From 193c81b979adbc4a540bf89e75b9039fae75bf82 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sat, 31 Jan 2009 02:23:27 +0100 Subject: [PATCH] x86, irq: add LOCAL_PERF_VECTOR Add a slot for the performance monitoring interrupt. Not yet used by any subsystem - but the hardware has it. (This eases integration with performance monitoring code.)
