I'm running some checks now. OK, on ARM with slightly more than an allnoconfig (allnoconfig itself wouldn't build) I see: text data bss dec hex filename 1361476 71360 167320 1600156 186a9c vmlinux.nopm 1364228 71520 167480 1603228 18769c vmlinux 2752 160 160 3072 so 3K from CONFIG_PM there, mostly from the ARM VIC management code which I suspect really wants to be under one of the more specific PM options, though obviously this comes back to the issue with bitrotted ifdefs for PM whcih pervades the kernel. -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
