From 9d99aaa31f5994d1923c3713ce9144c4c42332e1 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Fri, 7 Apr 2006 19:49:15 +0200 Subject: [PATCH] x86_64: Support memory hotadd without sparsemem Memory hotadd doesn't need SPARSEMEM, but can be handled by just preallocating mem_maps. This only needs some untangling of ifdefs to enable the necessary code even without SPARSEMEM. Originally from Keith Mannthey, hacked by AK.
