Peter Anvin | CommitDate: Thu May 7 21:51:34 2009 -0700 | | x86-64: finish cleanup_highmaps()'s job wrt. _brk_end | ... i.e. the bug is almost 2 years and 8 -stable cycles old! Peter very consciously did not mark the fix for this commit as -stable material. It was ineligible for -stable for multiple reasons: it by no means fixed a 2.6.39 regression and the fix was literally just a few days old. Thanks, Ingo
