970 and Power4 don't support "continuous sampling" which means that
when we aren't in marked instruction sampling mode (marked events),
SIAR isn't updated with the last instruction sampled before the
perf interrupt. On those processors, we must thus use the exception
SRR0 value as the sampled instr

This makes vio_register_driver() get the module owner & name at compile
time like PCI drivers do, and adds a name pointer directly in struct
vio_driver to avoid having to explicitly initialize the embedded
struct device.

It disturbs all cpus, the -rt people don't like that their FIFO tasks
don't get to run, the trading people don't like their RDMA poll loops to

That makes sense. I'll move them over in my next submission.

This patch changes the architecture vector to advertise support for a
lower minimum virtual processor entitled capacity. The default
minimum without this patch is 10%, this patch specifies 5%. This will
allow 20 LPARs per CPU rather than only 10.

It would be very good to not rely on that though, I would love to get
rid of the stop_machine usage in cpu hotplug some day.
