Pull VFIO updates from Alex Williamson:
- VFIO updates for v4.10 primarily include a new Mediated Device
interface, which essentially allows software defined devices to be
exposed to users through VFIO. The host vendor driver providing this
virtual device polices, or mediates user access to the device.
These devices often incorporate portions of real devices, for
instance the primary initial users of this interface expose vGPUs
which allow the user to map mediated devices, or mdevs, to a portion
of a physical GPU. QEMU composes these mdevs into PCI representations
using the existing VFIO user API. This enables both Intel KVM-GT
support, which is also expected to arrive into Linux mainline during
the v4.10 merge window, as well as NVIDIA vGPU, and also Channel I/O
devices (aka CCW devices) for s390 virtualization support. (Kirti
Wankhede, Neo Jia)

- Fixes to VFIO capability chain handling (Eric Auger)

Pull clk updates from Stephen Boyd:
"This is a fairly quiet release. We don't have any patches to the core
framework. The only patch that can even be considered "core" adds
another clk_get() variant. The rest of the changes are in drivers for
various SoCs, and we have a few bits for ARM shmobile architecture
code (dts and mach) due to the dependency we're breaking between
shmobile architecture code and its clk driver. Those shmobile bits
have also been pulled into arm-soc tree. Here's the summary:

Pull remoteproc updates from Bjorn Andersson:
- introduce remoteproc "subdevice" support, which allows remoteproc
driver to associate devices to the "running" state of the remoteproc,
allowing devices to be probed and removed as the remote processor is
booted, shut down or recovering from a crash.
- handling of virtio device resources was improved, vring memory is now
allocated as part of other memory allocation. This ensures that all
vrings for all virtio devices are allocated before we boot the remote
processor.
- the debugfs mechanism for starting and stopping remoteproc instances
was replaced with a sysfs interface, also providing a mechanism for
specifying firmware to use by the instance. This allows user space to
load and boot use case specific firmware on remote processors.
- new drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as
removal of the unused StE modem loader.
- finally support for crash recovery in the Qualcomm Wirelss subsystem
(used for WiFi/BT/FM on a number of platforms) and a number of bug
fixes and cleanups

Pull pinctrl updates from Linus Walleij:
"Bulk pin control changes for the v4.10 kernel cycle:
No core changes this time. Mainly gradual improvement and
feature growth in the drivers.
New drivers:
- New driver for TI DA850/OMAP-L138/AM18XX pinconf
- The SX150x was moved over from the GPIO subsystem and reimagined as
a pin control driver with GPIO support in a joint effort by three
independent users of this hardware. The result was amazingly good!
- New subdriver for the Oxnas OX820
Improvements:
- The sunxi driver now supports the generic pin control bindings
rather than the sunxi-specific. Add debouncing support to the
driver.
- Simplifications in pinctrl-single adding a generic parser.
- Two downstream fixes and move the Raspberry Pi BCM2835 over to use
the generic GPIOLIB_IRQCHIP"

Pull GPIO updates from Luinus Walleij:
"Bulk GPIO changes for the v4.10 kernel cycle:
Core changes:
- Simplify threaded interrupt handling: instead of passing numbed
parameters to gpiochip_irqchip_add_chained() we create a new call:
gpiochip_irqchip_add_nested() so the two types are clearly
semantically different. Also make sure that all nested chips call
gpiochip_set_nested_irqchip() which is necessary for IRQ resend to
work properly if it happens.
- Return error on seek operations for the chardev.
- Clamp values set as part of gpio[d]_direction_output() so that
anything != 0 will be send down to the driver as "1" not the value
passed in.
- ACPI can now support naming of GPIO lines, hogs and holes in the
GPIO lists.
New drivers:
- The SX150x driver was deemed unfit for the GPIO subsystem and was
moved over to a combined GPIO+pinctrl driver in the pinctrl
subsystem.
New features:
- Various cleanups to various drivers"

We have observed page allocations failures of order 4 during core dump
while trying to allocate vma_filesz. This results in a useless core
file of size 0. To improve reliability use vmalloc().
Note that the vmalloc() allocation is bounded by sysctl_max_map_count,
which is 65,530 by default. So with a 4k page size, and 8 bytes per
seg, this is a max of 128 pages or an order 7 allocation. Other parts
of the core dump path, such as fill_files_note() are already using
vmalloc() for presumably similar reasons.

Jani Nikula proposes patches to add a few new letter prefixes for "B:"
bug reporting and "C:" maintainer chatting to the various sections of
MAINTAINERS.
Add a generic mechanism to get_maintainer.pl to find sections that have
any combination of "[A-Z]" letter prefix types in a section.

Add a configuration option to set the default console loglevel. This
is, as before, still possible to override at runtime through bootargs
(loglevel=<x>), sysrq and /proc/printk.
There are cases where adding additional arguments on the commandline is
impractical, and changing the default for the kernel when being built
makes more sense. Provide such a method here, for those who choose to
do so.
Also, while touching this code, clarify the difference between
MESSAGE_LOGLEVEL_DEFAULT and CONSOLE_LOGLEVEL_DEFAULT.

Commit 4bcc595ccd80 ("printk: reinstate KERN_CONT for printing
continuation lines") allows to define more message headers for a single
message. The motivation is that continuous lines might get mixed.
Therefore it make sense to define the right log level for every piece of
a cont line.
This patch allows to copy only the real message level. We should ignore
KERN_CONT because <filename:line> is added for each message. By other
words, we want to know where each piece of the line comes from.

message. The motivation is that continuous lines might get mixed.
Therefore it make sense to define the right log level for every piece of
a cont line.
The current btrfs_printk() macros do not support continuous lines at the
moment. But better be prepared for a custom messages and avoid
potential "lvl" buffer overflow.
This patch iterates over the entire message header. It is interested
only into the message level like the original code.
This patch also introduces PRINTK_MAX_SINGLE_HEADER_LEN. Three bytes
are enough for the message level header at the moment. But it used to
be three, see the commit 04d2c8c83d0e ("printk: convert the format for
KERN_<LEVEL> to a 2 byte pattern").
Also I fixed the default ratelimit level. It looked very strange when it
was different from the default log level.

This patch introduces printk_skip_headers() that will skip all headers
and uses it in the kdb code instead of printk_skip_level().
This approach helps to fix other printk_skip_level() users
independently.

Commit 4bcc595ccd80 ("printk: reinstate KERN_CONT for printing
continuation lines") added back KERN_CONT message header. As a result
it might appear in the middle of the line when the parts are squashed
via the temporary NMI buffer.
A reasonable solution seems to be to split the text in the NNI temporary
not only by newlines but also by the message headers.
Another solution would be to filter out KERN_CONT when writing to the
temporary buffer. But this would complicate the lockless handling.
Also it would not solve problems with a missing newline that was there
even before the KERN_CONT stuff.
This patch moves the temporary buffer handling into separate function.
I played with it and it seems that using the char pointers make the code
easier to read.
Also it prints the final newline as a continuous line.
Finally, it moves handling of the s->len overflow into the paranoid
check. And allows to recover from the disaster.

vsnprintf() adds the trailing '\0' but it does not count it into the
number of printed characters. The result is that there is one byte less
space for the real characters in the buffer.
The broken check for the free space might cause that we will repeatedly
try to print 1 character into the buffer, never reach the full buffer,
and do not count the messages as missed.
Also vsnprintf() returns the number of characters that would be printed
if the buffer was big enough. As a result, s->len might be bigger than
the size of the buffer[*]. And the printk() function might return
bigger len than it really printed. Both problems are fixed by using
vscnprintf() instead.
Note that I though about increasing the number of missed messages even
when the message was shrunken. But it made the code even more
complicated. I think that it is not worth it. Shrunken messages are
usually easy to recognize. And it should be a corner case.
[*] The overflown s->len value is crazy and unexpected. I "made a
mistake" and reported this situation as an internal error when fixed
handling of PR_CONT headers in some other patch.
