max8997_vibrator: remove hardcoded pwm_duty

the px boards have larger duty values, so with the hardcoded u1
values vibration is weak

patch set 2: replace pwm_duty_* macros with global variables

cpufreq: Move voltage control to 4210 file

This is CPU-specific, doesn't belong in general 4210 stuff

cpufreq: Reset MAX8997 predefineds when needed

The MAX8997 stores up to 8 predefined voltage levels that can
be set rapidly using GPIOs.  If there are no predefineds,
"BUCK1 no predefined" errors are given.  This will happen
if the voltage table has been altered.  This resets the redefines
each time the table is altered.

wakelock: use single threaded workqueueus

Avoid the concurrency management that could delay execution if there's
lots of workqueue traffic (and allow the runqueue to run on any CPU).

Lots of workqueue traffic can be generated by setting
ondemand/sampling_rate to 10000.

mali: Clean up arch

The arch directory is supposed to be a symlink to the proper
architecture directory.  Add orion-m400 and symlink to it.

(orion-m400 and pegasus-m400 seem to have the same config.h
but keep em' separate anyway.)

mali: Fix bad file formatting.

Somehow this file wound up becoming Mac-formatted...

mali: Update platform code.

Pull it from pegasus, remove the obvious Pegasus-specific crap,
and also enable Mali 3-step.

Not yet user-controllable.  That's for a later patch when
our GPU isn't gulping down juice.

stand-hotplug:  Add enhanced tunables

Now has separate hotplugging rates for screen off/on.

Defaults to disallowing any additional cores when screen is
off.

Also allows hotplugging to be disabled until CPU frequency goes
over a certain thresholed - default 800 MHz.

WARNING:  Do not apply this to any kernel that will build for
devices with more than 2 cores.  Since the smdk4210 tree
only builds for dual-core devices this is fine, but
don't apply it to smdk4412 unless you want pain.

mali: Fix for getting the subversion revision

Prevents compiler errors due to unescaped strings, ie:

    arm-eabi-gcc: error: directory: No such file or directory
    arm-eabi-gcc: error: directory": No such file or directory

Forward port from 3d59d993.

ARM: SMP: use a timing out completion for cpu hotplug

    ARM: SMP: use a timing out completion for cpu hotplug

    Rather than open-coding the jiffy-based wait, and polling for the
    secondary CPU to come online, use a completion instead.  This
    removes the need to poll, instead we will be notified when the
    secondary CPU has initialized.

d710 config: Regenerate configs for new changes

add ondemand flexrate, might be useful with a power HAL.
add sio io scheduler, and set as default
enable KSM support
   enabled/disabled in Settings -> Performance -> Memory management
enable 1400mhz max clock speed
Add CONFIG_CMDLINE_APPEND_SERIAL to append serial to kernel cmdline

this fixes the issue of the bootloader no longer passing the serial to
the kernel and serial showing as unknown on some samsung devices
add module license to prevent kernel taint
