Heiko Carstens 13f9eec229 s390: always clear kernel stack backchain before calling functions
[ Upstream commit 9365965db0 ]

Clear the kernel stack backchain before potentially calling the
lockdep trace_hardirqs_off/on functions. Without this walking the
kernel backchain, e.g. during a panic, might stop too early.
