Remove EXPERIMENTAL from NFS_FSCACHE
There's currently an open Ubuntu bug[0], with the intent to compile NFS_FSCACHE
(and possibly AFS_FSCACHE, 9P_FSCACHE) into the standard Ubuntu kernel.
However, since *_FSCACHE still depends on EXPERIMENTAL, this won't happen.
As Arjan van de Ven pointed out[1], the EXPERIMENTAL flag doesn't mean that
much any more, I propose the following patch to fs/nfs/Kconfig. I'd do the
same for fs/9p/Kconfig and fs/afs/Kconfig, but as I did not test 9p or AFS, I
feel it would not be appropriate for me to remove the flag.

PM / Hibernate: Fix preallocating of memory
The hibernate memory preallocation code allocates memory to push some
user space data out of physical RAM, so that the hibernation image is
not too large. It allocates more memory than necessary for creating
the image, so it has to release some pages to make room for
allocations made while suspending devices and disabling nonboot CPUs,
or the system will hang due to the lack of free pages to allocate
from. Unfortunately, the function used for freeing these pages,
free_unnecessary_pages(), contains a bug that prevents it from doing
the job on all systems without highmem.
Fix this problem, which is a regression from the 2.6.30 kernel, by
using the right condition for the termination of the loop in
free_unnecessary_pages().

USB: implement non-tree resume ordering constraints for PCI host controllers
This patch (as1331) adds non-tree ordering constraints needed for
proper resume of PCI USB host controllers from hibernation. The main
issue is that non-high-speed devices must not be resumed before the
high-speed root hub, because it is the ehci_bus_resume() routine which
takes care of handing the device connection over to the companion
controller. If the device resume is attempted before the handover
then the device won't be found and it will be treated as though it had
disconnected.
The patch adds a new field to the usb_bus structure; for each
full/low-speed bus this field will contain a pointer to the companion
high-speed bus (if one exists). It is used during normal device
resume; if the hs_companion pointer isn't NULL then we wait for the
root-hub device on the hs_companion bus.
A secondary issue is that an EHCI controlller shouldn't be resumed
before any of its companions. On some machines I have observed
handovers failing if the companion controller is reinitialized after
the handover. Thus, the EHCI resume routine must wait for the
companion controllers to be resumed.
The patch also fixes a small bug in usb_hcd_pci_probe(); an error path
jumps to the wrong label, causing a memory leak.

PM: Start asynchronous resume threads upfront
It has been shown by testing that total device resume time can be
reduced significantly (by as much as 50% or more) if the async
threads executing some devices' resume routines are all started
before the main resume thread starts to handle the "synchronous"
devices.
This is a consequence of the fact that the slowest devices tend to be
located at the end of dpm_list, so their resume routines are started
very late. Consequently, they have to wait for all the preceding
"synchronous" devices before their resume routines can be started
by the main resume thread, even if they are "asynchronous". By
starting their async threads upfront we effectively move those
devices towards the beginning of dpm_list, without breaking their
ordering with respect to their parents and children. As a result,
their resume routines are started much earlier and we are able to
save much more device resume time this way.

PM: Asynchronous suspend and resume of devices
Theoretically, the total time of system sleep transitions (suspend
to RAM, hibernation) can be reduced by running suspend and resume
callbacks of device drivers in parallel with each other. However,
there are dependencies between devices such that we're not allowed
to suspend the parent of a device before suspending the device
itself. Analogously, we're not allowed to resume a device before
resuming its parent.
The most straightforward way to take these dependencies into accout
is to start the async threads used for suspending and resuming
devices at the core level, so that async_schedule() is called for
each suspend and resume callback supposed to be executed
asynchronously.
For this purpose, introduce a new device flag, power.async_suspend,
used to mark the devices whose suspend and resume callbacks are to be
executed asynchronously (ie. in parallel with the main suspend/resume
thread and possibly in parallel with each other) and helper function
device_enable_async_suspend() allowing one to set power.async_suspend
for given device (power.async_suspend is unset by default for all
devices). For each device with the power.async_suspend flag set the
PM core will use async_schedule() to execute its suspend and resume
callbacks.
The async threads started for different devices as a result of
calling async_schedule() are synchronized with each other and with
the main suspend/resume thread with the help of completions, in the
following way:
(1) There is a completion, power.completion, for each device object.
(2) Each device's completion is reset before calling async_schedule()
for the device or, in the case of devices with the
power.async_suspend flags unset, before executing the device's
suspend and resume callbacks.
(3) During suspend, right before running the bus type, device type
and device class suspend callbacks for the device, the PM core
waits for the completions of all the device's children to be
completed.
(4) During resume, right before running the bus type, device type and
device class resume callbacks for the device, the PM core waits
for the completion of the device's parent to be completed.
(5) The PM core completes power.completion for each device right
after the bus type, device type and device class suspend (or
resume) callbacks executed for the device have returned.

the controls array for these 2 different types of exposure (always
disabling one), and;
Add a new autogain algorithm for the coarse exposure case, which normally
changes the gain setting, only touching the exposure setting if the desired
luminance cannot be reached with gain, and after an exposure change once more
first tries gain, etc. Thus avoiding exposure changes, and the resulting

>From Eric Anderson's original email:
1. The tuner on the card doesn't seem to match any standard
ones. I modified an existing tuner entry. Ideally a new tuner
entry should be created. (The only difference from the one I
modified is that the low-to-mid range frequency cut-off is
slightly different, as are the bit config settings.)
2. It wasn't obvious how to choose a second audio input other
than using "radio" as an option. Basically there's two GPIO
audio inputs. Using radio allowed me to avoid major restructuring
to the code. (perhaps other cards don't have this often...)
3. It's not clear that there's a mute setting that works. Not
sure why.
4. I haven't had a chance to test the two Svideo inputs. I set
them to COMPOSITE1 and SVIDEO2, but I'm not sure those are the
correct settings. The standard composite video inputs seem to work.

V4L/DVB: media-spec: Fix documentation mistakes regarding I/O streaming
The media spec contains several errors in the description of the
I/O streaming ioctls, in particular with respect to the userptr
I/O method.
The most important change is that you really need to set count
and index in v4l2_requestbuffer and v4l2_buffer when dealing with
user pointer streaming.

This patch fixes the saa7111a support. This was tested with the mxb driver.

V4L/DVB: saa7146_vv: fix regression where v4l2_device was registered too late
v4l2_device_register needs to be called before the i2c subdevs are loaded.
However, it was called afterwards in the saa7146 driver. This caused an oops
when loading the mxb and hexium drivers. The vv_init function is now split
into two: one registers the v4l2_device, the other does the rest of the
initialization. The three drivers that depend on this have been updated to
call the new vv_devinit function.
Thanks to Michael Hunold for reporting this.
