The patch titled
Calculation fix for memory holes beyong the end of physical memory
has been removed from the -mm tree. Its filename was
calculation-fix-for-memory-holes-beyong-the-end-of-physical-memory.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: Calculation fix for memory holes beyong the end of physical memory
From: mel@xxxxxxxxx (Mel Gorman)
absent_pages_in_range() made the assumption that users of the
arch-independent zone-sizing API would not care about holes beyound the end
of physical memory. This was not the case and was "fixed" in a patch
called "Account for holes that are outside the range of physical memory".
However, when given a range that started before a hole in "real" memory and
ended beyond the end of memory, it would get the result wrong. The bug is
in mainline but a patch is below.
It has been tested successfully on a number of machines and architectures.
Additional credit to Keith Mannthey for discovering the problem, helping
identify the correct fix and confirming it Worked For Him.
