There is good old tradition: every year somebody submit patches for extending vma->vm_flags upto 64-bits, because there no free bits left on 32-bit systems. previous attempts: https://lkml.org/lkml/2011/4/12/24 (KOSAKI Motohiro) https://lkml.org/lkml/2010/4/27/23 (Benjamin Herrenschmidt) https://lkml.org/lkml/2009/10/1/202 (Hugh Dickins) Here already exist special type for this: vm_flags_t, but not all code uses it. So, before switching vm_flags_t from unsinged long to u64 we must spread vm_flags_t everywhere and fix all possible type-casting problems. There is no functional changes in this patch set, it only prepares code for vma->vm_flags converting. --- Konstantin Khlebnikov (16): mm: introduce NR_VMA_FLAGS mm: use vm_flags_t for vma flags mm/shmem: use vm_flags_t for vma flags mm/nommu: use vm_flags_t for vma flags mm/drivers: use vm_flags_t for vma flags mm/x86: use vm_flags_t for vma flags mm/arm: use vm_flags_t for vma flags mm/unicore32: use vm_flags_t for vma flags mm/ia64: use vm_flags_t for vma flags mm/powerpc: use vm_flags_t for vma flags mm/s390: use vm_flags_t for vma flags mm/mips: use vm_flags_t for vma flags mm/parisc: use vm_flags_t for vma flags mm/score: use vm_flags_t for vma flags mm: cast vm_flags_t to u64 before printing mm: vm_flags_t strict type checking arch/arm/include/asm/cacheflush.h | 5 - arch/arm/kernel/asm-offsets.c | 6 + arch/arm/mm/fault.c | 2 arch/ia64/mm/fault.c | 9 + arch/mips/mm/c-r3k.c | 2 arch/mips/mm/c-r4k.c | 6 - arch/mips/mm/c-tx39.c | 2 arch/parisc/mm/fault.c | 4 - arch/powerpc/include/asm/mman.h | 2 arch/s390/mm/fault.c | 8 + arch/score/mm/cache.c | 6 - arch/sh/mm/tlbflush_64.c | 2 arch/unicore32/kernel/asm-offsets.c | 6 + arch/unicore32/mm/fault.c | 2 arch/x86/mm/hugetlbpage.c | 4 - drivers/char/mem.c | 2 drivers/infiniband/hw/ipath/ipath_file_ops.c | 6 + drivers/infiniband/hw/qib/qib_file_ops.c | 6 + drivers/media/video/omap3isp/ispqueue.h | 2 drivers/staging/android/ashmem.c | 2 drivers/staging/android/binder.c | 15 +- drivers/staging/tidspbridge/core/tiomap3430.c | 13 +- drivers/staging/tidspbridge/rmgr/drv_interface.c | 4 - fs/binfmt_elf.c | 2 fs/binfmt_elf_fdpic.c | 24 ++- fs/exec.c | 2 fs/proc/nommu.c | 3 fs/proc/task_nommu.c | 14 +- include/linux/backing-dev.h | 7 - include/linux/huge_mm.h | 4 - include/linux/ksm.h | 8 + include/linux/mm.h | 163 +++++++++++++++------- include/linux/mm_types.h | 11 + include/linux/mman.h | 4 - include/linux/rmap.h | 8 + include/linux/shmem_fs.h | 5 - kernel/bounds.c | 2 kernel/events/core.c | 4 - kernel/fork.c | 2 kernel/sys.c | 4 - mm/backing-dev.c | 4 + mm/huge_memory.c | 2 mm/ksm.c | 4 - mm/madvise.c | 2 mm/memory.c | 9 + mm/mlock.c | 2 mm/mmap.c | 36 ++--- mm/mprotect.c | 9 + mm/mremap.c | 2 mm/nommu.c | 19 +-- mm/rmap.c | 16 +- mm/shmem.c | 54 ++++--- mm/vmscan.c | 4 - 53 files changed, 322 insertions(+), 224 deletions(-) -- Signature -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
