//#ifdef CONFIG_ARCH_ARM
/* When seL4 creates a new frame object it zeroes the associated memory
* through a cached kernel mapping. If we are configuring a cached
* mapping for the target, standard coherence protocols ensure
* everything works as expected. However, if we are configuring an
* uncached mapping for the target, the dirty zero data cached from the
* kernel's mapping is likely flushed to memory at some time in the
* future causing an unpleasant surprise for the target whose own
* uncached writes are mysteriously overwritten. To prevent this, we
* unify the mapping here, flushing the cached data from the kernel's
* mapping.
