Jeremy Kerr 0ffa899f4a powerpc/spufs: fix copy_to_user while atomic ... [ Upstream commit 88413a6bfbbe2f648df399b62f85c934460b7a4d ] Currently, we may perform a copy_to_user (through simple_read_from_buffer()) while holding a context's register_lock, while accessing the context save area. This change uses a temporary buffer for the context save area data, which we then pass to simple_read_from_buffer. Includes changes from Christoph Hellwig <hch@lst.de>.
