[v2,0/4] Update DF/SMN access and k10temp for AMD F17h M30h

Message

Updates the data fabric/system management network code needed to get
k10temp working for M30h.  Since there are now processors which have
multiple roots per DF/SMN interface, there needs to some logic which
skips N-1 root complexes per DF/SMN interface.  This is because the root
complexes per interface are redundant (as far as DF/SMN goes).  These
changes shouldn't effect past processors and, for F17h M0Xh, the
mappings stay the same.

v1 -> v2:
  * patch 3 & 4: add M30_DF_F3 straight to pci_ids.h to reduce churn
  * patch 2:
    - update commit msg and comment to explain root selection further
    - move return if !misc_count under where misc_count is calculated

Brian Woods (4):
  k10temp: x86/amd_nb: consolidate shared device IDs
  x86/amd_nb: add support for newer PCI topologies
  x86/amd_nb: add PCI device IDs for F17h M30h
  hwmon: k10temp: add support for AMD F17h M30h CPUs
