GPIO reworked
Here is patch for GPIO's handling.
It allows to support I2C on GPIO's and per board LNB control through GPIO's.
Also incuded some support for Hendrik Skarpeid card.
For those, who needs to tweak the driver,
I think it is clear how to change and test GPIO's for LNB and other GPIO related stuff now.
[mchehab@redhat.com: I2C_CLASS_TV_DIGITAL is deprecated. removed to avoid breaking compilation]

renesas_usbhs driver can use external interrupt mode
(which come from USB-PHY) or autonomy mode (it use own interrupt)
for detecting connection/disconnection when Function.
And it will be power OFF while it has been disconnecting
if external interrupt mode is selected.
mackerel board has 2 USB ports.
But we can not use external interrupt mode
on CN22 USB0 port which is only for USB Function.
IRQ7-PORT40 is already used by Touchscreen,
and USB-PHY needs IRQ7-PORT167.
It is impossible to use IRQ7 demux on mackerel.
We can use external interrupt mode USB-Function on "USB1".
USB1 can become Host by r8a66597, and become Function by renesas_usbhs.
But don't select both drivers in same time.
These 2 drivers are not supporting IRQ SHARD.

In order to allow quirks functions to hook up to the standard feature
unit op tables, this patch exports a pointer to the struct that is used
internally.
That way, all the code handling the control can be kept private, and
external code can reference the symbol to re-use it.

This patch renames add_control_to_empty() to snd_usb_mixer_add_control()
and exports it, so the quirks functions can make use of it.
Also, as "struct mixer_build" is private to mixer.c, rewrite the
function to take an argument of type "struct usb_mixer_interface"
instead.

We're going to support partial extent moving, which may split entire extent
movement into pieces to compromise the insuffice allocations, it eases the
'ENSPC' pain and makes the whole moving much less likely to fail, the downside
is it may make the fs even more fragmented before moving, just let the userspace
make a trade-off here.

the basic logic of moving extents for a file is pretty like punching-hole
sequence, walk the extents within the range as user specified, calculating
an appropriate len to defrag/move, then let ocfs2_defrag/move_extent() to
do the actual moving.
This func ends up setting 'OCFS2_MOVE_EXT_FL_COMPLETE' to userpace if operation
gets done successfully.

It's a relatively complete function to accomplish defragmentation for entire

The moving range of __ocfs2_move_extent() was within one extent always, it
consists following parts:
1. Duplicates the clusters in pages to new_blkoffset, where extent to be moved.
2. Split the original extent with new extent, coalecse the nearby extents if possible.
3. Append old clusters to truncate log, or decrease_refcount if the extent was refcounted.

This change unifies the initial handling of a pin's state with the code to
update a pin's state after a hotplug (unsolicited response) event. The
initial probing, and all updates, are now routed through hdmi_present_sense.
The stored PD and ELDV status is now always derived from GetPinSense verb
execution, and not from the data in the unsolicited response. This means:
a) The WAR for NVIDIA codec's UR.PD values ("old_pin_detect") can be
removed, since this only affected the no-longer-used unsolicited
response payload.
b) In turn, this means that most NVIDIA codecs can simply use
patch_generic_hdmi instead of having a custom variant just to set
old_pin_detect.
c) When PD && ELDV becomes true, no extra verbs are executed, because the
GetPinSense that was previously executed by snd_hdmi_get_eld (really,
hdmi_eld_valid) has simply moved into hdmi_present_sense.
d) When PD && ELDV becomes false, there is a single extra GetPinSense verb
executed for codecs where old_pin_detect wasn't set, i.e. some NVIDIA,
and all ATI/AMD and Intel codecs. I doubt this will be a performance
issue.
The new unified code in hdmi_present_sense also ensures that eld->eld_valid
is not set unless eld->monitor_present is also set. This protects against
potential invalid combinations of PD and ELDV received from HW, and
transitively from a graphics driver.
Also, print the derived PD/ELDV bits from hdmi_present_sense so the kernel
log always displays the actual state stored, which will differ from the
values in the unsolicited response for NVIDIA HW where old_pin_detect was
previously set.
Finally, a couple of small tweaks originally by Takashi:
* Clear the ELD content to zero before reading it, so that if it's not
read (i.e. when !(PD && ELDV)) it's in a known state.
* Don't show ELD fields in /proc ELD files when the ELD isn't valid.
The only possibility I can see for regression here is a codec where the
GetPinSense verb returns incorrect data. However, we're already exposed
to that, since that data is used (a) from hdmi_add_pin to set up the
initial pin state, and (b) within snd_hda_input_jack_report to query
a pin's presence value. As such, I don't believe any HW has bugs here.

This new code is a bit more complicated than former ones, the goal is to
show user all statistics required to take a deep insight into filesystem
on how the disk is being fragmentaed.
The goal is achieved by scaning global bitmap from (cluster)group to group
to figure out following factors in the filesystem:
- How many free chunks in a fixed size as user requested.
- How many real free chunks in all size.
- Min/Max/Avg size(in) clusters of free chunks.
- How do free chunks distribute(in size) in terms of a histogram,
just like following:
---------------------------------------------------------
Extent Size Range : Free extents Free Clusters Percent
32K... 64K- : 1 1 0.00%
1M... 2M- : 9 288 0.03%
8M... 16M- : 2 831 0.09%
32M... 64M- : 1 2047 0.23%
128M... 256M- : 1 8191 0.92%
256M... 512M- : 2 21706 2.43%
512M... 1024M- : 27 858623 96.29%
---------------------------------------------------------

The new code is dedicated to calculate free inodes number of all inode_allocs,
then return the info to userpace in terms of an array.
Specially, flag 'OCFS2_INFO_FL_NON_COHERENT', manipulated by '--cluster-coherent'
from userspace, is now going to be involved. setting the flag on means no cluster
coherency considered, usually, userspace tools choose none-coherency strategy by
default for the sake of performace.
