the exact same address, and likewise STs to the exact same address.
Ordinarily this would make absolutely no sense whatsoever, except
-that Power ISA has cache-inhibited LD/STs, for accessing memory-mapped
+that Power ISA has cache-inhibited LD/STs (Power ISA v.1, Book III,
+1.6.1, p1033), for accessing memory-mapped
peripherals and other crucial uses. Thus, *despite not being a mapreduce mode*,
zero-immediates cause multiple hits on the same element.
