If you want to be masochistic, you can always: 'make allyesconfig' before

idea of the longest it could take to build a kernel.

Ok, that's one humongous kernel:

  $ size vmlinux
        text       data     bss     dec     hex filename
     31146564   4885797 6758472 42790833        28cefb1 vmlinux

Yes, that's a 31MB kernel.  The file itself is 311MB.

The build took just over 20 minutes.  I have two CPUs, so a single-cpu
compiling absolutely everything would probably be about 40 minutes
(probably a little less).
