    Hello Andi,

    The following emails contain the patches to convert x86-64 to store current
    in r10 (also at http://www.kvack.org/~bcrl/patches/v2.6.15-rc3/). This
    provides a significant amount of code savings (~43KB) over the current
    use of the per cpu data area. I also tested using r15, but that generated
    code that was larger than that generated with r10. This code seems to be
    working well for me now (it stands up to 32 and 64 bit processes and ptrace
    users) and would be a good candidate for further exposure.
