[PATCH 0/2] Add bounds check for Hotplugged memory

["Alastair D'Silva" <alastair@xxxxxxxxxxx>]

From: Alastair D'Silva <alastair@xxxxxxxxxxx>

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()
