2018-03-16CRIS: Drop support for the CRIS portJesper Nilsson
The port was added back in 2000 so it's no longer even a good source of inspiration for newer ports (if it ever was) The last SoC (ARTPEC-3) with a CRIS main CPU was launched in 2008. Coupled with time and working developer board hardware being in low supply, it's time to drop the port from Linux. So long and thanks for all the fish!

2017-11-08kbuild: clean up *.dtb and *.dtb.S patterns from top-level MakefileMasahiro Yamada
We need to add "clean-files" in Makfiles to clean up DT blobs, but we often miss to do so. Since there are no source files that end with .dtb or .dtb.S, so we can clean-up those files from the top-level Makefile.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
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.

2017-05-18devicetree: Move include prefixes from arch to separate directoryOlof Johansson
We use a directory under arch/$ARCH/boot/dts as an include path that has links outside of the subtree to find dt-bindings from under include/dt-bindings. That's been working well, but new DT architectures haven't been adding them by default. Recently there's been a desire to share some of the DT material between arm and arm64, which originally caused developers to create symlinks or relative includes between the subtrees. This isn't ideal -- it breaks if the DT files aren't stored in the exact same hierarchy as the kernel tree, and generally it's just icky. As a somewhat cleaner solution we decided to add a $ARCH/ prefix link once, and allow DTS files to reference dtsi (and dts) files in other architectures that way. Original approach was to create these links under each architecture, but it lead to the problem of recursive symlinks. As a remedy, move the include link directories out of the architecture trees into a common location. At the same time, they can now share one directory and one dt-bindings/ link as well.

2016-12-08cris: No need to append -O2 and $(LINUXINCLUDE)Paul Bolle
The make variables asflags-y and ccflags-y are appended with -O2 and $(LINUXINCLUDE). But the build already picks up -O2 from the top Makefile and $(LINUXINCLUDE) from scripts/Makefile.lib. The net effect is that -O2 and the (long) list of include directories are used twice. This is harmless but pointless. So stop appending to these flags.

If CONFIG_ETRAX_AXISFLASHMAP is not configured, the flash rescue image object file is empty. With recent versions of binutils, this results in the following build error. cris-linux-objcopy: error: the input file 'arch/cris/boot/rescue/rescue.o' has no sections This is seen, for example, when trying to build cris:allnoconfig with recently generated toolchains. Since it does not make sense to build a flash rescue image if there is no flash, only build it if CONFIG_ETRAX_AXISFLASHMAP is enabled.
