Subject: [PATCH 20/21] 2.6.19 perfmon2 : new x86_64 files

This patch contains the new x86_64 files.

The files are as follows:


arch/x86_64/perfmon/Kconfig:
	- add menuconfig options

arch/x86_64/perfmon/Makefile:
	- makefile for arch specific files

arch/x86_64/perfmon/perfmon_k8.c:
	- PMU description for Opteron/Althon64 PMU for both 32 and 64-bit modes

arch/x86_64/perfmon/perfmon_core.c:
	- PMU description for Intel Core-bsaed processors

include/asm-x86_64/perfmon.h:
	- architecture specific header definitions
