Hi Andi,
In linux-2.6.0-test10, I believe that there are several lines of code in the x86_64 version of handle_signal() that will not ever be executed and can most likely be removed.
I also believe that there are several lines that should be added to the end of the do_signal() routine for handling the -ERESTART_RESTARTBLOCK case.
Thank you.
