Pull staging and IIO updates from Greg KH:
"Here are the big staging/iio patches for 4.19-rc1.Lots of churn here, with tons of cleanups happening in staging
drivers, a removal of an old crypto driver that no one was using
(skein), and the addition of some new IIO drivers. Also added was a
"gasket" driver from Google that needs loads of work and the erofs
filesystem.Even with adding all of the new drivers and a new filesystem, we are
only adding about 1000 lines overall to the kernel linecount, which
shows just how much cleanup happened, and how big the unused crypto
driver was.All of these have been in the linux-next tree for a while now with no

This IP core has read and write AXI-Stream FIFOs, the contents of which can
be accessed from the AXI4 memory-mapped interface. This is useful for
transferring data from a processor into the FPGA fabric. The driver creates
a character device that can be read/written to with standard
open/read/write/close.See Xilinx PG080 document for IP details.

The Gasket (Google ASIC Software, Kernel Extensions, and Tools) kernel
framework is a generic, flexible system that supports thin kernel
drivers. Gasket kernel drivers are expected to handle opening and
closing devices, mmap'ing BAR space as requested, a small selection of
ioctls, and handling page table translation (covered below). Any other
functions should be handled by userspace code.The Gasket common module is not enough to run a device. In order to
customize the Gasket code for a given piece of hardware, a device
specific module must be created. At a minimum, this module must define a
struct gasket_driver_desc containing the device-specific data for use by
the framework; in addition, the module must declare an __init function
that calls gasket_register_device with the module's gasket_driver_desc
struct. Finally, the driver must define an exit function that calls
gasket_unregister_device with the module's gasket_driver_desc struct.One of the core assumptions of the Gasket framework is that precisely
one process is allowed to have an open write handle to the device node
at any given time. (That process may, once it has one write handle, open
any number of additional write handles.) This is accomplished by
tracking open and close data for each driver instance.Signed-off-by: Rob Springer

It's been four years since this was added. In the interim, skein has
not seen any mainstream adoption. Same with the threefish block cipher
upon which it's based.In the discussion over which hash algorithm will replace SHA1 in git,
it's not one of the contenders.There's absolutely no reason to think that there is anything wrong with
Skein or Threefish. The only reason for this removal is a lack of
adoption.If a real user comes forward, I'd be happy to assist with integrating

The Lustre filesystem has been in the kernel tree for over 5 years now.
While it has been an endless source of enjoyment for new kernel
developers learning how to do basic codingstyle cleanups, as well as an
semi-entertaining source of bewilderment from the vfs developers any
time they have looked into the codebase to try to figure out how to port
their latest api changes to this filesystem, it has not really moved
forward into the "this is in shape to get out of staging" despite many
half-completed attempts.And getting code out of staging is the main goal of that portion of the
kernel tree. Code should not stagnate and it feels like having this
code in staging is only causing the development cycle of the filesystem
to take longer than it should. There is a whole separate out-of-tree
copy of this codebase where the developers work on it, and then random
changes are thrown over the wall at staging at some later point in time.
This dual-tree development model has never worked, and the state of this
codebase is proof of that.So, let's just delete the whole mess. Now the lustre developers can go
off and work in their out-of-tree codebase and not have to worry about
providing valid changelog entries and breaking their patches up into
logical pieces. They can take the time they have spend doing those
types of housekeeping chores and get the codebase into a much better
shape, and it can be submitted for inclusion into the real part of the
kernel tree when ready.Cc: Oleg Drokin

The mtk-mmc driver does not support access to

bottom 512M (actually 448M due to 64M of IO space).

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if

This commit adds the vboxvideo drm/kms driver for the virtual graphics

that work on the driver can be easily shared.At the same time we want to take our time to get this driver properly
cleaned up (mainly converted to the new atomic modesetting APIs) before
submitting it as a normal driver under drivers/gpu/drm, putting this
driver in staging for now allows both.Note this driver has already been significantly cleaned up, when I started
