Thanks.

None of the functions I have moved from *-stub.c to stubs/ operate on a
single CPU, so now that the conflict with the kdump format support has
been resolved I'd like to move them as a step towards dropping
per-target configure changes for guest-memory-dump support.

With my note in the cover letter I was rather referring to
cpu_paging_enabled(), which is mandatory currently without any stub.

Do you have a concrete suggestion what else to do for these stubs?
