Hi,

first, thanks a lot for advancing PM infrastructure!

> +#define PM_SUSPEND_FREEZE	((__force suspend_state_t) 1)
> +#define PM_SUSPEND_STANDBY	((__force suspend_state_t) 2)
>  #define PM_SUSPEND_MEM		((__force suspend_state_t) 3)
> +#define PM_SUSPEND_MIN		PM_SUSPEND_FREEZE
>  #define PM_SUSPEND_MAX		((__force suspend_state_t) 4)

I'll just pretend to be hopeful that you managed to hunt down all
relevant code sites (possibly even splattered around drivers?)
which may have made illegally hard-coded assumptions
about the number of PM_SUSPEND state "enum"s ;)
(e.g. comparisons - such as "==", "<=" etc. - come into mind)


Review of your patch was all fine, nothing to object about.

Thanks,

Andreas Mohr
