[Cbe-oss-dev] [PATCH] libspe2: Fix _base_spe_count_physical_cpus

[malc]

This patch fixes the counting of physical cpus, and thus the counting
of spus per cpu.

Currently - we count the number of dirent entries in
/sys/devices/system/cpu/ starting at -2 (to ignore . and ..)
At some point additional entries were added to this chunk of sysfs -

ps3-64ul ~ # ls /sys/devices/system/cpu/
cpu0  cpu1  online  possible  present

And so the number of CPUs in the system is reported incorrectly - it
then follows that the number of spus is also reported incorrectly.

The following patch makes the counting of cpu's somewhat more bullet proof.
