NAME
     arm_drain_writebuf -- drains the CPU write buffer

LIBRARY
     ARM Architecture Library (libarm, -larm)

SYNOPSIS
     #include <machine/sysarch.h>

     int
     arm_drain_writebuf();

DESCRIPTION
     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.
