From 945feb174b14e7098cc7ecf0cf4768d35bc52f9c Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Thu, 17 Apr 2008 14:35:01 +1000 Subject: [POWERPC] irqtrace support for 64-bit powerpc This adds the low level irq tracing hooks to the powerpc architecture needed to enable full lockdep functionality. This is partly based on Johannes Berg's initial version. I removed the asm trampoline that isn't needed (thus improving performance) and modified all sorts of bits and pieces, reworking most of the assembly, etc...
