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?)
Thanks, Mike
