[PATCH] spufs: Make all exports GPL-only

[Arnd Bergmann]

This changes all exported symbols of spufs to EXPORT_SYMBOL_GPL.
The spu_ibox_read/spu_wbox_write symbols are not exported
any more when the scheduler patch is applied.

Lack of thinking ;-)
At first, I had everything as EXPORT_SYMBOL. Everything that was added
in the last few months was EXPORT_SYMBOL_GPL.
