    I guess this may be the only patch needed so far. x86_64 doesn't use a
    RWSEM_XCHGADD_ALGORITHM, and as for the other archs:

    alpha and ia64 - doesn't have PREEPMT_RT yet.

    arm, cris, frv, h8300, m32r, parsic don't seem to implement the XCHGADD.

    But I see that powerpc will need a fix, but I'll let others who actually
    have the boards to fix them. ;-)

    As for what I own: x86_64 and i386, the patches I sent are sufficient.

    If anyone would like to give me a special board (to keep), I'll gladly
    make sure that Ingo's -RT kernel runs on it.
