Subject: [PATCH V3 0/2] arm64/mm: Fix pfn_valid() for ZONE_DEVICE based memory
Date: Fri, 5 Mar 2021 10:54:56 +0530 [thread overview]
Message-ID: <1614921898-4099-1-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 v5.12-rc1.

Changes in V3:
- Validate the pfn before fetching mem_section with __pfn_to_section() in [PATCH 2/2]
Changes in V2:
https://lore.kernel.org/linux-mm/1612239114-28428-1-git-send-email-anshuman.khandual@arm.com/
- Dropped pfn_valid() bifurcation based on CONFIG_SPARSEMEM
- Used PFN_PHYS() and PHYS_PFN() instead of __pfn_to_phys() and __phys_to_pfn()
- Moved __pfn_to_section() inside #ifdef CONFIG_SPARSEMEM with a { } construct
Changes in V1:
https://lore.kernel.org/linux-mm/1611905986-20155-1-git-send-email-anshuman.khandual@arm.com/
- Test pfn_section_valid() for non boot memory
