Add support to instantiate LM90-compatible sensors from a device-tree
configuration.
When the kernel has device tree support, we avoid doing the auto-detection
as probing the busses might mess-up sensitive I2C devices or trigger long
timeouts on non-functional busses.

On tickless system, one CPU runs load balance for all idle CPUs.
The cpu_load of this CPU is updated before starting the load balance
of each other idle CPUs. We should instead update the cpu_load of the

Peter,
your patch also solves the 'phantom' big cores that can appear on HMP
system because big cores have a cpu_power >= SCHED_POWER_SCALE in
order to express a higher capacity than LITTLE cores.

Yes, I found I can use 'ip route replace' command to change the 'src'
address as workaround. Julian also responded in another thread that He
could come up with a patch to sort ip with scope, primary, secondary
preferences.

sorry Julian to miss your point after reading the __inet_del_ifa and
see the rtmsg_ifa, fib_del_ifaddr/fib_add_ifaddr, I can try another
patch and actually test if the patches changes works as it is
intended, not just checking from ip binary output.

I think it is good idea to add these preferences flags and sorted
them, but my code knowledge is limited to implement it as I am still
learning, I can help testing :)
