yes, I know about mem=xx. What i dont know is: what is maximum memory left
for vmlinuz to use.

for exmple:
i have 128mb of memory in PC.
L4 uses: Xmb
vmlinuz can use 128mb - Xmb = Ymb

I tried giving "mem=64" option but (i think DOpE) says it cannot assign
64mb to vmlinux. option "mem=50" worked. I don't think it's just a "try
and see" method, there must be some other way.

So new Linux needs another root, swap... seems logical.
