Got it, thanks.

Yes, but I think we need to arrange the Chao's SRAT parsing to be used
from kernel_randomize_memory() because Chao's approach needs the SRAT
parsing before extract kernel and the padding size calculation needs
the parsing in start_kernel(), so they are living in different life
cycle and space.

Thanks,
