mm: convert __HAVE_ARCH_TLB_REMOVE_TABLE to CONFIG_HAVE_ARCH_TLB_REMOVE_TABLE configFor architectures that define __HAVE_ARCH_TLB_REMOVE_TABLE, the pagetables at the pmd/pud level are generally not of struct ptdesc type, anddo not have pt_rcu_head member, thus these architectures cannot supportPT_RECLAIM.In preparation for enabling PT_RECLAIM on more architectures, convert__HAVE_ARCH_TLB_REMOVE_TABLE to CONFIG_HAVE_ARCH_TLB_REMOVE_TABLE config,so that we can make conditional judgments in Kconfig.Link: https://lkml.kernel.org/r/5ebfa3d4b56e63c6906bda5eccaa9f7194d3a86b.1769515122.git.zhengqi.arch@bytedance.comSigned-off-by: Qi Zheng Acked-by: David Hildenbrand (Arm) Tested-by: Andreas Larsson [sparc, UP&SMP]Acked-by: Andreas Larsson [sparc]Cc: "Aneesh Kumar K.V" Cc: Anton Ivanov Cc: Borislav Petkov Cc: Dave Hansen Cc: Dev Jain Cc: Helge Deller Cc: "H.

7303ecbfe4f46c00191b9b66acaa918784bad210 - mm: introduce CONFIG_ARCH_HAS_LAZY_MMU_MODE

Mon, 15 Dec 2025 16:03:15 +0100

mm: introduce CONFIG_ARCH_HAS_LAZY_MMU_MODEArchitectures currently opt in for implementing lazy_mmu helpers bydefining __HAVE_ARCH_ENTER_LAZY_MMU_MODE.In preparation for introducing a generic lazy_mmu layer that will requirestorage in task_struct, let's switch to a cleaner approach: instead ofdefining a macro, select a CONFIG option.This patch introduces CONFIG_ARCH_HAS_LAZY_MMU_MODE and has each archselect it when it implements lazy_mmu helpers. __HAVE_ARCH_ENTER_LAZY_MMU_MODE is removed and relies onthe new CONFIG instead.On x86, lazy_mmu helpers are only implemented if PARAVIRT_XXL is selected.This creates some complications in arch/x86/boot/, because a few filesmanually undefine PARAVIRT* options. As a result doesnot define the lazy_mmu helpers, but this breaks the build as only defines them if !CONFIG_ARCH_HAS_LAZY_MMU_MODE. There does not seem to be a clean way out of this - let's just undefinethat new CONFIG too.Link: https://lkml.kernel.org/r/20251215150323.2218608-7-kevin.brodsky@arm.comSigned-off-by: Kevin Brodsky Acked-by: David Hildenbrand Reviewed-by: Ritesh Harjani (IBM) Reviewed-by: Ryan Roberts Reviewed-by: Yeoreum Yun Acked-by: Andreas Larsson [sparc]Cc: Alexander Gordeev Cc: Anshuman Khandual Cc: Borislav Betkov Cc: Boris Ostrovsky Cc: Catalin Marinas Cc: Christophe Leroy Cc: David Hildenbrand (Red Hat) Cc: David S.
