3.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Matthias Schiffer <mschiffer@xxxxxxxxxxxxxxxxxxxx> commit 906b1c394d0906a154fbdc904ca506bceb515756 upstream. The bitmask used for the prefix mangling was being calculated incorrectly, leading to the wrong part of the address being replaced when the prefix length wasn't a multiple of 32.
