Subject: [PATCH 29/40] trace syscalls, PPC: Convert ppc32_ syscalls to ARCH_COMPAT_SYSCALL_DEFINE

From: Ian Munsie <imunsie@....ibm.com>

This patch renames the 32bit compat syscalls prefixed with ppc32_ to
sys32_ and uses the ARCH_COMPAT_SYSCALL_DEFINE macros to record their
metadata for tracing.
