It is NOT a comment. That line is read during the build procedure for
identification of the arch.
# now run oldconfig over all the config files
for i in *.config
mv $i .config
Arch=`head -1 .config | cut -b 3-`
make ARCH=$Arch nonint_oldconfig > /dev/null

cat .config >> configs/$i

You need to add the patch file to the SOURCES directory and edit the
.spec file to include that patch. This is explained in the wiki
