Hi,
I suppose we currently only need do the regset work, right? Attached is
the ia64 part, which mostly is a copy-paste of previous utrace patch
with some fixes. The issue is we have some duplicate code to access
registers. Will you add the ptrace_layout_access API? This could help
remove a lot of duplicate code.

Thanks,
Shaohua
