kernel.clean

make a clean build for linux kernel

1: generate the defconfig
-- config from from rpm extract files. not from x86/configs/

2:  clean unused files
-- rm arch subdirectory except x86
-- remove Documentation from root Makefile
   rm Documentation except Makefile
-- rm readme etc.
-- rm .gitignore  
 
 mv  .gitignore   11
find  . -name ".gitignore" | xargs rm -f 
mv 11 .gitignore

 
3:  git init / git add / git commit /git clean -dfx

4: make menuconfig
-- remove firmware 
-- remove sound
-- remove virtualization
-- remove drivers 

-- new .config to x86_64_defconfig
