Subject: [PATCH 0/3] PM / sleep: Make it possible to change the labeling of sleep states

Hi,

In accordance with the changelog of patch [3/3], there are systems where the
only available sleep state is PM_SUSPEND_FREEZE, so neither "mem" nor "standby"
are present in /sys/power/state.  As a result, some user space frameworks are
unable to use suspend on those systems even though the "freeze" sleep state
is there to use.

To address this issue, patch [3/3] adds a command line argument to switch the
behavior so that sleep states are enumerated from the deepest to the shallowest
available and the deepest one is always "mem".  The default is the current
behavior, of course.

Patches [1-2/3] do some preparatory modifications that I think are better done
separately.

Thanks!
