The current code fails to print the "[heap]" marking if the heap is
splitted into multiple mappings.

Fix the check so that the marking is displayed in all possible cases:
	1. vma matches exactly the heap
	2. the heap vma is merged e.g. with bss
	3. the heap vma is splitted e.g. due to locked pages

Why do you believe this problem is serious enough to justify
backporting the fix into -stable?

My bad analysis. It looks like the bug has been there forever, and
since it only results in some information missing from a procfile,
it does not fulfil the stable "critical issue" criteria.
