One bug fix and three reverts. The reverts back out the slightly
controversial feeding the entire device tree into the random pool and
the reserved-memory binding which isn't fully baked yet. Expect the
reserved-memory patches at least to resurface for v3.13. The bug fixes
removes a scary but harmless warning on SPARC that was introduced in the
v3.12 merge window. v3.13 will contain a proper fix that makes the new
code work on SPARC.
On the plus side, the diffstat looks *awesome*. I love removing lines of code.

This reverts commit 109b6236294b53d8eaa50be7d9e9ad37079f5f7e.
Tim Bird expressed concern that this will have a bad effect on boot
time, and while simple tests have shown it to be okay with simple tree,
a device tree blob can potentially be quite large and
add_device_randomness() is not a fast function. Rather than do this for
all platforms unconditionally, I'm reverting this patch and would like
to see it revisited. Instead of feeding the entire tree into the random
pool, it would probably be appropriate to hash the tree and feed the
hash result into the pool. There really isn't a lot of randomness in a
device tree anyway. In the majority of cases only a handful of
properties are going to be different between machines with the same
baseboard.

Not all DT platforms have all the cpus collected under a /cpus node.
That just happens to be a details of FDT, ePAPR and PowerPC platforms.
Sparc does something different, but unfortunately the current code
complains with a warning if /cpus isn't there. This became a problem
with commit f86e4718, "driver/core cpu: initialize of_node in cpu's
device structure", which caused the function to get called for all
architectures.
This commit is a temporary fix to fail silently if the cpus node isn't
present. A proper fix will come later to allow arch code to provide a
custom mechanism for decoding the CPU hwid if the 'reg' property isn't
appropriate.

And one pain in the ass revert, so we have VGA arbitration that when
implemented 4-5 years ago really hoped that GPUs could remove
themselves from arbitration completely once they had a kernel driver.
It seems Intel hw designers decided that was too nice a facility to
allow us to have so they removed it when they went on-die (so since
Ironlake at least). Now Alex Williamson added support for VGA
arbitration for newer GPUs however this now exposes itself to
userspace as requireing arbitration of GPU VGA regions and the X
server gets involved and disables things that it can't handle when VGA
access is possibly required around every operation.
So in order to not break userspace we just reverted things back to the
old known broken status so maybe we can try and design out way out.
Ville also had a patch to use stop machine for the two times Intel
needs to access VGA space, that might be acceptable with some rework,
but for now myself and Daniel agreed to just go back"

In vfio_iommu_type1.c there is a bug in vfio_dma_do_map, when checking
that pages are not already mapped. Since the check is being done in a
for loop nested within the main loop, breaking out of it does not create
the intended behavior. If the underlying IOMMU driver returns a non-NULL
value, this will be ignored and mapping the DMA range will be attempted
anyway, leading to unpredictable behavior.
This interracts badly with the ARM SMMU driver issue fixed in the patch
that was submitted with the title:
"[PATCH 2/2] ARM: SMMU: return NULL on error in arm_smmu_iova_to_phys"
Both fixes are required in order to use the vfio_iommu_type1 driver
with an ARM SMMU.
This patch refactors the function slightly, in order to also make this
kind of bug less likely.

This reverts commit 81b5c7bc8de3e6f63419139c2fc91bf81dea8a7d.
Adding drm/i915 into the vga arbiter chain means that X (in a piece of
well-meant paranoia) will do a get/put on the vga decoding around
_every_ accel call down into the ddx. Which results in some nice
performance disasters [1]. This really breaks userspace, by disabling
DRI for everyone, and stops OpenGL from working, this isn't limited
to just the i915 but both the integrated and discrete GPUs on
multi-gpu systems, in other words this causes untold worlds of pain,
Ville tried to come up with a Great Hack to fiddle the required VGA
I/O ops behind everyone's back using stop_machine, but that didn't
really work out [2]. Given that we're fairly late in the -rc stage for
such games let's just revert this all.
One thing we might want to keep is to delay the disabling of the vga
decoding until the fbdev emulation and the fbcon screen is set up. If
we kill vga mem decoding beforehand fbcon can end up with a white
square in the top-left corner it tried to save from the vga memory for
a seamless transition. And we have bug reports on older platforms
which seem to match these symptoms.
But again that's something to play around with in -next.

This patch is to prevent hpwdt from loading on any auxilary iLO devices defined
after the initial (or main) iLO device. All auxilary iLO devices will have a
subsystem device ID set to 0x1979 in order for hpwdt to differentiate between
the two types.

Allow architectures which have a disabled get_cycles() function to
provide a random_get_entropy() function which provides a fine-grained,
rapidly changing counter that can be used by the /dev/random driver.
For example, an architecture might have a rapidly changing register
used to control random TLB cache eviction, or DRAM refresh that
doesn't meet the requirements of get_cycles(), but which is good
enough for the needs of the random driver.
