Hi all, This series introduces aarch_mmap_hint() to handle allocating VA space for the hint address. Patches 1-16 introduce this new helper and Patch 17 uses it to fix the issue of mmap hint being ignored in some cases due to THP alignment [1] [1] https://lore.kernel.org/r/20241118214650.3667577-1-kaleshsingh@xxxxxxxxxx/ Thanks, Kalesh Kalesh Singh (17): mm: Introduce generic_mmap_hint() mm: x86: Introduce arch_mmap_hint() mm: arm: Introduce arch_mmap_hint() mm: alpha: Introduce arch_mmap_hint() mm: arc: Use generic_mmap_hint() mm: csky: Introduce arch_mmap_hint() mm: loongarch: Introduce arch_mmap_hint() mm: mips: Introduce arch_align_mmap_hint() mm: parisc: Introduce arch_align_mmap_hint() mm: s390: Introduce arch_mmap_hint() mm: sh: Introduce arch_mmap_hint() mm: sparc32: Introduce arch_mmap_hint() mm: sparc64: Introduce arch_mmap_hint() mm: xtensa: Introduce arch_mmap_hint() mm: powerpc: Introduce arch_mmap_hint() mm: Fallback to generic_mmap_hint() mm: Respect mmap hint before THP alignment if allocation is possible arch/alpha/include/asm/pgtable.h | 1 + arch/alpha/kernel/osf_sys.c | 29 ++++++++++-- arch/arc/mm/mmap.c | 12 ++--- arch/arm/include/asm/pgtable.h | 1 + arch/arm/mm/mmap.c | 54 ++++++++++++--------- arch/csky/abiv1/inc/abi/pgtable-bits.h | 1 + arch/csky/abiv1/mmap.c | 38 ++++++++++----- arch/loongarch/include/asm/pgtable.h | 1 + arch/loongarch/mm/mmap.c | 40 ++++++++++------ arch/mips/include/asm/pgtable.h | 1 + arch/mips/mm/mmap.c | 39 +++++++++------ arch/parisc/include/asm/pgtable.h | 1 + arch/parisc/kernel/sys_parisc.c | 37 ++++++++++----- arch/powerpc/include/asm/book3s/64/slice.h | 1 + arch/powerpc/mm/book3s64/slice.c | 31 ++++++++++++ arch/s390/include/asm/pgtable.h | 1 + arch/s390/mm/mmap.c | 32 ++++++------- arch/sh/include/asm/pgtable.h | 1 + arch/sh/mm/mmap.c | 48 ++++++++++--------- arch/sparc/include/asm/pgtable_32.h | 1 + arch/sparc/include/asm/pgtable_64.h | 1 + arch/sparc/kernel/sys_sparc_32.c | 21 +++++++-- arch/sparc/kernel/sys_sparc_64.c | 47 +++++++++++++----- arch/x86/include/asm/pgtable_64.h | 1 + arch/x86/kernel/sys_x86_64.c | 49 ++++++++++--------- arch/xtensa/include/asm/pgtable.h | 1 + arch/xtensa/kernel/syscall.c | 26 +++++++++- include/linux/sched/mm.h | 8 ++++ mm/huge_memory.c | 15 +++--- mm/mmap.c | 55 ++++++++++++++-------- 30 files changed, 401 insertions(+), 193 deletions(-) -- 2.47.0.338.g60cca15819-goog
