And here's most of the cause: 000002b8 00000124 T early_ioremap 00001000 00001000 t bm_pte 00002000 00000004 T early_ioremap_debug static __initdata pte_t bm_pte[PAGE_SIZE/sizeof(pte_t)] __attribute__((aligned(PAGE_SIZE))); Double ouch. First, this isn't in BSS. Second, even though it's initdata, the alignment slop won't get recovered. Don't we have a special section for page-aligned crap so it doesn't waste most of two pages? -- Mathematics is the supreme nostalgia of our time. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
