If a dt mdio entry has been added least assume that we wont
search for phys attached. The DT and of_mdiobus_register already do
this. This stops DSA phys being found and phys created for them, as
this is handled by the DSA driver.

Currently output of MPLS packets on tunnel vports is not allowed by Open
vSwitch. This is because historically encapsulation was done in such a way
that the inner_protocol field of the skb needed to hold the inner protocol
for both MPLS and tunnel encapsulation in order for GSO segmentation to be
performed correctly.
Since b2acd1dc39 ("openvswitch: Use regular GRE net_device instead of
vport") Open vSwitch makes use of lwt to output to tunnel netdevs which
perform encapsulation. As no drivers expose support for MPLS offloads this
means that GSO packets are segmented in software by validate_xmit_skb(),
which is called from __dev_queue_xmit(), before tunnel encapsulation occurs.
This means that the inner protocol of MPLS is no longer needed by the time
encapsulation occurs and the contention on the inner_protocol field of the
skb no longer occurs.
Thus it is now safe to output MPLS to tunnel vports.

Running the following command:
busybox cat /sys/kernel/debug/tracing/trace_pipe > /dev/null
with any tracing enabled pretty very quickly leads to various NULL
pointer dereferences and VM BUG_ON()s, such as these:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000020

[<ffffffff8192cd1e>] tracesys_phase2+0x84/0x89
(busybox's cat uses sendfile(2), unlike the coreutils version)
This is because tracing_splice_read_pipe() can call splice_to_pipe()
with spd->nr_pages == 0. spd_pages underflows in splice_to_pipe() and
we fill the page pointers and the other fields of the pipe_buffers with
garbage.
All other callers of splice_to_pipe() avoid calling it when nr_pages ==
0, and we could make tracing_splice_read_pipe() do that too, but it
seems reasonable to have splice_to_page() handle this condition
gracefully.

The uas driver can never queue more then MAX_CMNDS (- 1) tags and tags
are shared between luns, so there is no need to claim that we can_queue
some random large number.
Not claiming that we can_queue 65536 commands, fixes the uas driver
failing to initialize while allocating the tag map with a "Page allocation
failure (order 7)" error on systems which have been running for a while
and thus have fragmented memory.

Core changes:
- The gpio_chip is now a *real device*. Until now the gpio chips
were just piggybacking the parent device or (gasp) floating in
space outside of the device model. We now finally make GPIO chips
devices. The gpio_chip will create a gpio_device which contains
a struct device, and this gpio_device struct is kept private.
Anything that needs to be kept private from the rest of the kernel
will gradually be moved over to the gpio_device.
- As a result of making the gpio_device a real device, we have added
resource management, so devm_gpiochip_add_data() will cut down on
overhead and reduce code lines. A huge slew of patches convert
almost all drivers in the subsystem to use this.
- Building on making the GPIO a real device, we add the first step
of a new userspace ABI: the GPIO character device. We take small
steps here, so we first add a pure *information* ABI and the tool
"lsgpio" that will list all GPIO devices on the system and all
lines on these devices. We can now discover GPIOs properly from
userspace. We still have not come up with a way to actually *use*
GPIOs from userspace.
- To encourage people to use the character device for the future,
we have it always-enabled when using GPIO. The old sysfs ABI is
still opt-in (and can be used in parallel), but is marked as
deprecated. We will keep it around for the foreseeable future,
but it will not be extended to cover ever more use cases.
Cleanup:
- Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
includes. This dates back to when GPIO was an opt-in feature and
no shared library even existed: just a header file with proper
prototypes was provided and all semantics were up to the arch to
implement. These patches make the GPIO chip even more a proper
device and cleans out leftovers of the old in-kernel API here
and there. Still some cruft is left but it's very little now.
- There is still some clamping of return values for .get() going
on, but we now return sane values in the vast majority of drivers
and the errorpath is sanitized. Some patches for powerpc, blackfin
and unicore still drop in.
- We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
implementations to use gpiochip_add_data() and cut down on code
lines.
- MPC8xxx is converted to use the generic GPIO helpers.
- ATH79 is converted to use the generic GPIO helpers.
New drivers:
- WinSystems WS16C48
- Acces 104-DIO-48E
- F81866 (a F7188x variant)
- Qoric (a MPC8xxx variant)
- TS-4800
- SPI serializers (pisosr): simple 74xx shift registers connected
to SPI to obtain a dirt-cheap output-only GPIO expander.

actual x86 conversion to deferred to 4.7 because of the merge

- Support for the User Access Override feature of ARMv8.2: this allows

Now SYN_RECV request sockets are installed in ehash table, an ICMP
handler can find a request socket while another cpu handles an incoming
packet transforming this SYN_RECV request socket into an ESTABLISHED
socket.
We need to remove the now obsolete WARN_ON(req->sk), since req->sk
is set when a new child is created and added into listener accept queue.
If this race happens, the ICMP will do nothing special.

Implement basic character sets for the '%[' conversion specifier.
The '%[' conversion specifier matches a nonempty sequence of characters
from the specified set of accepted (or with '^', rejected) characters
between the brackets. The substring matched is to be made up of
characters in (or not in) the set. This is useful for matching
substrings that are delimited by something other than spaces.
This implementation differs from its glibc counterpart in the following ways:
(1) No support for character ranges (e.g., 'a-z' or '0-9')
(2) The hyphen '-' is not a special character
(3) The closing bracket ']' cannot be matched
(4) No support (yet) for discarding matching input ('%*[')
The bitmap code is largely based upon sample code which was provided by
Rasmus.
The motivation for adding character set support to sscanf originally
stemmed from the kernel livepatching project. An ongoing patchset
utilizes new livepatch Elf symbol and section names to store important
metadata livepatch needs to properly apply its patches. Such metadata
is stored in these section and symbol names as substrings delimited by
periods '.' and commas ','. For example, a livepatch symbol name might
look like this:
.klp.sym.vmlinux.printk,0
However, sscanf currently can only extract "substrings" delimited by
whitespace using the "%s" specifier. Thus for the above symbol name,
one cannot not use sscanf() to extract substrings "vmlinux" or
"printk", for example. A number of discussions on the livepatch
mailing list dealing with string parsing code for extracting these '.'
and ',' delimited substrings eventually led to the conclusion that such
code would be completely unnecessary if the kernel sscanf() supported
character sets. Thus only a single sscanf() call would be necessary to
extract these substrings. In addition, such an addition to sscanf()
could benefit other areas of the kernel that might have a similar need
in the future.

The traceoff_on_warning option doesn't have any effect on s390, powerpc,
arm64, parisc, and sh because there are two different types of WARN
implementations:
1) The above mentioned architectures treat WARN() as a special case of a
BUG() exception. They handle warnings in report_bug() in lib/bug.c.
2) All other architectures just call warn_slowpath_*() directly. Their
warnings are handled in warn_slowpath_common() in kernel/panic.c.
Support traceoff_on_warning on all architectures and prevent any future
divergence by using a single common function to emit the warning.
Also remove the '()' from '%pS()', because the parentheses look funky:

kstrtobool(), update the callers to not pass single-character pointers,
and switch to using the new kstrtobool_from_user() helper where
possible.

Sometimes gcc mysteriously doesn't inline
very small functions we expect to be inlined. See
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66122
With this .config:
http://busybox.net/~vda/kernel_config_OPTIMIZE_INLINING_and_Os,
atomic_long_inc(), atomic_long_dec() and atomic_long_add()
functions get deinlined about 40 times. Examples of disassembly:
<atomic_long_inc> (21 copies, 147 calls):
55 push %rbp
48 89 e5 mov %rsp,%rbp
f0 48 ff 07 lock incq (%rdi)
5d pop %rbp
c3 retq
<atomic_long_dec> (4 copies, 14 calls) is similar to inc.
<atomic_long_add> (11 copies, 41 calls):
55 push %rbp
48 89 e5 mov %rsp,%rbp
f0 48 01 3e lock add %rdi,(%rsi)
