755c959170 Remove OF_instance_to_package() hack for FDT and replace with use of the 
generic OF_xref_phandle() API universally. Also replace some related
explicit uses of fdt32_to_cpu() with OF_getencprop() calls.

63e950fe80 - 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
bus_dmamap_sync().

deb179bb4c The pmap function pmap_clear_reference() is no longer used. Remove it. 
pmap_clear_reference() has had exactly one caller in the kernel for
several years, more precisely, since FreeBSD 8.  Now, that call no
longer exists.

8b78ad43bc 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.

e1c0c6422a Unconditionally compile the __sync_* atomics support functions into compiler-rt

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.
