The patch titled
s390: alternate signal stack handling bug
has been added to the -mm tree. Its filename is
s390-alternate-signal-stack-handling-bug.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
From: Laurent Meyer <meyerlau@xxxxxxxxxx>
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.
