Looks like a BUG_ON() to me... can you look at what other

Ben, seems like the following patch is causing the cpu hotplug
test failure.
[PATCH 6/6] powerpc/mm: Introduce early_init_mmu() on 64-bit
http://ozlabs.org/pipermail/linuxppc-dev/2009-March/069613.html
If i back out this patch, i am able to offline/online cpu's
without any issue.
I can recreate this problem with 2.6.30-rc2-git1 as well. Same BUG_ON while
running cpu hotplug tests.
Let me know if there is any thing i can help to find a fix for this.
Thanks
