Authored by David S. Miller

Exists in master and in 4 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN, v3.2_SMARCT335xPSP_04.06.00.11

[SPARC64]: Explicitly print return PC when the kernel fault PC is bogus. 

That way we'll have at least some debugging info even if
the stack dump explodes.
