Or you would like to pass some info from the compressed kernel to kernel proper?
For example, something like the passing in add_e820ext() and the consumtion in parse_setup_data():
switch (data_type) { case SETUP_E820_EXT: e820__memory_setup_extended(pa_data, data_len);
So info you need for your padding gets collected in arch/x86/boot/compressed/acpitb.c and you consume it in kernel_randomize_memory()?
Would that work?
:-)
