From 9c1a125921d146f22cf28ff366ff69fd602a0e9b Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 26 May 2010 14:42:52 -0700 Subject: ptrace: unify FDPIC implementations The Blackfin/FRV/SuperH guys all have the same exact FDPIC ptrace code in their arch handlers (since they were probably copied & pasted). Since these ptrace interfaces are an arch independent aspect of the FDPIC code, unify them in the common ptrace code so new FDPIC ports don't need to copy and paste this fundamental stuff yet again.
