Question: Why I need to rebuild all the modules, if they are already builded.
https://wiki.ubuntu.com/KernelTeam/GitKernelBuild
If I make an one line change, I need to wait one hour to make an new
kernel on an intel core duo at 2GHz sistem ?

  you *really* don't want to ask questions like this on LKML or the
ubuntu kernel list.  ask again on the kernelnewbies list and we'll be
happy to explain it.

Depends on which file you change, if that is a header file,
it is supposed to re-compile all the C source files that include it.

Thanks.

make V=2 will tell you what file/config entry caused the rebuild to happen.
