This will disable suspend (like if you're showing a demo off).

Sorry, this will work better.

Some pinctrl drivers (Tegra at least) program a pin to be a GPIO in a
completely different manner than they select which function to mux out of
that pin. In order to support a single "free" pinmux_op, the driver would
need to maintain a per-pin state of requested-for-gpio vs. requested-for-
functio

With a lot of small tasks, the softirq sched is nearly never called
when no_hz is enable. The load_balance is mainly called with
the newly_idle mode which doesn't update the cpu_power.
Add a next_update field which ensures a maximum update period when
there is short activity

arch_update_cpu_topology function is called by the scheduler
before building its sched_domain hierarchy. Move the update
of the cpu topology masks in this function instead of defining
it in the the store_cpu_topology which is executed only once per cpu.

The sched_mc feature has been originally designed to improve power
consumption of multi-package system and several architecture functions
are available to tune the topology and the scheduler's parameters when
scheduler rebuilds the sched_domain hierarchy (change the
sched_mc_power_savings level). T

Hi Nicolas,
As suggested by you, I have cherry picked the necessary patches from
rmk-next tree and applied it on top of latest linaro tree.
Please pull them for next linaro release. The pull path is,
