    [XFS] eagerly remove vmap mappings to avoid upsetting Xen
    
    XFS leaves stray mappings around when it vmaps memory to make it virtually
    contigious. This upsets Xen if one of those pages is being recycled into a
    pagetable, since it finds an extra writable mapping of the page.
    
    This patch solves the problem in a brute force way, by making XFS always
    eagerly unmap its mappings.
