-Only count directories that match /sys/devices/system/cpu/cpu[0-9]+ as
-CPUs.  Previously any directory that started with cpu was counted which
-caused cpufreq and cpuidle to be counted as CPUs.

-Special interrupt counts line NMI may start with a space
-
-The kernel determines the maximum number of possible IRQs and pads the
-first field of /proc/interrupts appropriately.  With four or more digits
-of precession the special interrupt counts all start with a space
-instead of a letter.  This caused the special interrupt counts to be
-counted on my system and that caused the cpunr count to be off when it
-reached the ERR and MIS lines forcing a CPU rescan.
