Ahh, I thought it had already passed your testing. So, you're saying that adding the include of slab.h to irq.h fixes the problem, and that removing the include of irq.h in malta-int.c is meaningless? This really is a maze of twisty little passages... ;-) (Btw, maybe you should submit the fixup patch to Andrew, I seem to only be adding to the confusion?)
