popcornmix 07d5877ed2 reboot: Use power off rather than busy spinning when halt is requested
reboot: Use power off rather than busy spinning when halt is requested

Busy spinning after halt is dumb
We've previously applied this patch to arch/arm
but it is currenltly missing in arch/arm64

Pi4 after "sudo halt" uses 520mA
Pi4 after "sudo shutdown now" uses 310mA

Make them both use the lower powered option

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.

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.
