A zero value for prot_sect in the memory types table implies that section mappings should never be created for the memory type in question. This is checked for in alloc_init_section().
With LPAE, we set a bit to mask access flag faults for kernel mappings. This breaks the aforementioned (!prot_sect) check in alloc_init_section().
This patch fixes this bug by first checking for a non-zero prot_sect before setting the PMD_SECT_AF flag.
