Subject: [PATCH] powerpc: exported functions __clear_user and copy_page use r2 so need _GLOBAL_TOC()
Date: Thu, 5 Jun 2014 08:04:39 +1000 [thread overview]
Message-ID: <20140605080439.34de3dc0@kryten> (raw)
__clear_user and copy_page load from the TOC and are also exported
to modules. This means we have to use _GLOBAL_TOC() so that we
create the global entry point that sets up the TOC.
