xHCI: Implement AMD PLL quirk
This patch disable the optional PM feature inside the Hudson3 platform under
the following conditions:
1. If an isochronous device is connected to xHCI port and is active;
2. Optional PM feature that powers down the internal Bus PLL when the link is
in low power state is enabled.
The PM feature needs to be disabled to eliminate PLL startup delays when the
link comes out of low power state. The performance of DMA data transfer could
be impacted if system delay were encountered and in addition to the PLL start
up delays. Disabling the PM would leave room for unpredictable system delays
in order to guarantee uninterrupted data transfer to isochronous audio or
video stream devices that require time sensitive information. If data in an
audio/video stream was interrupted then erratic audio or video performance
may be encountered.
AMD PLL quirk is already implemented in OHCI/EHCI driver. After moving the
quirk code to pci-quirks.c and export them, xHCI driver can call it directly
without having the quirk implementation in itself.

USB: Fix unplug of device with active streams
If I unplug a device while the UAS driver is loaded, I get an oops
in usb_free_streams(). This is because usb_unbind_interface() calls
usb_disable_interface() which calls usb_disable_endpoint() which sets
ep_out and ep_in to NULL. Then the UAS driver calls usb_pipe_endpoint()
which returns a NULL pointer and passes an array of NULL pointers to
usb_free_streams().
I think the correct fix for this is to check for the NULL pointer
in usb_free_streams() rather than making the driver check for this
situation. My original patch for this checked for dev->state ==
USB_STATE_NOTATTACHED, but the call to usb_disable_interface() is
conditional, so not all drivers would want this check.
Note from Sarah Sharp: This patch does avoid a potential dereference,
but the real fix (which will be implemented later) is to set the
.soft_unbind flag in the usb_driver structure for the UAS driver, and
all drivers that allocate streams. The driver should free any streams
when it is unbound from the interface. This avoids leaking stream rings
in the xHCI driver when usb_disable_interface() is called.

USB: EHCI: unlink unused QHs when the controller is stopped
This patch (as1458) fixes a problem affecting ultra-reliable systems:
When hardware failover of an EHCI controller occurs, the data
structures do not get released correctly. This is because the routine
responsible for removing unused QHs from the async schedule assumes
the controller is running properly (the frame counter is used in
determining how long the QH has been idle) -- but when a failover
causes the controller to be electronically disconnected from the PCI
bus, obviously it stops running.
The solution is simple: Allow scan_async() to remove a QH from the
async schedule if it has been idle for long enough _or_ if the
controller is stopped.

avr32: init cannot ignore signals sent by force_sig_info()
We can delete the code that checks to see if we're sending an ignored
signal to init because force_sig_info() already handles this case.
force_sig_info() will kill init even if the signal handler is SIG_DFL
and the scenario described in the comment where init might "generate
the same exception over and over again" cannot occur (force_sig_info()
clears SIGNAL_UNKILLABLE to ensure that init will die).
Also, the use of is_global_init() is not correct in the multhreaded
case, as Oleg Nesterov explains,
"is_global_init() is not right in theory, /sbin/init can be
multithreaded. And, this doesn't cover the sub-namespace
inits... I'd suggest to check SIGNAL_UNKILLABLE, but looking
closer I think you can simply remove this code."
It seems this code was copied from arch/powerpc in March 2007 in commit
623b0355d5b1 "[AVR32] Clean up exception handling code"
but the code was deleted from arch/powerpc in November 2009 in commit

USB: musb: blackfin: work around anomaly
05000450
DMA mode 1 data corruption anomaly on Blackfin systems. This issue is
specific to the Blackfin silicon as the bug appears to be related to the
connection of the musb ip to the bus/dma fabric.
Data corruption when using USB DMA mode 1. (Issue manager 17-01-0105)
DMA mode 1 allows large size transfers to generate a single interrupt
at the end of the entire transfer. The transfer is split up in packets
of length specified in the Maximum Packet Size field for that endpoint.
If the transfer size is not an integer multiple of the Maximum Packet
Size, a short packet will be present at the end of the transfer.
Under certain conditions this packet may be corrupted in the USB FIFO.
Workaround:
Use DMA mode 1 to transfer (n* Maximum Packet Size) and schedule DMA
mode 0 to transfer the short packet.
As an example if your transfer size is 33168 bytes and Maximum Packet
Size equals 512, schedule [33168 - (33168 mod 512)] in DMA mode 1 and
the remainder (33168 mod 512) in DMA mode 0.

usb: musb: temporarily make it bool
Due to the recent changes to musb's glue layers,
we can't compile musb-hdrc as a module - compilation
will break due to undefined symbol musb_debug. In
order to fix that, we need a big re-work of the
debug support on the MUSB driver.
Because that would mean a lot of new code coming
into the -rc series, it's best to defer that to
next merge window and for now just disable module
support for MUSB.
Once we get the refactor of the debugging support
done, we can simply revert this patch and things
will go back to normal again.

Input: add KEY_IMAGES specifically for AL Image Browser
Many media center remotes have buttons intended for jumping straight to
one type of media browser or another -- commonly, images/photos/pictures,
audio/music, television, and movies. At present, remotes with an images
or photos or pictures button use any number of different keycodes which
sort of maybe fit. I've seen at least KEY_MEDIA, KEY_CAMERA,
KEY_GRAPHICSEDITOR and KEY_PRESENTATION. None of those seem quite right.
In my mind, KEY_MEDIA should be something more like a media center
application launcher (and I'd like to standardize on that for things
like the windows media center button on the mce remotes). KEY_CAMERA is
used in a lot of webcams, and typically means "take a picture now".
KEY_GRAPHICSEDITOR implies an editor, not a browser. KEY_PRESENTATION
might be the closest fit here, if you think "photo slide show", but it
may well be more intended for "run application in full-screen
presentation mode" or to launch something like magicpoint, I dunno.
And thus, I'd like to have a KEY_IMAGES, which matches the HID Usage AL
Image Browser, the meaning of which I think is crystal-clear. I believe
AL Audio Browser is already covered by KEY_AUDIO, and AL Movie Browser
by KEY_VIDEO, so I'm also adding appropriate comments next to those
keys.

The extent_io code can take cached pointers into the extent state trees,

A help function was added to uncache the state, and it was testing
the same set of conditionals. This can leak in very strange corner

The uncaching should be unconditional. Once we have a ref on the

vm: fix mlock() on stack guard page
Commit
53a7706d5ed8 ("mlock: do not hold mmap_sem for extended periods
of time") changed mlock() to care about the exact number of pages that
__get_user_pages() had brought it. Before, it would only care about
errors.
And that doesn't work, because we also handled one page specially in
__mlock_vma_pages_range(), namely the stack guard page. So when that
case was handled, the number of pages that the function returned was off
by one. In particular, it could be zero, and then the caller would end
up not making any progress at all.
Rather than try to fix up that off-by-one error for the mlock case
specially, this just moves the logic to handle the stack guard page
into__get_user_pages() itself, thus making all the counts come out
right automatically.

It turns out that libmount misparses it because it adds a '-' character

separator string (" - ") at the end of all the optional arguments.
Upstream libmount (in the util-linux tree) has been fixed, but until
that fix actually percolates up to users, we'd better not expose this
change in the kernel.
Let's revisit this later (possibly by exposing the UUID without any '-'
characters in it, avoiding the user-space bug).
