    x86, trampoline: Common infrastructure for low memory trampolines · 4822b7fc

    Common infrastructure for low memory trampolines.  This code installs
    the trampolines permanently in low memory very early.  It also permits
    multiple pieces of code to be used for this purpose.
    This code also introduces a standard infrastructure for computing
    symbol addresses in the trampoline code.
    The only change to the actual SMP trampolines themselves is that the
    64-bit trampoline has been made reusable -- the previous version would
    overwrite the code with a status variable; this moves the status
    variable to a separate location.
