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.

On a resume, when the power is lost during hibernate, the USB core will
call hub_reset_resume for the xHCI USB 2.0 roothub, but not for the USB
3.0 roothub:
[ 164.748310] usb usb1: root hub lost power or was reset
[ 164.748353] usb usb2: root hub lost power or was reset

...
[ 164.870054] hub 3-0:1.0: hub_reset_resume
This causes issues later, because the USB core assumes the USB 3.0 hub
attached to the USB 3.0 roothub is still active. It attempts to queue a
control URB for the external hub, which fails because all the device
slot contexts were released when the USB 3.0 roothub lost power:

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.
This should be queued for stable trees back to 2.6.35.

Currently, when resetting a device, xHCI driver disables all but one
endpoints and frees their rings, but leaves alone any streams that
might have been allocated. Later, when users try to free allocated
streams, we oops in xhci_setup_no_streams_ep_input_ctx() because
ep->ring is NULL.
Let's free not only rings but also stream data as well, so that
calling free_streams() on a device that was reset will be safe.
This should be queued for stable trees back to 2.6.35.

When suspending/resuming, the common task freezing code will run in
parallel and freeze processes on each core. This is because the code
uses the non-smp version of memory barriers (as well it should).
The Blackfin smp barrier logic at the moment contains the cache sync
logic, but the non-smp barriers do not. This is incorrect as Rafel
summarized:

When we get a port status change event, we need to figure out what type of
port it came from: a USB 3.0 port, or a USB 2.0/1.1 port. We can't know
which usb_hcd to use until that point, so hcd will be NULL for part of the
function. Unfortunately, if any of the sanity checks fail, we'll jump to
the cleanup label before hcd is set to a valid pointer, and then we'll
attempt to tell the USB core to kick the hcd, which is NULL.
Skip kicking the roothub if the sanity checks fail.

When parsing exponent-expressed intervals we subtract 1 from the
value and then expect it to match with original + 1, which is
highly unlikely, and we end with frequent spew:
usb 3-4: ep 0x83 - rounding interval to 512 microframes
Also, parsing interval for fullspeed isochronous endpoints was
incorrect - according to USB spec they use exponent-based
intervals (but xHCI spec claims frame-based intervals). I trust
USB spec more, especially since USB core agrees with it.
This should be queued for stable kernels back to 2.6.31.

The logic of the handling Missed Service Error Events was pretty
confusing as we were checking the same condition several times.
In addition, it caused compiler warning since the compiler could
not figure out that event_trb is actually unused in case we are
skipping current TD.
Fix that by rearranging "skip" condition checks, and factor out
skip_isoc_td() so that it is called explicitly.

The driver did not take the zero flag in the USB request. If the
request length is the same as the endpoint's maxpacket, an additional
ZLP with no data has to be transmitted.
The method used here is inspired to what is done in fsl_udc_core.c
(and pxa27x_udc.c and at91_udc.c) where this is supported.
There already was a discussion about this topic with people from
Keymile, and I propose here a better implementation:

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.

While decoding a secinfo reply, I store the list of supported sec
flavors on a page accessible through res->flavors. Before reading
each new flavor, I do some math to determine if there is enough
space left on this page, and I break out of my read look if there
isn't. In order to perform this check correctly, I need to use the
address of res->flavors, rather than the address of res.
When this loop was broken early I lied to the caller and told them
that the entire list had been decoded. This could lead to problems
if the caller tries to use any the garbage data claiming to be a
valid sec flavor. I fixed this by using res->flavors->num_flavors
as a counter, incrementing it every time a sec flavor is
successfully decoded.

This reverts commit c191a836a908d1dd6b40c503741f91b914de3348.
It causes known regressions for programs that expect to be able to use
SO_REUSEADDR to shutdown a socket, then successfully rebind another
socket to the same ID.
Programs such as haproxy and amavisd expect this to work.
This should fix kernel bugzilla 32832.

Machines are getting deadlock in four node cluster environment.
All nodes are accessing (find /gfs2 -depth -print|cpio -ocv > /dev/null)
200 GB storage on a GFS2 filesystem.
This result in memory fragmentation and driver receives 18 frags for
1448 byte packets.
For non tso packet, fw drops the tx request, if it has >14 frags.
Fixing it by pulling extra frags.

Commit ce6120cc(ASoC: Decouple DAPM from CODECs) changed the signature of
snd_soc_dapm_widgets_new to take an pointer to a snd_soc_dapm_context instead of
a snd_soc_codec. The call to snd_soc_dapm_widgets_new in jz4740_codec_dev_probe
was not updated to reflect this change, which results in a compiletime warning
and a runtime OOPS.
Since the core code calls snd_soc_dapm_widgets_new after the codec has been
registered it can be dropped here.
