Yes, if you just swap RW_DATA_SECTION and .data1 so it looks like

RW_DATA_SECTION(SMP_CACHE_BYTES, 0, THREAD_SIZE)
.data1 : {
	*(.data1)
}

instead, that would preserve their relative locations.

Currently, switching to RW_DATA_SECTION would still result in a change in 
their relative position that .data.page_aligned and .data.nosave would be 
between .data and .data1 (not sure if that is relevant on sparc). (this 
will change when <http://lkml.org/lkml/2009/9/16/396> is merged).
