Merge branch 'x86-platform-for-linus' of git://git.kernel.org/pub/scm…

…/linux/kernel/git/tip/tip

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.

* 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86: Add TS-5500 platform support
  x86/srat: Simplify memory affinity init error handling
  x86/apb/timer: Remove unnecessary "if"
  goldfish: platform device for x86
  amd64_edac: Fix type usage in NB IDs and memory ranges
  amd64_edac: Fix PCI function lookup
  x86, AMD, NB: Use u16 for northbridge IDs in amd_get_nb_id
  x86, AMD, NB: Add multi-domain support
