do_rt_sigreturn uses an uninitialised local variable instead of fetching the old signal mask directly from the signal frame when restoring the mask, so the signal mask is undefined after do_rt_sigreturn. As the signal frame data is in target-endian order, target_to_host_sigset instead of target_to_host_sigset_internal is required. do_sigreturn is correct in using target_to_host_sigset_internal, because get_user already did the endianness conversion.
