de1b28989e drm/radeon/kms: cut down indirects in register accesses. 
We really don't want to be doing all these indirects, updating
the GPU gart table is something we do often so the less overhead the
better.

8064d54929 rcu: Make preemptable RCU scan all CPUs when summing RCU counters 
This patch eliminates the counter-moving during CPU-offline
notifiers, eliminating potential confusion if counters are
scanned during counter-movement process.

This confusion could result in premature ending of an RCU grace
period. For example, if there are two tasks in RCU read-side
critical sections (so that the sum of the counters is two), and
the counter for the CPU going offline is -2, then moving the
count to another CPU can result in the sum momentarily
appearing to be zero.  Since there are no memory barriers in
either case, many more such scenarios are possible.

So just don't move the counts!!!

2e59755808 rcu: Simplify RCU CPU-hotplug notification 
Use the new cpu_notifier() API to simplify RCU's CPU-hotplug
notifiers, collapsing down to a single such notifier.

This makes it trivial to provide the notifier-ordering
guarantee that rcu_barrier() depends on.

Also remove redundant open_softirq() calls from Hierarchical
RCU notifier.

799e64f05f cpu hotplug: Introduce cpu_notifier() to handle !HOTPLUG_CPU case 
This patch introduces a new cpu_notifier() API that is similar
to hotcpu_notifier(), but which also notifies of CPUs coming

27569620c7 rcu: Split hierarchical RCU initialization into boot-time and CPU-online pieces 
This patch divides the rcutree initialization into boot-time
and hotplug-time components, so that the tree data structures
are guaranteed to be fully linked at boot time regardless of
what might happen in CPU hotplug operations.

This makes RCU more resilient against CPU hotplug misbehavior
(and vice versa), but more importantly, does a better job of
compartmentalizing the code.
