Please please don't get into the habit of calling it ARM32 and ARM64, 
you're just sowing confusion; there are good reasons why those names 
weren't adopted (some technical, some not) and I'm not about to rehash 
them all now.  AArch32 and AArch64 aren't that much harder to type and 
they are completely unambiguous.

If nothing else, remember that there were arm3 and arm6 chips at one 
time, so we have patterns that match arm3* and arm6* to match those CPUs 
(because people keep insisting on adding miscellaneous junk at the end 
of the CPU field).  At all costs we need to avoid getting false matches 
in here, or chaos will ensue.

The architecture overall is ARM, the operating states within it are 
AArch32 and AArch64.  There is no ARM32 and there is no ARM64.
