Hi all, The theme of this set is decoupling the "AMD node" concept from the legacy northbridge support. Additionally, AMD System Management Network (SMN) access code is decoupled and expanded too. Patches 1-3 begin reducing the scope of AMD_NB. Patches 4-9 begin moving generic AMD node support out of AMD_NB. Patches 10-13 move SMN support out of AMD_NB and do some refactoring. Patch 14 has HSMP reuse SMN functionality. Patches 15-16 address userspace access to SMN. I say "begin" above because there is more to do here. Ultimately, AMD_NB should only be needed for code used on legacy systems with northbridges. Also, any and all SMN users in the kernel need to be updated to use the central SMN code. Local solutions should be avoided.
