I believe this is 'good'. The discrepancies between the roll and control are:

linux
   roll:    
            browser_tests failed 3
                PromptForXHRSubmit *******************************************
                WebContentsHasFocus
                ArgumentValidation *******************************************
   control: 
            net_unittests 27 disabled did not complete failed 1
                BigDirRecursiveTest
            browser_tests failed 1
                WebContentsHasFocus

win_gpu - this bot is still broken as in previous roll attempts
   roll:    
            content_browsertests - timed out
   control: 
            content_browsertests failed 110    
                MANUAL_conformance*  

mac_layout_rel
   roll:    
            webkit_tests 1593 fixable (0 skipped) failed 9
                select-missing-image.html
                002.html
                017.html
                023.html
                024.html
                005.html
                012.html
                comment-in-script.html
                bug2997.html
            - all of these appeared in both the roll and control for
              mac_layout
   control: 
            compile failed
