Created attachment 14081
  --> https://sourceware.org/bugzilla/attachment.cgi?id=3D14081&action=3Ded=
it
v2 of the patch

Found that runtime/linux/regs.c had a macro to access to ret_addr field so
updated the macro to do the right thing when CONFIG_KRETPROBE_ON_RETHOOK is=
 set
and just have the tapsets.cxx generated code also uses that macro.

Running the systemtap.examples/check.exp tests on 86_64 rawhide and f35 to =
see
that the patch doesn't cause any regressions.
