Revision ddc1729b07cc84bb29f577698b8d2e74a4004a6e authored by Hongchen Zhang on 15 June 2023, 06:35:52 UTC, committed by Huacai Chen on 15 June 2023, 06:35:52 UTC
When we split a pmd into ptes, pmd_present() and pmd_trans_huge() should
return true, otherwise it would be treated as a swap pmd.
This is the same as arm64 does in commit b65399f6111b ("arm64/mm: Change
THP helpers to comply with generic MM semantics"), we also add a new bit
named _PAGE_PRESENT_INVALID for LoongArch.
