From: Jean-Christian de Rivaz <jc at eclis.ch>

According to Russell King:
In any case, unless you have a Marvell platform, you should have this
disabled - it provides a performance boost for Marvell platforms, but
degrades performance everywhere else.  Please ensure that you disable
CONFIG_UACCESS_WITH_MEMCPY.
