                * exceptions.c: Include <hurd/slab.h> and "as.h".
                (exception_frame_slab): New local variable.

                (exception_handler_activated): ... to this.  Update callers.  
Only
                handle the fault if the fault corresponds to the page the stack
                pointer references at the time of the fault or the next stack
                page.
                (exception_handler_normal): New function.
                (exception_handler_init): Initialize exception_frame_slab.
                * ia32-exception-entry.S (EXCEPTION_STACK): New macro.

                (EF_STACK_START): Likewise.
                (EF_NEXT): Likewise.
                (exception_handler_entry): After calling
                exception_handler_activated, check if the return result is
                non-zero.  If so, call exception_handler_normal.

                * server.c (server_loop): When marshalling the fault, return the
                current stack pointer, consistent with the updated interface.
