576 Set affinity mask of trace reading thread according to the policy defined by 'mode' value:
578 - node - thread affinity mask is set to NUMA node cpu mask of the processed mmap buffer
579 - cpu - thread affinity mask is set to cpu of the processed mmap buffer
797 define CPUs to be monitored by a thread and affinity mask of that thread
800 <cpus mask 1>/<affinity mask 1>:<cpus mask 2>/<affinity mask 2>:...
802 CPUs or affinity masks must not overlap with other corresponding masks.
811 the first thread monitors CPUs 0 and 2-4 with the affinity mask 2-4,
812 the second monitors CPUs 1 and 5-7 with the affinity mask 5-7.
