[SPARC64]: Fix fault handling in unaligned trap handler.
We were not calling kernel_mna_trap_fault() correctly. Instead of being fancy, just return 0 vs. -EFAULT from the assembler stubs, and handle that return value as appropriate. Create an "__retl_efault" stub for assembler exception table entries and use it where possible. Signed-off-by: David S. Miller <davem@davemloft.net>
