nt 057647fc47b3a5fbcfa997041db3f483d506603c author Mel Gorman 1162057139 -0700 committer Linus Torvalds 1162060255 -0700 [PATCH] Calculation fix for memory holes beyong the end of physical memory 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.
