Subject: [PATCH 0/2] arm64/mm: Enable THP migration
Date: Mon, 17 Aug 2020 14:49:42 +0530 [thread overview]
Message-ID: <1597655984-15428-1-git-send-email-anshuman.khandual@arm.com> (raw)
This series enables THP migration on arm64 via ARCH_ENABLE_THP_MIGRATION.
But first this modifies all existing THP helpers like pmd_present() and
pmd_trans_huge() etc per expected generic memory semantics as concluded
from a previous discussion here.
https://lkml.org/lkml/2018/10/9/220
This series is based on v5.9-rc1.
Changes in V1:
- Used new PMD_PRESENT_INVALID (bit 59) to represent invalidated PMD state per Catalin
Changes in RFC V2: (https://patchwork.kernel.org/project/linux-mm/list/?series=302965)
- Used PMD_TABLE_BIT to represent splitting PMD state per Catalin
Changes in RFC V1: (https://patchwork.kernel.org/project/linux-mm/list/?series=138797)
