There appears to be an issue in using \small in certain cases on Sphinx
1.4 and 1.5. Other format documents don't use \small either, remove it
from here as well.

This is just a resend of Waiman Long's patch.
I could not find why it was not merged to upstream, so I thought
to give it another chance.
What follows is what Waiman Long wrote.
Xen has an kernel command line argument "xen_nopvspin" to disable
paravirtual spinlocks. This patch adds a similar "kvm_

Traditionally, the OOM killer is operating on a process level.
Under oom conditions, it finds a process with the highest oom score
and kills it.
This behavior doesn't suit well the system with many running
containers:

The oom_kill_process() function consists of two logical parts:
the first one is responsible for considering task's children as
a potential victim and printing the debug information.
The second half is responsible for sending SIGKILL to all
tasks sharing the mm struct with the given victim.

This patchset makes the OOM killer cgroup-aware.
v7:
- __oom_kill_process() drops reference to the victim task
- oom_score_adj -1000 is always respected
- Renamed oom_kill_all to oom_group

- Added a cgroup v2 mount option to disable c
Introduce a per-memory-cgroup oom_priority setting: an integer number,
which defines the order in which the OOM killer selects victim memory
cgroups.
OOM killer prefers memory cgroups with larger priority if they are

Introducing of cgroup-aware OOM killer changes the victim selection

it will pick the largest memcg and then the largest process inside.
This affects only cgroup v2 users.

Usually, CA messages are sent/received via reading/writing at
the CA device node. However, two drivers (dst_ca and firedtv-ci)
also implement it via ioctls.
Apparently, on both cases, the net result is the same.
Anyway, let's document it.

Thanks to some discussions I had with Honza, I got some ideas about how to
document the last three undocumented ioctls from ca.h, together with the
two data structures.
With this series (and the previous one), everything at CA, Net, Demux
and DVBv5 Frontend DVB APIs are now documented. That's IMH
