I don't think anything arch-specific belongs in generic kernel header
paths.

If it feels strange to you, you can move it to arch/x86/include/asm/
There we put the arch-specific stuff.

Then you can do

#include <asm/perf/amd/iommu.h>

or so. I've moved it to arch/x86/events/amd/iommu.h already anyway.
