ARM: compressed/head.S: work around new binutils warning

In August 2012, Matthew Gretton-Dann checked a change
into binutils labelled "Error on obsolete & warn on
deprecated registers", apparently as part of ARMv8
support. Apparently, this was supposed to emit
the message "Warning: This coprocessor register access
is deprecated in ARMv8" when using certain mcr/mrc
instructions and building for ARMv8. Unfortunately,
the message that is actually emitted appears to be
'(null)', which is less helpful in comparison.

Even more unfortunately, this is biting us on
every single kernel build with a new gas, because
arch/arm/boot/compressed/head.S and some other files
in that directory are built with -march=all since
kernel commit 80cec14a8 "[ARM] Add -march=all to
assembly file build in arch/arm/boot/compressed"
back in v2.6.28.

This patch reverts Russell's nice solution and
replaces it with a more complex one that sprinkles
.arch statements inside of the head.S file in
functions that are executed in different architecture
levels, which seems to solve the original problem
just as well, and gets rid of the new one, too.

Without this patch, building anything results in:

intellidemand: Add support to consider other cpu load when scaling frequencies

Currently only current cpu load is considered when frequency scaling.
As a side effect of this when scheduler migrates a thread to a slower
core, the execution time increases unexpectedly.

The new algorithm not only considers current cpu load for frequency
scaling, but also takes into account load of other online cpus. The
treshold for this can be controlled using up_threshold_any_cpu_load.
When the up_threshold_any_cpu_load is crossed in any cpu then the
current cpu is set to sync_freq.

Also, when more than one cpu is online a two step ramp-up mechanism
is used. When the up_threshold_multi_core is crossed the cpu is ramped
up to optimal_freq which is less than policy->max and set to a power
friendly value.

cpufreq: Avoid using smp_processor_id() in preemptible context

The intent of the code is to determine which CPU this work item

in a wrapper struct around the work struct. Do this so we avoid
this problem.

cpufreq/cpufreq_intellidemand: intellidemand cpufreq
 governor (version 4.0)

Intellidemand is inspired by ondemand governor. Its main features are:

 - auto cpu hotplugging based on runnable thread average calculations
 - detection of browsing mode (long screen on activities with moderate run
   queue depth =< 45 )
 - limit max frequencies when in browsing mode to conserve battery for long
   duration tasks

Browsing State Determination:
 1- Browsing state is enabled as power-on default. Browsing state is disabled
    when run queue depth is > 45 (very high instantaneous spikes)

Browsing State Limit Max Freq Logic (sliding window algorithm):
 1- While Screen is ON > 3 min, and average load of the CPU is < 35%, then
    CPU Max frequencies will remain power-on default
 2- While Screen is On, if average CPU load > 35%, both CPUs max frequencies
    will be limited to a lower user configurable max value
 3- While Screen is On, After both CPUs' Max is limited to lowered max, when
    the average CPU load has dropped down to less than < 25%, then both CPUs
    Max freq will be restored to back to power-on default

Runnable Thread Auto-hotplug (fast hotplug / slow unplug algorithm):
 1- When average number of running thread is < threshold, 2nd cpu will be
    unplugged.
 2- When > threshold, 2nd cpu will be hotplugged.
 3- The logic applies a fast hotplug and slow unplug algorithm so 2nd core
    will stay enabled longer to help deal with performance spikes

changes from Ver 2.0 -> Ver 3.0:
  - remove GPU Busy dependency for browsing state detection (this will make
    the governor more portable to other platforms without specific GPU
    architecture knowledge)

dependencies:
  -- Qualcomm's run queue average logic (SOC independent logic)
  -- TI's runnable thread average logic (SOC independent logic)
