- 875fa64577da ("mm/hugetlb_vmemmap: fix race with speculative PFN
walkers") is known to cause a performance regression (https://lore.kernel.org/all/3acefad9-96e5-4681-8014-827d6be71c7a@linux.ibm.com/T/#mfa809800a7862fb5bdf834c6f71a3a5113eb83ff). Yu has a fix which I'll send along later via the hotfixes branch. - In the series "mm: Avoid possible overflows in dirty throttling" Jan Kara addresses a couple of issues in the writeback throttling code. These fixes are also targetted at -stable kernels. - Ryusuke Konishi's series "nilfs2: fix potential issues related to reserved inodes" does that. This should actually be in the mm-nonmm-stable tree, along with the many other nilfs2 patches. My bad. - More folio conversions from Kefeng Wang in the series "mm: convert to folio_alloc_mpol()" - Kemeng Shi has sent some cleanups to the writeback code in the series "Add helper functions to remove repeated code and improve readability of cgroup writeback" - Kairui Song has made the swap code a little smaller and a little faster in the series "mm/swap: clean up and optimize swap cache index". - In the series "mm/memory: cleanly support zeropage in vm_insert_page*(), vm_map_pages*() and vmf_insert_mixed()" David Hildenbrand has reworked the rather sketchy handling of the use of the zeropage in MAP_SHARED mappings. I don't see any runtime effects here - more a cleanup/understandability/maintainablity thing. - Dev Jain has improved selftests/mm/va_high_addr_switch.c's handling of higher addresses, for aarch64. The (poorly named) series is "Restructure va_high_addr_switch". - The core TLB handling code gets some cleanups and possible slight optimizations in Bang Li's series "Add update_mmu_tlb_range() to simplify code". - Jane Chu has improved the handling of our fake-an-unrecoverable-memory-error testing feature MADV_HWPOISON in the series "Enhance soft hwpoison handling and injection". - Jeff Johnson has sent a billion patches everywhere to add MODULE_DESCRIPTION() to everything. Some landed in this pull. - In the series "mm: cleanup MIGRATE_SYNC_NO_COPY mode", Kefeng Wang has simplified migration's use of hardware-offload memory copying. - Yosry Ahmed performs more folio API conversions in his series "mm: zswap: trivial folio conversions". - In the series "large folios swap-in: handle refault cases first", Chuanhua Han inches us forward in the handling of large pages in the swap code. This is a cleanup and optimization, working toward the end objective of full support of large folio swapin/out. - In the series "mm,swap: cleanup VMA based swap readahead window calculation", Huang Ying has contributed some cleanups and a possible fixlet to his VMA based swap readahead code. - In the series "add mTHP support for anonymous shmem" Baolin Wang has taught anonymous shmem mappings to use multisize THP. By default this is a no-op - users must opt in vis sysfs controls. Dramatic improvements in pagefault latency are realized. - David Hildenbrand has some cleanups to our remaining use of page_mapcount() in the series "fs/proc: move page_mapcount() to fs/proc/internal.h". - David also has some highmem accounting cleanups in the series "mm/highmem: don't track highmem pages manually". - Build-time fixes and cleanups from John Hubbard in the series "cleanups, fixes, and progress towards avoiding "make headers"". - Cleanups and consolidation of the core pagemap handling from Barry Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers and utilize them". - Lance Yang's series "Reclaim lazyfree THP without splitting" has reduced the latency of the reclaim of pmd-mapped THPs under fairly common circumstances. A 10x speedup is seen in a microbenchmark. It does this by punting to aother CPU but I guess that's a win unless all CPUs are pegged. - hugetlb_cgroup cleanups from Xiu Jianfeng in the series "mm/hugetlb_cgroup: rework on cftypes". - Miaohe Lin's series "Some cleanups for memory-failure" does just that thing. - Is anyone reading this stuff? If so, email me! - Someone other than SeongJae has developed a DAMON feature in Honggyu Kim's series "DAMON based tiered memory management for CXL memory". This adds DAMON features which may be used to help determine the efficiency of our placement of CXL/PCIe attached DRAM. - DAMON user API centralization and simplificatio work in SeongJae Park's series "mm/damon: introduce DAMON parameters online commit function". - In the series "mm: page_type, zsmalloc and page_mapcount_reset()" David Hildenbrand does some maintenance work on zsmalloc - partially modernizing its use of pageframe fields. - Kefeng Wang provides more folio conversions in the series "mm: remove page_maybe_dma_pinned() and page_mkclean()". - More cleanup from David Hildenbrand, this time in the series "mm/memory_hotplug: use PageOffline() instead of PageReserved() for !ZONE_DEVICE". It "enlightens memory hotplug more about PageOffline() pages" and permits the removal of some virtio-mem hacks. - Barry Song's series "mm: clarify folio_add_new_anon_rmap() and __folio_add_anon_rmap()" is a cleanup to the anon folio handling in preparation for mTHP (multisize THP) swapin. - Kefeng Wang's series "mm: improve clear and copy user folio" implements more folio conversions, this time in the area of large folio userspace copying. - The series "Docs/mm/damon/maintaier-profile: document a mailing tool and community meetup series" tells people how to get better involved with other DAMON developers. From SeongJae Park. - A large series ("kmsan: Enable on s390") from Ilya Leoshkevich does that. - David Hildenbrand sends along more cleanups, this time against the migration code. The series is "mm/migrate: move NUMA hinting fault folio isolation + checks under PTL". - Jan Kara has found quite a lot of strangenesses and minor errors in the readahead code. He addresses this in the series "mm: Fix various readahead quirks". - SeongJae Park's series "selftests/damon: test DAMOS tried regions and {min,max}_nr_regions" adds features and addresses errors in DAMON's self testing code. - Gavin Shan has found a userspace-triggerable WARN in the pagecache code. The series "mm/filemap: Limit page cache size to that supported by xarray" addresses this. The series is marked cc:stable. - Chengming Zhou's series "mm/ksm: cmp_and_merge_page() optimizations and cleanup" cleans up and slightly optimizes KSM. - Roman Gushchin has separated the memcg-v1 and memcg-v2 code - lots of code motion. The series (which also makes the memcg-v1 code Kconfigurable) are "mm: memcg: separate legacy cgroup v1 code and put under config option" and "mm: memcg: put cgroup v1-specific memcg data under CONFIG_MEMCG_V1" - Dan Schatzberg's series "Add swappiness argument to memory.reclaim" adds an additional feature to this cgroup-v2 control file. - The series "Userspace controls soft-offline pages" from Jiaqi Yan permits userspace to stop the kernel's automatic treatment of excessive correctable memory errors. In order to permit userspace to monitor and handle this situation. - Kefeng Wang's series "mm: migrate: support poison recover from migrate folio" teaches the kernel to appropriately handle migration from poisoned source folios rather than simply panicing. - SeongJae Park's series "Docs/damon: minor fixups and improvements" does those things. - In the series "mm/zsmalloc: change back to per-size_class lock" Chengming Zhou improves zsmalloc's scalability and memory utilization. - Vivek Kasireddy's series "mm/gup: Introduce memfd_pin_folios() for pinning memfd folios" makes the GUP code use FOLL_PIN rather than bare refcount increments. So these paes can first be moved aside if they reside in the movable zone or a CMA block. - Andrii Nakryiko has added a binary ioctl()-based API to /proc/pid/maps for much faster reading of vma information. The series is "query VMAs from /proc/<pid>/maps". - In the series "mm: introduce per-order mTHP split counters" Lance Yang improves the kernel's presentation of developer information related to multisize THP splitting. - Michael Ellerman has developed the series "Reimplement huge pages without hugepd on powerpc (8xx, e500, book3s/64)". This permits userspace to use all available huge page sizes. - In the series "revert unconditional slab and page allocator fault injection calls" Vlastimil Babka removes a performance-affecting and not very useful feature from slab fault injection. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCZp2C+QAKCRDdBJ7gKXxA joTkAQDvjqOoFStqk4GU3OXMYB7WCU/ZQMFG0iuu1EEwTVDZ4QEA8CnG7seek1R3 xEoo+vw0sWWeLV3qzsxnCA1BJ8cTJA8= =z0Lf -----END PGP SIGNATURE----- Merge tag 'mm-stable-2024-07-21-14-50' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - In the series "mm: Avoid possible overflows in dirty throttling" Jan Kara addresses a couple of issues in the writeback throttling code.

kbuild: add script and target to generate pacman package
pacman is the package manager used by Arch Linux and its derivates. Creating native packages from the kernel tree has multiple advantages: * The package triggers the correct hooks for initramfs generation and bootloader configuration * Uninstallation is complete and also invokes the relevant hooks * New UAPI headers can be installed without any manual bookkeeping The PKGBUILD file is a modified version of the one used for the downstream Arch Linux "linux" package. Extra steps that should not be necessary for a development kernel have been removed and an UAPI header package has been added.

ARM:
* Initial infrastructure for shadow stage-2 MMUs, as part of nested virtualization enablement * Support for userspace changes to the guest CTR_EL0 value, enabling (in part) migration of VMs between heterogenous hardware * Fixes + improvements to pKVM's FF-A proxy, adding support for v1.1 of the protocol * FPSIMD/SVE support for nested, including merged trap configuration and exception routing * New command-line parameter to control the WFx trap behavior under KVM * Introduce kCFI hardening in the EL2 hypervisor * Fixes + cleanups for handling presence/absence of FEAT_TCRX * Miscellaneous fixes + documentation updates LoongArch: * Add paravirt steal time support. * Add support for KVM_DIRTY_LOG_INITIALLY_SET. * Add perf kvm-stat support for loongarch. RISC-V: * Redirect AMO load/store access fault traps to guest * perf kvm stat support * Use guest files for IMSIC virtualization, when available ONE_REG support for the Zimop, Zcmop, Zca, Zcf, Zcd, Zcb and Zawrs ISA extensions is coming through the RISC-V tree. s390: * Assortment of tiny fixes which are not time critical x86: * Fixes for Xen emulation. * Add a global struct to consolidate tracking of host values, e.g. EFER * Add KVM_CAP_X86_APIC_BUS_CYCLES_NS to allow configuring the effective APIC bus frequency, because TDX. * Print the name of the APICv/AVIC inhibits in the relevant tracepoint. * Clean up KVM's handling of vendor specific emulation to consistently act on "compatible with Intel/AMD", versus checking for a specific vendor. * Drop MTRR virtualization, and instead always honor guest PAT on CPUs that support self-snoop. * Update to the newfangled Intel CPU FMS infrastructure. * Don't advertise IA32_PERF_GLOBAL_OVF_CTRL as an MSR-to-be-saved, as it reads '0' and writes from userspace are ignored. * Misc cleanups x86 - MMU: * Small cleanups, renames and refactoring extracted from the upcoming Intel TDX support. * Don't allocate kvm_mmu_page.shadowed_translation for shadow pages that can't hold leafs SPTEs. * Unconditionally drop mmu_lock when allocating TDP MMU page tables for eager page splitting, to avoid stalling vCPUs when splitting huge pages. * Bug the VM instead of simply warning if KVM tries to split a SPTE that is non-present or not-huge. KVM is guaranteed to end up in a broken state because the callers fully expect a valid SPTE, it's all but dangerous to let more MMU changes happen afterwards. x86 - AMD: * Make per-CPU save_area allocations NUMA-aware. * Force sev_es_host_save_area() to be inlined to avoid calling into an instrumentable function from noinstr code. * Base support for running SEV-SNP guests. API-wise, this includes a new KVM_X86_SNP_VM type, encrypting/measure the initial image into guest memory, and finalizing it before launching it. Internally, there are some gmem/mmu hooks needed to prepare gmem-allocated pages before mapping them into guest private memory ranges. This includes basic support for attestation guest requests, enough to say that KVM supports the GHCB 2.0 specification. There is no support yet for loading into the firmware those signing keys to be used for attestation requests, and therefore no need yet for the host to provide certificate data for those keys. To support fetching certificate data from userspace, a new KVM exit type will be needed to handle fetching the certificate from userspace. An attempt to define a new KVM_EXIT_COCO/KVM_EXIT_COCO_REQ_CERTS exit type to handle this was introduced in v1 of this patchset, but is still being discussed by community, so for now this patchset only implements a stub version of SNP Extended Guest Requests that does not provide certificate data. x86 - Intel: * Remove an unnecessary EPT TLB flush when enabling hardware. * Fix a series of bugs that cause KVM to fail to detect nested pending posted interrupts as valid wake eents for a vCPU executing HLT in L2 (with HLT-exiting disable by L1). * KVM: x86: Suppress MMIO that is triggered during task switch emulation Explicitly suppress userspace emulated MMIO exits that are triggered when emulating a task switch as KVM doesn't support userspace MMIO during complex (multi-step) emulation. Silently ignoring the exit request can result in the WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to userspace for some other reason prior to purging mmio_needed. See commit |

MTD changes:
- Nothing stands out for this merge window, mostly minor fixes, such as module descriptions, the use of debug macros and Makefile improvements. Raw NAND changes; - The Freescale MXC driver has been converted to the newer ->exec_op() interface. The meson driver now supports handling the boot ROM area with very specific ECC needs. Support for the iMX8QXP has been added to the GPMI driver. The lpx32xx driver now can get the DMA channels using DT entries. The Qcom binding has been improved to be more future proof by Rob. And then there is the usual load of misc and minor changes. SPI-NAND changes: - The Macronix vendor driver has been improved to support an extended ID to avoid conflicting with older devices after an ID reuse issue. SPI NOR changes: - Drop support for Xilinx S3AN flashes. These flashes are for the very old Xilinx Spartan 3 FPGAs and they need some awkward code in the core to support. Drop support for these flashes, along with the special handling we needed for them in the core like non-power-of-2 page size handling and the .setup() callback. - Fix regression for old w25q128 flashes without SFDP tables.

LoongArch: Make the users of larch_insn_gen_break() constant
LoongArch defines UPROBE_SWBP_INSN as a function call and this breaks
arch_uprobe_trampoline() which uses it to initialize a static variable.
Add the new "__builtin_constant_p" helper, __emit_break(), and redefine
the current users of larch_insn_gen_break() to use it.

LoongArch: Use rustc option -Zdirect-access-external-data
-Zdirect-access-external-data is a new Rust compiler option added in Rust 1.78, which we use to optimize the access of external data in the Linux kernel's Rust code. This patch modifies the Rust code in vmlinux to directly access externa data, using PC-REL instead of GOT. However, Rust code whithin modules is constrained by the PC-REL addressing range and is explicitly set to use an indirect method.

LoongArch: Add support for relocating the kernel with RELR relocation
RELR as a relocation packing format for relative relocations for reducing the size of relative relocation records. In a position independent executable there are often many relative relocation records, and our vmlinux is a PIE. The LLD linker (since 17.0.0) and the BFD linker (since 2.43) supports packing the relocations in the RELR format for LoongArch, with the flag -z pack-relative-relocs. Commits |

LoongArch: Automatically disable KASLR for hibernation
Hibernation assumes the memory layout after resume be the same as that before sleep, so it expects the kernel is loaded at the same position. To achieve this goal we automatically disable KASLR if user explicitly requests hibernation via the "resume=" command line. Since "nohibernate" and "noresume" have higher priorities than "resume=", we only disable KASLR if there is no "nohibernate" and "noresume". Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> |

LoongArch: Add ACPI standard hardware register based S3 support
Most LoongArch 64 machines are using custom "SADR" ACPI extension to perform ACPI S3 sleep. However the standard ACPI way to perform sleep is to write a value to ACPI PM1/SLEEP_CTL register, and this is never supported properly in kernel. Add standard S3 sleep by providing a default DoSuspend function which calls ACPI's acpi_enter_sleep_state() routine when SADR is not provided by the firmware. Also fix suspend assembly code so that ra is set properly before go into sleep routine. (Previously linked address of jirl was set to a0, some firmware do require return address in a0 but it's already set with la.pcrel before).

LoongArch: Always enumerate MADT and setup logical-physical CPU mapping
Some drivers want to use cpu_logical_map(), early_cpu_to_node() and some other CPU mapping APIs, even if we use "nr_cpus=1" to hard limit the CPU number. This is strongly required for the multi-bridges machines. Currently, we stop parsing the MADT if the nr_cpus limit is reached, but to achieve the above goal we should always enumerate the MADT table and setup logical-physical CPU mapping whether there is a nr_cpus limit. Rework the MADT enumeration: 1. Define a flag "cpu_enumerated" to distinguish the first enumeration (cpu_enumerated=0) and the physical hotplug case (cpu_enumerated=1) for set_processor_mask(). 2. If cpu_enumerated=0, stop parsing only when NR_CPUS limit is reached, so we can setup logical-physical CPU mapping; if cpu_enumerated=1, stop parsing when nr_cpu_ids limit is reached, so we can avoid some runtime bugs. Once logical-physical CPU mapping is setup, we will let cpu_enumerated=1. 3. Use find_first_zero_bit() instead of cpumask_next_zero() to find the next zero bit (free logical CPU id) in the cpu_present_mask, because cpumask_next_zero() will stop at nr_cpu_ids. 4. Only touch cpu_possible_mask if cpu_enumerated=0, this is in order to avoid some potential crashes, because cpu_possible_mask is marked as __ro_after_init. 5. In prefill_possible_map(), clear cpu_present_mask bits greater than nr_cpu_ids, in order to avoid a CPU be "present" but not "possible". Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> |

LoongArch: Define __ARCH_WANT_NEW_STAT in unistd.h
Chromium sandbox apparently wants to deny statx [1] so it could properly inspect arguments after the sandboxed process later falls back to fstat. Because there's currently not a "fd-only" version of statx, so that the sandbox has no way to ensure the path argument is empty without being able to peek into the sandboxed process's memory. For architectures able to do newfstatat though, glibc falls back to newfstatat after getting -ENOSYS for statx, then the respective SIGSYS handler [2] takes care of inspecting the path argument, transforming allowed newfstatat's into fstat instead which is allowed and has the same type of return value. But, as LoongArch is the first architecture to not have fstat nor newfstatat, the LoongArch glibc does not attempt falling back at all when it gets -ENOSYS for statx -- and you see the problem there! Actually, back when the LoongArch port was under review, people were aware of the same problem with sandboxing clone3 [3], so clone was eventually kept. Unfortunately it seemed at that time no one had noticed statx, so besides restoring fstat/newfstatat to LoongArch uapi (and postponing the problem further), it seems inevitable that we would need to tackle seccomp deep argument inspection. However, this is obviously a decision that shouldn't be taken lightly, so we just restore fstat/newfstatat by defining __ARCH_WANT_NEW_STAT in unistd.h. This is the simplest solution for now, and so we hope the community will tackle the long-standing problem of seccomp deep argument inspection in the future [4][5]. Also add "newstat" to syscall_abis_64 in Makefile.syscalls due to upstream asm-generic changes. More infomation please reading this thread [6].

Makefile: add comment to discourage tools/* addition for kernel builds
Kbuild provides scripts/Makefile.host to build host programs used for building the kernel. Unfortunately, there are two exceptions that opt out of Kbuild. The build system under tools/ is a cheesy replica, and cause issues. I was recently poked about a problem in the tools build system, which I do not maintain (and nobody maintains).
