2023-01-30gpio: Remove unused and obsoleted irq_to_gpio()Andy Shevchenko
irq_to_gpio() is legacy and unused API, remove it for good. This leaves gpio_to_irq() as it's used yet in many places. Nevertheless, removal of its counterpart is a good signal to whoever even trying to consider using them that do not.

This has resulted in a few other minor patch series being held over for next time. Multi-gen LRU still isn't merged as we were waiting for mapletree to stabilize. The current plan is to merge MGLRU into -mm soon and to later reintroduce mapletree, with a view to hopefully getting both into 6.1-rc1. Summary: - The usual batches of cleanups from Baoquan He, Muchun Song, Miaohe Lin, Yang Shi, Anshuman Khandual and Mike Rapoport - Some kmemleak fixes from Patrick Wang and Waiman Long - DAMON updates from SeongJae Park - memcg debug/visibility work from Roman Gushchin - vmalloc speedup from Uladzislau Rezki - more folio conversion work from Matthew Wilcox - enhancements for coherent device memory mapping from Alex Sierra - addition of shared pages tracking and CoW support for fsdax, from Shiyang Ruan - hugetlb optimizations from Mike Kravetz - Mel Gorman has contributed some pagealloc changes to improve latency and realtime behaviour. - mprotect soft-dirty checking has been improved by Peter Xu - Many other singleton patches all over the place" [ XFS merge from hell as per Darrick Wong in https://lore.kernel.org/all/YshKnxb4VwXycPO8@magnolia/ ] * tag 'mm-stable-2022-08-03' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (282 commits) tools/testing/selftests/vm/hmm-tests.c: fix build mm: Kconfig: fix typo mm: memory-failure: convert to pr_fmt() mm: use is_zone_movable_page() helper hugetlbfs: fix inaccurate comment in hugetlbfs_statfs() hugetlbfs: cleanup some comments in inode.c hugetlbfs: remove unneeded header file hugetlbfs: remove unneeded hugetlbfs_ops forward declaration hugetlbfs: use helper macro SZ_1{K,M} mm: cleanup is_highmem() mm/hmm: add a test for cross device private faults selftests: add soft-dirty into run_vmtests.sh selftests: soft-dirty: add test for mprotect mm/mprotect: fix soft-dirty check in can_change_pte_writable() mm: memcontrol: fix potential oom_lock recursion deadlock mm/gup.c: fix formatting in check_and_migrate_movable_page() xfs: fail dax mount if reflink is enabled on a partition mm/memcontrol.c: remove the redundant updating of stats_flush_threshold userfaultfd: don't fail on unrecognized features hugetlb_cgroup: fix wrong hugetlb cgroup numa stat ...

At that time, we were not ready for the migration due to old compilers. Recently, Jakob Koschel reported a bug in list_for_each_entry(), which leaks the invalid pointer out of the loop [2]. In the discussion, we agreed that the time had come. Now that GCC 5.1 is the minimum compiler version, there is nothing to prevent us from going to -std=gnu99, or even straight to -std=gnu11.

2022-03-13Kbuild: move to -std=gnu11Arnd Bergmann
During a patch discussion, Linus brought up the option of changing the C standard version from gnu89 to gnu99, which allows using variable declaration inside of a for() loop. While the C99, C11 and later standards introduce many other features, most of these are already available in gnu89 as GNU extensions as well. An earlier attempt to do this when gcc-5 started defaulting to -std=gnu11 failed because at the time that caused warnings about designated initializers with older compilers. Now that gcc-5.1 is the minimum compiler version used for building kernels, that is no longer a concern. Similarly, the behavior of 'inline' functions changes between gnu89 using gnu_inline behavior and gnu11 using standard c99+ behavior, but this was taken care of by defining 'inline' to include __attribute__((gnu_inline)) in order to allow building with clang a while ago. Nathan Chancellor reported a new -Wdeclaration-after-statement warning that appears in a system header on arm, this still needs a workaround. The differences between gnu99, gnu11, gnu1x and gnu17 are fairly minimal and mainly impact warnings at the -Wpedantic level that the kernel never enables. Between these, gnu11 is the newest version that is supported by all supported compiler versions, though it is only the default on gcc-5, while all other supported versions of gcc or clang default to gnu1x/gnu17.

2022-02-15docs/translations: Skip CJK contents if suitable fonts not foundAkira Yokosawa
On systems without "Noto Sans CJK" fonts, CJK chapters in translations.pdf are full of "TOFU" boxes, with a long build time and a large log file containing lots of missing-font warnings. Avoid such waste of time and resources by skipping CJK chapters when CJK fonts are not available. To skip whole chapters, change the definition of \kerneldocBegin{SC|TC|KR|JP} commands so that they can have an argument to be ignored. This works as far as the argument (#1) is not used in the command. In place of skipped contents, put a note on skipped contents at the beginning of the PDF. Change the call sites in index.rst of CJK translations accordingly. When CJK fonts are available, existing command definitions with no argument just work. LaTeX engine will see additional pairs of "{" and "}", which add a level of grouping without having any effect on typesetting.

2022-01-10Documentation: remove trivial treeJiri Kosina
As has been discussed some time ago on ksumitt-discuss@ mailinglist, the need for trivial tree diminished over time as all the tooling and processess became much more mature and it's quite natural these days for trivial patches to flow through subsystem trees anyway, so the spin-off of a trivial tree doesn't make sense any more, and is not worth the merge conflicts it might sometimes create. So remove any mentions of it from kernel documentation for good. Link: https://lore.kernel.org/all/nycvar.YFH.7.76.2104222334290.18270@cbobk.fhfr.pm/ Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2021-09-13Merge branch 'gcc-min-version-5.1' (make gcc-5.1 the minimum version)Linus Torvalds
Merge patch series from Nick Desaulniers to update the minimum gcc version to 5.1. This is some of the left-overs from the merge window that I didn't want to deal with yesterday, so it comes in after -rc1 but was sent before. Gcc-4.9 support has been an annoyance for some time, and with -Werror I had the choice of applying a fairly big patch from Kees Cook to remove a fair number of initializer warnings (still leaving some), or this patch series from Nick that just removes the source of the problem. The initializer cleanups might still be worth it regardless, but honestly, I preferred just tackling the problem with gcc-4.9 head-on. We've been more aggressiuve about no longer having to care about compilers that were released a long time ago, and I think it's been a good thing. I added a couple of patches on top to sort out a few left-overs now that we no longer support gcc-4.x. As noted by Arnd, as a result of this minimum compiler version upgrade we can probably change our use of '--std=gnu89' to '--std=gnu11', and finally start using local loop declarations etc. But this series does _not_ yet do that.
