[SPARC64]: Use ASI_SCRATCHPAD address 0x0 properly.
This is where the virtual address of the fault status area belongs. To set it up we don't make a hypervisor call, instead we call OBP's SUNW,set-trap-table with the real address of the fault status area as the second argument. And right before that call we write the virtual address into ASI_SCRATCHPAD vaddr 0x0. Signed-off-by: David S. Miller <davem@davemloft.net>
