OK, I have got rid of SetPageUptodate_nowarn, and removed the atomic op from SetNewPageUptodate. Made PageUptodate_NoLock only issue the memory barrier is the page was uptodate (hopefully the compiler can thread the branch into the caller's branch).
SetNewPageUptodate does not do the S390 page_test_and_clear_dirty, so I'd like to make sure that's OK.
Rearranged the patch series so we don't have the first patch introducing a lot of WARN_ONs that are solved in the next two patches (rather, solve those issues first).
Thanks, Nick
