This patch adds support for additional flags at spu_create, which relate to the establishment of affinity between contexts and contexts to memory. A fourth, optional, parameter is supported. This parameter represent a affinity neighbor of the context being created, and is used when defining SPU-SPU affinity. Affinity is represented as a doubly linked list of spu_contexts.

One of the two users of spufs_calls.owner still has a race when calling try_module_get while the module is removed. This makes it use the correct instance of owner. Noticed by Milton Miller. Signed-off-by: NArnd Bergmann <arndb@de.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

try_module_get returns true when NULL arguments, so we first need to check if there is a module loaded before getting the reference count. Signed-off-by: NArnd Bergmann <arndb@de.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

This is the current version of the spu file system, used for driving SPEs on the Cell Broadband Engine. This release is almost identical to the version for the 2.6.14 kernel posted earlier, which is available as part of the Cell BE Linux distribution from http://www.bsc.es/projects/deepcomputing/linuxoncell/. The first patch provides all the interfaces for running spu application, but does not have any support for debugging SPU tasks or for scheduling. Both these functionalities are added in the subsequent patches. See Documentation/filesystems/spufs.txt on how to use spufs.
