2023-07-30arch/*/configs/*defconfig: Replace AUTOFS4_FS by AUTOFS_FSSven Joachim1-1/+1
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.

2023-06-21powerpc: drop MPC85xx_CDS platform supportPaul Gortmaker1-52/+0
The MPC8541/8548/8555 Configurable Development System (CDS) were the vehicle used to provide evaluation of the 1st e500-v2 CPUs around 2007. Similar to the earlier MPC83xx-MDS systems we removed, the "brains" exist on a PCI-X card, but additional connectors exist to the right of the PCI-X slot, two structural metal pins are used to provide stability in a vertical ATX mounting, and the CPU is now on a daughter-card vs. a clamped down BGA. Given the extra complexity and risk of connector damage, the 8548CDS I had access to came pre-assembled in a basic white Antec case common for that era, and I'm inclined to assume that was the default. Power was typical "Pentium4" 2005 ATX - the main 20 pin connector went to the PCI ATX form factor backplane, and the 4 pin black/yellow went to the CPU card. Like previous evaluation boards, they attempted to provide break-out connectors for as many features as possible, and that made for a fairly complex looking system. In any case, these are over 15 years old, and fairly complex systems, originally made for a small group of industry related people, and made for use where quiet fan operation wasn't important. Given that, it makes sense to remove support from them in 2023.

2023-06-21powerpc: drop MPC8540_ADS and MPC8560_ADS platform supportPaul Gortmaker2-97/+0
Based on the revision history in the manual(s), these e500-v1 platforms were first available around 2002. Like a lot of evaluation boards, they attempted to provide break-out connectors for all possible features, and that combined with four PCI-X slots (and the age/era) meant for a considerably large board. As I recall it, from a Linux point of view, the biggest difference between 8540 and 8560 was in the UART implementation, and that is reflected in a diff of the defconfigs. In any case, these are over 20 years old, and by today's standards only have a small amount of DDR1 memory, and were not widely available. Given that, it makes sense to remove support from them in 2023.

2023-05-26mm/slab: rename CONFIG_SLAB to CONFIG_SLAB_DEPRECATEDVlastimil Babka1-1/+0
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.

git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - Yu Zhao's Multi-Gen LRU patches are here. They've been under test in linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam Howlett. An overlapping range-based tree for vmas. It it apparently slightly more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat at [1]. This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses clang-generated instrumentation to detect used-unintialized bugs down to the single bit level. KMSAN keeps finding bugs. New ones, as well as the legacy ones. - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of memory into THPs. - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support file/shmem-backed pages. - userfaultfd updates from Axel Rasmussen - zsmalloc cleanups from Alexey Romanov - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure - Huang Ying adds enhancements to NUMA balancing memory tiering mode's page promotion, with a new way of detecting hot pages. - memcg updates from Shakeel Butt: charging optimizations and reduced memory consumption. - memcg cleanups from Kairui Song. - memcg fixes and cleanups from Johannes Weiner. - Vishal Moola provides more folio conversions - Zhang Yi removed ll_rw_block() :( - migration enhancements from Peter Xu - migration error-path bugfixes from Huang Ying - Aneesh Kumar added ability for a device driver to alter the memory tiering promotion paths. For optimizations by PMEM drivers, DRM drivers, etc. - vma merging improvements from Jakub Matěn. - NUMA hinting cleanups from David Hildenbrand. - xu xin added aditional userspace visibility into KSM merging activity. - THP & KSM code consolidation from Qi Zheng. - more folio work from Matthew Wilcox. - KASAN updates from Andrey Konovalov. - DAMON cleanups from Kaixu Xia. - DAMON work from SeongJae Park: fixes, cleanups. - hugetlb sysfs cleanups from Muchun Song. - Mike Kravetz fixes locking issues in hugetlbfs and in hugetlb core.

2021-08-26powerpc: retire sbc8548 board supportPaul Gortmaker1-50/+0
The support was for this was mainlined 13 years ago, in v2.6.25 [0e0fffe88767] just around the ppc --> powerpc migration. I believe the board was introduced a year or two before that, so it is roughly a 15 year old platform - with the CPU speed and memory size that was typical for that era. I haven't had one of these boards for several years, and availability was discontinued several years before that. Given that, there is no point in adding a burden to testing coverage that builds all possible defconfigs, so it makes sense to remove it. Of course it will remain in the git history forever, for anyone who happens to find a functional board and wants to tinker with it.

There is going to be a bit more next week, essentially fixes that I still want to sort through and test. The biggest item this time is the support to build the ppc64 LE kernel with our new v2 ABI. We previously supported v2 userspace but the kernel itself was a tougher nut to crack. This is now sorted mostly thanks to Anton and Rusty. We also have a fairly big series from Cedric that add support for 64-bit LE zImage boot wrapper. This was made harder by the fact that traditionally our zImage wrapper was always 32-bit, but our new LE toolchains don't really support 32-bit anymore (it's somewhat there but not really "supported") so we didn't want to rely on it. This meant more churn that just endian fixes. This brings some more LE bits as well, such as the ability to run in LE mode without a hypervisor (ie. under OPAL firmware) by doing the right OPAL call to reinitialize the CPU to take HV interrupts in the right mode and the usual pile of endian fixes. There's another series from Gavin adding EEH improvements (one day we *will* have a release with less than 20 EEH patches, I promise!). Another highlight is the support for the "Split core" functionality on P8 by Michael. This allows a P8 core to be split into "sub cores" of 4 threads which allows the subcores to run different guests under KVM (the HW still doesn't support a partition per thread). And then the usual misc bits and fixes ..." [ Further delayed by gmail deciding that BenH is a dirty spammer.

2014-05-23powerpc/mpc85xx: add support for Keymile's kmcoge4 boardValentin Longchamp1-0/+225
This patch introduces the support for Keymile's kmcoge4 board which is the internal reference design for boards based on Freescale's P2040/P2041 SoCs. This internal reference design is named kmp204x. The peripherals used on this board are: - SPI NOR Flash as bootloader medium - NAND Flash with a ubi partition - 2 PCIe busses (hosts 1 and 3) - 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5) - 4 Local Bus windows, with one dedicated to the QRIO reset/power mgmt CPLD - 2 I2C busses - last but not least, the mandatory serial port The patch also adds a defconfig file for this reference design that is necessary because of the lowmem option that must be set higher due to the number of PCIe devices with big ioremapped mem ranges on the boad.

This reference board dates back to 2004, and is largely a legacy EOL product. The MPC8560 is a pre e500v2 CPU. The SBC8548 is a more modern, better e500v2 target for people to use as a reference board with today's kernels, should they require one. Removing support for it will also allow us to remove some sbc8560 specific quirk handling in 8250 UART code, and some MTD mapping support.
