[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: mm: place __private in correct place, const-ify __mm_flags_get_word
has been removed from the -mm tree.  Its filename was
     mm-add-bitmap-mm-flags-field-fix.patch

This patch was dropped because it was folded into mm-add-bitmap-mm-flags-field.patch

Subject: mm: place __private in correct place, const-ify __mm_flags_get_word
Date: Wed, 13 Aug 2025 20:40:10 +0100

The __private sparse indicator was placed in the wrong location, resulting
in sparse errors, correct this by placing it where it ought to be.

Also, share some code for __mm_flags_get_word() and const-ify it to be
consistent.

Finally, fixup inconsistency in __mm_flags_set_word() param alignment.
