[PATCH] x86: make sure memory block is RAM before passing to the allocator
Memory blocks outside of the always visible 1:1 mapping range get
passed to the allocator separately (once enough other setup was done).
Skipping non-RAM regions, however, was forgotten in adc5afbf ("x86:
support up to 16Tb").
