The on-demand code is permanently disabled using static branching once
deferred pages are initialized. After the static branch is changed to
false, the overhead is up-to two branch-always instructions if the zone
watermark check fails or if rmqueue fails.

fix alignment, here the trampoline binary is later copied
into dynamically allocated memory in reserve_real_mode(), so we need to
fix that place as well.

The poisoning helps to catch these now, and will in the future.
Because we are setting "struct page" to all 1s, we get nid that is
