Heiko Carstens 3e76ee99b0 s390/mm: always use PAGE_KERNEL when mapping pages
Always use PAGE_KERNEL when re-enabling pages within the kernel
mapping due to debug pagealloc. Without using this pgprot value
pte_mkwrite() and pte_wrprotect() won't work on such mappings after an
unmap -> map cycle anymore.
