It is being referenced from arch/x86/kernel/cpu/hypervisor.c
But wasn't it also removed from the list of externs?
Rereading the .h file, no it wasn't. I missed that.
Perhaps the extern list could be reordered to move this
x86_hyper_xen_hvm to be next to x86_hyper_type.
I also suggest that "extern bool nopv" might be a bit
non-specific and could use a longer identifier.
You are a little bit late. It has been this way since V5 of the series
posted on July 3rd.
I have pushed the series to my tree already and I'm about to send the
pull request.
Followup patches welcome. :-)
