Linus,

this merge needs one manual conflict resolution that is foretold in
3d9cd95f90b2 ("ARM: gic-v3: Work around definition of gic_write_bpr1").
The commit says that the conflict is "obvious to resolve", but
linux-next got it wrong, so I have pasted the correct resolution at the
bottom -- inline assembly and surrounding #if should be removed, because
the #if would always select the write_sysreg() branch.

The following changes since commit fa8410b355251fd30341662a40ac6b22d3e38468:

Linux 4.8-rc3 (2016-08-21 16:14:10 -0700)

Merge tag 'kvm_mips_4.9_1' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/kvm-mips into next (2016-09-29 16:26:52 +0200)

----------------------------------------------------------------
KVM updates for v4.9-rc1

Common code:
Move `make kvmconfig` stubs from x86; use 64 bits for debugfs stats.

ARM:
Important fixes for not using an in-kernel irqchip; handle SError
exceptions and present them to guests if appropriate; proxying of GICV
access at EL2 if guest mappings are unsafe; GICv3 on AArch32 on ARMv8;
preparations for GICv3 save/restore, including ABI docs; cleanups and
a bit of optimizations.

MIPS:
A couple of fixes in preparation for supporting MIPS EVA host kernels;
MIPS SMP host & TLB invalidation fixes.

PPC:
Fix the bug which caused guests to falsely report lockups; other minor
fixes; a small optimization.

s390:
Lazy enablement of runtime instrumentation; up to 255 CPUs for nested
guests; rework of machine check deliver; cleanups and fixes.

x86:
IOMMU part of AMD's AVIC for vmexit-less interrupt delivery; Hyper-V
TSC page; per-vcpu tsc_offset in debugfs; accelerated INS/OUTS in
nVMX; cleanups and fixes.
