From 860a1aa2ec8195a4ddb09104f3148961a9f1a0af Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Fri, 27 Jul 2007 15:43:42 -0400 Subject: [PATCH] OOM: use the 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.
