I'm afraid a lot of this, like the CPUID changes, are fairly pointless because they are __cpuinit code anyways. This means (unless you compiled a kernel with CPU hotplug support enabled) it will be all freed after boot. > Already with these patches I can compile a zImage kernel that is 450kb > large (890kb decompressed) The important part is not how big the vmlinux is, but how much memory is actually used after boot. I expect concentrating some of the dynamic data structures would be more fruitful in fact. -Andi - 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/
