From fe091c208a40299fba40e62292a610fb91e44b4e Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 8 Dec 2011 10:22:07 -0800 Subject: memblock: Kill memblock_init() memblock_init() initializes arrays for regions and memblock itself; however, all these can be done with struct initializers and memblock_init() can be removed. This patch kills memblock_init() and initializes memblock with struct initializer. The only difference is that the first dummy entries don't have .nid set to MAX_NUMNODES initially. This doesn't cause any behavior difference. Signed-off-by: Tejun Heo Cc: Benjamin Herrenschmidt Cc: Yinghai Lu Cc: Russell King Cc: Michal Simek Cc: Paul Mundt Cc: "David S.
