No need to emit them at VM flush as we no longer use

Based on Dmitries work, but splitting the code into page
directory and page table handling makes it far more
readable and (hopefully) more reliable.

Allocations of page tables are made from the SA on demand,
that should still work fine since all page tables are of
the same size.

Also using the fact that allocations from the SA are mostly
continuously (except for end of buffer wraps and under very
high memory pressure) to group updates send to the chipset
specific code into larger chunks.

Pull media updates from Mauro Carvalho Chehab:
 "The first part of the media updates for Kernel 3.7.

  This series contain:

   - A major tree renaming patch series: now, drivers are organized
     internally by their used bus, instead of by V4L2 and/or DVB API,
     providing a cleaner driver location for hybrid drivers that
     implement both APIs, and allowing to cleanup the Kconfig items and
     make them more intuitive for the end user;

   - Media Kernel developers are typically very lazy with their duties
     of keeping the MAINTAINERS entries for their drivers updated.  As
     now the tree is more organized, we're doing an effort to add/update
     those entries for the drivers that aren't currently orphan;

   - Several DVB USB drivers got moved to a new DVB USB v2 core; the new
     core fixes several bugs (as the existing one that got bitroted).
     Now, suspend/resume finally started to work fine (at least with
     some devices - we should expect more work with regards to it);

   - added multistream support for DVB-T2, and unified the API for
     DVB-S2 and ISDB-S.  Backward binary support is preserved;

   - as usual, a few new drivers, some V4L2 core improvements and lots
     of drivers improvements and fixes.

  There are some points to notice on this series:

   1) you should expect a trivial merge conflict on your tree, with the
      removal of Documentation/feature-removal-schedule.txt: this series
      would be adding two additional entries there.  I opted to not
      rebase it due to this recent change;

   2) With regards to the PCTV 520e udev-related breakage, I opted to
      fix it in a way that the patches can be backported to 3.5 even
      without your firmware fix patch.  This way, Greg doesn't need to
      rush backporting your patch (as there are still the firmware cache
      and firmware path customization issues to be addressed there).

      I'll send later a patch (likely after the end of the merge window)
      reverting the rest of the DRX-K async firmware request, fully
      restoring its original behaviour to allow media drivers to
      initialize everything serialized as before for 3.7 and upper.

   3) I'm planning to work on this weekend to test the DMABUF patches
      for V4L2.  The patches are on my queue for several Kernel cycles,
      but, up to now, there is/was no way to test the series locally.

      I have some concerns about this particular changeset with regards
      to security issues, and with regards to the replacement of the old
      VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to
      GPU drivers change.  The Overlay API allows direct PCI2PCI
      transfers from a media capture card into the GPU framebuffer, but
      its API is crappy.  Also, the only existing X11 driver that
      implements it requires a XV extension that is not available
      anymore on modern drivers.  The DMABUF can do the same thing, but
      with it is promising to be a properly-designed API.  If I can
      successfully test this series and be happy with it, I should be
      asking you to pull them next week."

Pull UAPI disintegration fixes from David Howells:
 "There are three main parts:

 (1) I found I needed some more fixups in the wake of testing Arm64
     (some asm/unistd.h files had weird guards that caused problems -
     mostly in arches for which I don't have a compiler) and some
     __KERNEL__ splitting needed to take place in Arm64.

 (2) I found that c6x was missing some __KERNEL__ guards in its
     asm/signal.h.  Mark Salter pointed me at a tree with a patch to
     remove that file entirely and use the asm-generic variant instead.

 (3) Lastly, m68k turned out to have a header installation problem due
     to it lacking a kvm_para.h file.

     The conditional installation bits for linux/kvm_para.h, linux/kvm.h
     and linux/a.out.h weren't very well specified - and didn't work if
     an arch didn't have the asm/ version of that file, but there *was*
     an asm-generic/ version.

     It seems the "ifneq $((wildcard ...),)" for each of those three
     headers in include/kernel/Kbuild is invoked twice during header
     installation, and the second time it matches on the just installed
     asm-generic/kvm_para.h file and thus incorrectly installs
     linux/kvm_para.h as well.

     Most arches actually have an asm/kvm_para.h, so this wasn't
     detectable in those."

Pull ADM Xen support from Konrad Rzeszutek Wilk:

  Features:
   * Allow a Linux guest to boot as initial domain and as normal guests
     on Xen on ARM (specifically ARMv7 with virtualized extensions).  PV
     console, block and network frontend/backends are working.
  Bug-fixes:
   * Fix compile linux-next fallout.
   * Fix PVHVM bootup crashing.

  The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports
  ARMv7 platforms.

  The goal in implementing this architecture is to exploit the hardware
  as much as possible.  That means use as little as possible of PV
  operations (so no PV MMU) - and use existing PV drivers for I/Os
  (network, block, console, etc).  This is similar to how PVHVM guests
  operate in X86 platform nowadays - except that on ARM there is no need
  for QEMU.  The end result is that we share a lot of the generic Xen
  drivers and infrastructure.

  Details on how to compile/boot/etc are available at this Wiki:

Merge misc patches from Andrew Morton:
 "The MM tree is rather stuck while I wait to find out what the heck is
  happening with sched/numa.  Probably I'll need to route around all the
  code which was added to -next, sigh.

  So this is "everything else", or at least most of it - other small
  bits are still awaiting resolutions of various kinds."

Fix the warning:

  WARNING: vmlinux.o(.text+0x14cfd8): Section mismatch in reference from the variable compressed_formats to the function .init.text:gunzip()
  The function compressed_formats() references
  the function __init gunzip().
  etc..

Within decompress.c, compressed_formats[] needs 'a __initdata annotation',
because some of it's data members refer to functions which will be
unloaded after init.

Consequently, its user decompress_method() will get the __init prefix.

Using a recursive call add a non-conflicting region in
__reserve_region_with_split() could result in a stack overflow in the case
that the recursive calls are too deep.  Convert the recursive calls to an
iterative loop to avoid the problem.

Tested on a machine containing 135 regions.  The kernel no longer panicked
with stack overflow.

Also tested with code arbitrarily adding regions with no conflict,
embedding two consecutive conflicts and embedding two non-consecutive
conflicts.

If prepare_reply() succeeds we have allocated memory for 'rep_skb'.  If
nla_reserve() then subsequently fails and returns NULL we fail to release
the memory we allocated, thus causing a leak.

Because udev use is so widespread, making the old static mapping the
default is too conservative, given the severe limitations it places on
usable AoE addresses.  Storage virtualization and larger shelves have made
the old limitations too confining.

These changes make the dynamic block device minor numbers the default,
removing the limitations on usable AoE addresses.

The static arrangement is still available with aoe_dyndevs=0, and the
aoe-stat tool from the userland aoetools package, the user space
counterpart to the aoe driver, recognizes the case where there is a
mismatch between the minor number in sysfs and the minor number in a
special device file.

The old mapping between AoE target shelf and slot addresses and the block
device minor number is retained as a backwards-compatible feature, with a
new "aoe_dyndevs" module parameter available for enabling dynamic block
device minor numbers.

The ATA over Ethernet protocol uses a major (shelf) and minor (slot)
address to identify a particular storage target.  These changes remove an
artificial limitation the aoe driver imposes on the use of AoE addresses.
For example, without these changes, the slot address has a maximum of 15,
but users commonly use slot numbers much greater than that.

The AoE shelf and slot address space is often used sparsely.  Instead of
using a static mapping between AoE addresses and the block device minor
number, the block device minor numbers are now allocated on demand.

The old area has a new URL.  Also, now that the driver can perform better,
it is worth mentioning the VM settings that help aoe to sink dirty pages
out early, avoiding unecessary memory pressure when much I/O is going on.
