These newer macros are used by strace if they are defined. I recommend updating asm-ia64/ptrace_offsets.h to the current 2.6 version; there doesn't appear to be anything problematic in the changes.
Created attachment 104027 [details] patch to update asm-ia64/ptrace_offsets.h Here is a patch that updates asm-ia64/ptrace_offsets.h to match the current 2.6 header. It only changes comments and adds these two new macros. Please put this in already!
