From 0c23590f00f85467b318ad0c20c36796a5bd4c60 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Mon, 4 May 2009 03:30:15 +0400 Subject: x86, 64-bit: ifdef out struct thread_struct::ip struct thread_struct::ip isn't used on x86_64, struct pt_regs::ip is used instead. kgdb should be reading 0 always, but I can't check it.
