linux/types.h: enable endian checks for all sparse builds
By now, linux is mostly endian-clean. Enabling endian-ness
checks for everyone produces about 200 new sparse warnings for me -
less than 10% over the 2000 sparse warnings already there.
Not a big deal, OTOH enabling this helps people notice
they are introducing new bugs.
So let's just drop __CHECK_ENDIAN__. Follow-up patches
can drop distinction between __bitwise and __bitwise__.

This patch introduces virtio-crypto driver for Linux Kernel.
The virtio crypto device is a virtual cryptography device
as well as a kind of virtual hardware accelerator for
virtual machines. The encryption anddecryption requests
are placed in the data queue and are ultimately handled by
thebackend crypto accelerators. The second queue is the
control queue used to create or destroy sessions for
symmetric algorithms and will control some advanced features
in the future. The virtio crypto device provides the following
cryptoservices: CIPHER, MAC, HASH, and AEAD.

Pull i2c updates from Wolfram Sang:
- the first series of making i2c_device_id optional instead of
mandatory (in favor of alternatives like of_device_id).
This involves adding a new probe callback (probe_new) which removes
some peculiarities I2C had for a long time now. The new probe is
matching the other subsystems now and the old one will be removed
once all users are converted. It is expected to take a while but
there is ongoing interest in that.
- SMBus Host Notify introduced 4.9 got refactored. They are now using
interrupts instead of the alert callback which solves multiple
issues.
- new drivers for iMX LowPower I2C, Mellanox CPLD and its I2C mux
- significant refactoring for bcm2835 driver

driver-api: create an edac.rst file with EDAC documentation
Currently, there's no device driver documentation for the EDAC
subsystem at the driver-api book. Fill in the blanks for the
structures and functions that misses documentation, uniform
the word on the existing ones, and add a new edac.rst file at
driver-api, in order to document the EDAC subsystem.
The edac.txt assumes that the reader has already deep knowledge
on RAS features. However, this may not be the case. So, add an
introduction chapter explaining the main concepts that are used by
the EDAC subsystem and by other RAS drivers within the Kernel.
edac.txt: update information about newer Intel CPUs
There's a chapter at edac.rst written by the time Nehalem
support was added. Such information is used not only by the
Nehalem driver (i7core_edac), but by all newer Intel CPU
architectures that are supported by i7core_edac, sb_edac
and sbx_edac drivers.
edac.txt: remove info that the Nehalem EDAC is experimental
This driver has been there for almost 3 years, without any
conceptual changes. So, it is not experimental anymore, and
won't likely have any changes at the API or on log outputs.
Converts the EDAC driver subsystem documentation to ReST:
- Put paragraph titles in lower case;
- Add code blocks where needed;
- Convert tables to ReST markup;
- Mark filesystem and module names as verbatim;
- Adjust document to be properly displayed in html.
edac.txt: add a section explaining the dimmX and rankX directories
Documentation for those are missing at the EDAC description.
I guess we end by moving such descriptions in the past to the
ABI document (or only added it there), but it means that the
EDAC documentation is incomplete. So, add it there.

printk: remove console flushing special cases for partial buffered lines
It actively hurts proper merging, and makes for a lot of special cases.
There was a good(ish) reason for doing it originally, but it's getting
too painful to maintain. And most of the original reasons for it are
long gone.
So instead of having special code to flush partial lines to the console
(as opposed to the record buffers), do _all_ the console writing from
the record buffer, and be done with it.
If an oops happens (or some other synchronous event), we will flush the
partial lines due to the oops printing activity, so this does not affect
that. It does mean that if you have a completely hung machine, a
partial preceding line may not have been printed out.
That was some of the original reason for this complexity, in fact, back
when we used to test for the historical i386 "halt" instruction problem
by doing
and that model no longer works (it the 'hlt' instruction kills the
machine, the partial line won't have been flushed, so you won't even see
it).
Of course, that was also back in the days when people actually had
textual console output rather than a graphical splash-screen at bootup.
How times change..

printk: remove games with previous record flags
The record logging code looks at the previous record flags in various
ways, and they are all wrong.
You can't use the previous record flags to determine anything about the
next record, because they may simply not be related. In particular, the
reason the previous record was a continuation record may well be exactly
_because_ the new record was printed by a different process, which is
why the previous record was flushed.
So all those games are simply wrong, and make the code hard to
understand (because the code fundamentally cdoes not make sense).

use IPMI internally (like with ACPI) and don't need a device interface
or the added possible security entry. A softdep should make it work
'out of the box' but allow people to not have it if they don't want
it"

ipmi: create hardware-independent softdep for ipmi_devintf
ipmi: Fix sequence number handling
ipmi: Pick up slave address from SMBIOS on an ACPI device
ipmi_si: Clean up printks
Move platform device creation earlier in the initialization
ipmi: Update documentation
ipmi_ssif: Remove an unused module parameter
ipmi: Periodically check for events, not messages
Logfs was introduced to the kernel in 2009, and hasn't seen any non
drive-by changes since 2012, while having lots of unsolved issues
including the complete lack of error handling, with more and more
issues popping up without any fixes.
The logfs.org domain has been bouncing from a mail, and the maintainer
on the non-logfs.org domain hasn't repsonded to past queries either.

Merge tag 'dmaengine-4.10-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul:
"Fairly routine update this time around with all changes specific to
drivers:
- New driver for STMicroelectronics FDMA
- Memory-to-memory transfers on dw dmac
- Support for slave maps on pl08x devices
- Bunch of driver fixes to use dma_pool_zalloc
- Bunch of compile and warning fixes spread across drivers"
[ The ST FDMA driver already came in earlier through the remoteproc tree ]
