Eric,
What the reasons that you set MTRRs for one CPU two times.? amd_setup_mtrrs of amd_mtrr.c call x86_setup_mtrrs...
This is just the fixed mtrrs. The code should be refined further, but this code properly sets the RD_MEM and WR_MEM bits in the fixed mtrrs.
Given how the code is currently factored this was the easiest way to code it cleanly. I expect to revisit this when looking at overlapping mtrr support.
