I'm getting errors when linking 2.4.20 kernel with grsecurity 1.9.9g on generic RH7.2.
It links well without grsecurity patch. When I turn grsecurity off, it links well too.
One noticable thing is that loadable modules are off and there's a lot options turned on (bzImage would have somthing about 1.2MB).
