Cleanup the pfault inline assemblies: - Use symbolic names for operands - Add extra linebreaks, and whitespace to improve readability In addition, change __pfault_init() to return -EOPNOTSUPP in case of an exception, and don't return a made up valid diag 258 return value (aka "8"). This allows to simplify the inline assembly, and makes debugging easier, in case something is broken.
