    x86, setup: "glove box" BIOS calls -- infrastructure · 7a734e7d

    Impact: new interfaces (not yet used)
    
    For all the platforms out there, there is an infinite number of buggy
    BIOSes.  This adds infrastructure to treat BIOS interrupts more like
    toxic waste and "glove box" them -- we switch out the register set,
    perform the BIOS interrupt, and then restore the previous state.
