Commit 47d68979cc96 ("md/raid0: fix bug with chunksize not a power of 2.") introduced in v4.1 development has been picked by stable trees, and is causing issues (see https://bugzilla.kernel.org/show_bug.cgi?id=98501).

This commit has been dropped from Vivid and Utopic when pulling the changes from stable trees 3.19.7 and 3.16.7-ckt11 respectively (bug #1454699 and bug #1454202).
