Re: [PATCH] Avoid DT_TEXTREL on s390*

Hello Jakub,

Doing PLT calls is a bit awkward as the ABI requires the GOT
register to be set up before calling a PLT stub.  Also, the
code should work in the non-PIC case as well.  Thus I agree
that making the helper function hidden is the best solution.

I guess we should do that.  With this addition, your patch is OK;
if you've tested your change, could you please commit it?

 Mit freundlichen Gruessen / Best Regards
