Martin Schwidefsky 0d201ff077 s390/lib: use expoline for indirect branches ...

[ Upstream commit 97489e0663 ]

The return from the memmove, memset, memcpy, __memset16, __memset32 and
__memset64 functions are done with "br %r14". These are indirect branches
as well and need to use execute trampolines for CONFIG_EXPOLINE=y.
