[Xen-devel] mmio_decode()



Could anyone enlighten me why this function decodes arbitrary opcodes?
I.e. 0x20...0x23 are all getting decoded, but only 0x00 (and not
0x01...0x03) and only 0x2B (and not 0x2A). I guess this is based on
observed instructions used for mmio, but - this doesn't make sense! That
way, we'll never get to a point where arbitrary OSes (or other
environments) can get emulated.

(To make things odd, I'm complaining about this while the absence of
a decode for 0x00 actually helped pointing out another problem that
I'm in the process of trying to address: Newer isolinux runs partly in
non-flat protected mode, which apparently isn't generally being
considered a supported environment).
