Each discrete patch contains a brief description of what it does at the top of the patch itself.

The most significant change is an updated BFS CPU scheduler, up to version 0.363. See the announce of that patch for the changelog. The rest is a resync.

I'll be offline shortly and in Japan for a few weeks so I'll be unlikely to respond to any emails in that time.

Enjoy!

Thanks Con. I can't build a ck kernel without CONFIG_HOTPLUG_CPU but I don't know if this is a bug or a feature :)

Your latest sched_bfs.c encloses the subroutine sched_set_stop_task() inside of an #ifdef CONFIG_HOTPLUG_CPU section.

But the most recent stop_machine.c uses that subroutine twice -- once inside of an #ifdef CONFIG_HOTPLUG_CPU section, and again outside of that section.

The result is that stop_machine.o still needs sched_set_stop_task() even if CONFIG_HOTPLUG_CPU is not defined, so the build fails in the link stage with a missing symbol error.

Thanks for any suggestions/clarifications.
