During the init stage, we have only 1 cpu and run with IRQs disabled,
we can't allocate with GFP_KERNEL.
This also fixes the related warning on boot.

Not sure how you get that.

Hrmm. This should not be the case. In early boot GFP_KERNEL
allocations should not trigger a warning when interrupts are
disabled. Which kind of warning are you observing ?

There were two, both pointing at the same WARN(). I don't have the
first one which was fixed in this patch handy, but the second one is:
