Daniel Eklöf	62ca06eccb	module/cpu: don’t use core ID from /proc/stat as array index ... /proc/stat lists CPU usage, in the form: cpu ... cpu0 ... cpu1 ... ... cpuN ... where the first line is a summary line. We’ve been using the CPU numbers from /proc/stat to index into our internal stats array. This doesn’t work on systems where the core IDs aren’t consecutive. Examples of such systems are SMT systems with SMT disabled. Here, /proc/stat may look like this instead: cpu ... cpu0 ... cpu2 ... cpu4 ... ... With this patch, we ignore the CPU ID from /proc/stat. Instead, we use a simple counter that is incremented for each (valid) cpu line found in /proc/stat. To protect against corrupt /proc/stat content, stop parsing /proc/stat if the number of parsed CPU lines exceed what we consider to the be total number of CPUs in the system.
