metag: Drop show_mem() from mem_init()
The recent commit 599d0c954f91 ("mm, vmscan: move LRU lists to node"), changed memory management code so that show_mem() is no longer safe to call prior to setup_per_cpu_pageset(), as pgdat->per_cpu_nodestats will still be NULL. This causes an oops on metag due to the call to show_mem() from mem_init(): node_page_state_snapshot(...) + 0x48 pgdat_reclaimable(struct pglist_data * pgdat = 0x402517a0) show_free_areas(unsigned int filter = 0) + 0x2cc show_mem(unsigned int filter = 0) + 0x18 mem_init() mm_init() start_kernel() + 0x204 This wasn't a problem before with zone_reclaimable() as zone_pcp_init() was already setting zone->pageset to &boot_pageset, via setup_arch() and paging_init(), which happens before mm_init(): zone_pcp_init(...) free_area_init_core(...) + 0x138 free_area_init_node(int nid = 0, ...) + 0x1a0 free_area_init_nodes(...) + 0x440 paging_init(unsigned long mem_end = 0x4fe00000) + 0x378 setup_arch(char ** cmdline_p = 0x4024e038) + 0x2b8 start_kernel() + 0x54 No other arches appear to call show_mem() during boot, and it doesn't really add much value to the log, so lets just drop it from mem_init().
