v3:	- Sync with linux-next where arch_get_mappable_range() was
	  introduced.
v2:	- Added test-by Tyler Hicks
	- Addressed comments from Anshuman Khandual: moved check under
	  IS_ENABLED(CONFIG_RANDOMIZE_BASE), added 
	  WARN_ON(start_linear_pa > end_linear_pa);

Fixes a hotplug error that may occur on systems with CONFIG_RANDOMIZE_BASE
enabled.

Applies against linux-next.

v1:
