Since the code in book3s_64_vio_hv.c is called from real mode with HV
KVM, and therefore has to be built into the main kernel binary, this
makes it always built-in rather than part of the KVM module. It gets
called from the KVM module by PR KVM, so this adds

With this patch if HV is included, interrupts come in to the HV version
of the kvmppc_interrupt code, which then jumps to the PR handler,
renamed to kvmppc_interrupt_pr, if the guest is a PR guest. This helps

Hi All,
This patch series support enabling HV and PR KVM together in the same kernel. We
extend machine property with new property kvm_type. A value of HV will
force HV
KVM and PR PR KVM. If we don't specify kvm_type we will select the fastest
KVM mode.
ie, HV if that is supported otherwise PR.

irq_exit() is now called on the irq stack, which can trigger a switch
to the softirq stack from the irq stack. If an interrupt happens at
that point, we will not properly detect the re-entrancy and clobber

This fixes it. The side effect is to prevent

Do you really want module dependencies between vfio and your core
kernel MSI setup? Look at the vfio external user interface that we've
already defined.
That allows other components of the kernel to get a proper reference
