[PATCH v1 0/3] tools: Add intel-lpmd to the kernel tools

[Maciej Wieczor-Retman]

LPMD (Low Power Mode Daemon) [1] is a program that helps increase
mobile platform power efficiency based on current workload and user
configuration. On newer systems hardware hints guide the decision
making while on older ones software calculated system utilization can be
used.

Depending on the workload LPMD manages active CPUs through cgroups,
and if available balances different sysfs knobs and sliders to get the
most power efficient result. Special emphasis is put on L-cores - low
power CPUs management to get the most value out of newer hardware that
supports such distinction.

Moving the development of LPMD to the kernel tree can increase it's
effectiveness through maintaining higher quality standards and better
community cooperation.

Notable differences between this patchset and the github version [1] are
 - reformatting the whole codebase in kernel coding style
 - the autogen system is dropped in favour of a simpler Makefile

Other than that no functional changes should be introduced in
comparison.
