      Pull x86 mm changes from Peter Anvin:
       "This is a huge set of several partly interrelated (and concurrently
        developed) changes, which is why the branch history is messier than
        one would like.
      
        The *really* big items are two humonguous patchsets mostly developed
        by Yinghai Lu at my request, which completely revamps the way we
        create initial page tables.  In particular, rather than estimating how
        much memory we will need for page tables and then build them into that
        memory -- a calculation that has shown to be incredibly fragile -- we
        now build them (on 64 bits) with the aid of a "pseudo-linear mode" --
        a #PF handler which creates temporary page tables on demand.
      
        This has several advantages:
      
        1. It makes it much easier to support things that need access to data
           very early (a followon patchset uses this to load microcode way
           early in the kernel startup).
      
        2. It allows the kernel and all the kernel data objects to be invoked
           from above the 4 GB limit.  This allows kdump to work on very large
           systems.
      
        3. It greatly reduces the difference between Xen and native (Xen's
           equivalent of the #PF handler are the temporary page tables created
           by the domain builder), eliminating a bunch of fragile hooks.
      
        The patch series also gets us a bit closer to W^X.
      
        Additional work in this pull is the 64-bit get_user() work which you
        were also involved with, and a bunch of cleanups/speedups to
        __phys_addr()/__pa()."

      Pull x86 cpu updates from Peter Anvin:
       "This is a corrected attempt at the x86/cpu branch, this time with the
        fixes in that makes it not break on KVM (current or past), or any
        other virtualizer which traps on this configuration.
      
        Again, the biggest change here is enabling the WC+ memory type on AMD
        processors, if the BIOS doesn't."

      Linus Torvalds authored
      Pull s390 update from Martin Schwidefsky:
       "The most prominent change in this patch set is the software dirty bit
        patch for s390.  It removes __HAVE_ARCH_PAGE_TEST_AND_CLEAR_DIRTY and
        the page_test_and_clear_dirty primitive which makes the common memory
        management code a bit less obscure.
      
        Heiko fixed most of the PCI related fallout, more often than not
        missing GENERIC_HARDIRQS dependencies.  Notable is one of the 3270
        patches which adds an export to tty_io to be able to resize a tty.
      
        The rest is the usual bunch of cleanups and bug fixes."
