mm: remove unneeded includes of Patch series "mm: cleanup usage of "Most architectures have very similar versions of pXd_alloc_one() andpXd_free_one() for intermediate levels of page table. These patches addgeneric versions of these functions in and enableuse of the generic functions where appropriate.In addition, functions declared and defined in headers areused mostly by core mm and early mm initialization in arch and there is noactual reason to have the included all over the place.The first patch in this series removes unneeded includes ofIn the end it didn't work out as neatly as I hoped and movingpXd_alloc_track() definitions to would requireunnecessary changes to arches that have custom page table allocations, soI've decided to move lib/ioremap.c to mm/ and make pgalloc-track.h localto mm/.This patch (of 8):In most cases header is required only for allocations ofpage table memory. Most of the .c files that include that header do notuse symbols declared in and do not require that header.As for the other header files that used to include , it ispossible to move that include into the .c file that actually uses symbolsfrom and drop the include from the header file.The process was somewhat automated using sed -i -E '/[<"]asm\/pgalloc\.h/d' \ $(grep -L -w -f /tmp/xx \ $(git grep -E -l '[<"]asm/pgalloc\.h'))where /tmp/xx contains all the symbols defined inarch/*/include/asm/pgalloc.h.[rppt@linux.ibm.com: fix powerpc warning]Signed-off-by: Mike Rapoport Signed-off-by: Andrew Morton Reviewed-by: Pekka Enberg Acked-by: Geert Uytterhoeven [m68k]Cc: Abdul Haleem Cc: Andy Lutomirski Cc: Arnd Bergmann Cc: Christophe Leroy Cc: Joerg Roedel Cc: Max Filippov Cc: Peter Zijlstra Cc: Satheesh Rajendran Cc: Stafford Horne Cc: Stephen Rothwell Cc: Steven Rostedt Cc: Joerg Roedel Cc: Matthew Wilcox Link: http://lkml.kernel.org/r/20200627143453.31835-1-rppt@kernel.orgLink: http://lkml.kernel.org/r/20200627143453.31835-2-rppt@kernel.orgSigned-off-by: Linus Torvalds List of files: /linux-6.15/arch/alpha/kernel/core_titan.c

7e1c4e27 - memblock: stop using implicit alignment to SMP_CACHE_BYTES

Tue, 30 Oct 2018 22:09:57 +0000

memblock: stop using implicit alignment to SMP_CACHE_BYTESWhen a memblock allocation APIs are called with align = 0, the alignmentis implicitly set to SMP_CACHE_BYTES.Implicit alignment is done deep in the memblock allocator and it cancome as a surprise. Not that such an alignment would be wrong evenwhen used incorrectly but it is better to be explicit for the sake ofclarity and the prinicple of the least surprise.Replace all such uses of memblock APIs with the 'align' parameterexplicitly set to SMP_CACHE_BYTES and stop implicit alignment assignmentin the memblock internal allocation functions.For the case when memblock APIs are used via helper functions, e.g. likeiommu_arena_new_node() in Alpha, the helper functions were detected withCoccinelle's help and then manually examined and updated whereappropriate.The direct memblock APIs users were updated using the semantic patch below:@@expression size, min_addr, max_addr, nid;@@(|- memblock_alloc_try_nid_raw(size, 0, min_addr, max_addr, nid)+ memblock_alloc_try_nid_raw(size, SMP_CACHE_BYTES, min_addr, max_addr,nid)|- memblock_alloc_try_nid_nopanic(size, 0, min_addr, max_addr, nid)+ memblock_alloc_try_nid_nopanic(size, SMP_CACHE_BYTES, min_addr, max_addr,nid)|- memblock_alloc_try_nid(size, 0, min_addr, max_addr, nid)+ memblock_alloc_try_nid(size, SMP_CACHE_BYTES, min_addr, max_addr, nid)|- memblock_alloc(size, 0)+ memblock_alloc(size, SMP_CACHE_BYTES)|- memblock_alloc_raw(size, 0)+ memblock_alloc_raw(size, SMP_CACHE_BYTES)|- memblock_alloc_from(size, 0, min_addr)+ memblock_alloc_from(size, SMP_CACHE_BYTES, min_addr)|- memblock_alloc_nopanic(size, 0)+ memblock_alloc_nopanic(size, SMP_CACHE_BYTES)|- memblock_alloc_low(size, 0)+ memblock_alloc_low(size, SMP_CACHE_BYTES)|- memblock_alloc_low_nopanic(size, 0)+ memblock_alloc_low_nopanic(size, SMP_CACHE_BYTES)|- memblock_alloc_from_nopanic(size, 0, min_addr)+ memblock_alloc_from_nopanic(size, SMP_CACHE_BYTES, min_addr)|- memblock_alloc_node(size, 0, nid)+ memblock_alloc_node(size, SMP_CACHE_BYTES, nid))[mhocko@suse.com: changelog update][akpm@linux-foundation.org: coding-style fixes][rppt@linux.ibm.com: fix missed uses of implicit alignment] Link: http://lkml.kernel.org/r/20181016133656.GA10925@rapoport-lnxLink: http://lkml.kernel.org/r/1538687224-17535-1-git-send-email-rppt@linux.vnet.ibm.comSigned-off-by: Mike Rapoport Suggested-by: Michal Hocko Acked-by: Paul Burton [MIPS]Acked-by: Michael Ellerman [powerpc]Acked-by: Michal Hocko Cc: Catalin Marinas Cc: Chris Zankel Cc: Geert Uytterhoeven Cc: Guan Xuetao Cc: Ingo Molnar Cc: Matt Turner Cc: Michal Simek Cc: Richard Weinberger Cc: Russell King Cc: Thomas Gleixner Cc: Tony Luck Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/arch/alpha/kernel/core_titan.c

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/alpha/kernel/core_titan.c

025a2215 - ALPHA: support graphics on non-zero PCI domains

Fri, 01 Jun 2007 07:47:03 +0000

ALPHA: support graphics on non-zero PCI domainsThis code replaces earlier and incomplete handling of graphics on non-zero PCIdomains (aka hoses or peer PCI buses).An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or akernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whoseSRM consoles are capable of configuring and handling graphics options onnon-zero hoses. All other machines have the option set FALSE.A routine, "find_console_vga_hose()", is used to find the graphics devicewhich the machine's firmware believes is the console device, and it sets aglobal (pci_vga_hose) for later use in managing access to the device. This iscalled in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use acustom version of this routine because of extra complexity.A routine, "locate_and_init_vga()", is used to find the graphics device andset a global (pci_vga_hose) for later use in managing access to the device, inthe case where "find_console_vga_hose" has failed.Various adjustments are made to the ioremap and ioportmap routines fordetecting and translating "legacy" VGA register and memory references to thereal PCI domain.[akpm@linux-foundation.org: don't statically init bss][akpm@linux-foundation.org: build fix]Signed-off-by: Jay Estabrook Signed-off-by: Ivan Kokshaysky Cc: Richard Henderson Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/arch/alpha/kernel/core_titan.c
