Subject: [PATCH] powernv: Use _GLOBAL_TOC for opal wrappers
Date: Wed, 22 Oct 2014 11:32:52 +0800 [thread overview]
Message-ID: <1413948772.62479.492398078454.1.gpush@pablo> (raw)
Currently, we can't call opal wrappers from modules when using the LE
ABIv2, which requires a TOC init.
This change uses the _GLOBAL_TOC() macro (rather than _GLOBAL) for the
opal wrappers, so that we can do non-local calls to them.
