Subject: [PATCH 0/8] KVM: Remove include/kvm, standardize includes
Kill off include/kvm (through file moves/renames), and standardize the set of
KVM includes across all architectures.
This conflicts with Colton's partioned PMU series[1], but this should work as
a nice prepatory cleanup for the partitioned PMU work (and hopefully can land
sooner).
Note, these patches were originally posted as part of a much larger and more
agressive RFC[1]. We've effectively abandoned upstreaming the multi-KVM idea,
but I'm trying to (slowly) upstream the bits and pieces that I think/hope are
generally beneficial.

Anish Ghulati (1):
KVM: arm64: Move arm_{psci,hypercalls}.h to an internal KVM path
Sean Christopherson (7):
KVM: arm64: Include KVM headers to get forward declarations
KVM: arm64: Move ARM specific headers in include/kvm to arch directory
KVM: Move include/kvm/iodev.h to include/linux as kvm_iodev.h
KVM: MIPS: Stop adding virt/kvm to the arch include path
KVM: PPC: Stop adding virt/kvm to the arch include path
KVM: s390: Stop adding virt/kvm to the arch include path
KVM: Standardize include paths across all architectures
