| 2011-04-20 | [S390] fix page table walk for changing page attributes | Jan Glauber | |
| The page table walk for changing page attributes used the wrong address for pgd/pud/pmd lookups if the range was bigger than a pmd entry. Fix the lookup by using the correct address.

| 2011-03-15 | [S390] Write protect module text and RO data | Jan Glauber | |
| Implement write protection for kernel modules text and read-only data sections by implementing set_memory_[ro|rw] on s390. Since s390 has no execute bit in the pte's NX is not supported. set_memory_[ro|rw] will only work on normal pages and not on large pages, so in case a large page should be modified bail out with a warning.
