I think he means how to handle the following from include/linux/gfp.h in
valgrind:

    struct page *alloc_pages(gfp_t gfp_mask, unsigned int order);
    unsigned long __get_free_pages(gfp_t gfp_mask, unsigned int order);

    void __free_pages(struct page *page, unsigned int order);
    void free_pages(unsigned long addr, unsigned int order);

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
