I need a bit more context to try to analyse this.
Where did you expect _restgpr_20_x to be defined.
If in vmlinux then were they present in the
Module.symvers file?
If in the linked in .o file - could you
see the symbols using objdump.
etc.
Sorry - not much help right away.
PS. Travelling - do not expect responses until the
weekend.
