I'm not sure there is a real problem, I thought Michael was just

In addition, it seems that svm_page_enc_status_hc() accepts 'gpa',
'npages', 'enc' directly from the guest, and so these can take

The current implementation of the CPU controller uses hierarchical
runqueues, where on wakeup a task is enqueued on its group's runqueue,
the group is enqueued on the runqueue of the group above it, etc.
This increases a fairly large amount of overhead for workloads that
do a lot of wakeups a seco

The runnable_load magic is used to quickly propagate information about
runnable tasks up the hierarchy of runqueues. The runnable_load_avg is
mostly used for the load balancing code, which only examines the value at
the root cfs_rq.
Redefine the root cfs_rq runnable_load_avg to be the sum of task_
Add helper functions to make the flattened runqueue patch a little smaller.
The task_se_h_weight function is similar to task_se_h_load, but scales the
task weight by the group weight, without taking the task's duty cycle into
account.
The task_se_in_cgroup helper is functionally identical to pare
The way the time slice length is currently calculated, not only do high
priority tasks get longer time slices than low priority tasks, but due
to fixed point math, low priority tasks could end up with a zero length
time slice. This can lead to cache thrashing and other inefficiencies.
Cap the mini
Since only the root cfs_rq runnable_load_avg field is used any more,
we can move the field from struct sched_avg, which every sched_entity
has one of, directly into the struct cfs_rq, of which we have way fewer.
No functional changes.
