Drop it for the moment.
My expectation is that it's a relatively minor hazard. The removal of the
fair zone allocation policy is a shorter path which benefits a number
of workloads but also potentially changes the color of pages used in
microbenchmarks which can have a cache effect. It's on my TODO list to
reproduce this exactly as LKP does but my own preliminary experiments using
pbzip (yes, it's different) on 4 machines showed gains on all 4 machines
so something relatively subtle is going on or it's machine specific.
