From: Alastair D'Silva <alast...@d-silva.org> This series adds bounds checks for hotplugged memory, ensuring that it is within the physically addressable range (for platforms that define MAX_(POSSIBLE_)PHYSMEM_BITS.
This allows for early failure, rather than attempting to access bogus section numbers.
