Hi kernel guys!
This patchset aims to clean all unused and commented macros.
For this challenge, forgotten-macros tool helped us.
Perhaps there may be false positives in your code.

This patchset creates an arch_scale_freq_power function for ARM, which is used
to set the relative capacity of each core of a big.LITTLE system. It also
removes
the broken power estimation of x86.
Modification since v3:
- Add comments
- Add optimization for SMP system
- Ensure that capacity

This factorization has also been proposed in another patch that has not been
merged yet:

Use cpu compatibility field and clock-frequency field of DT to

the cpu_power field accordingly.
This patch enables to put more running tasks on big cores than

For archaeological interest, fixing this code would require dealing with

Hi Bjorn and Yinghai,
What's the policy to export a symbol by EXPORT_SYMBOL()
or EXPORT_SYMBOL_GPL()? I know the legal difference, but don't
know when I should mark a symbol as GPL.
Thanks!
