Perhaps you may need to re-base to that if Russell is ok with that patch, of course.Nice to see. Ideally test_for_ipi and test_for_ltirq would return early automatically when running SMP kernel on UP. BTW, did you test patch 6284/1 with omap3_defconfig to make sure that still boots on omap3 & 4?Just build tested for all other machines and boot tested on ux500 machine. I do not have omap and other boards :(
OK, I'll give your patch a try on some omap3 board, maybe Santosh can test it on omap4. Regards, Tony
