[ Upstream commit c7206e7bd2 ]
There are many types of revsered memory passed from firmware
that should be reserved in memblock, and UMA memory passed
from firmware that should be added to system memory for system
to use.
Also for memblock there is no need to align those space into page,
which actually cause problems.
Handle them properly to prevent memory corruption on some systems.
