  dax: Fix missed wakeup with PMD faults (2019-07-16 19:30:59 -0700)

----------------------------------------------------------------
- Fix a hang condition that started triggering after the Xarray
  conversion of fsdax in the v4.20 kernel.

- Add a 'resource' (root-only physical base address) sysfs attribute to
  device-dax instances to correlate memory-blocks onlined via the kmem
  driver with a given device instance.
