From 8f18a158192ef6dc63a572bdbbdf5613cfbbe2e4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 4 Jun 2007 23:26:51 +1000 Subject: [PATCH] [POWERPC] spufs: Refuse to load the module when not running on cell As noticed by David Woodhouse, it's currently possible to mount spufs on any machine, which means that it actually will get mounted by fedora. This refuses to load the module on platforms that have no support for SPUs.
