  [POWERPC] fsl_soc: Make mac_addr const in fs_enet_of_init().
  [POWERPC] Don't use SLAB/SLUB for PTE pages
  [POWERPC] Spufs support for 64K LS mappings on 4K kernels
  [POWERPC] Add ability to 4K kernel to hash in 64K pages
  [POWERPC] Introduce address space "slices"
  [POWERPC] Small fixes & cleanups in segment page size demotion
  [POWERPC] iSeries: Make HVC_ISERIES the default
