This reverts commit 5c1de006e8e66b0be05be422416629e344c71652.
While the original commit makes it easier to run cpupower from the
local build directory, it also leaves the binary with a rather poor
rpath of './' in it after it is installed on a system via 'make install'.
This is considered bad practice and can cause cpupower to fail in
rpmbuild with the following error:
ERROR 0004: file '/usr/bin/cpupower' contains an insecure rpath './' in [./]
error: Bad exit status from /var/tmp/rpm-tmp.A6u26r (%install)
Bad exit status from /var/tmp/rpm-tmp.A6u26r (%install)
Developers should be able to use LD_LIBRARY_PATH to achieve the same
effect and not introduce rpath into the binary.

The cpupower tool, when compiled against libcpupower.so fail's to run as
the linker file path's are missing during compilation. So added changes
in the Makefile to run cpupower tool, which helps us run the tool
without doing a 'make install'.

There has been confusion all the time about which mailing list to follow
for cpufreq activities, linux-pm@vger.kernel.org or cpufreq@vger.kernel.org.
Since patches sent to cpufreq@vger.kernel.org don't go to Patchwork
which is a maintenance workflow problem, make linux-pm@vger.kernel.org
the official mailing list for cpufreq stuff and remove all references
of cpufreq@vger.kernel.org from kernel source.
Later, we can request that the list be dropped entirely.

Example:

will disable C-state 3 on all processors (set commands are active on
all CPUs by default), same as:
cpupower -c all idle-set -d 3

The clean targets from the cpupower tools' Makefiles use brace expansion to
remove some generated files. However, the default shells on many systems do
not support this feature resulting in some generated files not being removed
by clean.

The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.
This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.
Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

This patch allows cpupower tool to generate its output files in a
seperate directory. This is now possible by passing the 'O=<path>' to
the command line.
This can be usefull for a normal user if the kernel source code is
located in a read only location.
This is patch stole some bits of the perf makefile.

Which makes the implementation independent from cpufreq drivers.
Therefore this would also work on a Xen kernel where the hypervisor
is doing frequency switching and idle entering.

As cpupowerutils is intended to be included into the kernel sources,
use the kernel versioning instead of a custom version.
The script utils/version-gen.sh is largely based on the script already
found in tools/perf/util/PERF-VERSION-GEN .

CPU power consumption vs performance tuning is no longer
limited to CPU frequency switching anymore: deep sleep states,
traditional dynamic frequency scaling and hidden turbo/boost
frequencies are tied close together and depend on each other.
The first two exist on different architectures like PPC, Itanium and
ARM, the latter (so far) only on X86. On X86 the APU (CPU+GPU) will
only run most efficiently if CPU and GPU has proper power management
in place.
Users and Developers want to have *one* tool to get an overview what
their system supports and to monitor and debug CPU power management
in detail. The tool should compile and work on as many architectures
as possible.
Once this tool stabilizes a bit, it is intended to replace the
Intel-specific tools in tools/power/x86
