[PATCH v10 02/18] arm64: hibernate: variable pudp is used instead of pd4dp
From: Pavel Tatashin <pasha.tatashin@soleen.com>
Date: 2021-01-26 10:12:51
Also in:
kexec, linux-mm, lkml
Subsystem:
arm64 port (aarch64 architecture), the rest · Maintainers:
Catalin Marinas, Will Deacon, Linus Torvalds
There should be p4dp used when p4d page is allocated.
This is not a functional issue, but for the logical correctness this
should be fixed.
Fixes: e9f6376858b9 ("arm64: add support for folded p4d page tables")
