Hello,
The aim of this series is to force the cache attribute of foreign and grant mappings to WB for HVM/PVH guests. This is required because those mappings will be likely be using unpopulated memory ranges in the p2m, and those are usually UC in the MTRR state. Having the guest set the correct MTRR attributes is also unlikely, because the number of MTRR ranges is finite.
