commit 75e1a2ae1f61ce1ae640410ba757bba84bd9fefe upstream.
Debug port in-use determination must be done before the controller gets
reset the first time, i.e. before the call to ehci_setup() as of commit
1a49e2ac9651df7349867a5cf44e2c83de1046af. That commit effectively
rendered commit 9fa5780beea1274d498a224822397100022da7d4 useless.
While moving that code around, also fix the BAR determination - the
respective capability field is a 3- rather than a 2-bit one -, and use
PCI_CAP_ID_DBG instead of the literal 0x0a.
It's unclear to me whether the debug port functionality is important
enough to warrant fixing this in stable kernels too.

commit 55c1945edaac94c5338a3647bc2e85ff75d9cf36 upstream.
A high speed control or bulk endpoint may have bInterval set to zero,
which means it does not NAK. If bInterval is non-zero, it means the
endpoint NAKs at a rate of 2^(bInterval - 1).
The xHCI code to compute the NAK interval does not handle the special
case of zero properly. The current code unconditionally subtracts one
from bInterval and uses it as an exponent. This causes a very large
bInterval to be used, and warning messages like these will be printed:
usb 1-1: ep 0x1 - rounding interval to 32768 microframes, ep desc says 0 microframes
This may cause the xHCI host hardware to reject the Configure Endpoint
command, which means the HS device will be unusable under xHCI ports.
This patch should be backported to kernels as old as 2.6.31, that contain
commit dfa49c4ad120a784ef1ff0717168aa79f55a483a "USB: xhci - fix math in

commit c52804a472649b2e5005342308739434cbd51119 upstream.
The USB core hub thread (khubd) is designed with external USB hubs in
mind. It expects that if a port status change bit is set, the hub will
continue to send a notification through the hub status data transfer.
Basically, it expects hub notifications to be level-triggered.
The xHCI host controller is designed to be edge-triggered on the logical
'OR' of all the port status change bits. When all port status change
bits are clear, and a new change bit is set, the xHC will generate a
Port Status Change Event. If another change bit is set in the same port
status register before the first bit is cleared, it will not send
another event.
This means that the hub code may lose port status changes because of
race conditions between clearing change bits. The user sees this as a
"dead port" that doesn't react to device connects.
The fix is to turn on port polling whenever a new change bit is set.
Once the USB core issues a hub status request that shows that no change
bits are set in any USB ports, turn off port polling.
We can't allow the USB core to poll the roothub for port events during
host suspend because if the PCI host is in D3cold, the port registers
will be all f's. Instead, stop the port polling timer, and
unconditionally restart it when the host resumes. If there are no port
change bits set after the resume, the first call to hub_status_data will
disable polling.
This patch should be backported to stable kernels with the first xHCI
support, 2.6.31 and newer, that include the commit
0f2a79300a1471cf92ab43af165ea13555c8b0a5 "USB: xhci: Root hub support."
There will be merge conflicts because the check for HC_STATE_SUSPENDED
was moved into xhci_suspend in 3.8.

commit 41e7e056cdc662f704fa9262e5c6e213b4ab45dd upstream.
If hot and warm reset fails, or a port remains in the Compliance Mode,
the USB core needs to be able to disable a USB 3.0 port. Unlike USB 2.0
ports, once the port is placed into the Disabled link state, it will not
report any new device connects. To get device connect notifications, we
need to put the link into the Disabled state, and then the RxDetect
state.
The xHCI driver needs to atomically clear all change bits on USB 3.0
port disable, so that we get Port Status Change Events for future port
changes. We could technically do this in the USB core instead of in the
xHCI roothub code, since the port state machine can't advance out of the
disabled state until we set the link state to RxDetect. However,
external USB 3.0 hubs don't need this code. They are level-triggered,
not edge-triggered like xHCI, so they will continue to send interrupt
events when any change bit is set. Therefore it doesn't make sense to
put this code in the USB core.
This patch is part of a series to fix several reports of infinite loops
on device enumeration failure. This includes John, when he boots with
a USB 3.0 device (Roseweil eusb3 enclosure) attached to his NEC 0.96
host controller. The fix requires warm reset support, so it does not
make sense to backport this patch to stable kernels without warm reset
support.
This patch should be backported to kernels as old as 3.2, contain the
commit ID 75d7cf72ab9fa01dc70877aa5c68e8ef477229dc "usbcore: refine warm

commit 68e5254adb88bede68285f11fb442a4d34fb550c upstream.
xhci_alloc_segments_for_ring() builds a list of xhci_segments and links
the tail to head at the end (forming a ring). When it bails out for OOM
reasons half-way through, it tries to destroy its half-built list with
xhci_free_segments_for_ring(), even though it is not a ring yet. This
causes a null-pointer dereference upon hitting the last element.
Furthermore, one of its callers (xhci_ring_alloc()) mistakenly believes
the output parameters to be valid upon this kind of OOM failure, and
calls xhci_ring_free() on them. Since the (incomplete) list/ring should
already be destroyed in that case, this would lead to a use after free.
This patch fixes those issues by having xhci_alloc_segments_for_ring()
destroy its half-built, non-circular list manually and destroying the
invalid struct xhci_ring in xhci_ring_alloc() with a plain kfree().
This patch should be backported to kernels as old as 2.6.31, that
contains the commit 0ebbab37422315a5d0cb29792271085bafdf38c0 "USB: xhci:

A separate patch will need to be developed for kernels older than 3.4,
since the ring allocation code was refactored in that kernel.

commit 4525c0a10dff7ad3669763c28016c7daffc3900e upstream.
The xHCI 1.0 specification made a change to the TD Size field in TRBs.
The value is now the number of packets that remain to be sent in the TD,
not including this TRB. The TD Size value for the last TRB in a TD must
always be zero.
The xHCI function xhci_v1_0_td_remainder() attempts to calculate this,
but it gets it wrong. First, it erroneously reuses the old
xhci_td_remainder function, which will right shift the value by 10. The
xHCI 1.0 spec as of June 2011 says nothing about right shifting by 10.
Second, it does not set the TD size for the last TRB in a TD to zero.
Third, it uses roundup instead of DIV_ROUND_UP. The total packet count
is supposed to be the total number of bytes in this TD, divided by the
max packet size, rounded up. DIV_ROUND_UP is the right function to use
in that case.
With the old code, a TD on an endpoint with max packet size 1024 would
be set up like so:
TRB 1, TRB length = 600 bytes, TD size = 0
TRB 1, TRB length = 200 bytes, TD size = 0
TRB 1, TRB length = 100 bytes, TD size = 0
With the new code, the TD would be set up like this:
TRB 1, TRB length = 600 bytes, TD size = 1
TRB 1, TRB length = 200 bytes, TD size = 1
TRB 1, TRB length = 100 bytes, TD size = 0

commit 392a07ae3316f2b90b39ce41e66d6f6b5c95de90 upstream.
David reports that at drivers/usb/host/xhci.c:2257:
static bool xhci_is_sync_in_ep(unsigned int ep_type)
{
return (ep_type == ISOC_IN_EP || ep_type != INT_IN_EP);
}
The static analyser cppcheck says
[linux-3.7-rc2/drivers/usb/host/xhci.c:2257]: (style) Redundant condition: If ep_type == 5, the comparison ep_type != 7 is always true.
Maybe the original programmer intention was something like
static bool xhci_is_sync_in_ep(unsigned int ep_type)
{
return (ep_type == ISOC_IN_EP || ep_type == INT_IN_EP);
}
Fix this.

commit 2656a9abcf1ec8dd5fee6a75d6997a0f2fa0094e upstream.
This patch (as1632b) fixes a bug in ehci-hcd. The USB core uses
urb->hcpriv to determine whether or not an URB is active; host
controller drivers are supposed to set this pointer to a non-NULL
value when an URB is queued. However ehci-hcd sets it to NULL for
isochronous URBs, which defeats the check in usbcore.
In itself this isn't a big deal. But people have recently found that
certain sequences of actions will cause the snd-usb-audio driver to
reuse URBs without waiting for them to complete. In the absence of
proper checking by usbcore, the URBs get added to their endpoint list
twice. This leads to list corruption and a system freeze.
The patch makes ehci-hcd assign a meaningful value to urb->hcpriv for
isochronous URBs. Improving robustness always helps.

commit bba18e33f25072ebf70fd8f7f0cdbf8cdb59a746 upstream.
Ali reports that plugging a device into the Fresco Logic xHCI host with
PCI device ID 1400 produces an IRQ error:
do_IRQ: 3.176 No irq handler for vector (irq -1)
Other early Fresco Logic host revisions don't support MSI, even though
their PCI config space claims they do. Extend the quirk to disabling
MSI to this chipset revision. Also enable the short transfer quirk,
since it's likely this revision also has that quirk, and it should be
harmless to enable.

commit 50ce5c0683aa83eb161624ea89daa5a9eee0c2ce upstream.
This patch (as1636) is a partial workaround for a hardware bug
affecting OHCI controllers by NVIDIA at least, maybe others too. When
the controller retires a Transfer Descriptor, it is supposed to add
the TD onto the Done Queue. But sometimes this doesn't happen, with
the result that ohci-hcd never realizes the corresponding transfer has
finished. Symptoms can vary; a typical result is that USB audio stops
working after a while.
The patch works around the problem by recognizing that TDs are always
processed in order. Therefore, if a later TD is found on the Done
Queue than all the earlier TDs for the same endpoint must be finished
as well.
Unfortunately this won't solve the problem in cases where the missing
TD is the last one in the endpoint's queue. A complete fix would
require a signficant amount of change to the driver.

Coverity complains that xhci_evaluate_context_result() is missing a
break statement after the COMP_EBADSLT switch case. It's not a big
deal, since we wanted to return the same error code as the case
statement below it does. The end result would be one that a Slot
Disabled error completion code would also print the warning message
associated with a Context State error code. No other bad behavior would
result.
It's not worth backporting to stable kernels, since it only fixes an
issue with too much debugging.

The command cancellation code doesn't check whether find_trb_seg()
couldn't find the segment that contains the TRB to be canceled. This
could cause a NULL pointer deference later in the function when next_trb
is called. It's unlikely to happen unless something is wrong with the
command ring pointers, so add some debugging in case it happens.

ehci_fsl_setup_phy is supposed to return an int, but had a void return
value in the case of controller_ver being invalid.
Introduced by commit 3735ba8db8e6 ("powerpc/usb: fix bug of CPU hang
when missing USB PHY clock"), which missed one return.

Device-tree probed devices don't get a dev.dma_mask set. This patch
sets a default 32bit mask on arch-vt8500 when using devicetree.
Without this patch, arch-vt8500 cannot detect ehci attached devices.

The __devinit section is going away soon, but while it's
still there, we get a correct warning about
ehci_orion_conf_mbus_windows being discarded before
its caller, so it should be marked __devinit rather than
__init.
Without this patch, building dove_defconfig results in:
WARNING: drivers/usb/host/built-in.o(.devinit.text+0x8a4): Section mismatch in reference from the function ehci_orion_drv_probe() to the function .init.text:ehci_orion_conf_mbus_windows()
The function __devinit ehci_orion_drv_probe() references
a function __init ehci_orion_conf_mbus_windows().
If ehci_orion_conf_mbus_windows is only used by ehci_orion_drv_probe then
annotate ehci_orion_conf_mbus_windows with a matching annotation.

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
Tejun pointed out a few of them, I fixed a couple more.

Pull ARM soc multiplatform enablement from Olof Johansson:
"This is a pretty significant branch. It's the introduction of the
first multiplatform support on ARM, and with this (and the later
branch) merged, it is now possible to build one kernel that contains
support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
platforms will be convered over in the next few releases.
Two critical last things had to be done for this to be practical and
possible:
* Today each platform has its own include directory under
mach-<mach>/include/mach/*, and traditionally that is where a lot
of driver/platform shared definitions have gone, such as platform
data structures. They now need to move out to a common location
instead, and this branch moves a large number of those out to
include/linux/platform_data.
* Each platform used to list the device trees to compile for its
boards in mach-<mach>/Makefile.boot.
Both of the above changes will mean that there are some merge
conflicts to come (and some to resolve here). It's a one-time move
and once it settles in, we should be good for quite a while. Sorry
for the overhead."
Fix conflicts as per Olof.

Pull ARM soc general cleanups from Olof Johansson:
"This is a large branch that contains a handful of different cleanups:
- Fixing up the I/O space remapping on PCI on ARM. This is a series
from Rob Herring that restructures how all pci devices allocate I/O
space, and it's part of the work to allow multiplatform kernels.
- A number of cleanup series for OMAP, moving and removing some
headers, sparse irq rework and in general preparation for
multiplatform.
- Final removal of all non-DT boards for Tegra, it is now
device-tree-only!
- Removal of a stale platform, nxp4008. It's an old mobile chipset
that is no longer in use, and was very likely never really used
with a mainline kernel. We have not been able to find anyone
interested in keeping it around in the kernel.
- Removal of the legacy dmaengine driver on tegra
+ A handful of other things that I haven't described above."

removed)

[ 7.810000] Kernel panic - not syncing: Fatal exception in interrupt
Commit 6fffb77c (USB: ohci-at91: fix PIO handling in relation with number of
ports) started setting unused pins to EINVAL. But this exposed a bug in the
ohci_hcd_at91_overcurrent_irq function where the gpio was used without being
checked to see if it is valid.
This patches fixed the issue by adding the gpio valid check.

xHCI bug fixes for 3.7
Hi Greg,
Here's three small bug fixes for 3.7. They fix a NULL pointer deference
and lost USB device unplug events, as well as making sure the xHCI
driver doesn't prevent system suspend.

When a device with an isochronous endpoint is behind a hub plugged into
the Intel Panther Point xHCI host controller, and the driver submits
multiple frames per URB, the xHCI driver will set the Block Event
Interrupt (BEI) flag on all but the last TD for the URB. This causes
the host controller to place an event on the event ring, but not send an
interrupt. When the last TD for the URB completes, BEI is cleared, and
we get an interrupt for the whole URB.
However, under a Panther Point xHCI host controller, if the parent hub
is unplugged when one or more events from transfers with BEI set are on
the event ring, a port status change event is placed on the event ring,
but no interrupt is generated. This means URBs stop completing, and the
USB device disconnect is not noticed. Something like a USB headset will
cause mplayer to hang when the device is disconnected.
If another transfer is sent (such as running `sudo lsusb -v`), the next
transfer event seems to "unstick" the event ring, the xHCI driver gets
an interrupt, and the disconnect is reported to the USB core.
The fix is not to use the BEI flag under the Panther Point xHCI host.
This will impact power consumption and system responsiveness, because
the xHCI driver will receive an interrupt for every frame in all
isochronous URBs instead of once per URB.
Intel chipset developers confirm that this bug will be hit if the BEI
flag is used on any endpoint, not just ones that are behind a hub.
This patch should be backported to kernels as old as 3.0, that contain
the commit 69e848c2090aebba5698a1620604c7dccb448684 "Intel xhci: Support

PHY_CLK_VALID bit doesn't work properly with UTMI PHY.
e.g. This bit is always zero on P5040, etc.
There is no need to check this bit for UTMI PHY, just keep
checking for ULPI PHY to prevent system hanging.
This patch should be squashed into previous commit 3735ba8db8e6e

In 71c731a: usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware
when extracting DMI strings (vendor or product_name) to mark them as quirk
we may get NULL pointer in case of non-x86 systems which won't define
CONFIG_DMI. Hence susbsequent strstr() calls crash while driver probing.
So, returning 'false' here in case we get a NULL vendor or product_name.
This is tested with ARM (exynos) system.
This patch should be backported to stable kernels as old as 3.6, that
contain the commit 71c731a296f1b08a3724bd1b514b64f1bda87a23 "usb: host:

The Intel XHCI specification says that after clearing the run/stop bit
the controller may take up to 16ms to halt. We've seen a device take
14ms, which with the current timeout of 10ms causes the kernel to
abort the suspend. Increasing the timeout to the recommended value
fixes the problem.
This patch should be backported to kernels as old as 2.6.37, that
contain the commit 5535b1d5f8885695c6ded783c692e3c0d0eda8ca "USB: xHCI:

[ 7.810000] Kernel panic - not syncing: Fatal exception in interrupt
Commit 6fffb77c (USB: ohci-at91: fix PIO handling in relation with number of
ports) started setting unused pins to EINVAL. But this exposed a bug in the
ohci_hcd_at91_overcurrent_irq function where the gpio was used without being
checked to see if it is valid.
This patches fixed the issue by adding the gpio valid check.

Add support for USB controller version 2.4

This patch (as1606) converts two warning messages in the ehci-hcd
driver to debug messages, and adds a little extra information to each.
The log messages occur when an EHCI controller takes too long (more
than 20 ms) to turn its async or periodic schedule on or off. If this
happens at all, it's liable to happen quite often and there's no point
spamming the system log with these warnings. Furthermore, there's
nothing much we can do about it when the problem happens.

This patch (as1605) removes a useless test from the EHCI debugfs
code. There's no point checking whether p.qh is non-NULL; we already
know it is and in any case it gets dereferenced aerlier in the
function.
The useless test was identified by smatch.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup
From Tony Lindgren:
This branch contains mostly scripted changes to make omap
header files local where possible to get us closer to supporting
the ARM single zImage. After these changes mach includes are
pretty much out of the way for omap2+, but still lots of manual
work remains to sort through the remaining plat includes.

ARM: tegra: switch to dmaengine
The Tegra code-base has contained both a legacy DMA and a dmaengine
driver since v3.6-rcX. This series flips Tegra's defconfig to enable
dmaengine rather than the legacy driver, and removes the legacy driver
and all client code.
* tag 'tegra-for-3.7-dmaengine' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:
ASoC: tegra: remove support of legacy DMA driver based access
spi: tegra: remove support of legacy DMA driver based access
ARM: tegra: apbio: remove support of legacy DMA driver based access
ARM: tegra: dma: remove legacy APB DMA driver
ARM: tegra: config: enable dmaengine based APB DMA driver
+ sync to 3.6-rc6

We are moving omap2+ to use the device tree based pinctrl-single.c
and will be removing the old mux framework. This will remove the
omap1 specific parts from plat-omap.
