    SubjectPossible shared mapping bug in 2.4.23 (at least MIPS/Sparc)
    The current MIPS 2.4 kernel (from CVS) currently allows fixed shared
    mappings to violate D-cache aliasing constraints.

    The check for illegal fixed mappings is done in
    arch_get_unmapped_area(), but these mappings are granted in
    get_unmapped_area() and arch_get_unmapped_area() is never called.

    A quick look at sparc and sparc64 seem to show the same problem.
