The bug looks pretty generic, nothing very PPC-specific there.  It 
might affect other architectures - we won't know until we find out
wht caused it.

well one half of the race looks pretty generic...
..... doesn't mean the other half of the race is though....

Ho hum, I suppose I should pull the patch out of linux-next, to
avoid disrupting other testing.  This means it's going to be hard
to get the bug fixed.

it means losing this one big PPC machine indeed.... until they hit
that same race some other way with regular real cpu hotplug ;-(

So we're kinda stuck with this.  As I can't merge it, I guess I'll make
smp-start-up-non-boot-cpus-asynchronously.patch disappear.

well yeah, PPC is throwing things in the spanner

we're now working on an x86-only patch with basically the same
improvement, but done in a way that does not touch the other architectures

so by all means drop the patch
