Subject: [patch 036/147] mm: remove pfn_valid_within() and CONFIG_HOLES_IN_ZONE
Date: Tue, 07 Sep 2021 19:54:52 -0700 [thread overview]
Message-ID: <20210908025452.SQQ0i3M0D%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210907195226.14b1d22a07c085b22968b933@linux-foundation.org>
From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm: remove pfn_valid_within() and CONFIG_HOLES_IN_ZONE
Patch series "mm: remove pfn_valid_within() and CONFIG_HOLES_IN_ZONE".
After recent updates to freeing unused parts of the memory map, no
architecture can have holes in the memory map within a pageblock. This
makes pfn_valid_within() check and CONFIG_HOLES_IN_ZONE configuration
option redundant.
The first patch removes them both in a mechanical way and the second patch
simplifies memory_hotplug::test_pages_in_a_zone() that had
pfn_valid_within() surrounded by more logic than simple if.
This patch (of 2):
After recent changes in freeing of the unused parts of the memory map and
rework of pfn_valid() in arm and arm64 there are no architectures that can
have holes in the memory map within a pageblock and so nothing can enable
CONFIG_HOLES_IN_ZONE which guards non trivial implementation of
pfn_valid_within().
With that, pfn_valid_within() is always hardwired to 1 and can be
completely removed.
Remove calls to pfn_valid_within() and CONFIG_HOLES_IN_ZONE.
