Sincerly, Thomas --- Turn CONFIG_DMI into a selectable option if EMBEDDED is defined, in order to be able to remove the DMI table scanning code if it's not needed, and then reduce the kernel code size. With CONFIG_DMI (i.e before) : text data bss dec hex filename 1076076 128656 98304 1303036 13e1fc vmlinux Without CONFIG_DMI (i.e after) : text data bss dec hex filename 1068092 126308 98304 1292704 13b9a0 vmlinux Result: text data bss dec hex filename -7984 -2348 0 -10332 -285c vmlinux The new option appears in "Processor type and features", only when CONFIG_EMBEDDED is defined. This patch is part of the Linux Tiny project, and is based on previous work done by Matt Mackall .
