Unfortunately I forgot to check the date on the bogus scripts/mod/devicetable-offsets.h, so I don't know when it was generated. Usually, if you build in the source directory, a subsequent build in the output directory will tell you to run "make mrproper" in the source directory. That obviously didn't happen. Note that I did run "make tags" in the source directory. So far that never caused problems. Just checked, it does not create scripts/mod/devicetable-offsets.h. JFYI, putting back scripts/mod/devicetable-offsets.h by copying from a freshly generated one in the output directory, with the mei lines removed, resurrects the problem. Even after touching scripts/mod/devicetable-offsets.c afterwards, it is not regenerated.
