Subject: [PATCH v4 1/6] mm/hotplug: Simplify ARCH_MHP_MEMMAP_ON_MEMORY_ENABLE kconfig
Date: Tue, 18 Jul 2023 08:14:04 +0530 [thread overview]
Message-ID: <20230718024409.95742-2-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20230718024409.95742-1-aneesh.kumar@linux.ibm.com>
Instead of adding menu entry with all supported architectures, add
mm/Kconfig variable and select the same from supported architectures.
No functional change in this patch.
Acked-by: David Hildenbrand <david@redhat.com>
