Yep. commit 1be6f10f6f9caade3a053938cb80a2eed237e262 Author: Michael Ellerman <mpe@xxxxxxxxxxxxxx> Date: Mon Dec 29 15:47:05 2014 +1100 Revert "powerpc: Secondary CPUs must set cpu_callin_map after setting active and online" This reverts commit 7c5c92ed56d932b2c19c3f8aea86369509407d33. Although this did fix the bug it was aimed at, it also broke secondary startup on platforms that use give/take_timebase(). Unfortunately we didn't detect that while it was in next. Signed-off-by: Michael Ellerman <mpe@xxxxxxxxxxxxxx> Is there a better way to handle that? ie. should we have CC'ed the revert to stable? cheers -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
