Subject: mm/page_reporting: change page_reporting_order to PAGE_REPORTING_ORDER_UNSPECIFIED
Date: Tue, 3 Mar 2026 03:30:32 -0800

page_reporting_order when uninitialised, holds a magic number -1.

Since we now maintain PAGE_REPORTING_ORDER_UNSPECIFIED as -1, which is
also a flag, set page_reporting_order to this flag.
