From 5a4fa1639622b85d7e4422242308fc6cef7e503e Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Tue, 23 May 2006 07:46:38 -0700 Subject: [PATCH] powerpc: fill hole in Cell SPU syscall table Syscall number 224 was absent from the table, which I believe means that the SPU can cause an oops by attempting to use it.
