From d8f10cb3d375c34ad668f32ca6e4661ad1fc23b2 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Mon, 29 Apr 2013 15:08:08 -0700 Subject: [PATCH] kernel/cpuset.c: use register_hotmemory_notifier() Use the new interface, remove one ifdef. No code size changes. We could/should have been using __meminit/__meminitdata here but there's now no point in doing that because all this code is elided at compile time.
