[PATCH V3 01/11] cris: move usec/nsec conversion to do_slow_gettimeoffset

From: Stephen Warren
Date: Mon Nov 19 2012 - 13:37:28 EST


From: Stephen Warren <swarren@xxxxxxxxxx>

Move usec to nsec conversion from arch_gettimeoffset() to
do_slow_gettimeoffset(); in a future patch, do_slow_gettimeoffset()
will be used directly as the implementation of arch_gettimeoffset(),
so needs to perform all required calculations.
