Alexander Gordeev 4c88bb96e4 s390/mm: check 2KB-fragment page on release
When CONFIG_DEBUG_VM is defined check that pending remove
and tracking nibbles (bits 31-24 of the page refcount) are
cleared. Should the earlier stages of the page lifespan
have a race or logical error, such check could help in
exposing the issue.
