treewide: drop CONFIG_EMBEDDED

2023-08-21T20:46:25+00:00

There is only one Kconfig user of CONFIG_EMBEDDED and it can be switched to EXPERT or "if !ARCH_MULTIPLATFORM" (suggested by Arnd).

arch//configs/defconfig: Replace AUTOFS4_FS by AUTOFS_FS

2023-07-29T21:08:22+00:00

Commit a2225d931f75 ("autofs: remove left-over autofs4 stubs") promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS within a couple of releases, but five years later this still has not happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs. Get rid of it mechanically: git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' | xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/' Also just remove the AUTOFS4_FS config option stub. Anybody who hasn't regenerated their config file in the last five years will need to just get the new name right when they do.

mm/slab: rename CONFIG_SLAB to CONFIG_SLAB_DEPRECATED

2023-05-26T17:01:47+00:00

As discussed at LSF/MM [1] [2] and with no objections raised there, deprecate the SLAB allocator. Rename the user-visible option so that users with CONFIG_SLAB=y get a new prompt with explanation during make oldconfig, while make olddefconfig will just switch to SLUB. In all defconfigs with CONFIG_SLAB=y remove the line so those also switch to SLUB. Regressions due to the switch should be reported to linux-mm and slab maintainers.

mm, treewide: redefine MAX_ORDER sanely

2023-04-06T02:42:46+00:00

MAX_ORDER currently defined as number of orders page allocator supports: user can ask buddy allocator for page order between 0 and MAX_ORDER-1. This definition is counter-intuitive and lead to number of bugs all over the kernel. Change the definition of MAX_ORDER to be inclusive: the range of orders user can ask from buddy allocator is 0..MAX_ORDER now.

Pull USB and Thunderbolt driver updates from Greg KH: "Here is the large set of USB and Thunderbolt driver changes for 6.2-rc1. Overall, thanks to the removal of a driver, more lines were removed than added, a nice change. Highlights include: - removal of the sisusbvga driver that was not used by anyone anymore - minor thunderbolt driver changes and tweaks - chipidea driver updates - usual set of typec driver features and hardware support added - musb minor driver fixes - fotg210 driver fixes, bringing that hardware back from the "dead" - minor dwc3 driver updates - addition, and then removal, of a list.h helper function for many USB and other subsystem drivers, that ended up breaking the build.

mm, slob: rename CONFIG_SLOB to CONFIG_SLOB_DEPRECATED

2022-11-30T23:09:20+00:00

As explained in [1], we would like to remove SLOB if possible. - There are no known users that need its somewhat lower memory footprint so much that they cannot handle SLUB (after some modifications by the previous patches) instead. - It is an extra maintenance burden, and a number of features are incompatible with it. - It blocks the API improvement of allowing kfree() on objects allocated via kmem_cache_alloc(). As the first step, rename the CONFIG_SLOB option in the slab allocator configuration choice to CONFIG_SLOB_DEPRECATED. Add CONFIG_SLOB depending on CONFIG_SLOB_DEPRECATED as an internal option to avoid code churn. This will cause existing .config files and defconfigs with CONFIG_SLOB=y to silently switch to the default (and recommended replacement) SLUB, while still allowing SLOB to be configured by anyone that notices and needs it. But those should contact the slab maintainers and linux-mm@kvack.org as explained in the updated help. With no valid objections, the plan is to update the existing defconfigs to SLUB and remove SLOB in a few cycles. To make SLUB more suitable replacement for SLOB, a CONFIG_SLUB_TINY option was introduced to limit SLUB's memory overhead. There is a number of defconfigs specifying CONFIG_SLOB=y. As part of this patch, update them to select CONFIG_SLUB and CONFIG_SLUB_TINY.

mm: memcontrol: drop dead CONFIG_MEMCG_SWAP config symbol

2022-10-03T21:03:36+00:00

Since 2d1c498072de ("mm: memcontrol: make swap tracking an integral part of memory control"), CONFIG_MEMCG_SWAP hasn't been a user-visible config option anymore, it just means CONFIG_MEMCG && CONFIG_SWAP. Update the sites accordingly and drop the symbol. [ While touching the docs, remove two references to CONFIG_MEMCG_KMEM, which hasn't been a user-visible symbol for over half a decade. ] Link: https://lkml.kernel.org/r/20220926135704.400818-5-hannes@cmpxchg.org Signed-off-by: Johannes Weiner Acked-by: Shakeel Butt Cc: Hugh Dickins Cc: Michal Hocko Cc: Roman Gushchin Signed-off-by: Andrew Morton

treewide: defconfig: address renamed CONFIG_DEBUG_INFO=y

2022-09-12T04:55:05+00:00

CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT, DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5. This was actually not what I had in mind when I suggested making it a 'choice' statement, but it's too late to change again now, and the Kconfig logic is more sensible in the new form. Change any defconfig file that had CONFIG_DEBUG_INFO enabled but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain default.
