I just checked for you: Old 2.6.16 powerpc 32 kernel: text data bss dec hex filename 2399368 222224 156124 2777716 2a6274 build/vmlinux 2394634 221804 156124 2772562 2a4e52 build-nhp/vmlinux That looks like around 5154 bytes to me New 3.6 powerpc 32 kernel: text data bss dec hex filename 3352356 162812 218132 3733300 38f734 build/vmlinux 3347644 162648 217860 3728152 38e318 build-nhp/vmlinux And that is about 5148 bytes. In both cases the only difference is adding CONFIG_HOTPLUG=y to the config. 5k isn't a lot, but in the context of 'I have to figure out how to trim ~1MB off the 3.6 kernel to run it in our smallest hardware' it is the wrong direction :( Regards, Jason -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
