sparsemem: ensure we initialise the node mapping for SPARSEMEM_STATIC
Booting SPARSEMEM on NUMA systems trips a BUG in page_alloc.c: Initializing HighMem for node 0 (00038000:00100000) Initializing HighMem for node 1 (00100000:001ffe00) ------------[ cut here ]------------ kernel BUG at /home/apw/git/linux-2.6/mm/page_alloc.c:456! [...] This occurs because the section to node id mapping is not being setup correctly during init under SPARSEMEM_STATIC, leading to an attempt to free pages from all nodes into the zones on node 0. When the zone_table[] was removed in the following commit, a new section to node mapping table was introduced: commit 89689ae7f95995723fbcd5c116c47933a3bb8b13 [PATCH] Get rid of zone_table[] That conversion inadvertantly only initialised the node mapping in SPARSEMEM_EXTREME. Ensure we initialise the node mapping in SPARSEMEM_STATIC.
