[POWERPC] spufs: add support for nonschedulable contexts
This adds two new flags to spu_create: SPU_CREATE_NONSCHED: create a context that is never moved away from an SPE once it has started running. This flag can only be used by tasks with the CAP_SYS_NICE capability. SPU_CREATE_ISOLATED: create a nonschedulable context that enters isolation mode upon first run. This requires the SPU_CREATE_NONSCHED flag. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
