*	[PATCH] x86: i386/x86-64 Add nmi watchdog support for new Intel CPUs	Venkatesh Pallipadi	2006-09-26
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	AK: This redoes the changes I temporarily reverted. Intel now has support for Architectural Performance Monitoring Counters ( Refer to IA-32 Intel Architecture Software Developer's Manual http://www.intel.com/design/pentium4/manuals/253669.htm ). This feature is present starting from Intel Core Duo and Intel Core Solo processors. What this means is, the performance monitoring counters and some performance monitoring events are now defined in an architectural way (using cpuid). And there will be no need to check for family/model etc for these architectural events. Below is the patch to use this performance counters in nmi watchdog driver. Patch handles both i386 and x86-64 kernels. Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Andi Kleen <ak@suse.de>
