Pull tracing update from Steven Rostedt:
"This batch of changes is mostly clean ups and small bug fixes. The
only real feature that was added this release is from Namhyung Kim,
who introduced "set_graph_notrace" filter that lets you run the
function graph tracer and not trace particular functions and their
call chain.
Tom Zanussi added some updates to the ftrace multibuffer tracing that
made it more consistent with the top level tracing.
One of the fixes for perf function tracing required an API change in
RCU; the addition of "rcu_is_watching()". As Paul McKenney is pushing
that change in this release too, he gave me a branch that included all
the changes to get that working, and I pulled that into my tree in
order to complete the perf function tracing fix"

Openrisc's private vmlinux.h duplicates a few definitions that are already
provided by asm-generic/sections.h. The former is used by setup.c only,
while the latter is already used everywhere else.
Convert setup.c to use the generic version:
- Include <asm/sections.h>,
- Remove the (slightly different) extern declarations,
- Remove the no longer needed address-of ('&') operators.

For BF537_FAMILY, when offset != 1, the mask is 1.
Thus add proper mask for comparing pfunc with function.
Also has small refactor for better readability.
In portmux_setup(), it looks odd having "pmux &= ~(3 << 1);"
while in current code we do pmux |= (function << offset);.

Pull KVM changes from Paolo Bonzini:
"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"

Pull Xen updates from Konrad Rzeszutek Wilk:
"This has tons of fixes and two major features which are concentrated
around the Xen SWIOTLB library.
The short <blurb> is that the tracing facility (just one function) has
been added to SWIOTLB to make it easier to track I/O progress.
Additionally under Xen and ARM (32 & 64) the Xen-SWIOTLB driver
"is used to translate physical to machine and machine to physical
addresses of foreign[guest] pages for DMA operations" (Stefano) when
booting under hardware without proper IOMMU.
There are also bug-fixes, cleanups, compile warning fixes, etc.
The commit times for some of the commits is a bit fresh - that is b/c
we wanted to make sure we have the Ack's from the ARM folks - which
with the string of back-to-back conferences took a bit of time. Rest
assured - the code has been stewing in #linux-next for some time.
Features:
- SWIOTLB has tracing added when doing bounce buffer.
- Xen ARM/ARM64 can use Xen-SWIOTLB. This work allows Linux to
safely program real devices for DMA operations when running as a
guest on Xen on ARM, without IOMMU support. [*1]
- xen_raw_printk works with PVHVM guests if needed.
Bug-fixes:
- Make memory ballooning work under HVM with large MMIO region.
- Inform hypervisor of MCFG regions found in ACPI DSDT.
- Remove deprecated IRQF_DISABLED.
- Remove deprecated __cpuinit.
[*1]:
"On arm and arm64 all Xen guests, including dom0, run with second
stage translation enabled. As a consequence when dom0 programs a
device for a DMA operation is going to use (pseudo) physical
addresses instead machine addresses. This work introduces two trees
to track physical to machine and machine to physical mappings of
foreign pages. Local pages are assumed mapped 1:1 (physical address
== machine address). It enables the SWIOTLB-Xen driver on ARM and
ARM64, so that Linux can translate physical addresses to machine
addresses for dma operations when necessary. " (Stefano)"
