I tested your tree till this patch set under our lkp testing system, with benchmark kbuild, aim9-mutitask, specjbb2005 -openjdk/jrockit, hackbench-process/thread, sysbench -fileio-cfq, multiple loop back netperf, on 2 laptops, SNB i7, and WSM i5. only aim9-mutitask-nl (2000 loads, increment 100) has about 2% performance drop on both of machine. all others has no clear performance change. > enable this by default (and it does have 'default y', which is a big > no-no for new features - I undid that part) then there will be tons of > people running this without actually having multiple sockets.
