Everything??  not just the CONFIG_* namespace violations?

[If so,] Potentially 3600 changes just in 3 header files, then all of
the corresponding .c files.  No thanks.

How about a note in the header files that explains that CONFIG_* register
names are spelled as "CNFG_*" so that there are not kernel kconfig
namespace conflicts?
