[SPARC64]: Mark most of initial bootup asm as .text.init.ref_ok
We can't mark the whole thing init because there are dependencies in bootloaders that assume that _start, or whatever the image entry value, is 2 instructions before the "HdrS" signature. In fact, TILO assumes this entry is always at 0x4000, yikes! Also, right after the bootloader info area there are OBP strings and values that get used later in the boot process, and those are not all provably .init yet. Signed-off-by: David S. Miller <davem@davemloft.net>
