int
arm_drain_writebuf

arm_drain_writebuf
() will make sure that all the entries
in the processor write buffer are written out to memory.
Not all processors support this operation (currently only the SA110). Those processes that do not treat this function as a null-op.
arm_drain_writebuf
() will never fail so will always
return 0.
