First, the siginfo preamble wasn't quite right; we need to indicate that we are padding up to 4 ints of preamble for 64-bit code, and then for compat mode we need to pad differently, using only 3 ints. Second, the C ABI requires a save area of two registers, not two pointers, since in compat mode we have 64-bit registers all of which we need to save, even though we only have 32-bit VAs.
