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.

ERRORS
     arm_drain_writebuf() will never fail so will always return 0.
