From 8dc86ab954d28513f75918d743c40cddbff7388a Mon Sep 17 00:00:00 2001 From: Geoff Levand Date: Mon, 20 Nov 2006 18:44:56 +0100 Subject: [POWERPC] Change ppc_rtas declaration to weak Change the definition of powerpc's cond_syscall() to use the standard gcc weak attribute specifier which provides proper support for C linkage as needed by spu_syscall_table[].
