Hopefully I'm just missing something obvious, but when I call memblock_reserve (in .38) to reserve a block of memory away from the general kernel memory pool, I find that an ioremap of memory within the reserved block still fails because pte_valid() is apparently true. Is this intended behavior? If so, what would the correct way of separating memory from the system be so that there is no longer a 1-to-1 1M mapping for this memory and ioremap (creating the *only* mapping for this memory) is allowed? Thanks.
