    Subject[PATCH 0/8] convert remaining archs to use vm_unmapped_area()
    Date
    This is a resend of my "finish the mission" patch series. I need arch
    maintainers to approve so I can push this to andrew's -mm tree.

    These patches, which apply on top of v3.8-rc kernels, are to complete the
    VMA gap finding code I introduced (following Rik's initial proposal) in
    v3.8-rc1.

    First 5 patches introduce the use of vm_unmapped_area() to replace brute
    force searches on parisc, alpha, frv and ia64 architectures (all relatively
    trivial uses of the vm_unmapped_area() infrastructure)

    Next 2 patches do the same as above for the powerpc architecture. This
    change is not as trivial as for the other architectures, because we
    need to account for each address space slice potentially having a
    different page size.

    The last patch removes the free_area_cache, which was used by all the
    brute force searches before they got converted to the
    vm_unmapped_area() infrastructure.

    I did some basic testing on x86 and powerpc; however the first 5 (simpler)
    patches for parisc, alpha, frv and ia64 architectures are untested.

    Michel Lespinasse (8):
    mm: use vm_unmapped_area() on parisc architecture
    mm: use vm_unmapped_area() on alpha architecture
    mm: use vm_unmapped_area() on frv architecture
    mm: use vm_unmapped_area() on ia64 architecture
    mm: use vm_unmapped_area() in hugetlbfs on ia64 architecture
    mm: remove free_area_cache use in powerpc architecture
    mm: use vm_unmapped_area() on powerpc architecture
    mm: remove free_area_cache
