Oh, and on this side - I really think the "convert drivers / headers"
should be driven by some automated script.

Literally something that does the equivalent of

   for i in include/linux/mod_device_id/*.h
   do

     # The new include line
     line=$(echo $i | sed 's:include/\(.*\)$:#include <\1>:')

     # get the struct name with grep/sed/whatever
     struct_name=$(grep 'struct.*device_id.*{' $i | ...)

     # find any users of it, insert new include
     git grep -l "struct $struct_name" -- '*.c' |
        xargs sed -i "/mod_devicetable.h/a $line"

   done

and after that has script (and by "that script" I don't mean the
above, but some fixed and fleshed-out version that does something
similar) has added all the new includes after the existing
"mod_devicetable.h" include, a final script just removes the
mod_devicetable.h include lines entirely.

That obviously implies that you should also do that "struct cpu_feature" thing.

Anyway, I *think* it's scriptable using something like the above - a
competent person would probably rewrite it into something like perl,
but I'm old and a 'shell script and sed' kind of person, so the above
is meant as a "you get the idea, I'm sure, and can improve on my
broken scripting".

Because doing the 1600+ existing includes by hand sounds like a nightmare.
