localmodconfig: Document localmodconfig in README 



Someone (over a year ago :-p) asked me to document localmodconfig in the
README file in the source code.  I thought it was a good idea but other
things were more important and I simply forgot about it.  Well, I
stumbled on the email asking me about this and I'm sending it out now.

     "make randconfig"  Create a ./.config file by setting symbol

                        values to random values.



     "make localmodconfig" Create a config based on current config and

                           loaded modules (lsmod). Disables any module

                           option that is not needed for the loaded modules.



                           To create a localmodconfig for another machine,

                           store the lsmod of that machine into a file

                           and pass it in as a LSMOD parameter.



                   target$ lsmod > /tmp/mylsmod

                   target$ scp /tmp/mylsmod host:/tmp



                   host$ make LSMOD=/tmp/mylsmod localmodconfig



                           The above also works when cross compiling.



     "make localyesconfig" Similar to localmodconfig, except it will convert

                           all module options to built in (=y) options.



   You can find more information on using the Linux kernel config tools

   in Documentation/kbuild/kconfig.txt.
