v1: https://lore.kernel.org/linux-mm/20241219164425.2277022-1-kevin.brodsky@xxxxxxx/ This series should be considered in conjunction with Qi's series [1]. Together, they ensure that page table ctor/dtor are called at all levels (PTE to PGD) and all architectures, where page tables are regular pages. Besides the improvement in accounting and general cleanup, this also create a single place where construction/destruction hooks can be called for all page tables, namely the now-generic pagetable_dtor() introduced by Qi, and __pagetable_ctor() introduced in this series. v2 is essentially v1 rebased on top of mm-unstable, which includes Qi's v4 series. A number of patches from v1 were dropped: * v1 patch 4 is superseded by patch 6 in Qi's series. * v1 patch 5 and 6 moved to Qi's series from v3 onwards. * v1 patch 7 is superseded by patch 4 in Qi's series. Changes from v1 in the remaining patches: * Patch 1 only introduces __pagetable_ctor() as there is now a single generic pagetable_dtor(). * Patch 3 and 6: in arch/m68k/mm/motorola.c, free_pointer_table() can now unconditionally call pagetable_dtor() since it is the same for all levels. * Patch 6 just uses pagetable_dtor() instead of introducing pagetable_pgd_dtor(). * Added Dave Hansen's Acked-by to all patches. - Kevin [1] https://lore.kernel.org/linux-mm/cover.1735549103.git.zhengqi.arch@xxxxxxxxxxxxx/ --- Cc: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> Cc: Catalin Marinas <catalin.marinas@xxxxxxx> Cc: Dave Hansen <dave.hansen@xxxxxxxxxxxxxxx> Cc: Linus Walleij <linus.walleij@xxxxxxxxxx> Cc: Andy Lutomirski <luto@xxxxxxxxxx> Cc: Peter Zijlstra <peterz@xxxxxxxxxxxxx> Cc: "Mike Rapoport (IBM)" <rppt@xxxxxxxxxx> Cc: Ryan Roberts <ryan.roberts@xxxxxxx> Cc: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Cc: Will Deacon <will@xxxxxxxxxx> Cc: Matthew Wilcox <willy@xxxxxxxxxxxxx> Cc: Qi Zheng <zhengqi.arch@xxxxxxxxxxxxx> Cc: linux-alpha@xxxxxxxxxxxxxxx Cc: linux-arch@xxxxxxxxxxxxxxx Cc: linux-arm-kernel@xxxxxxxxxxxxxxxxxxx Cc: linux-csky@xxxxxxxxxxxxxxx Cc: linux-hexagon@xxxxxxxxxxxxxxx Cc: linux-kernel@xxxxxxxxxxxxxxx Cc: linux-m68k@xxxxxxxxxxxxxxxxxxxx Cc: linux-mips@xxxxxxxxxxxxxxx Cc: linux-openrisc@xxxxxxxxxxxxxxx Cc: linux-parisc@xxxxxxxxxxxxxxx Cc: linux-riscv@xxxxxxxxxxxxxxxxxxx Cc: linux-s390@xxxxxxxxxxxxxxx Cc: linux-snps-arc@xxxxxxxxxxxxxxxxxxx Cc: linux-um@xxxxxxxxxxxxxxxxxxx Cc: loongarch@xxxxxxxxxxxxxxx Cc: x86@xxxxxxxxxx --- Kevin Brodsky (6): mm: Move common part of pagetable_*_ctor to helper parisc: mm: Ensure pagetable_pmd_[cd]tor are called m68k: mm: Add calls to pagetable_pmd_[cd]tor ARM: mm: Rename PGD helpers asm-generic: pgalloc: Provide generic __pgd_{alloc,free} mm: Introduce ctor/dtor at PGD level
