Liang Chen 51d4aae73f sched/fair: optimize scheduler for performance 
1. init util_avg of new task to half the util of big core.
2. treat task wait time as busy time.
3. do not put task to the cpu whose max util can not fit the task.
4. boost cpufreq when a task is wakeup.

if prefer powersave, we can disable this optimization by command:

echo 0 > /proc/sys/kernel/sched_performance_bias

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
