sound control 3.x: Initial GPL release for WCD9310 Audio Codec

This is first official GPL release based on my private implementation.

This release has been tested for Mako and Flo officially.  It may work
with other devices using the same WCD9310 Audio Codec as well, but not tested

drivers: thermal: properly limit CPU frequency when the temperature is too hot: if we throttle too much games will lag so we'll only scale down to 1026MHz until the device cools down, then back to 1512MHz again. Added other smaller routine changes to make it work properly.

thermal: tsens8960: Increase the polling rate

Change the polling rate at which the sensors temperature
is read from 1 second to .25 seconds. On faster parts
there is a need to poll the temperature at a higher
frequency to improve reporting temperature changes.

net: flow: Prevent bringing up new CPUs during per-CPU initialization

In a rare race-condition, it's possible that a CPU will be brought
online between when the for_each_online_cpu() loop executes to
call flow_cache_cpu_prepare(), and when the hotplug notifier for
calling this same function is registered. If this happens,
flow_cache_cpu_prepare() will never be called for the new CPU,
resulting in crashes due to uninitialized per-cpu data.

Fix this by preventing CPUs from being added or removed during
this small but sensitive window.

cpufreq: Manage only online cpus

cpufreq core doesn't manage offline cpus and if driver->init() has returned
mask including offline cpus, it may result in unwanted behavior by cpufreq core
or governors.

We need to get only online cpus in this mask. There are two places to fix this
mask, cpufreq core and cpufreq driver. It makes sense to do this at common place
and hence is done in core.

binfmt_elf.c: use get_random_int() to fix entropy depleting

Changes:
--------
v4->v3:
- s/random_stack_user()/get_atrandom_bytes()/
- Move this function to ahead of its use to avoid the predeclaration.

v3->v2:
- Tweak code comments of random_stack_user().
- Remove redundant bits mask and shift upon the random variable.

v2->v1:
- Fix random copy to check up buffer length that are not 4-byte multiples.

v3 can be found at:
http://www.spinics.net/lists/linux-fsdevel/msg59597.html
v2 can be found at:
http://www.spinics.net/lists/linux-fsdevel/msg59418.html
v1 can be found at:
http://www.spinics.net/lists/linux-fsdevel/msg59128.html

Thanks,

Entropy is quickly depleted under normal operations like ls(1), cat(1),
etc...  between 2.6.30 to current mainline, for instance:

$ cat /proc/sys/kernel/random/entropy_avail
3428
$ cat /proc/sys/kernel/random/entropy_avail
2911
$cat /proc/sys/kernel/random/entropy_avail
2620

We observed this problem has been occurring since 2.6.30 with
fs/binfmt_elf.c: create_elf_tables()->get_random_bytes(), introduced by
f06295b44c296c8f ("ELF: implement AT_RANDOM for glibc PRNG seeding").

/*
 * Generate 16 random bytes for userspace PRNG seeding.
 */
get_random_bytes(k_rand_bytes, sizeof(k_rand_bytes));

The patch introduces a wrapper around get_random_int() which has lower
overhead than calling get_random_bytes() directly.

With this patch applied:
$ cat /proc/sys/kernel/random/entropy_avail
2731
$ cat /proc/sys/kernel/random/entropy_avail
2802
$ cat /proc/sys/kernel/random/entropy_avail
2878
