From 148f1678f0ba7a5e79e44ff23064d4326fa145a4 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Tue, 10 Jun 2008 10:03:18 +0200 Subject: [S390] sparsemem: use SPARSEMEM_STATIC if !64BIT. In case of !64BIT kernel we end up with a zero sized mem_section array. This happens because NR_MEM_SECTIONS is smaller than SECTIONS_PER_ROOT but we have: #define NR_SECTION_ROOTS (NR_MEM_SECTIONS / SECTIONS_PER_ROOT) and struct mem_section *mem_section[NR_SECTION_ROOTS]; So fix this by selecting SPARSEMEM_STATIC which makes sure that SECTIONS_PER_ROOT is 1.
