  x86, cpa: make the kernel physical mapping initialization a two pass sequence, fix
  x86, pat: cleanups
  x86: fix pagetable init 64-bit breakage
  x86: track memtype for RAM in page struct
  x86, cpa: srlz cpa(), global flush tlb after splitting big page and before doing cpa
  x86, cpa: remove cpa pool code
  x86, cpa: no need to check alias for __set_pages_p/__set_pages_np
  x86, cpa: dont use large pages for kernel identity mapping with DEBUG_PAGEALLOC
  x86, cpa: make the kernel physical mapping initialization a two pass sequence
  x86, cpa: remove USER permission from the very early identity mapping attribute
  x86, cpa: rename PTE attribute macros for kernel direct mapping in early boot
  x86: make sure the CPA test code's use of _PAGE_UNUSED1 is obvious
  linux-next: fix x86 tree build failure
  x86: have set_memory_array_{uc,wb} coalesce memtypes, fix
  agp: enable optimized agp_alloc_pages methods
  x86: have set_memory_array_{uc,wb} coalesce memtypes.
  x86: {reverve,free}_memtype() take a physical address
  x86: fix pageattr-test
  agp: add agp_generic_destroy_pages()
