Subject: + mm-consolidate-pmd_index-and-pmd_offset-definitions.patch added to -mm tree
Date: Fri, 15 May 2020 14:16:04 -0700 [thread overview]
Message-ID: <20200515211604.8wMCYIeH0%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200513175005.1f4839360c18c0238df292d1@linux-foundation.org>
The patch titled
Subject: mm: consolidate pmd_index() and pmd_offset() definitions
has been added to the -mm tree. Its filename is
mm-consolidate-pmd_index-and-pmd_offset-definitions.patch
This patch should soon appear at
http://ozlabs.org/~akpm/mmots/broken-out/mm-consolidate-pmd_index-and-pmd_offset-definitions.patch
and later at
http://ozlabs.org/~akpm/mmotm/broken-out/mm-consolidate-pmd_index-and-pmd_offset-definitions.patch
Before you just go and hit "reply", please:
a) Consider who else should be cc'ed
b) Prefer to cc a suitable mailing list as well
c) Ideally: find the original patch on the mailing list and do a
reply-to-all to that, adding suitable additional cc's
*** Remember to use Documentation/process/submit-checklist.rst when testing your code ***
The -mm tree is included into linux-next and is updated
there every 3-4 working days

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm: consolidate pmd_index() and pmd_offset() definitions
All architectures define pmd_index() as
(address >> PMD_SHIFT) & (PTRS_PER_PMD - 1)
and all architectures that have at least three-level page tables define
pmd_offset() as an entry in the array of PMDs indexed by the pmd_index().
For the most architectures the pmd_offset() implementation relies on the
availability of pud_page_vaddr() that converts a PMD entry value to the
virtual address of the page containing PMD array.
Let's use such implementation as a generic and drop most of the
definitions of pmd_index() and pmd_offset() in <asm/pgtable.h> files.
The architectures that didn't provide pud_page_vaddr() are updated to have
that defined.
The generic implementation can be overridden by an architecture and this
ability is currently in use by there architectures:
* alpha has special requirements for memory access ordering
* arm has custom definition of folded 2-level page tables
* s390 has custom definitions of all page table accessors
