    Subject[PATCH 6.0 215/862] ARM: 9244/1: dump: Fix wrong pg_level in walk_pmd()
    Date
    From: Wang Kefeng <wangkefeng.wang@huawei.com>

    [ Upstream commit 2ccd19b3ffac07cc7e75a2bd1ed779728bb67197 ]

    After ARM supports p4d page tables, the pg_level for note_page()
    in walk_pmd() should be 4, not 3, fix it.

    Fixes: 84e6ffb2c49c ("arm: add support for folded p4d page tables")
