We give up old_addr hint from the coming patch module in cases when kernel load base has been randomized (as in such case, the coming module has no idea about the exact randomization offset). We are currently too pessimistic, and give up immediately as soon as CONFIG_RANDOMIZE_BASE is set; this doesn't however directly imply that the load base has actually been randomized. There are config options that disable kASLR (such as hibernation), user could have disabled kaslr on kernel command-line, etc. The loader propagates the information whether kernel has been randomized through bootparams. This allows us to have the condition more accurate. On top of that, it seems unnecessary to give up old_addr hints even if randomization is active. The relocation offset can be computed using kaslr_ofsset(), and therefore old_addr can be adjusted accordingly.
