cf8e8658 - arch: Remove Itanium (IA-64) architecture

Thu, 20 Oct 2022 13:54:33 +0000

arch: Remove Itanium (IA-64) architectureThe Itanium architecture is obsolete, and an informal survey [0] revealsthat any residual use of Itanium hardware in production is mostly HP-UXor OpenVMS based. The use of Linux on Itanium appears to be limited toenthusiasts that occasionally boot a fresh Linux kernel to see whetherthings are still working as intended, and perhaps to churn out somedistro packages that are rarely used in practice.None of the original companies behind Itanium still produce or supportany hardware or software for the architecture, and it is listed as'Orphaned' in the MAINTAINERS file, as apparently, none of the engineersthat contributed on behalf of those companies (nor anyone else, for thatmatter) have been willing to support or maintain the architectureupstream or even be responsible for applying the odd fix. The Intelfirmware team removed all IA-64 support from the Tianocore/EDK2reference implementation of EFI in 2018. (Itanium is the originalarchitecture for which EFI was developed, and the way Linux supports itdeviates significantly from other architectures.) Some distros, such asDebian and Gentoo, still maintain [unofficial] ia64 ports, but many havedropped support years ago.While the argument is being made [1] that there is a 'for the commongood' angle to being able to build and run existing projects such as theGrid Community Toolkit [2] on Itanium for interoperability testing, thefact remains that none of those projects are known to be deployed onLinux/ia64, and very few people actually have access to such a system inthe first place. Even if there were ways imaginable in which Linux/ia64could be put to good use today, what matters is whether anyone isactually doing that, and this does not appear to be the case.There are no emulators widely available, and so boot testing Itanium isgenerally infeasible for ordinary contributors. GCC still supports IA-64but its compile farm [3] no longer has any IA-64 machines. GLIBC wouldlike to get rid of IA-64 [4] too because it would permit some overduecode cleanups. In summary, the benefits to the ecosystem of having IA-64be part of it are mostly theoretical, whereas the maintenance overheadof keeping it supported is real.So let's rip off the band aid, and remove the IA-64 arch code entirely.This follows the timeline proposed by the Debian/ia64 maintainer [5],which removes support in a controlled manner, leaving IA-64 in a knowngood state in the most recent LTS release. Other projects will followonce the kernel support is removed.[0] https://lore.kernel.org/all/CAMj1kXFCMh_578jniKpUtx_j8ByHnt=s7S+yQ+vGbKt9ud7+kQ@mail.gmail.com/[1] https://lore.kernel.org/all/0075883c-7c51-00f5-2c2d-5119c1820410@web.de/[2] https://gridcf.org/gct-docs/latest/index.html[3] https://cfarm.tetaneutral.net/machines/list/[4] https://lore.kernel.org/all/87bkiilpc4.fsf@mid.deneb.enyo.de/[5] https://lore.kernel.org/all/ff58a3e76e5102c94bb5946d99187b358def688a.camel@physik.fu-berlin.de/Acked-by: Tony Luck Signed-off-by: Ard Biesheuvel List of files: /linux-6.15/drivers/char/Makefile

9b12f050 - char: pcmcia: remove all the drivers

char: pcmcia: remove all the driversThese char PCMCIA drivers are buggy[1] and receive only minimal care. Itwas concluded[2], that we should try to remove most pcmcia driverscompletely. Let's start with these char broken one.Note that I also removed a UAPI header: include/uapi/linux/cm4000_cs.h.I found only coccinelle tests mentioning some ioctl constants from thatfile. But they are not actually used. Anyway, should someone complain,we may reintroduce the header (or its parts).[1] https://lore.kernel.org/all/f41c2765-80e0-48bc-b1e4-8cfd3230fd4a@www.fastmail.com/[2] https://lore.kernel.org/all/c5b39544-a4fb-4796-a046-0b9be9853787@app.fastmail.com/Signed-off-by: Jiri Slaby (SUSE) Cc: "Hyunwoo Kim" Cc: Harald Welte Cc: Lubomir Rintel Cc: Arnd Bergmann Cc: Greg Kroah-Hartman Acked-by: Dominik Brodowski Reviewed-by: Arnd Bergmann Link: https://lore.kernel.org/r/20230222092302.6348-2-jirislaby@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/char/Makefile

b2441318 - License cleanup: add SPDX GPL-2.0 license identifier to files with no license

Wed, 01 Nov 2017 14:07:57 +0000

License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseMany source files in the tree are missing licensing information, whichmakes it harder for compliance tools to determine the correct license.By default all files without license information are under the defaultlicense 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 bindingshorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart andPhilippe Ombredanne.How this work was done:Patches were generated and checked against linux-4.14-rc6 for a subset ofthe 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 caseswhere non-standard license headers were used, and references to licensehad to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied toa file was done in a spreadsheet of side by side results from of theoutput of two independent scanners (ScanCode & Windriver) producing SPDXtag:value files created by Philippe Ombredanne. Philippe prepared thebase 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 filesassessed. Kate Stewart did a file by file comparison of the scannerresults in the spreadsheet to determine which SPDX license identifier(s)to be applied to the file. She confirmed any determination that was notimmediately 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 licenseidentifiers 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 thespreadsheet to determine the SPDX license identifiers to apply to thesource files by Kate, Philippe, Thomas and, in some cases, confirmationby lawyers working with the Linux Foundation.Kate also obtained a third independent scan of the 4.13 code base fromFOSSology, and compared selected files where the other two scannersdisagreed against that SPDX file, to see if there was new insights. TheWindriver scanner is based on an older version of FOSSology in part, sothey are related.Thomas did random spot checks in about 500 files from the spreadsheetsfor the uapi headers and agreed with SPDX license identifier in thefiles he inspected. For the non-uapi files Thomas did random spot checksin about 15000 files.In initial set of patches against 4.14-rc6, 3 files were found to havecopy/paste license identifier errors, and have been fixed to reflect thecorrect identifier.Additionally Philippe spent 10 hours this week doing a detailed manualinspection and review of the 12,461 patched files from the initial patchversion 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 correctThis produced a worksheet with 20 files needing minor correction. Thisworksheet was then exported into 3 different .csv files for thedifferent types of files to be modified.These .csv files were then reviewed by Greg. Thomas wrote a script toparse the csv files and add the proper SPDX tag to the file, in theformat that the file expected. This script was further refined by Gregbased on the output to detect more types of files automatically and todistinguish between header and source .c files (which need differentcomment types.) Finally Greg ran the script using the .csv files togenerate the patches.Reviewed-by: Kate Stewart Reviewed-by: Philippe Ombredanne Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/char/Makefile
