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.

Fixes the following Oops:

This commit 354ab8567a titled
"Fix OMAP EHCI suspend/resume failure (i693)" is causing
the usb hub and device detection fails in beagle XM
causeing NFS not functional. This affects the core retention too.
The same commit logic needs to be revisted adhering to hwmod and
device tree framework.
for now, this commit id 354ab8567a
titled "Fix OMAP EHCI suspend/resume failure (i693)" reverted.

This patch is validated on BeagleXM with NFS support over
usb ethernet and USB mass storage and other device detection.

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'
drivers/usb/chipidea/udc.c:443:
    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."

Hi Greg,
 
 Here's four patches for 3.6.  Most are marked for stable as well.
 
 The first one makes the xHCI driver load properly on newer Rensas hosts.
 The next two fix issues with the Etron host incorrectly marking short
 transfers as successful, and avoiding log warning spam for hosts that
 make the same mistake.
 
 The last patch fixes a really nasty xHCI driver bug that could cause
 general protection faults when devices stall transfers.

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.

010ccce0fa usb: fixes for v3.6-rc1
Here are three fixes for v3.6-rc1. All on the MUSB driver and
 quite obvious. First there's a Kconfig change which was missed
 earlier, then there is a fix for the usage of the resource name
 and lastly a fix for pm_runtime usage and device initialization.
 
 The last fix is rather critical as it can end up in situations
 where we try to access device's register with clocks disabled,
 which will cause a Data Abort exception (on ARM).

8202ce2e29 xhci: Rate-limit XHCI_TRUST_TX_LENGTH quirk warning.
When we encounter an xHCI host that needs the XHCI_TRUST_TX_LENGTH
quirk, the xHCI driver ends up spewing messages about the quirk into
dmesg every time a short packet occurs.  Change the xHCI driver to
rate-limit such warnings.

5cb7df2b2d xhci: Add Etron XHCI_TRUST_TX_LENGTH quirk.
Gary reports that with recent kernels, he notices more xHCI driver
warnings:

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."

The NEC/Renesas 720201 xHCI host controller does not complete its reset

bfdf85dfce ARM: arm-soc: cpuidle enablement for OMAP
Coupled cpuidle was meant to merge for 3.5 through Len Brown's tree, but
 didn't go in because the pull request ended up rejected. So it just got
 merged, and we got this staged branch that enables the coupled cpuidle
 code on OMAP.
 
 With a stable git workflow from the other maintainer we could have staged
 this earlier, but that wasn't the case so we have had to merge it late.
 
 The alternative is to hold it off until 3.7 but given that the code is
 well-isolated to OMAP and they are eager to see it go in, I didn't push
 back hard in that direction.

Merge tag 'ecryptfs-3.6-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs

Pull ecryptfs fixes from Tyler Hicks:
 - Fixes a bug when the lower filesystem mount options include 'acl',
   but the eCryptfs mount options do not
 - Cleanups in the messaging code
 - Better handling of empty files in the lower filesystem to improve
   usability.  Failed file creations are now cleaned up and empty lower
   files are converted into eCryptfs during open().
 - The write-through cache changes are being reverted due to bugs that
   are not easy to fix.  Stability outweighs the performance
   enhancements here.
 - Improvement to the mount code to catch unsupported ciphers specified
   in the mount options

* tag 'ecryptfs-3.6-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs:
  eCryptfs: check for eCryptfs cipher support at mount

8783b6e2b2 mm: remove node_start_pfn checking in new WARN_ON for now
Borislav Petkov reports that the new warning added in commit
88fdf75d1b ("mm: warn if pg_data_t isn't initialized with zero")
triggers for him, and it is the node_start_pfn field that has already
been initialized once.

The call trace looks like this:

  x86_64_start_kernel ->
    x86_64_start_reservations ->
    start_kernel ->
    setup_arch ->
    paging_init ->
    zone_sizes_init ->
    free_area_init_nodes ->
    free_area_init_node

and (with the warning replaced by debug output), Borislav sees

  On node 0 totalpages: 4193848
    DMA zone: 64 pages used for memmap
    DMA zone: 6 pages reserved
    DMA zone: 3890 pages, LIFO batch:0

5ef50c3bec ceph: simplify+fix atomic_open
The initial ->atomic_open op was carried over from the old intent code,
which was incomplete and didn't really work.  Replace it with a fresh
method.  In particular:

 * always attempt to do an atomic open+lookup, both for the create case
   and for lookups of existing files.
 * fix symlink handling by returning 1 to the VFS so that we can follow
   the link to its destination. This fixes a longstanding ceph bug (#2392).

a6dc77254b Merge branch 'dmaengine' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM DMA engine updates from Russell King:
 "This looks scary at first glance, but what it is is:
   - a rework of the sa11x0 DMA engine driver merged during the previous
     cycle, to extract a common set of helper functions for DMA engine
     implementations.
   - conversion of amba-pl08x.c to use these helper functions.
   - addition of OMAP DMA engine driver (using these helper functions),
     and conversion of some of the OMAP DMA users to use DMA engine.

  Nothing in the helper functions is ARM specific, so I hope that other
  implementations can consolidate some of their code by making use of
  these helpers.

  This has been sitting in linux-next most of the merge cycle, and has
  been tested by several OMAP folk.  I've tested it on sa11x0 platforms,
  and given it my best shot on my broken platforms which have the
  amba-pl08x controller.

  The last point is the addition to feature-removal-schedule.txt, which
  will have a merge conflict.  Between myself and TI, we're planning to
  remove the old TI DMA implementation next year."
