[PATCH] python-linux-procfs: fix parse_affinity for CPU numbers greater than 31

[John Kacur]

From: Jozef Bacik <***@redhat.com>

The function parse_affinity reports wrong results for CPU numbers
greater than 31.

The problem is caused by the function bitmastlist which parse_affinity
calls. The fix treats the inpput line as a long hexbitmask instead of an
array in order to produce correct results
