How to build a PowerPC kernel image and rootfs containing systemtap

[a798047815]

Thanks for your excellent work, I have learned a lot about dynamic analysis of IoT software.
I wanna build a PowerPC image and rootfs.ext2 with systemtap module file like you did already.
Now I know that I must generate .ko file by following your another repo:csb

But I'm ... truly new to this.
Can you give me some more detailed guides on how to build the kernel containing systemtap?
So then I can use this kernel to generate systemtap module file(.ko) and put it into the rootfs?

Thanks a lot!
