Here are some pretty straightforward updates, but ultimately wonder if we cannot make the call the same for all archs; which is where we seem to be headed _anyway_, more of this in Patch 3 which updates x86. Patch 1 is just one a snuck in while looking at arch code. Only tested on the x86 bits. Thanks!
