Pull core ARM updates from Russell King:
"This is the bulk of the core ARM updates for this merge window.
Included in here is a different way to handle the VIVT cache flushing
on context switch, which should allow scheduler folk to remove a
special case in their core code.
We have architectured timer support here, which is a set of timers
specified by the ARM architecture for future SoCs. So we should see
less variability in timer design going forward.
The last big thing here is my cleanup to the way we handle PCI across
ARM, fixing some oddities in some platforms which hadn't realised
there was a way to deal with their private data already built in to
our PCI backend.
I've also removed support for the ARMv3 architecture; it hasn't worked
properly for years so it seems pointless to keep it around."

There is no point having the NET dependency on the select target, as it
forces all users to depend on NET to tell they support BPF_JIT. Move
the config option to the bottom of the file - this could be a nice place
also for future "selectable" config symbols.
Fix up all users to drop the dependency on NET now that it is not
required to supress warnings for non-NET builds.

Pull sparc updates from David Miller:
1) Kill off support for sun4c and Cypress sun4m chips.
And as a result we were able to also kill off that ugly btfixup thing
that required multi-stage links of the final vmlinux image in the
Kbuild system. This should make the kbuild maintainers really happy.
Thanks a lot to Sam Ravnborg for his tireless efforts to get this
going.
2) Convert sparc64 to nobootmem. I suspect now with sparc32 being a lot
cleaner, it should be able to fall in line and modernize in this area
too.
3) Make sparc32 use generic clockevents, from Tkhai Kirill.
[ I fixed up the BPF rules, and tried to clean up the build rules too.
But I don't have - or want - a sparc cross-build environment, so the
BPF rule bug and the related build cleanup was all done with just a
bare "make -n" pseudo-test. - Linus ]

Pull networking changes from David Miller:
1) Get rid of the error prone NLA_PUT*() macros that used an embedded
goto.
2) Kill off the token-ring and MCA networking drivers, from Paul
Gortmaker.
3) Reduce high-order allocations made by datagram AF_UNIX sockets, from
Eric Dumazet.
4) Add PTP hardware clock support to IGB and IXGBE, from Richard
Cochran and Jacob Keller.
5) Allow users to query timestamping capabilities of a card via
ethtool, from Richard Cochran.
6) Add loadbalance mode to the teaming driver, from Jiri Pirko. Part
of this is that we can now have BPF filters not attached to sockets,
and the loadbalancing function is calculated using one.
7) Francois Romieu went through the network drivers removing gratuitous
uses of netdev->base_addr, perhaps some day we can remove it
completely but it's used for ISA probing still.
8) Add a BPF JIT for sparc. I know, who cares, right? :-)
9) Move networking sysctl registry away from using the compatability
mode interfaces in the sysctl code. From Eric W Biederman.
10) Pavel Emelyanov added a way to save and restore TCP socket state via
TCP_REPAIR, TCP_REPAIR_QUEUE, and TCP_QUEUE_SEQ socket options as
well as a way to forcefully bind a socket to a port via the
sk->sk_reuse value SK_FORCE_REUSE. There is also a
TCP_REPAIR_OPTIONS which allows to reinstante the TCP options
enabled on the connection.
11) Several enhancements from Eric Dumazet that, in particular, can
enhance splice performance on TCP sockets significantly.
a) Reset the offset of the per-socket sendmsg page when we know
we're the only use of the page in linear_to_page().
b) Add facilities such that skb->data can be backed a page rather
than SLAB kmalloc'd memory. In particular devices which were
receiving into linear RX buffers can now end up providing paged
data.
The big result is that code like splice and GRO do not have to copy
any more.
12) Allow a pure sender to more gracefully handle ACK backlogs in TCP.
What can happen at high rates is that the sender hasn't grown his
receive buffer limits at all (he's not receiving data so really
doesn't need to), but the non-data ACKs consume receive buffer
space.
sk_add_backlog() is too aggressive in dropping frames in this case,
so relax it's requirements by using the receive buffer plus the send
buffer limit as the backlog limit instead of just the former.
Also from Eric Dumazet.
13) Add ipv6 support to L2TP, from Benjamin LaHaise, James Chapman, and
Chris Elston.
14) Implement TCP early retransmit (RFC 5827), from Yuchung Cheng.
Basically, we can start fast retransmit before hiting the dupack
threshold under certain conditions.
15) New CODEL active queue management packet scheduler, from Eric
Dumazet based upon initial work by Dave Taht.
Basically, the big feature is that packets are dropped (or ECN bits
are set) based upon how long packets live in the queue, rather than
the queue length (which is what RED uses).

This teaches vfs_fstat() to use the appropriate f[get|put]_light
functions, allowing it to avoid some unnecessary locking for the common
case.
More noticeably, it also cleans up and simplifies the "getname_flags()"
function, which now relies on the architecture strncpy_from_user() doing
all the user access checks properly, instead of hacking around the fact
that on x86 it didn't use to do it right (see commit 92ae03f2ef99: "x86:
merge 32/64-bit versions of 'strncpy_from_user()' and speed it up").
* vfs-cleanups:
VFS: make vfs_fstat() use f[get|put]_light()
VFS: clean up and simplify getname_flags()
x86: make word-at-a-time strncpy_from_user clear bytes at the end

This makes cp_new_stat() a bit more readable, and avoids having to
memset() the whole structure just to fill in a couple of padding fields.
This is another result of me looking at code generation of functions
that show up high on certain kernel profiles, and just going "Oh, let's
just clean that up".
Architectures that don't supply the #define to fill just the padding
fields will still fall back to memset().
* stat-cleanups:
vfs: don't force a big memset of stat data just to clear padding fields
vfs: de-crapify "cp_new_stat()" function
