Heiko Carstens 5b1ba9e30c s390/mm,pageattr: add more page table walk sanity checks
The current page table walk code in pageattr.c only checks for large pages
while walking the kernel page table, but happily assumes that everything
else is just fine.
Add more checks so we never access invalid memory regions.
