Cover letter [PATCH 0/5] SPU file system for 2.6.15-rc-mm
I'd like to have the SPU file system included in the -mm kernel to get broader review and eventually have it merged in 2.6.16.
This version now puts all the spufs files under arch/powerpc/platforms/cell/spufs instead of fs/spufs, since it is really specific to that platform.
The interface has now stabilized on a set of files per logical SPU that can be accessed with read/write and sometime poll or mmap but not ioctl as well as two new system calls, spu_run and spu_create.
As discussed, the system call numbers that I am using here conflict with those from the perfmon patches, so I'm moving the perfmon syscall range to start at 280. This means that the first patch gets to be applied on top of perfmon2-reserve-system-calls-reserve-spu-slots.patch.
