From: Aurelien Jarno <aurel...@aurel32.net>
LOAD POSITIVE instructions (LPR, LPGR and LPGFR) set the following
condition code:
0: Result zero; no overflow
1: --
2: Result greater than zero; no overflow
3: Overflow
The current code wrongly returns 1 instead of 2 in case of a result
greater than 0. This patches fixes that. This fixes the marshalling of
the value '0L' in Python.
