IOMMU Updates for Linux v3.13

This time the updates contain:

* Tracepoints for certain IOMMU-API functions to make
  their use easier to debug
* A tracepoint for IOMMU page faults to make it easier
  to get them in user space
* Updates and fixes for the new ARM SMMU driver after
  the first hardware showed up
* Various other fixes and cleanups in other IOMMU drivers

Here are the 3.13 KVM changes.  There was a lot of work on the PPC
side: the HV and emulation flavors can now coexist in a single kernel
is probably the most interesting change from a user point of view.
On the x86 side there are nested virtualization improvements and a
few bugfixes.  ARM got transparent huge page support, improved
overcommit, and support for big endian guests.

Finally, there is a new interface to connect KVM with VFIO.  This
helps with devices that use NoSnoop PCI transactions, letting the
driver in the guest execute WBINVD instructions.  This includes
some nVidia cards on Windows, that fail to start without these
patches and the corresponding userspace changes.

fbdev changes for 3.13

Nothing particularly stands out in this pull request. The biggest part of the
changes are cleanups.

Maybe one fix to mention is the "fb: reorder the lock sequence to fix potential
dead lock" which hopefully fixes the fb locking issues reported by multiple
persons.

There are also a few commits that have changes to arch/arm/mach-at91 and
arch/avr32, which have been acked by the maintainers.

Linux 3.12

Last-minute ACPI and power management fixes for 3.12

 - Revert epoll and select commits related to the freezer, introduced
   during the 3.11 cycle, that cause mysterious user space breakage
   to occur during resume from suspend to RAM for multiple users of
   32-bit x86 systems.  Material for 3.11.y stable kernels.

 - Revert a recent ACPI-based PCI hotplug (ACPIPHP) commit that was
   part of boot problem fixes for one machine, but turns out to cause
   issues with hotplug on Thunderbolt chains with multiple devices.
   It also turns out to be unnecessary after another fix in the
   same area that went in later.  From Mika Westerberg.
