Subject: [x86] warning: parameter has incomplete type

Hello.

Is there a patch to suppress below warning messages (which are printed for every
file when compiling kernel using gcc 3.3.5)?

Regards.

    x86: move pte types into pgtable*.h

    pgtable*.h is intended for definitions relating to actual pagetables
    and their entries, so move all the definitions for
    (pte|pmd|pud|pgd)(val)?_t to the appropriate pgtable*.h headers.
