From ee31af5d649d8aa6ac7948a6d97ae48367ff2d7e Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Tue, 16 Oct 2007 01:25:30 -0700 Subject: [PATCH] Memoryless nodes: OOM: use N_HIGH_MEMORY map instead of constructing one on the fly constrained_alloc() builds its own memory map for nodes with memory. We have that available in N_HIGH_MEMORY now. So simplify the code.
