The option code is tricky as it is used by standalone code. If you include that file and you are standalone, you now have to define STANDALONE (is there a better way?) Change the cpuid to be a 24-byte string instead of 3 u32s. Make the CPUID usage PIC-safe by not using %ebx. Test building on two different geodes, tested to boot on dbe62 Signed-off-by: Ronald G.
