Patches for CPU Controller on Control Group v2

===============================================

See Tejun Heo's [explanation][1] for why these patches are currently

out-of-tree.

Generating the patches

-----------------------

In a linux checkout, with remote tc-cgroup pointing to

git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git, your

nixpkgs checkout in the same directory as your linux checkout (or

modify the command accordingly), and setting `ver` to the appropriate

version:

```shell

$ ver=4.7

$ git log --reverse --patch v$ver..remotes/tc-cgroup/cgroup-v2-cpu-v$ver > ../nixpkgs/pkgs/os-specific/linux/kernel/cpu-cgroup-v2-patches/$ver.patch

```
