ec847085fd - Use bus_dmamap_unload(), it is not optional. 
- The new allocator won't return coherent memory for any size > PAGE_SIZE,
so don't assume we have coherent memory, and explicitely use

6b0cb8bbef Write protect base page after superpage demotion so that it may repromote 
When clearing the modification status of the superpage, one of the
base pages produced during demotion should be marked as write disabled.
The intention is that subsequent write access may repromote.
In the current implementation this was done wrong as write permission was
granted instead of forbidden.

3b54dfb62d Unconditionally compile the __sync_* atomics support functions into compiler-rt 
for ARM.
This is quite ugly, because it has to work around a clang bug that does not
allow built-in functions to be defined, even when they're ones that are
expected to be built as part of a library.
