    Subject[PATCH 00/16] mm: prepare for converting vm->vm_flags to 64-bit
    From
    Date
    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.

    mm: introduce NR_VMA_FLAGS
    mm: use vm_flags_t for vma flags
    mm/shmem: use vm_flags_t for vma flags
