关于用2.6内核作lfs，glibc-kernheaders-* files一点我不明白

一文中指出
get: http://download.fedora.redhat.co ... e/development/SRPMS
you will need the glibc-kernheaders-* file.

..........
Chapter 6 -- Installing sanitized kernel headers
After you install the glibc you should do this.
        tar jxvf glibc-kernelheaders.tar.bz2
        cd usr/include
        ***NOTE*** if your arch is something other then i386 then you
should change the next line to fit. EX. asm-ppc, to see all possible
ones just ls. :-p       
        cp -R asm-i386 /usr/include/asm   
        cp -R linux /usr/include


这些头文件与glibc或kernel代码树中的不同么？
