Jens Remus 160e19b95b s390/vdso: Add CFI for RA register to asm macro vdso_func 
[ Upstream commit b961ec10b9 ]

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.

[1]: s390x ELF ABI, https://github.com/IBM/s390x-abi/releases
