I got all the files I need for patching the kernel, thanks to your help.
I passed the patch -p0 XXX step without problem. However, during making
disk, I got an anoying message:
gcc: ... ... init/main.o init/main.c
make: *** [init/main.o] Error 1.
There was not file main.o under init/. 
Any suggestion? gcc seems working all right.
