    mm: kill vma flag VM_RESERVED and mm->reserved_vm counter

    A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA,
    currently it lost original meaning but still has some effects:

     | effect                 | alternative flags
    -+------------------------+---------------------------------------------
    1| account as reserved_vm | VM_IO
    2| skip in core dump      | VM_IO, VM_DONTDUMP
    3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
    4| do not mlock           | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP

    This patch removes reserved_vm counter from mm_struct.  Seems like nobody
    cares about it, it does not exported into userspace directly, it only
    reduces total_vm showed in proc.

    Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP.

    remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP.
    remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.
