Arnd, thanks for dealing with this.

There are a number of tile-specific driver files that are mostly called out
in the MAINTAINERS file.  I would expect you should also delete those.

-F:    drivers/char/tile-srom.c
-F:    drivers/edac/tile_edac.c
-F:    drivers/net/ethernet/tile/
-F:    drivers/rtc/rtc-tile.c
-F:    drivers/tty/hvc/hvc_tile.c
-F:    drivers/tty/serial/tilegx.c
-F:    drivers/usb/host/*-tilegx.c
-F:    include/linux/usb/tilegx.h
