Pull initial SPDX identifiers from Greg KH:
"License cleanup: add SPDX license identifiers to some files

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 <5
lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.

For non */uapi/* files that summary was:

SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139

and resulted in the first patch in this series.

If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that
was:

SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930

and resulted in the second patch in this series.

- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:

SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1

and that resulted in the third patch in this series.

- when the two scanners agreed on the detected license(s), that
became the concluded license(s).

- when there was disagreement between the two scanners (one detected
a license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.

- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply
(and which scanner probably needed to revisit its heuristics).

- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.

- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases,
confirmation by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.
The Windriver scanner is based on an older version of FOSSology in
part, so they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot
checks in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect
the correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial
patch version early this week with:

- a full scancode scan run, collecting the matched texts, detected
license ids and scores

- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct

- reviewing anything where there was no detection but the patch
license was not GPL-2.0 WITH Linux-syscall-note to ensure that the
applied SPDX license was correct

This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

Merge branch 'dpaa_eth-next'

Madalin Bucur says:

====================
dpaa_eth: Add the QorIQ DPAA Ethernet driver

This patch series adds the Ethernet driver for the Freescale
QorIQ Data Path Acceleration Architecture (DPAA).

This version includes changes following the feedback received
on previous versions from Eric Dumazet, Bob Cochran, Joe Perches,
Paul Bolle, Joakim Tjernlund, Scott Wood, David Miller - thank you.

Together with the driver a managed version of alloc_percpu
is provided that simplifies the release of per-CPU memory.

The Freescale DPAA architecture consists in a series of hardware
blocks that support the Ethernet connectivity. The Ethernet driver
depends upon the following drivers that are currently in the Linux
kernel:
- Peripheral Access Memory Unit (PAMU)
drivers/iommu/fsl_*
- Frame Manager (FMan) added in v4.4
drivers/net/ethernet/freescale/fman
- Queue Manager (QMan), Buffer Manager (BMan) added in v4.9-rc1
drivers/soc/fsl/qbman

dpaa_eth interfaces mapping to FMan MACs:

dpaa_eth /eth0\ ... /ethN\
driver | | | |
------------- ---- ----------- ---- -------------
-Ports / Tx Rx \ ... / Tx Rx \

where the acronyms used above (and in the code) are:
DPAA = Data Path Acceleration Architecture
FMan = DPAA Frame Manager
QMan = DPAA Queue Manager
BMan = DPAA Buffers Manager
QMI = QMan interface in FMan
BMI = BMan interface in FMan
FMan SP = FMan Storage Profiles
MURAM = Multi-user RAM in FMan
FQ = QMan Frame Queue
Rx Dfl FQ = default reception FQ
Rx Err FQ = Rx error frames FQ
Tx Cnf FQ = Tx confirmation FQ
Tx FQs = transmission frame queues
dtsec = datapath three speed Ethernet controller (10/100/1000 Mbps)
tgec = ten gigabit Ethernet controller (10 Gbps)
memac = multirate Ethernet MAC (10/100/1000/10000)

Changes from v7:
- remove the debug option to use a common buffer pool for all the
interfaces

Changed from v6:
- fixed an issue on an error path in dpaa_set_mac_address()
- removed NDO operation definitions that were not needed
- sorted the local variable declarations
- cleaned up a few checkpatch checks
- removed friendly network interface naming code

Changes from v5:
- adapt to the latest Q/BMan drivers API
- use build_skb() on Rx path instead of buffer pool refill path
- proper support for multiple buffer pools
- align function, variable names, code cleanup
- driver file structure cleanup

Changes from v4:
- addressed feedback from Scott Wood and Joe Perches
- fixed spelling
- fixed leak of uninitialized stack to userspace
- fix prints
- replace raw_cpu_ptr() with this_cpu_ptr()
- remove _s from the end of structure names
- remove underscores at start of functions, goto labels
- remove likely in error paths
- use container_of() instead of open casts
- remove priv from the driver name
- move return type on same line with function name
- drop DPA_READ_SKB_PTR/DPA_WRITE_SKB_PTR

Changes from v3:
- removed bogus delay and comment in .ndo_stop implementation
- addressed minor issues reported by David Miller

Changes from v2:
- removed debugfs, moved exports to ethtool statistics
- removed congestion groups Kconfig params

Changes from v1:
- bpool level Kconfig options removed
- print format using pr_fmt, cleaned up prints
- __hot/__cold removed
- gratuitous unlikely() removed
- code style aligned, consistent spacing for declarations
- comment formatting
