Modify kernel steps
put the following in .rpmmacros:
cat ~/.rpmmacros
%_topdir %(echo /home/user/mypath)/rpm
%_tmppath %(echo /home/user/mypath)/rpm/tmp
%debug_package %{nil}

• install the src package

  rpm -i kernel*.src.rpm

• generate patches and put in SOURCES
• modified kernel*.config in SOURCES
• modified SPEC/kernel*.spec to pickup the patches
  Patch3000: my.patch
  %patch3000 -p1

apply the patch (cd to SPECS)

rpmbuild -bp --target=i686 kernel-2.6.spec

build:

rpmbuild -bb --with baseonly --without debug --without debuginfo --without kabichk --target=i686 kernel-2.6.spec

use buildid to change buildname
build without rpm

rpmbuild -bp kernelsrc.rpm
cd rpm/kernel/sourcedir
