Subject: [PATCH v4 05/13] mm: Add __HAVE_ARCH_PUD_SAME similar to __HAVE_ARCH_P4D_SAME
Date: Mon, 10 Jul 2023 21:38:34 +0530 [thread overview]
Message-ID: <20230710160842.56300-6-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20230710160842.56300-1-aneesh.kumar@linux.ibm.com>
This helps architectures to override pmd_same and pud_same independently.
