2024-03-12selftests/mm: dont fail testsuite due to a lack of hugepagesNico Pache
Patch series "selftests/mm: Improve Hugepage Test Handling in MM Selftests", v2. This series addresses issues related to hugepage requirements in the MM selftests, ensuring tests are skipped rather than failing when the necessary hugepage count is not met. This adjustment allows for a more graceful handling for systems with insufficient hugepages, preventing unnecessary test failures and improving the overall robustness of the test suite. This patch (of 3): On systems that have large core counts and large page sizes, but limited memory, the userfaultfd test hugepage requirement is too large. Exiting early due to missing one test's requirements is a rather aggressive strategy, and prevents a lot of other tests from running. Remove the early exit to prevent this.

2024-03-12mm, vmscan: retry kswapd's priority loop with cache_trim_mode off on failureByungchul Park
With cache_trim_mode on, reclaim logic doesn't bother reclaiming anon pages. However, it should be more careful to use the mode because it's going to prevent anon pages from being reclaimed even if there are a huge number of anon pages that are cold and should be reclaimed. Even worse, that leads kswapd_failures to reach MAX_RECLAIM_RETRIES and stopping kswapd from functioning until direct reclaim eventually works to resume kswapd. So kswapd needs to retry its scan priority loop with cache_trim_mode off again if the mode doesn't work for reclaim. The problematic behavior can be reproduced by: CONFIG_NUMA_BALANCING enabled sysctl_numa_balancing_mode set to NUMA_BALANCING_MEMORY_TIERING numa node0 (8GB local memory, 16 CPUs) numa node1 (8GB slow tier memory, no CPUs) Sequence: 1) echo 3 > /proc/sys/vm/drop_caches 2) To emulate the system with full of cold memory in local DRAM, run the following dummy program and never touch the region: mmap(0, 8 * 1024 * 1024 * 1024, PROT_READ | PROT_WRITE, MAP_ANONYMOUS | MAP_PRIVATE | MAP_POPULATE, -1, 0); 3) Run any memory intensive work e.g. XSBench. 4) Check if numa balancing is working e.i. promotion/demotion. 5) Iterate 1) ~ 4) until numa balancing stops. With this, you could see that promotion/demotion are not working because kswapd has stopped due to ->kswapd_failures >= MAX_RECLAIM_RETRIES.

2024-03-12mm: add an explicit smp_wmb() to UFFDIO_CONTINUEJames Houghton
Users of UFFDIO_CONTINUE may reasonably assume that a write memory barrier is included as part of UFFDIO_CONTINUE. That is, a user may believe that all writes it has done to a page that it is now UFFDIO_CONTINUE'ing are guaranteed to be visible to anyone subsequently reading the page through the newly mapped virtual memory region. Today, such a user happens to be correct. mmget_not_zero(), for example, is called as part of UFFDIO_CONTINUE (and comes before any PTE updates), and it implicitly gives us a write barrier. To be resilient against future changes, include an explicit smp_wmb(). While we're at it, optimize the smp_wmb() that is already incidentally present for the HugeTLB case. Merely making a syscall does not generally imply the memory ordering constraints that we need (including on x86).

2024-03-12mm: fix list corruption in put_pages_listMatthew Wilcox (Oracle)
My recent change to put_pages_list() dereferences folio->lru.next after returning the folio to the page allocator. Usually this is now on the pcp list with other free folios, so we try to free an already-free folio. This only happens with lists that have more than 15 entries, so it wasn't immediately discovered. Revert to using list_for_each_safe() so we dereference lru.next before disposing of the folio.

2024-03-12cxl/region: Add memory hotplug notifier for cxl regionDave Jiang
When the CXL region is formed, the driver computes the performance data for the region. However this data is not available at the node data collection that has been populated by the HMAT during kernel initialization. Add a memory hotplug notifier to update the access coordinates to the 'struct memory_target' context kept by the HMAT_REPORTING code. Add CXL_CALLBACK_PRI for a memory hotplug callback priority. Set the priority number to be called before HMAT_CALLBACK_PRI. The CXL update must happen before hmat_callback(). A new HMAT_REPORTING helper hmat_update_target_coordinates() is added in order to allow CXL to update the memory_target access coordinates. A new ext_updated member is added to the memory_target to indicate that the access coordinates within the memory_target has been updated by an external agent such as CXL. This prevents data being overwritten by the hmat_update_target_attrs() triggered by hmat_callback(). Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Rafael J.

The difference between access class 0 and access class 1 for 'struct access_coordinate', if any, is that class 0 is for the distance from the target to the closest initiator and that class 1 is for the distance from the target to the closest CPU. For CXL memory, the nearest initiator may not necessarily be a CPU node. The performance path from the CXL endpoint to the host bridge should remain the same. However, the numbers extracted and stored from HMAT is the difference for the two access classes.

Pull SoC device tree updates from Arnd Bergmann: "There is very little going on with new SoC support this time, all the new chips are variations of others that we already support, and they are all based on ARMv8 cores: - Mediatek MT7981B (Filogic 820) and MT7988A (Filogic 880) are networking SoCs designed to be used in wireless routers, similar to the already supported MT7986A (Filogic 830). - NXP i.MX8DXP is a variant of i.MX8QXP, with two CPU cores less. These are used in many embedded and industrial applications. - Renesas R8A779G2 (R-Car V4H ES2.0) and R8A779H0 (R-Car V4M) are automotive SoCs. - TI J722S is another automotive variant of its K3 family, related to the AM62 series.

This is helpful with s390's FPU code where some users have up to 520 byte stack frames. Clearing such stack frames (if INIT_STACK_ALL_PATTERN or INIT_STACK_ALL_ZERO is enabled) before they are used contradicts the intention (performance improvement) of such code sections. - Convert switch_to() to an out-of-line function, and use the generic switch_to header file - Replace the usage of s390's debug feature with pr_debug() calls within the zcrypt device driver - Improve hotplug support of the Adjunct Processor device driver - Improve retry handling in the zcrypt device driver - Various changes to the in-kernel FPU code: - Make in-kernel FPU sections preemptible - Convert various larger inline assemblies and assembler files to C, mainly by using singe instruction inline assemblies. This increases readability, but also allows makes it easier to add proper instrumentation hooks - Cleanup of the header files - Provide fast variants of csum_partial() and csum_partial_copy_nocheck() based on vector instructions - Introduce and use a lock to synchronize accesses to zpci device data structures to avoid inconsistent states caused by concurrent accesses - Compile the kernel without -fPIE. This addresses the following problems if the kernel is compiled with -fPIE: - It uses dynamic symbols (.dynsym), for which the linker refuses to allow more than 64k sections.
