Mon, 04 May 2026 03:00:00 +0200

LoongArch: Make CONFIG_64BIT as the default optionCONFIG_64BIT is the mandatory option before v7.0, but in v7.1-rc1 bothCONFIG_32BIT and CONFIG_64BIT are selectable and CONFIG_32BIT became thedefault option. This breaks existing configurations, so explicitly makeCONFIG_64BIT as the default option to keep existing behavior.Signed-off-by: Huacai Chen List of files: /linux/arch/loongarch/Kconfig

LoongArch: Add HIGHMEM (PKMAP and FIX_KMAP) supportAdd HIGHMEM (High Memory) support for LoongArch, mostly needed by 32BITkernel because the size of kernel virtual memory space is only 512MB andthe size of usable physical memory is only 256MB in this case.HIGHMEM adds permanent kernel mapping (PKMAP) and fixed kernel mapping(FIX_KMAP), which increase usable physical memory up to 2.25GB (2304MB).We can just use the generic copy_user_highpage(), so remove the customversion.Signed-off-by: Huacai Chen List of files: /linux/arch/loongarch/Kconfig

078f80f909ba9fa3060e89dc634ff4b1defc43d3 - mm: remove CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE

Thu, 19 Mar 2026 09:19:40 +0100

mm: remove CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVEPatch series "mm: remove CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE and cleanupCONFIG_MIGRATION".While working on memory hotplug code cleanups, I realized thatCONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE is not really required anymore.Changing that revealed some rather nasty looking CONFIG_MIGRATIONhandling.Let's clean that up by introducing a dedicated CONFIG_NUMA_MIGRATIONoption and reducing the dependencies that CONFIG_MIGRATION has.This patch (of 2):All architectures that select CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE alsoselect CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG. So we can just removeCONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE.For CONFIG_MIGRATION, make it depend on CONFIG_MEMORY_HOTREMOVE instead,and make CONFIG_MEMORY_HOTREMOVE select CONFIG_MIGRATION (just likeCONFIG_CMA and CONFIG_COMPACTION already do).We'll clean up CONFIG_MIGRATION next.Link: https://lkml.kernel.org/r/20260319-config_migration-v1-0-42270124966f@kernel.orgLink: https://lkml.kernel.org/r/20260319-config_migration-v1-1-42270124966f@kernel.orgSigned-off-by: David Hildenbrand (Arm) Acked-by: Zi Yan Reviewed-by: Lorenzo Stoakes (Oracle) Reviewed-by: Joshua Hahn Reviewed-by: Gregory Price Reviewed-by: Mike Rapoport (Microsoft) Reviewed-by: Jonathan Cameron Cc: Albert Ou Cc: Alexander Gordeev Cc: Alexandre Ghiti Cc: Alistair Popple Cc: "Borislav Petkov (AMD)" Cc: Byungchul Park Cc: Catalin Marinas Cc: Christian Borntraeger Cc: Heiko Carstens Cc: "H.
