Re: [RFC PATCH 17/17] ARM: kernel: save/restore build infrastructure

This patch adds the required Kconfig and Makefile entries to enable and compile common idle code for ARM kernel.

Common idle code depends on CPU_PM platform notifiers to trigger save/restore of kernel subsystems like PMU, VFP, GIC.

 Say N if your target does not have VFP hardware.

SR sounds cryptic. Also since it's PM related _PM_ would be good.

• bool "Save/Restore code support for CPU/Cluster Power Management"
• depends on CPU_V7&& CPU_PM

^ space needed.
