  • Add some documentation for the 64-bit syscall ABI, which doesn't seem
    to be documented elsewhere.

    This attempts to document existing practice. The only small discrepancy
    is glibc clobbers not quite matching the kernel (e.g., xer, some
    vsyscalls trash cr1 whereas glibc only clobbers cr0). These will be
    resolved after this document is merged.
