oprofile, x86: Check IBS capability bits 1 and 2 There are IBS CPUID feature flags in CPUID Fn8000_001B to detect if the cpu supports IBS fetch sampling (FetchSam) and/or IBS execution sampling (OpSam). This patch adds checks if the both features are available. Spec: http://support.amd.com/us/Processor_TechDocs/31116.pdf Signed-off-by: Robert Richter <robert.richter@amd.com>
