copyRegs and copyMiscRegs were moved to utility.hh and utility.cc.

c913c64be2 ARM: Add a memory_barrier function to the "comm page". 
This function doesn't actually provide a memory barrier (I don't think they're
implemented) and instead just returns.

3ff1e922c2 ARM: Add a cmpxchg implementation to the "comm page". 
This implementation does what it's supposed to (I think), but it's not atomic
and doesn't have memory barriers like the kernel's version.
