Jens Remus 3497c0bec9 s390/vdso: Add CFI for RA register to asm macro vdso_func
[ Upstream commit b961ec10b9f9719987470236feb50c967db5a652 ]

The return-address (RA) register r14 is specified as volatile in the
s390x ELF ABI [1]. Nevertheless proper CFI directives must be provided
for an unwinder to restore the return address, if the RA register
value is changed from its value at function entry, as it is the case.
