On PPC64, put_sigset_t converts a sigset_t to a compat_sigset_t before copying it to userspace. There is a typo in the case that we have 4 words to copy, meaning that we corrupt the compat_sigset_t. It appears that _NSIG_WORDS can't be greater than 2 at the moment so this code is probably always optimised away anyway.
