This is a revised patch to merge asm-ppc*/hardirq.h. It removes some unnecessary #includes, but then requires the addition of #include <asm/irq.h> in PPC32's hw_irq.h much like ppc64 already does. Furthermore, several unnecessary #includes were removed from some ppc32 boards in order to break resulting bad #include cycles. Builds pSeries_defconfig and all ppc32 platforms except the already b0rken bseip.
