Subject: [PATCH v2 2/5] mm/pgtable: Add stubs for {pmd/pub}_{set/clear}_huge
Date: Wed, 12 May 2021 05:00:59 +0000 (UTC)	[thread overview]
Message-ID: <5ac5976419350e8e048d463a64cae449eb3ba4b0.1620795204.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1620795204.git.christophe.leroy@csgroup.eu>

For architectures with no PMD and/or no PUD, add stubs
similar to what we have for architectures without P4D.
