Okay, I withdraw the patch: Upon further consideration it is note really clear what the intended behavior of set_memory_*() on address ranges with mapping holes is supposed to be. The original issue was with set_memory_nx() (called from mark_rodata_ro()) stumbling across an unmapped region (resulting from an out of tree change completely unmapping the kernel mappings of address ranges passed to free_init_pages()). I simply don't have the time to check whether the unmapping done with CONFIG_DEBUG_PAGEALLOC would have a similar effect. The net result in any event were pages (past the hole) reported as problematic when CONFIG_DEBUG_WX is enabled. Jan
