The earlier versions can be found at http://lkml.org/lkml/2007/10/24/36 and http://lkml.org/lkml/2007/10/16/118. This version drops the patch 4 from the earlier series, which was basically removing the CPU_DEAD and CPU_UP_CANCELLED event handling in the workqueue subsystem. This was based on Oleg Nestertov's comments since the problem which the patch was attempting to solve was more complicated and needs to be looked into seperately. The patch series is against v2.6.24-rc2 and has survived overnight kern_bench + cpu-offline-online tests on - 8 way x86, - 8 way x86_64, - 128 way ppc64 boxes. The patch series has gone through many iterations and looks to have matured in the process. Andrew, could you please consider it for the next -mm release if there are no objections ?
