I spent some time trying to use kgdb and debugged my inability to
resume from kgdb_handle_breakpoint(). NIP is not incremented

I've tested this lightly on a virtual instance with KDB enabled.
After the patch, I am able to get the "go"

Only that it was submitted too late for the last merge window, and I have not
yet begun processing patches for the next one. If you meant this to be a fix

Hi,
Any comments?

ec53500f "kvm: Add VFIO device" added a special KVM pseudo-device which is
used to handle any necessary interactions between KVM and VFIO.
Currently that device is built on x86 and ARM, but not powerpc, although
powerpc does support both KVM and VFIO. This makes things awkward in
