[PATCH 00/11] cpufreq: Keep policy->freq_table sorted

[Viresh Kumar]

Hi Rafael,

This series fixes all cpufreq drivers that provide a 'target_index'
callback or in other words, which provide a freq-table to cpufreq core,
to make sure they *only* use the 'index' argument to ->target_index()
with the policy->freq_table.

This change allows us to remove the (duplicate) sorted-freq-table, which
was added by following series:

[PATCH V2 0/2] cpufreq: Use sorted frequency tables

The final code looks like this:
- drivers provide a freq table to the cpufreq core
- core makes a copy of that and sort that in ascending order of
  frequencies. This is what we get from policy->freq_table.
- drivers can now free the freq-table they provided earlier.
- ->target_index() contains the 'index' to this sorted
  policy->freq_table.

This is based of the two series I have posted until now:

[PATCH V2 0/6] cpufreq: cleanups and reorganization
[PATCH V2 0/2] cpufreq: Use sorted frequency tables

All the patches are pushed here for testing in case anyone wants to try:

git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git cpufreq/sorted-freq-table

The 3 series combined makes freq-table traversing to find a match really
fast and efficient. Which will also allow us to use it for new governors
like schedutil.
