The patch titled
Subject: arm: define __PAGETABLE_PMD_FOLDED for !LPAE
has been removed from the -mm tree. Its filename was
arm-define-__pagetable_pmd_folded-for-lpae.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: "Kirill A. Shutemov" <kirill.shutemov@xxxxxxxxxxxxxxx>
Subject: arm: define __PAGETABLE_PMD_FOLDED for !LPAE
ARM uses custom implementation of PMD folding in 2-level page table case.
Generic code expects to see __PAGETABLE_PMD_FOLDED to be defined if PMD is
folded, but ARM doesn't do this. Let's fix it.
Defining __PAGETABLE_PMD_FOLDED will drop out unused __pmd_alloc(). It
also fixes problems with recently-introduced pmd accounting on ARM without
LPAE.
