From 3e57615bb5a8b6208627049884ee441f6d05905e Mon Sep 17 00:00:00 2001 From: "linuxppc@jdl.com" Date: Mon, 19 Sep 2005 09:32:07 -0500 Subject: [PATCH] powerpc: Revised merge asm-ppc*/hardirq.h This is a revised patch to merge asm-ppc*/hardirq.h. It removes some unnecessary #includes, but then requires the addition of #include 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.
