From: Michael Ellerman Date: Wed, 19 Sep 2007 04:38:12 +0000 (+1000) Subject: [POWERPC] spufs: Internal __spufs_get_foo() routines should take a spu_context * X-Git-Tag: firefly_0821_release~26066^2~214 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=74de08bc10dd4d67870cf5b6c5aaf6875cd869c5;p=firefly-linux-kernel-4.4.55.git [POWERPC] spufs: Internal __spufs_get_foo() routines should take a spu_context * The SPUFS attribute get routines take a void * because the generic attribute code doesn't know what sort of data it's passing around. However our internal __spufs_get_foo() routines can take a spu_context * directly, which saves plonking it in and out of a void * again.
