Subject: [PATCH 0/2] arm64/mm: Fix pfn_valid() for ZONE_DEVICE based memory
Date: Fri, 29 Jan 2021 13:09:44 +0530 [thread overview]
Message-ID: <1611905986-20155-1-git-send-email-anshuman.khandual@arm.com> (raw)
This series fixes pfn_valid() for ZONE_DEVICE based memory and also improves
its performance for normal hotplug memory. While here, it also reorganizes
pfn_valid() on CONFIG_SPARSEMEM. This series is based on v5.11-rc5.
Question - should pfn_section_valid() be tested both for boot and non boot
memory as well ?
