Plugin scheduler now can do cores isolation on its own, Tuna is
not needed for it, e.g.:
[scheduler]
isolated_cores=2-4
ps_blacklist=.*pmd.*;.*PMD.*;^DPDK;.*qemu-kvm.*
It will isolate cores 2-4, it will ignore processes which matched
ps_blacklist regexes. Multiple regexes can be separated by ';'.
Quoted semicolon, i.e. '\;' is taken literally.
It also supports 'ps_whitelist' which is by default set to '.*'.
It takes all processes which matches ps_whitelist than it removes
those which matches ps_blacklist and move them out of the
isolated_cores. When the profile is unloaded it allows all matching
processes to run on all cores.
It changes processes affinities, threads affinities, IRQs affinities
and it sets default_smp_affinity for IRQs.
Also cpu-partitioning profile has been switched from Tuna to this
mechanism.

There is no need for profiles to requires exact NVR of the engine,
or other profiles, relaxed it to NV (i.e. only name, version requirement,
but no release requirement).

The profile is delivered in the new tuned-profiles-cpu-partitioning subpackage.
Also moved defirqaffinity.py to the base package to allow other profiles
to use it.

This plugin can set parameters to kernel modules. It generates
/etc/modprobe.d/tuned.conf file.
Usage:
[modules]
MODULE=OPTION1=VALUE1 OPTION2=VALUE2...
E.g:
[modules]
netrom=nr_ndevs=2
This sets module 'netrom' to have 'nr_ndevs' option set to '2'. The module
can be also forced to load/reload by using special '+r' prefix, e.g.:
[modules]
netrom=+r nr_ndevs=2
Will also cause Tuned to try to remove 'netrom' module (if loaded) and
try to (re)insert it with the specified parameters. The '+r' can be followed
by an optional comma (','), i.e.:
'+r,' for better readability.
By using '+r' the module will be loaded even if not needed.

If there is problem with polkit, it tries to get the UID of the

Dropped dbus at_console policy and implemented polkit authorization.
By the default policy the query actions are allowed for all users, actions
which do modification to the system settings or Tuned state are by default
allowed only for active users that have console, others need admin
authorization.

The bootloader plugin adds there GRUB_CMDLINE_LINUX_DEFAULT tuned setting
which should be removed upon Tuned uninstallation. This commit fixes
the regex used in %postun to correctly remove the Tuned footprint from
there.

It can now tune newly created processes. This functionality
is by default on and can be disabled in tuned profile by setting:
[scheduler]
runtime = 0
This is temporaly workaround. In the future this will be handled
by per-plugin dynamic_tuning configuration and not by "runtime"
option.

It is supported by 'nightly' makefile target. It creates
snapshot from the GIT HEAD, makes mockbuild,
creates repo and uploads result on the fedorapeople.
Also fixed makefile to support parallel builds, added
couple of hopefully useful targets, implemented local
RPM build target 'rpm'.
Other targets (e.g. 'srpm') can be also used to work
with snapshots. It is controlled by BUILD makefile
varible. If set to 'release' normal release is done.
If set to anything else (e.g. 'snapshot') snapshot
is done.
There is also support for GIT snapshots in the upstream
provided SPEC file. Snapshot build is done if
built with '--with snapshot', normal (release) build
is done otherwise.
