    Thanks. FWIW, changes since the last posting:
    * untested conversion for cris added [me]
    * conversion for mips added [Ralf has done execve side, I've added
    kernel_thread() one]
    * conversion for parisc added [aka "Al has generated broken patches,
    jejb has tested and fixed that crap"]
    * arm64 conversion added [Catalin Marinas]

    IOW, right now we have
    * alpha, arm, arm64, c6x, m68k, mips, parisc, powerpc, s390, sparc,
    um, x86 - apparently over and done with (IOW, all old architectures except for
    itanic are converted by now)
    * avr32, blackfin, hexagon, h8300, ia64, m32r, microblaze, openrisc,
    score, sh, tile, unicore32, xtensa - need to be done
    * cris, frv, mn10300 - need to be tested (and very likely will need
    fixing)
