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