Weird.  This is just a C variable declared in i386/shared/irq/irq.c.  I
went looking for it expecting to find some assembly code. :(

it is used like this in i386ex/start/start.S

start.S:      movw    $0xFFFB, SYM(i8259s_cache) /* set up same values in cache */

I am heading out the door.  Any other ideas what could have tripped this?

Should there be an extern of some sort to tell gas it is an extern data32
entity?
