    This gives the following compile error with
    -Werror-implicit-function-declaration:

    CC arch/i386/mm/ioremap.o
    /home/bunk/linux/kernel-2.6/linux-2.6.18-rc4-mm1/arch/i386/mm/ioremap.c:
    In function ‘ioremap_nocache’:
    /home/bunk/linux/kernel-2.6/linux-2.6.18-rc4-mm1/arch/i386/mm/ioremap.c:142:
    error: implicit declaration of function ‘change_page_attr’

    error: implicit declaration of function ‘global_flush_tlb’

    <-- snip -->

    If anyone with CONFIG_X86_PAE=y experiences runtime stack corruption,
    the patch below might help.
