c02cecb92e ARM: orion: move platform_data definitions
Platform data for device drivers should be defined in
include/linux/platform_data/*.h, not in the architecture
and platform specific directories.

This moves such data out of the orion include directories

8f057d7bca gpu/mfd/usb: Fix USB randconfig problems
Fix config warning:

warning: ( ... && DRM_USB) selects USB which has unmet direct dependencies
(USB_SUPPORT && USB_ARCH_HAS_HCD)

and build error:
ERROR: "usb_speed_string" [drivers/usb/core/usbcore.ko] undefined!

by adding the missing dependency on USB_ARCH_HAS_HCD to DRM_UDL and DRM_USB.

This exposes:
drivers/video/Kconfig:36:error: recursive dependency detected!
drivers/video/Kconfig:36:       symbol FB is selected by DRM_KMS_HELPER
drivers/gpu/drm/Kconfig:28:     symbol DRM_KMS_HELPER is selected by DRM_UDL

drivers/video/Kconfig:86:       symbol FB_DDC is selected by FB_CYBER2000_DDC
drivers/video/Kconfig:385:      symbol FB_CYBER2000_DDC depends on FB_CYBER2000
drivers/video/Kconfig:373:      symbol FB_CYBER2000 depends on FB

which is due to drivers/usb/Kconfig:
config USB_ARCH_HAS_OHCI
	...
	default y if ARCH_PNX4008 && I2C

Fix by dropping I2C from the above dependency; logic is that this is not a
platform dependency but a configuration dependency: the _architecture_ still
supports USB even is I2C is not selected.

This exposes:
drivers/video/Kconfig:36:error: recursive dependency detected!

drivers/gpio/Kconfig:35:        symbol GPIOLIB is selected by FB_VIA
drivers/video/Kconfig:1560:     symbol FB_VIA depends on FB

which can be fixed by having MFD_TC6393XB select GPIOLIB instead of depending on
it.

99f347caa4 USB: CDC ACM: Fix NULL pointer dereference
If a device specifies zero endpoints in its interface descriptor,
the kernel oopses in acm_probe(). Even though that's clearly an
invalid descriptor, we should test wether we have all endpoints.
This is especially bad as this oops can be triggered by just
plugging a USB device in.

731879f8e3 USB: qcserial: fix port handling on Gobi 1K and 2K+
Bjorn's latest patchset does break Gobi 1K and 2K because on both
devices as it claims usb interface 0.  That's because usbif 0 is not
handled in the switch statement, and thus the if0 gets claimed when it
should not.  So let's just make things even simpler yet, and handle both
the 1K and 2K+ cases separately.  This patch should not affect the new
Sierra device support, because those devices are matched via
interface-specific matching and thus should never hit the composite
code.

b1b552a69b usb: gadget: u_ether: fix kworker 100% CPU issue with still used interfaces in eth_stop
This patch fixes an issue introduced by patch:

    72c973d usb: gadget: add usb_endpoint_descriptor to struct usb_ep

Without this patch we see a kworker taking 100% CPU, after this sequence:

- Connect gadget to a windows host
- load g_ether
- ifconfig up <ip>; ifconfig down; ifconfig up
- ping <windows host>

The "ifconfig down" results in calling eth_stop(), which will call
usb_ep_disable() and, if the carrier is still ok, usb_ep_enable():

         usb_ep_disable(link->in_ep);
         usb_ep_disable(link->out_ep);
         if (netif_carrier_ok(net)) {
                 usb_ep_enable(link->in_ep);
                 usb_ep_enable(link->out_ep);
         }

The ep should stay enabled, but will not, as ep_disable set the desc
pointer to NULL, therefore the subsequent ep_enable will fail. This leads
to permanent rescheduling of the eth_work() worker as usb_ep_queue()
(called by the worker) will fail due to the unconfigured endpoint.

We fix this issue by saving the ep descriptors and re-assign them before
usb_ep_enable().

ecc8a0cdca usb: host: tegra: fix warning messages in ehci_remove
Existing implementation of tegra_ehci_remove() calls
usb_put_hcd(hcd) first and then iounmap(hcd->regs).

usb_put_hcd() implementation calls hcd_release()
which frees up memory allocated for hcd.

As iounmap is trying to unmap hcd->regs, after hcd
getting freed up, warning messages were observed during
unload of USB.

Hence fixing it.

032129cb03 usb: usb_wwan: resume/suspend can be called after port is gone
We cannot unconditionally access any usb-serial port specific
data from the interface driver.  Both supending and resuming
may happen after the port has been removed and portdata is
freed.

Treat ports with no portdata as closed ports to avoid a NULL
pointer dereference on resume.  No need to kill URBs for
removed ports on suspend, avoiding the same NULL pointer
reference there.

d5fd650cfc usb: serial: prevent suspend/resume from racing against probe/remove
Some usb-serial drivers may access port data in their suspend/
resume functions. Such drivers must always verify the validity
of the data as both suspend and resume can be called both before
usb_serial_device_probe and after usb_serial_device_remove.

But the port data may be invalidated during port_probe and
port_remove. This patch prevents the race against suspend and
resume by disabling suspend while port_probe or port_remove is
running.

a1028f0abf usb: usb_wwan: replace release and disconnect with a port_remove hook
Doing port specific cleanup in the .port_remove hook is a
lot simpler and safer than doing it in the USB driver
.release or .disconnect methods. The removal of the port
from the usb-serial bus will happen before the USB driver
cleanup, so we must be careful about accessing port specific
driver data from any USB driver functions.

This problem surfaced after the commit

 0998d0631 device-core: Ensure drvdata = NULL when no driver is bound

which turned the previous unsafe access into a reliable NULL
pointer dereference.

71a5e61b81 usb: chipidea: fix and improve dependencies if usb host or gadget support is built as module
Since commit "5e0aa49 usb: chipidea: use generic map/unmap routines",
the udc part of the chipidea driver needs the generic usb gadget helper
functions. If the chipidea driver with udc support is built into the
kernel and usb gadget is built a module, the linking of the kernel
fails with:

drivers/built-in.o: In function `_hardware_dequeue':
drivers/usb/chipidea/udc.c:527:
    undefined reference to `usb_gadget_unmap_request'
drivers/usb/chipidea/udc.c:1269:
    undefined reference to `usb_gadget_unmap_request'
drivers/usb/chipidea/udc.c:1821:
    undefined reference to `usb_del_gadget_udc'

    undefined reference to `usb_gadget_map_request'
drivers/usb/chipidea/udc.c:1774:
    undefined reference to `usb_add_gadget_udc'

This patch changes the dependencies, so that udc support can only be
activated if the linux gadget support (USB_GADGET) is builtin or both
chipidea driver and USB_GADGET are modular. Same dependencies for the
chipidea host support and the linux host side USB support (USB).

While there, fix the indention of chipidea the help text.

e95829f474 xhci: Switch PPT ports to EHCI on shutdown.
The Intel desktop boards DH77EB and DH77DF have a hardware issue that
can be worked around by BIOS.  If the USB ports are switched to xHCI on
shutdown, the xHCI host will send a spurious interrupt, which will wake
the system.  Some BIOS will work around this, but not all.

The bug can be avoided if the USB ports are switched back to EHCI on
shutdown.  The Intel Windows driver switches the ports back to EHCI, so
change the Linux xHCI driver to do the same.

Unfortunately, we can't tell the two effected boards apart from other
working motherboards, because the vendors will change the DMI strings
for the DH77EB and DH77DF boards to their own custom names.  One example
is Compulab's mini-desktop, the Intense-PC.  Instead, key off the
Panther Point xHCI host PCI vendor and device ID, and switch the ports
over for all PPT xHCI hosts.

The only impact this will have on non-effected boards is to add a couple
hundred milliseconds delay on boot when the BIOS has to switch the ports
over from EHCI to xHCI.

This patch should be backported to kernels as old as 3.0, that contain
the commit 69e848c209 "Intel xhci: Support
EHCI/xHCI port switching."

50d0206fca xhci: Fix bug after deq ptr set to link TRB.
This patch fixes a particularly nasty bug that was revealed by the ring
expansion patches.  The bug has been present since the very beginning of
the xHCI driver history, and could have caused general protection faults
from bad memory accesses.

The first thing to note is that a Set TR Dequeue Pointer command can
move the dequeue pointer to a link TRB, if the canceled or stalled
transfer TD ended just before a link TRB.  The function to increment the
dequeue pointer, inc_deq, was written before cancellation and stall
support was added.  It assumed that the dequeue pointer could never
point to a link TRB.  It would unconditionally increment the dequeue
pointer at the start of the function, check if the pointer was now on a
link TRB, and move it to the top of the next segment if so.

This means that if a Set TR Dequeue Point command moved the dequeue
pointer to a link TRB, a subsequent call to inc_deq() would move the
pointer off the segment and into la-la-land.  It would then read from
that memory to determine if it was a link TRB.  Other functions would
often call inc_deq() until the dequeue pointer matched some other
pointer, which means this function would quite happily read all of
system memory before wrapping around to the right pointer value.

Often, there would be another endpoint segment from a different ring
allocated from the same DMA pool, which would be contiguous to the
segment inc_deq just stepped off of.  inc_deq would eventually find the
link TRB in that segment, and blindly move the dequeue pointer back to
the top of the correct ring segment.

The only reason the original code worked at all is because there was
only one ring segment.  With the ring expansion patches, the dequeue
pointer would eventually wrap into place, but the dequeue segment would
be out-of-sync.  On the second TD after the dequeue pointer was moved to
a link TRB, trb_in_td() would fail (because the dequeue pointer and
dequeue segment were out-of-sync), and this message would appear:

ERROR Transfer event TRB DMA ptr not part of current TD

This fixes bugzilla entry 4333 (option-based modem unhappy on USB 3.0
port: "Transfer event TRB DMA ptr not part of current TD", "rejecting
I/O to offline device"),

	https://bugzilla.kernel.org/show_bug.cgi?id=43333

and possibly other general protection fault bugs as well.

This patch should be backported to kernels as old as 2.6.31.  A separate
patch will be created for kernels older than 3.4, since inc_deq was
modified in 3.4 and this patch will not apply.

xhci_hcd 0000:03:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk?

We think his Etron xHCI host controller may have the same buggy behavior
as the Fresco Logic xHCI host.  When a short transfer is received, the
host will mark the transfer as successfully completed when it should be
marking it with a short completion.

Fix this by turning on the XHCI_TRUST_TX_LENGTH quirk when the Etron
host is discovered.  Note that Gary has revision 1, but if Etron fixes
this bug in future revisions, the quirk will have no effect.

This patch should be backported to kernels as old as 2.6.36, that
contain a backported version of commit
1530bbc627 "xhci: Add new short TX quirk
for Fresco Logic host."

22ceac1912 xhci: Increase reset timeout for Renesas 720201 host.
The NEC/Renesas 720201 xHCI host controller does not complete its reset
within 250 milliseconds.  In fact, it takes about 9 seconds to reset the
host controller, and 1 second for the host to be ready for doorbell
rings.  Extend the reset and CNR polling timeout to 10 seconds each.

This patch should be backported to kernels as old as 2.6.31, that
contain the commit 66d4eadd8d "USB: xhci:

0614002bb5 netvm: propagate page->pfmemalloc from skb_alloc_page to skb
The skb->pfmemalloc flag gets set to true iff during the slab allocation
of data in __alloc_skb that the the PFMEMALLOC reserves were used.  If
page splitting is used, it is possible that pages will be allocated from
the PFMEMALLOC reserve without propagating this information to the skb.
This patch propagates page->pfmemalloc from pages allocated for fragments
to the skb.

It works by reintroducing and expanding the skb_alloc_page() API to take
an skb.  If the page was allocated from pfmemalloc reserves, it is
automatically copied.  If the driver allocates the page before the skb, it
should call skb_propagate_pfmemalloc() after the skb is allocated to
ensure the flag is copied properly.

Failure to do so is not critical.  The resulting driver may perform slower
if it is used for swap-over-NBD or swap-over-NFS but it should not result
in failure.

This is based on emperical testing on various USB debug ports on

In particular, commit 2761a63945 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).

I left that part of commit 2761a63945 just undone.
