It reuses the work already done for PPC64. This series is based on today's next-test (f538b53fd47a) where main patchs from v5 are merged in. The first patch is important for performance. v6: - Forced scv param to 0 on syscall_exit_prepare(), and added is_not_scv bool. - Reworked the last patch to avoid code duplication.
