Again, there may not *be* an MPS table, and if there is but the
interrupt links are programmable, the MPS table may have very little
in common with the state of the machine in ACPI mode.

I don't understand why scribbling on upstream Linux in the name
of science fiction makes any sense.

I just don't get it.
