Yinghai Lu b7ad149d62 x86: reenable support for system without on node0 
One system doesn't have RAM for node0 installed.

SRAT: PXM 0 -> APIC 0 -> Node 0
SRAT: PXM 0 -> APIC 1 -> Node 0
SRAT: PXM 1 -> APIC 2 -> Node 1
SRAT: PXM 1 -> APIC 3 -> Node 1
SRAT: Node 1 PXM 1 0-a0000
SRAT: Node 1 PXM 1 0-dd000000
SRAT: Node 1 PXM 1 0-123000000
ACPI: SLIT: nodes = 2

Could not find start_pfn for node 0
Pid: 0, comm: swapper Not tainted 2.6.24-smp-g5a514e21-dirty #14

Call Trace:

 [<ffffffff80b971cc>] _sinittext+0x1cc/0x1d3

This happens because node 0 is not online, but the node state in
mm/page_alloc.c has node 0 set.

        nodemask_t node_states[NR_NODE_STATES] __read_mostly = {
                [N_POSSIBLE] = NODE_MASK_ALL,
                [N_ONLINE] = { { [0] = 1UL } },

So we need to clear node_online_map before initializing the memory.
