Instead of specifying the preemption granularity, specify the wanted
latency. By fixing the granlarity to a constany the wakeup latency
it a function of the number of running tasks on the rq.
Invert this relation.
sysctl_sched_granularity becomes a minimum for the dynamic granularity
computed from the new sysctl_sched_latency.
Then use this latency to do more intelligent granularity decisions: if
there are fewer tasks running then we can schedule coarser. This helps
performance while still always keeping the latency target.

This handles the case where we get the status write before getting the
complete_transaction callback ("status write for unknown orb"). In
this case, we just assume that the initial orb pointer transaction
succeeded and finish the orb. To prevent the transaction callback
from touching freed memory, we ref-count the orb structures.

This partially reverts edd0622bd2.
It turns out that the part of that commit that aimed to ensure that we
created an SLB entry for the kernel stack on secondary CPUs when
starting the CPU didn't achieve its aim, and in fact caused a
regression, because get_paca()->kstack is not initialized at the point
where slb_initialize is called.
This therefore just reverts that part of that commit, while keeping
the change to slb_flush_and_rebolt, which is correct and necessary.

Firmware would not deliver two interrupt numbers in device-tree any more
but only one, for correctable ECC, because uncorrectable ECC from now
is handled by firmware itself.
Changes in the axonram module are necessary because in the old version, if
it is not allowed to fetch the second interrupt number from device-tree,
it interpretes this as an error case and exits.

The Cell Broadband Engine has a method of injecting a
system-reset-exception from an external source into the
operating system, which should trigger the regular behaviour
of entering xmon or kdump.
Unfortunately, the exception handler cannot distinguish it from
other interrupt causes by the SRR1 register, which gets used
for this on Power 6 and others.
IBM Blade servers that want to support triggering the
system reset exception using a pinhole button in the front
panel therefore use an extra register to determine the
reset cause.

Legacy device tree used the reg property for the physical id of an
spe. On newer device tree layouts the reg property contains the
"correct" value in the reg attribute. So there has been intoduced the
"physical-id" on newer devicetree layouts. The id is stored by
spu_manage into the spu struct as spe_id. cbe_thermal has been
changed to use the spu->spe_id. There's no need for the thermal code
to check devicetree attributes for itself.

count interface. Reading and setting those values doesn't take place
"manually", instead wrapping functions are called to allow quirks for some
