47512cfd0d x86/platform/goldfish: Prevent unconditional loading
The goldfish platform code registers the platform device unconditionally
which causes havoc in several ways if the goldfish_pdev_bus driver is
enabled:

 - Access to the hardcoded physical memory region, which is either not
   available or contains stuff which is completely unrelated.

 - Prevents that the interrupt of the serial port can be requested

 - In case of a spurious interrupt it goes into a infinite loop in the
   interrupt handler of the pdev_bus driver (which needs to be fixed
   seperately).

Add a 'goldfish' command line option to make the registration opt-in when
the platform is compiled in.

I'm seriously grumpy about this engineering trainwreck, which has seven
SOBs from Intel developers for 50 lines of code. And none of them figured
out that this is broken. Impressive fail!

89052d784b IB/cma: Add default RoCE TOS to CMA configfs
Add new entry to the RDMA-CM configfs that allows users
to select default TOS for RDMA-CM QPs.

This is useful for users that want to control the TOS for legacy
applications without changing their code.

Application that sets the TOS explicitly using the rdma_set_option
API will continue to work as expected, meaning overriding the configfs
value.

3821fd35b5 jump_label: Reduce the size of struct static_key
The static_key->next field goes mostly unused. The field is used for
associating module uses with a static key. Most uses of struct static_key
define a static key in the core kernel and make use of it entirely within
the core kernel, or define the static key in a module and make use of it
only from within that module. In fact, of the ~3,000 static keys defined,
I found only about 5 or so that did not fit this pattern.

Thus, we can remove the static_key->next field entirely and overload
the static_key->entries field. That is, when all the static_key uses
are contained within the same module, static_key->entries continues
to point to those uses. However, if the static_key uses are not contained
within the module where the static_key is defined, then we allocate a
struct static_key_mod, store a pointer to the uses within that
struct static_key_mod, and have the static key point at the static_key_mod.
This does incur some extra memory usage when a static_key is used in a
module that does not define it, but since there are only a handful of such
cases there is a net savings.

In order to identify if the static_key->entries pointer contains a
struct static_key_mod or a struct jump_entry pointer, bit 1 of
static_key->entries is set to 1 if it points to a struct static_key_mod and
is 0 if it points to a struct jump_entry. We were already using bit 0 in a
similar way to store the initial value of the static_key. This does mean
that allocations of struct static_key_mod and that the struct jump_entry
tables need to be at least 4-byte aligned in memory. As far as I can tell
all arches meet this criteria.

For my .config, the patch increased the text by 778 bytes, but reduced
the data + bss size by 14912, for a net savings of 14,134 bytes.

device-tree exposed configuration features have been tested on a i.MX6
platform with a USB2512B hub.

17f84b793c spi: lantiq-ssc: add support for Lantiq SSC SPI controller
This driver supports the Lantiq SSC SPI controller in master
mode. This controller is found on Intel (former Lantiq) SoCs like
the Danube, Falcon, xRX200, xRX300.

The hardware uses two hardware FIFOs one for received and one for
transferred bytes. When the driver writes data into the transmit FIFO
the complete word is taken from the FIFO into a shift register. The
data from this shift register is then written to the wire. This driver
uses the interrupts signaling the status of the FIFOs and not the shift
register. It is also possible to use the interrupts for the shift
register, but they will send a signal after every word. When using the
interrupts for the shift register we get a signal when the last word is
written into the shift register and not when it is written to the wire.
After all FIFOs are empty the driver busy waits till the hardware is
not busy any more and returns the transfer status.

853fe1bf75 cdrom: Make device operations read-only
Since function tables are a common target for attackers, it's best to keep
them in read-only memory. As such, this makes the CDROM device ops tables
const. This drops additionally n_minors, since it isn't used meaningfully,
and sets the only user of cdrom_dummy_generic_packet explicitly so the
variables can all be const.

Inspired by similar changes in grsecurity/PaX.

This new compatible, "allwinner,sun6i-a31-i2s", requires the
property "resets" which should be a phandle to the reset line.
Except these differences, the compatible is identical to previous one
which will not handle a reset line.

35879ee476 [media] videodev2.h: go back to limited range Y'CbCr for SRGB and, ADOBERGB
This reverts 'commit 7e0739cd9c40 ("[media] videodev2.h: fix
sYCC/AdobeYCC default quantization range").

The problem is that many drivers can convert R'G'B' content (often
from sensors) to Y'CbCr, but they all produce limited range Y'CbCr.

To stay backwards compatible the default quantization range for
sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full
range, even though the corresponding standards specify full range.

Update the V4L2_MAP_QUANTIZATION_DEFAULT define accordingly and
also update the documentation.

The children of cpcap, such as regulators, ADC and USB, can be just regular
device drivers and defined in the dts file. They get probed as we call
of_platform_populate() at the end of our probe, and then the children
can just call dev_get_regmap(dev.parent, NULL) to get the regmap.

6db6bd479d bindings: rtc: correct wrong reference in required properties
There are currently two broken bindings descriptions for RTC:

maxim,ds3231.txt
pcf8563.txt

They broke because of a improper RST documentation conversion with
commit 8c27ceff3604b2 ("docs: fix locations of several documents that got
moved") and now reference to a non-existing file:

Documentation/devicetree/bindings/i2c/trivial-admin-guide/devices.rst

However, the original reference to i2c/trivial-devices should have never
been made in the first place.

This change fixes this issue by replacing with correct descriptions.

baa6d39663 fpga: Add scatterlist based programming
Requiring contiguous kernel memory is not a good idea, this is a limited
resource and allocation can fail under normal work loads.

This introduces a .write_sg op that supporting drivers can provide
to DMA directly from dis-contiguous memory and a new entry point
fpga_mgr_buf_load_sg that users can call to directly provide page
lists.

The full matrix of compatibility is provided, either the linear or sg
interface can be used by the user with a driver supporting either
interface.

A notable change for drivers is that the .write op can now be called
multiple times.

3a08e93341 mtd: spi-nor: add dt support for Everspin MRAMs
The MR25 family doesn't support JEDEC, so they need explicit mentioning
in the list of supported spi IDs. This makes it possible to add these
using for example:

	compatible = "everspin,mr25h40";

There was already an entry for mr25h256. Move that one out of the "keep
for compatibility" section and put in a new group for Everspin MRAMs.
