Unless CONFIG_HIGHPTE is not set the allocation should be using highmem:

-----------------------------------------------------------------------
pgtable_t pte_alloc_one(struct mm_struct *mm, unsigned long address)
{
        struct page *pte;

#ifdef CONFIG_HIGHPTE
        pte = alloc_pages(GFP_KERNEL|__GFP_HIGHMEM|__GFP_REPEAT|
__GFP_ZERO, 0);
#else
        pte = alloc_pages(GFP_KERNEL|__GFP_REPEAT|__GFP_ZERO, 0);
#endif
        if (pte)
                pgtable_page_ctor(pte);
        return pte;
}
