Pull Documentation updates from Jon Corbet:
"A bit busier this time around.
The most interesting thing (IMO) this time around is some beginning
infrastructural work to allow documents to be written using
restructured text. Maybe someday, in a galaxy far far away, we'll be
able to eliminate the DocBook dependency and have a much better
integrated set of kernel docs. Someday.
Beyond that, there's a new document on security hardening from Kees,
the movement of some sample code over to samples/, a number of
improvements to the serial docs from Geert, and the usual collection
of corrections, typo fixes, etc"

This document attempts to codify the intent around kernel self-protection
along with discussion of both existing and desired technologies, with
attention given to the rationale behind them, and the expectations of
their usage.

As of commit ebd2c8f6d2ec4012 ("serial: kill off uart_info"), the
circular transmission buffer is part of struct uart_state instead of
struct uart_info. Make it clear this structure is pointed to from struct
uart_port.
Change 'circ' to 'circ_buf' to match the structure name while we're at
it.

Stop referring to the mutex member of the tty_port struct as
'port->mutex', as 'port' is ambiguous, and usually refers to the

A small bug with the new autoksyms support showed that there are
two kernel modules in the Documentation directory that qualify
as samples, while all other samples are in the samples/ directory.
This patch was originally meant as a workaround for that bug, but
it has now been solved in a different way. However, I still think
it makes sense as a cleanup to consolidate all sample code in
one place.

Pull i2c updates from Wolfram Sang:
- Peter Rosin did some major rework on the locking of i2c muxes by
seperating parent-locked muxes and mux-locked muxes.
This avoids deadlocks/workarounds when the mux itself needs i2c
commands for muxing. And as a side-effect, other workarounds in the
media layer could be eliminated. Also, Peter stepped up as the i2c
mux maintainer and will keep an eye on these changes.
- major updates to the octeon driver
- add a helper to the core to generate the address+rw_bit octal and
make drivers use it
- quite a bunch of driver updates

Make it possible to transfer i2c message buffers via DMA.
Start/Stop/Sending_Slave_Address and some data is still handled using
the old state machine, it is sending the bulk of the data that is done
via DMA.
The first byte of a transmission and the last two bytes of reception are
sent/received using PIO. This is needed for the HW to have access to the
first byte before DMA transmit and to be able to set the STOP condition
for DMA reception.

The root i2c adapter lock is then no longer held by the i2c mux during
accesses behind the i2c gate, and such accesses need to take that lock
just like any other ordinary i2c accesses do.
So, declare the i2c gate mux-locked, and zap the regmap overrides
that makes the i2c accesses unlocked and use plain old regmap
accesses. This also removes the need for the regmap wrappers used by
rtl2832_sdr, so deconvolute the code further and provide the regmap
handle directly instead of the wrapper functions.
