Subject[PATCH 0/2] Add bounds check for Hotplugged memory
Date
From: Alastair D'Silva <alastair@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.

Alastair D'Silva (2):
memory_hotplug: Add a bounds check to check_hotplug_memory_range()
mm: Add a bounds check in devm_memremap_pages()
