dfad83cb - MIPS: Add support for CONFIG_DEBUG_VIRTUAL

Wed, 31 Mar 2021 03:22:07 +0000

MIPS: Add support for CONFIG_DEBUG_VIRTUALProvide hooks to intercept bad usages of virt_to_phys() and__pa_symbol() throughout the kernel. To make this possible, we need torename the current implement of virt_to_phys() into__virt_to_phys_nodebug() and wrap it around depending onCONFIG_DEBUG_VIRTUAL.A similar thing is needed for __pa_symbol() which is now aliased to__phys_addr_symbol() whose implementation is either the direct return ofRELOC_HIDE or goes through the debug version.Signed-off-by: Florian Fainelli Signed-off-by: Thomas Bogendoerfer List of files: /linux-6.15/arch/mips/mm/Makefile

446f062b - MIPS: use the generic get_user_pages_fast code

Fri, 12 Jul 2019 03:56:52 +0000

MIPS: use the generic get_user_pages_fast codeThe mips code is mostly equivalent to the generic one, minus variousbugfixes and an arch override for gup_fast_permitted.Note that this defines ARCH_HAS_PTE_SPECIAL for mips as mips haspte_special and pte_mkspecial implemented and used in the existing gupcode. They are no-op stubs, though which makes me a little unsure if thisis really right thing to do.Note that this also adds back a missing cpu_has_dc_aliases check for__get_user_pages_fast, which the old code was only doing forget_user_pages_fast. This clearly looks like an oversight, as anycondition that makes get_user_pages_fast unsafe also applies to__get_user_pages_fast.[hch@lst.de: MIPS: don't select ARCH_HAS_PTE_SPECIAL] Link: http://lkml.kernel.org/r/20190701151818.32227-3-hch@lst.deLink: http://lkml.kernel.org/r/20190625143715.1689-5-hch@lst.deSigned-off-by: Christoph Hellwig Reviewed-by: Jason Gunthorpe Tested-by: Guenter Roeck Cc: Ralf Baechle Cc: Andrey Konovalov Cc: Benjamin Herrenschmidt Cc: David Miller Cc: James Hogan Cc: Khalid Aziz Cc: Michael Ellerman Cc: Nicholas Piggin Cc: Paul Burton Cc: Paul Mackerras Cc: Rich Felker Cc: Yoshinori Sato Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/arch/mips/mm/Makefile

MIPS: remove mips_swiotlb_opsmips_swiotlb_ops differs from the generic swiotlb_dma_ops only in thatit contains a mb() barrier after each operations that maps or syncsdma memory to the device.The dma operations are defined to not be memory barriers, but insteadthe write* operations to kick the DMA off are supposed to contain them.For mips this handled by war_io_reorder_wmb(), which evaluates to thestronger wmb() instead of the pure compiler barrier barrier() forjust those platforms that use swiotlb, so I think we are coveredproperly.[paul.burton@mips.com: - Include linux/swiotlb.h to fix build failures for configs with CONFIG_SWIOTLB=y.]Signed-off-by: Christoph Hellwig Signed-off-by: Paul Burton Patchwork: https://patchwork.linux-mips.org/patch/20038/Cc: David Daney Cc: Huacai Chen Cc: linux-mips@linux-mips.orgCc: iommu@lists.linux-foundation.orgCc: linux-kernel@vger.kernel.org List of files: /linux-6.15/arch/mips/mm/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/arch/mips/mm/Makefile

The former is controlled with theCPU_MICROMIPS configuration setting, whereas SYS_SUPPORTS_MICROMIPS isused for the latter.Not only that, but with a given microMIPS vs standard MIPS kernelconfiguration only one microassembler is needed, that matches the ISAselected -- CP0.Config3.ISAOnExc is mandatory on microMIPS processors,so there is never a need to mix microMIPS and standard MIPS code.Consequently build only the microassembler that matches the ISA selectedfor the kernel.Signed-off-by: Maciej W.
