parisc: Avoid trashing MPE IPL bootloader stack The MPE IPL boot loader calls PDC_MODEL when running in narrow mode. The return buffer pointed to by arg2 holds space for eigth 32-bit integers directly followed by the stack used by MPE. So, when pdc_model() writes 32 64-bit integers to arg2, it unintentionally overwrites MPE's call stack. Fix it by limiting returned bytes depending if PDC_MODEL was called in WIDE or NARROW mode.
