    mremap: fix race between mremap() and page cleanning
    
    Prior to 3.15, there was a race between zap_pte_range() and
    page_mkclean() where writes to a page could be lost.  Dave Hansen
    discovered by inspection that there is a similar race between
    move_ptes() and page_mkclean().
    
    We've been able to reproduce the issue by enlarging the race window with
    a msleep(), but have not been able to hit it without modifying the code.
    So, we think it's a real issue, but is difficult or impossible to hit in
    practice.
    
    The zap_pte_range() issue is fixed by commit 1cf35d47712d("mm: split
    'tlb_flush_mmu()' into tlb flushing and memory freeing parts").  And
    this patch is to fix the race between page_mkclean() and mremap().
    
    Here is one possible way to hit the race: suppose a process mmapped a
    file with READ | WRITE and SHARED, it has two threads and they are bound
    to 2 different CPUs, e.g.  CPU1 and CPU2.  mmap returned X, then thread
    1 did a write to addr X so that CPU1 now has a writable TLB for addr X
    on it.  Thread 2 starts mremaping from addr X to Y while thread 1
    cleaned the page and then did another write to the old addr X again.
    The 2nd write from thread 1 could succeed but the value will get lost.
    
            thread 1                           thread 2
         (bound to CPU1)                    (bound to CPU2)
    
      1: write 1 to addr X to get a
         writeable TLB on this CPU
    
                                            2: mremap starts
    
                                            3: move_ptes emptied PTE for addr X
                                               and setup new PTE for addr Y and
                                               then dropped PTL for X and Y
    
      4: page laundering for N by doing
         fadvise FADV_DONTNEED. When done,
         pageframe N is deemed clean.
    
      5: *write 2 to addr X
    
                                            6: tlb flush for addr X
    
      7: munmap (Y, pagesize) to make the
         page unmapped
    
      8: fadvise with FADV_DONTNEED again
         to kick the page off the pagecache
    
      9: pread the page from file to verify
         the value. If 1 is there, it means
         we have lost the written 2.
    
      *the write may or may not cause segmentation fault, it depends on
      if the TLB is still on the CPU.
    
    Please note that this is only one specific way of how the race could
    occur, it didn't mean that the race could only occur in exact the above
    config, e.g. more than 2 threads could be involved and fadvise() could
    be done in another thread, etc.
    
    For anonymous pages, they could race between mremap() and page reclaim:
    THP: a huge PMD is moved by mremap to a new huge PMD, then the new huge
    PMD gets unmapped/splitted/pagedout before the flush tlb happened for
    the old huge PMD in move_page_tables() and we could still write data to
    it.  The normal anonymous page has similar situation.
    
    To fix this, check for any dirty PTE in move_ptes()/move_huge_pmd() and
    if any, did the flush before dropping the PTL.  If we did the flush for
    every move_ptes()/move_huge_pmd() call then we do not need to do the
    flush in move_pages_tables() for the whole range.  But if we didn't, we
    still need to do the whole range flush.
    
    Alternatively, we can track which part of the range is flushed in
    move_ptes()/move_huge_pmd() and which didn't to avoid flushing the whole
    range in move_page_tables().  But that would require multiple tlb
    flushes for the different sub-ranges and should be less efficient than
    the single whole range flush.
    
    KBuild test on my Sandybridge desktop doesn't show any noticeable change.
