[PATCH] s390: alternate signal stack handling bug
If a signal handler has been established with the SA_ONSTACK option but no
alternate stack is provided with sigaltstack(), the kernel still tries to
install the alternate stack. Also when setting an alternate stack with
sigalstack() and the SS_DISABLE flag, the kernel tries to install the
alternate stack on signal delivery. Use the correct conditions sas_ss_flags()
to check if the alternate stack has to be used.
