mtd_cpl question

[Chuck Tuffli <chuck_tuffli@xxxxxxxxxxx>]

sys/i386/include/thread.h defines a structure md_thread which contains
a variable called mtd_cpl that I think is a mask of the current
software and hardware interrupts. Is the size of this variable tied to
some x86 architecture constraint or can it be arbitrarily increased to
something bigger? For instance

    unsigned int	mtd_cpl[8];

so that the mask can represent all 256 vectors defined in IA.
