This patch adds a new robust_list() syscall. The current syscall
can't be expanded to cover the following use case, so a new one is
needed. This new syscall allows users to set multiple robust lists per
process and to have either 32bit or 64bit pointers in the list.

Last time a whole list of short comings of the current robust scheme
were laid bare. I feel we should address all that if we're going to
create a new scheme.

Are you talking about [1] or is there something else?
