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.

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.
