mm: rename ARCH_ENABLE_THP_MIGRATION to ARCH_HAS_PMD_SOFTLEAVES

2026-07-07T23:43:06+00:00

CONFIG_ARCH_ENABLE_THP_MIGRATION gates PMD-level migration entries. PMD-level device-private entries use the same migration mechanism and therefore require the same architecture support. Upcoming PMD-level swap entries can use the same PMD softleaf helpers without depending on page migration, so rename the architecture gate to CONFIG_ARCH_HAS_PMD_SOFTLEAVES. This describes the PMD entry capability rather than one current user of it. This is a pure rename: the set of selecting architectures (x86, arm64, s390, riscv, loongarch, and powerpc on PPC_BOOK3S_64) and the gating semantics are unchanged. No functional change intended.

powerpc/kexec_file: Use crash_exclude_core_ranges() helper

2026-06-30T15:49:06+00:00

The crash memory exclude of crashk_res and crashk_cma memory on powerpc are almost identical to the generic crash_exclude_core_ranges(). By introducing the architecture-specific arch_crash_exclude_mem_range() function with a default implementation of crash_exclude_mem_range(), and using crash_exclude_mem_range_guarded as powerpc's separate implementation, the generic crash_exclude_core_ranges() helper function can be reused.

powerpc/crash: sort crash memory ranges before preparing elfcorehdr

2026-06-30T15:49:06+00:00

During a memory hot-remove event, the elfcorehdr is rebuilt to exclude the removed memory. While updating the crash memory ranges for this operation, the crash memory ranges array can become unsorted. This happens because remove_mem_range() may split a memory range into two parts and append the higher-address part as a separate range at the end of the array. So far, no issues have been observed due to the unsorted crash memory ranges. However, this could lead to problems once crash memory range removal is handled by generic code, as introduced in the upcoming patches in this series. Currently, powerpc uses a platform-specific function, remove_mem_range(), to exclude hot-removed memory from the crash memory ranges. This function performs the same task as the generic crash_exclude_mem_range() in crash_core.c. The generic helper also ensures that the crash memory ranges remain sorted. So remove the redundant powerpc-specific implementation and instead call crash_exclude_mem_range_guarded() (which internally calls crash_exclude_mem_range()) to exclude the hot-removed memory ranges.

PCI/sysfs: Convert legacy I/O and memory attributes to static definitions

2026-06-23T20:19:09+00:00

Currently, legacy_io and legacy_mem are dynamically allocated and created by pci_create_legacy_files(), with pci_adjust_legacy_attr() updating the attributes at runtime on Alpha to rename them and shift the size for sparse addressing. Convert to four static const attributes (legacy_io, legacy_io_sparse, legacy_mem, legacy_mem_sparse) with .is_bin_visible() callbacks that use pci_legacy_has_sparse() to select the appropriate variant per bus. The sizes are compile-time constants and .size is set directly on each attribute. Register the groups in pcibus_groups[] under a HAVE_PCI_LEGACY guard so the driver model handles creation and removal automatically. Stub out pci_create_legacy_files() and pci_remove_legacy_files() as the dynamic creation is no longer needed. Remove the __weak pci_adjust_legacy_attr(), Alpha's override, and its declaration from both Alpha and PowerPC asm/pci.h headers.
