Yeah, that's clearer.

/*
* If your architecture has direct-mapped PTE pages (no HIGHPTE)
* then you just need to implement pte_offset_kernel() and include
* this in your asm/ptemap.h.
*
* To support HIGHPTE, you need to have implementations of
* kmap_atomic_pte() (which usually just calls kmap_atomic()),
* pmd_page() and pmd_index().
