localmodconfig: Document localmodconfig in README (80b810b2) · Commits · 戴 / test

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. Signed-off-by:

		"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.
