This patch is generated by this script:

find ./ -name "*.[ch]" -o -name "*.json" -o -name "trace-events" -type f \
| xargs sed -i "s/PC_DIMM/DIMM/g"

find ./ -name "*.[ch]" -o -name "*.json" -o -name "trace-events" -type f \
| xargs sed -i "s/PCDIMM/DIMM/g"

find ./ -name "*.[ch]" -o -name "*.json" -o -name "trace-events" -type f \
| xargs sed -i "s/pc_dimm/dimm/g"

find ./ -name "trace-events" -type f | xargs sed -i "s/pc-dimm/dimm/g"

It prepares the work which abstracts dimm device type for both pc-dimm and
nvdimm

In the following patches, dimm is a parent for nv-dimm and pc-dimm, so 
dimm is more abstract when nv-dimm and pc-dimm are more concrete. So for 
me it is strange, that all these files, all old staff will use an 
abstract dimm. What the purpose of pc-dimm in this case (which appeared 
in the following patches)?

The '-type f' binds only to the '-name trace-events' clause, and not the
'name "*.[ch]"' or '-name "*.json"', but since we don't have any
directories by those names, it didn't matter.  You probably could have
eliminated the -type f with no consequences, rather than adding "(" and
")".  In fact, you could have used git rather than find to do it:

git grep -il 'pc_\?dimm' | xargs ...

which finds only one additional instance of pc_dimm in
stubs/Makefile.objs - so maybe you should:

git mv stubs/qmp_{pc_,}dimm_device_list.c

either in this patch or as a followup.

Could compress these three sed lines into one, if desired:
find ... | xargs sed -i 's/pc_\?\(dimm\)/\1/ig'

But doesn't really matter.  I'm fine if you leave your commit message
as-is, and will let you decide what to do about the stub file name.

Touches public interface files, but does not affect ABI, so it is safe.

The logic pc-dimm used can be completely shared by NVDIMM, so we abstracted 'dimm' from pc-dimm,
and let the common code handle dimm instead of pc-dimm so that the common code will handle NVDIMM
automatically.

Actually, pc-dimm just inherit things from dimm, it does not have personal data.

I can see two ways this patchset can get merged
- merge refactorings first, nvdimm support on top
- merge nvdimm support first, refactor code on top

The way you put it in the middle of the series
allows neither.  And I definitely favor option 2:
it's easier to reason about the best way to refactor code
when you have multiple users before you.
