Subject: x86,percpu: Move out of place 64 bit ops into X86_64 section
Date: Mon, 10 Jan 2011 10:35:23 -0600 (CST) [thread overview]
Message-ID: <alpine.DEB.2.00.1101101034290.12243@router.home> (raw)
Subject: x86,percpu: Move out of place 64 bit ops into X86_64 section
Some operations that operate on 64 bit operands are defined for 32 bit.
Move them into the correct section.
