Backmerge to help out Intel guys.
Pull networking fixes from David Miller:
"I know this is a bit more than you want to see, and I've told the
wireless folks under no uncertain terms that they must severely scale
back the extent of the fixes they are submitting this late in the
game.
Anyways:
1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which
is the correct implementation, like it should. Instead it does
something like a NAPI poll operation. This leads to crashes.
From Neil Horman and Arnd Bergmann.
2) Segmentation of SKBs requires proper socket orphaning of the
fragments, otherwise we might access stale state released by the
release callbacks.
This is a 5 patch fix, but the initial patches are giving
variables and such significantly clearer names such that the
actual fix itself at the end looks trivial.
From Michael S. Tsirkin.
3) TCP control block release can deadlock if invoked from a timer on
an already "owned" socket. Fix from Eric Dumazet.
4) In the bridge multicast code, we must validate that the
destination address of general queries is the link local all-nodes
multicast address. From Linus Lüssing.
5) The x86 BPF JIT support for negative offsets puts the parameter
for the helper function call in the wrong register. Fix from
Alexei Starovoitov.
6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the
r8169 driver is incorrect. Fix from Hayes Wang.
7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see
if a packet is a GSO frame, but that's not the correct test. It
should use skb_is_gso(skb) instead. Fix from Wei Liu.
8) Negative msg->msg_namelen values should generate an error, from
Matthew Leach.
9) at86rf230 can deadlock because it takes the same lock from it's
ISR and it's hard_start_xmit method, without disabling interrupts
in the latter. Fix from Alexander Aring.
10) The FEC driver's restart doesn't perform operations in the correct
order, so promiscuous settings can get lost. Fix from Stefan
Wahren.
11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann.
12) Reference count and memory leak fixes in TIPC from Ying Xue and
Erik Hugne.
13) Forced eviction in inet_frag_evictor() must strictly make sure all
frags are deleted, otherwise module unload (f.e. 6lowpan) can
crash. Fix from Florian Westphal.
14) Remove assumptions in AF_UNIX's use of csum_partial() (which it
uses as a hash function), which breaks on PowerPC. From Anton
Blanchard.
The main gist of the issue is that csum_partial() is defined only
as a value that, once folded (f.e. via csum_fold()) produces a
correct 16-bit checksum. It is legitimate, therefore, for
csum_partial() to produce two different 32-bit values over the
same data if their respective alignments are different.
15) Fix endiannes bug in MAC address handling of ibmveth driver, also
from Anton Blanchard.
16) Error checks for ipv6 exthdrs offload registration are reversed,
from Anton Nayshtut.
17) Externally triggered ipv6 addrconf routes should count against the
garbage collection threshold. Fix from Sabrina Dubroca.
18) The PCI shutdown handler added to the bnx2 driver can wedge the
chip if it was not brought up earlier already, which in particular
causes the firmware to shut down the PHY. Fix from Michael Chan.
19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as
currently coded it can and does trigger in legitimate situations.
From Eric Dumazet.
20) BNA driver fails to build on ARM because of a too large udelay()
call, fix from Ben Hutchings.
21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix
from Eric Dumazet.
22) The vlan passthrough ops added in the previous release causes a
regression in source MAC address setting of outgoing headers in
some circumstances. Fix from Peter Boström"

For giant hilarity the DocBook reference overview is only generated
when in a level 2 section, not in a level 3 section. So we need to
move this up a bit as a side-by-side section to the main PRIME
documentation.
Whatever.
To have a complete set of references add the missing kerneldoc for all
functions exported to modules with the exception of the file private
init/destroy functions - drivers have no business calling those, so
let's just drop the EXPORT_SYMBOL instead.
Also reflow the function parameters to align correctly and break at 80
chars - my OCD couldn't stand them while writing the kerneldoc ;-)

PRIME fds aren't actually GEM fds but are (like the modeset API)
independent of the underlying buffer manager, as long as that one uses
uint32_t as handles. So move that entire section out of the GEM
section and reword it a bit to clarify which parts of PRIME are
generic, and which are the mandatory pieces for GEM drivers to
correctly implement the GEM lifetime rules. The rewording mostly
consists of not mixing up GEM, PRIME and DRM.
I've considered adding some blurbs to the GEM object lifetime section
about interactions with dma-bufs, but then dropped that. As long as
drivers use the right helpers they should have this all implemented
correctly and hence can be regarded as an implementation detail of the
PRIME/GEM helpers. So no need to confuse driver writers with those
tricky interactions.

- This is _not_ a generic interface to create gem objects, but just an
interface to make early boot services (like boot splash) with a
generic KMS userspace driver possible. Hence it's better to move
the documentation for this from the GEM section to the KMS section,
next to the creation of framebuffer objects.
- Make it really clear that the returned handle isn't necessarily a
GEM object (it can also be e.g. a TTM handle when running on top of
vmwgfx).
- Add a paragraph to make it clear that this is just for unaccelarated
userspace - gpu drivers need to have their own buffer object
creation ioctl which is hardware specific.
v2: Clarify that the documentation doesn't just apply to GEM-based
drivers only but is now generally valid, as suggested by David.

clarification, both suggested by Laurent.

A collection of fixes for ARM platforms. A little large due to us missing to
do one last week, but there's nothing in particular here that is in itself
large and scary.
Mostly a handful of smaller fixes all over the place. The majority is made
up of fixes for OMAP, but there are a few for others as well. In particular,
there was a decision to rename a binding for the Broadcom pinctrl block that
we need to go in before the final release since we then treat it as ABI.

"A collection of fixes for ARM platforms. A little large due to us
missing to do one last week, but there's nothing in particular here
that is in itself large and scary.
Mostly a handful of smaller fixes all over the place. The majority is
made up of fixes for OMAP, but there are a few for others as well. In
particular, there was a decision to rename a binding for the Broadcom
pinctrl block that we need to go in before the final release since we
then treat it as ABI"

dm-snapshot metadata corruption fix for bug introduced in 3.14-rc1, an
important refcount < 0 fix for the DM persistent data library's space
map metadata interface which fixes corruption reported by a few dm-thinp
users, and last but not least: more extensive fixes than ideal for
dm-thinp's data resize capability (which has had growing pain much like
we've seen from -ENOSPC handling of filesystems that mature). The end
result is dm-thinp now handles metadata operation failure and no data
space error conditions much better than before.

The original documentation was very unclear.
The code fix is presumably related to the formerly unclear
documentation: SOCK_TIMESTAMPING_RX_SOFTWARE has no effect on
__sock_recv_timestamp's behavior, so calling __sock_recv_ts_and_drops
from sock_recv_ts_and_drops if only SOCK_TIMESTAMPING_RX_SOFTWARE is
set is pointless. This should have no user-observable effect.

If a thin metadata operation fails the current transaction will abort,
whereby causing potential for IO layers up the stack (e.g. filesystems)
to have data loss. As such, set THIN_METADATA_NEEDS_CHECK_FLAG in the
thin metadata's superblock which:
1) requires the user verify the thin metadata is consistent (e.g. use
thin_check, etc)
2) suggests the user verify the thin data is consistent (e.g. use fsck)
The only way to clear the superblock's THIN_METADATA_NEEDS_CHECK_FLAG is
to run thin_repair.
On metadata operation failure: abort current metadata transaction, set
pool in read-only mode, and now set the needs_check flag.
As part of this change, constraints are introduced or relaxed:
* don't allow a pool to transition to write mode if needs_check is set
* don't allow data or metadata space to be resized if needs_check is set
* if a thin pool's metadata space is exhausted: the kernel will now
force the user to take the pool offline for repair before the kernel
will allow the metadata space to be extended.
Also, update Documentation to include information about when the thin
provisioning target commits metadata, how it handles metadata failures
and running out of space.

In commit e2d265d3b5 (canfd: add support for CAN FD in CAN_RAW sockets)
CAN FD frames with a payload length up to 8 byte are passed to legacy
sockets where the CAN FD support was not enabled by the application.
After some discussions with developers at a fair this well meant feature
leads to confusion as no clean switch for CAN / CAN FD is provided to the
application programmer. Additionally a compatibility like this for legacy
CAN_RAW sockets requires some compatibility handling for the sending, e.g.
make CAN2.0 frames a CAN FD frame with BRS at transmission time (?!?).
This will become a mess when people start to develop applications with
real CAN FD hardware. This patch reverts the bad compatibility code
together with the documentation describing the removed feature.

Updates from Jean-Fracois for the TDA998x driver, which are on top of
the fixes you have previously pulled, except these changes aren't
intended for -rc, but the next merge window.
Several of these are issues of correctness - passing more correct HDMI
info packets, not reading registers in older chips documented as write
only (despite appearing to be read/write in later chips). Others are
code cleanups (using definitions rather than constants where we have
them already in the kernel).
Additional functionality is also added by way of optional support for
the IRQ from the TDA998x, which allows us to avoid busy-waiting for
the EDID reads.
