Unless there is a user that wants to keep maintaining these, we can probably remove all this code soon, e.g. after the next LTS kernel. CONFIG_SPU_FS is shared with the PS3 platform, which is still used and maintained. The bit I don't know is how common it is to actually still use spufs on the PS3. Support for spu programs was removed in gcc-9.1 and gdb-8.3, so none of the major distros even ship old enough toolchains any more, but existing applications and older toolchains should still work for people that have them and want to run new kernels. Geoff, are you using spufs on ps3, and if so, should we move arch/powerpc/platforms/cell/spu* to the PS3 entry in the MAINTAINERS file? I don't think there is any advantage in actually moving the files to platforms/ps3 if we delete the cell blade support. Arnd
