From ab3818432294a19ad793a0965d89867b4ce6255b Mon Sep 17 00:00:00 2001 From: Johannes Weiner Date: Tue, 29 May 2012 15:06:34 -0700 Subject: [PATCH] mm: bootmem: allocate in order node+goal, goal, node, anywhere Match the nobootmem version of __alloc_bootmem_node. Try to satisfy both the node and the goal, then just the goal, then just the node, then allocate anywhere before panicking. Signed-off-by: Johannes Weiner Acked-by: Tejun Heo Acked-by: David S.
