History
Jeremy Fitzhardinge 7f01507234 [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.
