[PATCH] Fix get_nodes() mask miscalculation
It appears there is a nodemask miscalculation in the get_nodes() function
in mm/mempolicy.c. This bug has two effects:
1. It is impossible to specify a length 1 nodemask.
2. It is impossible to specify a nodemask containing the last node.
The following patch has been confirmed to solve both problems.
