From e3c2bfdd33a30b34674fb8839f5476ab2702c1c1 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Tue, 8 Aug 2023 14:44:57 +0530 Subject: mm/memory_hotplug: allow memmap on memory hotplug request to fallback If not supported, fallback to not using memap on memmory. This avoids the need for callers to do the fallback.
