From: Ian Munsie <imun...@au1.ibm.com> This patch alters the trivial syscalls (with a return type of long) in PPC to use the SYSCALL_DEFINE family of macros to record their metadata for ftrace syscalls.
It does not alter any non-trivial syscalls with different return types. Several of the syscalls with a ppc_ prefix are renamed by this patch to have a sys_ppc_ prefix so that they can be used easily with the SYSCALL_DEFINE macro.
