* If < 0, it's an OPAL_ERR_* value * If >= 0, it's the actual output value of the function This is problematic for the OPAL_SOS stuff. This commit changes those functions to always return OPAL_* statuses and send the output value back through output parameters (like 95% of the rest of the code base). This avoids the confusion with OPAL_SOS stuff and makes paffinity work again (e.g., mpirun --bind-to-core ...). I updated all paffinitiy modules for the new function signatures, and bumped the paffinity API version up to 2.0.1. I don't think the version change will matter, though, because we'll be introducing support for hardware threads soon, which will either bump the paffinity version again or we'll replace paffinity with a new framework. This commit was SVN r23197.
