For performance analysis, it is often interesting to know which physical SPE a thread is currently running on, and, more importantly, if it is running at all. This patch adds a simple attribute to each SPU directory with that information. The attribute is read-only and called 'phys-id'. It contains an ascii string with the number of the physical SPU (e.g. "0x5"), or alternatively the string "0xffffffff" (32 bit -1) when it is not running at all at the time that the file is read.
