In support of enabling memory_failure() handling for device-dax mappings, set ->index to the pgoff of the page. The rmap implementation requires ->index to bound the search through the vma interval tree. The ->index value is never cleared. There is no possibility for the page to become associated with another pgoff while the device is enabled. When the device is disabled the 'struct page' array for the device is destroyed and ->index is reinitialized to zero.
