This patch makes it possible for userspace to implement setproctitle()
cleanly.  It adds a new PR_SET_PROCTITLE_AREA option for prctl(), which
updates task's mm_struct->arg_start and arg_end to the given area.

Why can't we make this a proper system call?

I don't think this is big matter. Does using syscall have any benefit?
I don't have strong mention. merely, Timo's original proposal used
prctl.
