RE: [PATCH v5 23/34] arm_mpam: Allow configuration to be applied and restored during cpu online

[Shaopeng Tan (Fujitsu)]

> From: James Morse <james.morse@xxxxxxx>
> 
> When CPUs come online the MSC's original configuration should be restored.
> 
> Add struct mpam_config to hold the configuration. For each component, this
> has a bitmap of features that have been changed from the reset values. The
> mpam_config is also used on RIS reset where all bits are set to ensure all
> features are reset.
> 
> Once the maximum partid is known, allocate a configuration array for each
> component, and reprogram each RIS configuration from this.
