    [PATCH] x86: Work around gcc 4.2 over aggressive optimizer · 1bac3b38
    Andi Kleen authored
    The new PDA code uses a dummy _proxy_pda variable to describe
    memory references to the PDA. It is never referenced
    in inline assembly, but exists as input/output arguments.
    gcc 4.2 in some cases can CSE references to this which causes
    unresolved symbols.  Define it to zero to avoid this.
