buffers, and a command header & SGL
blob. This allocation can fail with a surprise insert under low &
fragmented memory conditions.
This patch breaks these regions up into separate low order allocations
and increases the maximum number of segments a single command SGL can
have. We wanted to allow at least 256 segments for 1 MB direct IO.
Since the command header occupies the first 0x80 bytes of the SGL blob,
that meant we needed two 4k pages to contain the header and SGL. The
two pages allow up to 504 SGL segments.

Michal Sekletar added in commit ea02f9411d ("net: introduce
SO_BPF_EXTENSIONS") a facility where user space can enquire
the BPF ancillary instruction set, which is imho a step into
the right direction for letting user space high-level to BPF
optimizers make an informed decision for possibly using these
extensions.
The original rationale was to return through a getsockopt(2)
a bitfield of which instructions are supported and which
are not, as of right now, we just return 0 to indicate a
base support for SKF_AD_PROTOCOL up to SKF_AD_PAY_OFFSET.
Limitations of this approach are that this API which we need
to maintain for a long time can only support a maximum of 32
extensions, and needs to be additionally maintained/updated
when each new extension that comes in.
I thought about this a bit more and what we can do here to
overcome this is to just return SKF_AD_MAX. Since we never
remove any extension since we cannot break user space and
always linearly increase SKF_AD_MAX on each newly added
extension, user space can make a decision on what extensions
are supported in the whole set of extensions and which aren't,
by just checking which of them from the whole set have an
offset < SKF_AD_MAX of the underlying kernel.
Since SKF_AD_MAX must be updated each time we add new ones,
we don't need to introduce an additional enum and got
maintenance for free. At some point in time when
SO_BPF_EXTENSIONS becomes ubiquitous for most kernels, then
an application can simply make use of this and easily be run
on newer or older underlying kernels without needing to be
recompiled, of course. Since that is for 3.14, it's not too
late to do this change.

In sctp.h we can find some macro locking wrappers. As Neil point out that:
"Its because in the origional implementation of the sctp protocol, there was a
user space test harness which built the kernel module for userspace execution to
cary our some unit testing on the code. It did so by redefining some of those
locking macros to user space friendly code. IIRC we haven't use those unit
tests in years, and so should be removing them, not adding them to other
locations."

net: Add GRO support for UDP encapsulating protocols
This series adds GRO handlers for protocols that do UDP encapsulation, with the
intent of being able to coalesce packets which encapsulate packets belonging to
the same TCP session.
For GRO purposes, the destination UDP port takes the role of the ether type
field in the ethernet header or the next protocol in the IP header.
The UDP GRO handler will only attempt to coalesce packets whose destination
port is registered to have gro handler.
The patches done against net-next 75e4364f67 "net: stmmac: fix NULL pointer
dereference in stmmac_get_tx_hwtstamp"
Or.
v4 --> v5 changes:
- followed Eric's directives to avoid using atomic get/put ops on the
udp gro receive and complete callbacks and instead keep the rcu_read_lock
when calling the next handler on the chain.
v3 --> v4 changes:
- applied feedback from Tom on some micro-optimizations that save
branches and goto directives in the udp gro logic
- applied feedback from Eric on correct RCU programming for the
add/remove flow of the upper protocols udp gro handlers
v2 --> v3 changes:
- moved to use linked list to store the udp gro handlers, this solves the
problem of consuming 512KB of memory for the handlers.
- use a mark on the skb GRO CB data to disallow running the udp gro_receive twice
on a packet, this solves the problem of udp encapsulated packets whose inner VM
packet is udp and happen to carry a port which has registered offloads - and flush it.
- invoke the udp offload protocol registration and de-registration from the vxlan driver
in a sleepable context

Merge tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw
Pull GFS2 updates from Steven Whitehouse:
"The main topics this time are allocation, in the form of Bob's
improvements when searching resource groups and several updates to
quotas which should increase scalability. The quota changes follow on
from those in the last merge window, and there will likely be further
work to come in this area in due course.
There are also a few patches which help to improve efficiency of
adding entries into directories, and clean up some of that code.
One on-disk change is included this time, which is to write some
additional information which should be useful to fsck and also
potentially for debugging.
Other than that, its just a few small random bug fixes and clean ups"

This change adds a parameter for the Synopsys 10/100/1000
stmmac Ethernet driver to configure the maximum frame
size supported by the EMAC driver. Synopsys allows the FIFO
sizes to be configured when the cores are built for a particular
device, but do not provide a way for the driver to read
information from the device about the maximum MTU size
supported as limited by the device's FIFO size.

Smatch complains because we are using an untrusted index into the
rxrpc_acks[] array. It's just a read and it's only in the debug code,
but it's simple enough to add a check and fix it.

Replace deprecated 'vconfig' tool with 'ip' from 'iproute2'. Add
some beautifications like replacing 'ethernet' with 'Ethernet' and
removing unneeded spaces.

Some ipv6 protocols cannot handle ipv4 addresses, so we must not allow
connecting and binding to them. sendmsg logic does already check msg->name
for this but must trust already connected sockets which could be set up
for connection to ipv4 address family.
Per-socket flag ipv6only is of no use here, as it is under users control
by setsockopt.
