This is basically just a resend of the following patchset:
https://www.spinics.net/lists/linux-clk/msg23141.html
I've just updated the patchset and implemented Shawn's
and Aisheng's comments.
I hope I haven't missed any of their comments.

The SION bit force enables the input buffer, overriding the configuration
driven by the muxed module. It is not located in the pad config register,
but in the mux register and thus needs special handling.

tack handling since I'm getting some build warnings. Those are
due to pushing/popping of a list of regs in which the sp resides. I'll try to
get around those in a next iteration (if necessary), but first I would like to
hear some opinions about this work and if it's worth going forward.

Function ftrace_modify_call provides a way to replace ftrace_stub
with the ftrace function. This helps the klp_ftrace_handler to be
called via ftrace_ops_no_ops, which in turn will set the pc with
the patched function's starting address. This is used for
livepatching.

This adds __ftrace_regs_caller which, unlike __ftrace_caller,
adds register saving/restoring and livepatch handling if
the pc register gets modified by klp_ftrace_handler.

Simple cleanup. No need for two functions here.
The whole work can simply be done inside 'ftrace_module_init'.

Hi,
So I tried to play around a little bit with this patchset. I did a
checkout from:
git://linux-arm.org/linux-power.git energy_model_rfc_v4
and then, when I tried to enable the ENERGY_AWARE from sysfs inside
qemu (x86_64) and I got this:

Sorry, I forgot to mention.
This patch applies to:

If CONFIG_SMP is not defined the build will fail due to
function 'gov_cfs_update_cpu' definition missing.
Added empty static inline definition for NON-SMP systems.

This patch removes function wakeup_gran and its call by calling directly
calc_delta_fair function with sysctl_sched_wakeup_granularity and se as
arguments.

sched/core: Remove unused
Obviously, _rq_ is not used in these two functions, therefore,
there is no reason to be passed as argument.

For a while now, I've started studying the power aware scheduling problem.
And like many other rookies out there I took all the lkml mails related
and read them all (well, almost all) and I saw that there are some
debating on the implementation.I even look over the implementation
proposed of Preeti
