Matthew Brost 12b2285bf3 mm/zone_device: reinitialize large zone device private folios
Reinitialize metadata for large zone device private folios in
zone_device_page_init prior to creating a higher-order zone device private
folio.  This step is necessary when the folio's order changes dynamically
between zone_device_page_init calls to avoid building a corrupt folio.  As
part of the metadata reinitialization, the dev_pagemap must be passed in
from the caller because the pgmap stored in the folio page may have been
overwritten with a compound head.

Without this fix, individual pages could have invalid pgmap fields and
flags (with PG_locked being notably problematic) due to prior different
order allocations, which can, and will, result in kernel crashes.
