Subject: [PATCH v5 05/13] mm: Add pud_same similar to __HAVE_ARCH_P4D_SAME
Date: Tue, 18 Jul 2023 07:59:25 +0530	[thread overview]
Message-ID: <20230718022934.90447-6-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20230718022934.90447-1-aneesh.kumar@linux.ibm.com>

This helps architectures to override pmd_same and pud_same independently.
