Looks like I didn't express myself too clearly: the early version of
early_pgtable_l5_enabled() should use a simple variable like now - not
cpu_feature_enabled().

And regardless, cpu_feature_enabled() should work even before
alternatives have run because we do dynamic testing in that case... and
so on and so on.

BUT(!), let's put a pin in this and let me first have an indepth look
after the merge window so that I can poke at the details and produce
a concrete diff which we can talk about.

Thx.
