The patch titled
Subject: mm-add-generic-ptdump-v15
has been removed from the -mm tree. Its filename was
mm-add-generic-ptdump-v15.patch
This patch was dropped because it was folded into mm-add-generic-ptdump.patch
------------------------------------------------------
From: Steven Price <steven.price@xxxxxxx>
Subject: mm-add-generic-ptdump-v15
Switch walk_page_range() into two functions, the existing
walk_page_range() now still requires VMAs (and treats areas without a VMA
as a 'hole'). The new walk_page_range_novma() ignores VMAs and will
report the actual page table layout. This fixes the previous breakage of
/proc/<pid>/pagemap
