From cddb8d09ff1e477de8236a061a5017b21bab3c14 Mon Sep 17 00:00:00 2001 From: Liu Shixin Date: Fri, 23 Sep 2022 11:33:43 +0800 Subject: mm/mmap: use hotplug_memory_notifier() directly Commit 76ae847497bc52 ("Documentation: raise minimum supported version of GCC to 5.1") updated the minimum gcc version to 5.1. So the problem mentioned in f02c69680088 ("include/linux/memory.h: implement register_hotmemory_notifier()") no longer exist. So we can now switch to use hotplug_memory_notifier() directly rather than register_hotmemory_notifier().
