[folded-merged] mm-account-pmd-page-tables-to-the-process-fix-2.patch removed from -mm tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The patch titled
     Subject: mm: add nr_pmds into mm_struct unconditionally
has been removed from the -mm tree.  Its filename was
     mm-account-pmd-page-tables-to-the-process-fix-2.patch

This patch was dropped because it was folded into mm-account-pmd-page-tables-to-the-process.patch

------------------------------------------------------
From: "Kirill A. Shutemov" <kirill.shutemov@xxxxxxxxxxxxxxx>
Subject: mm: add nr_pmds into mm_struct unconditionally

__PAGETABLE_PMD_FOLDED is defined during <asm/pgtable.h> which is not
included into <linux/mm_types.h>.  And we cannot include it here since
many of <asm/pgtables> needs <linux/mm_types.h> to define struct page.

I failed to come up with better solution rather than put nr_pmds into
mm_struct unconditionally.

One possible solution would be to expose number of page table levels
architecture has via Kconfig, but that's ugly and requires changes to
all architectures.
