Pull x86 platform changes from Ingo Molnar:

 - Support for the Technologic Systems TS-5500 platform, by Vivien
   Didelot

 - Improved NUMA support on AMD systems:

   Add support for federated systems where multiple memory controllers
   can exist and see each other over multiple PCI domains.  This
   basically means that AMD node ids can be more than 8 now and the code
   handling this is taught to incorporate PCI domain into those IDs.

 - Support for the Goldfish virtual Android emulator, by Jun Nakajima,
   Intel, Google, et al.

 - Misc fixlets.
