So what's up?
I tested the function on Hygon Dhyana platforms with the latest BIOS,
found that this problem is indeed

OK, agree on it.

Hygon CPU have a special magic MSR way to force WB for memory >4GB,
and also support TOP_MEM2. Therefore, it is necessary to add Hygon
support in amd_special_default_mtrr().
The MtrrFixDramModEn bit on Hygon platform should also be set to 1
during BIOS initialization of the fixed MTRRs, then
