Subject: [PATCH 3/4] mm: mremap: use flush_pud_tlb_range in move_normal_pud()
Date: Mon, 31 Jul 2023 15:48:28 +0800 [thread overview]
Message-ID: <20230731074829.79309-4-wangkefeng.wang@huawei.com> (raw)
In-Reply-To: <20230731074829.79309-1-wangkefeng.wang@huawei.com>
Archs may need to do special things when flushing thp tlb,
so use the more applicable flush_pud_tlb_range() instead of
flush_tlb_range().
Fixes: c49dd3401802 ("mm: speedup mremap on 1GB or larger regions")
