H Hartley Sweeten a26f4dd0eb staging: comedi: rtd520: ioremap'ed addresses are resource_size_t
As mentioned by Ian Abbott, the pci address passed to ioremap
should be a resource_size_t not an unsigned long. Use a local
variable of that type to hold the pci_resource_start() that is
passed to ioremp().

Set the dev->iobase to a dummy non-zero value so that the "detach"
can use it as a flag to know that comedi_pci_disable() needs to
be called.

As mentioned by Ian Abbott, the comedi pci drivers that try to

Greg Kroah-Hartman 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).

Sarah Sharp 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.

Sarah Sharp 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

Oliver Hartkopp 035534ed33 canfd: remove redundant CAN FD flag
The first idea of the CAN FD implementation started with a new struct
canfd_frame to be used for both CAN FD frames and legacy CAN frames.
The now mainlined implementation supports both CAN frame types simultaneously
and distinguishes them only by their required sizes: CAN_MTU and CANFD_MTU.

Only the struct canfd_frame contains a flags element which is needed for the
additional CAN FD information. As CAN FD implicitly means that the 'Extened
Data Length' mode is enabled the formerly defined CANFD_EDL bit became
redundant and also confusing as an unset bit would be an error and would
always need to be tested.

This patch removes the obsolete CANFD_EDL bit and clarifies the documentation
for the use of struct canfd_frame and the CAN FD relevant flags.

Stefan Assmann 119b0e0351 igb: add delay to allow igb loopback test to succeed on 8086:10c9
Some 8086:10c9 NICs have a problem completing the ethtool loopback test.
The result looks like this:

ethtool -t eth1
The test result is FAIL
The test extra info:
Register test  (offline)         0
Eeprom test    (offline)         0
Interrupt test (offline)         0
Loopback test  (offline)         13
Link test   (on/offline)         0

A bisect clearly points to commit a95a07445e.
However that seems to only trigger the bug. While adding some printk the
problem disappeared, so this might be a timing issue. After some trial and
error I discovered that adding a small delay just before igb_write_phy_reg()
in igb_integrated_phy_loopback() allows the loopback test to succeed.
I was unable to figure out the root cause so far but I expect it to be
somewhere in the following executing path
igb_integrated_phy_loopback
->igb_write_phy_reg_igp
  ->igb_write_phy_reg_mdic
    ->igb_acquire_phy_82575
      ->igb_acquire_swfw_sync_82575

The problem could only be observed on 8086:10c9 NICs so far and not all
of them show the behaviour. I did not restrict the workaround to this
type of NIC as it should do no harm to other igb NICs.

With the patch below the loopback test succeeded 500 times in a row
using a NIC that would otherwise fail.

Tushar Dave eca90f5504 e1000e: 82571 Tx Data Corruption during Tx hang recovery
A bus trace shows that while executing e1000e_down, TCTL is cleared except
for the PSP bit.  This occurs while in the middle of fetching a TSO packet
since the Tx packet buffer is full at that point. Before the device is
reset, the e1000_watchdog_task starts to run from the middle (it was
apparently pre-empted earlier, although that is not in the trace) and sets
TCTL.EN.  At that point, 82571 transmits the corrupted packet, apparently
because TCTL.MULR was cleared in the middle of fetching a packet, which is
forbidden.

Driver should just clear TCTL.EN in e1000_reset_hw_82571 instead of
clearing the entire register, so as not to change any settings in the
middle of fetching a packet.

Shawn Guo 7e6086d9e5 gpio/mxc: specify gpio base for device tree probe
Currently, unlike the non-DT probe where the gpio base is specified
with pdev->id, the DT probe uses the base dynamically allocated by
gpio core, which uses a completely different numbering scheme.  This
causes two issues to user space applications which access sysfs entry
/sys/class/gpio/gpioN.

* It breaks the compatibility with user space applications between
  non-DT and DT kernels.

* It's not intuitive and sometimes hard for users to map the Linux
  gpio number to the actual hardware pin.

Use alias to identify the gpio port/bank, and then the gpio base
can be specified with port id to solve above issues.  If alias is not
defined in device tree, the base number dynamically allocated by gpio
core will be used.

But the caller expects it to return either a pointer or NULL.  Replace
the NULL check with IS_ERR() check.

If a fixed TEI is used, the initial state of the layer 2 statmachine need to be
4 (TEI assigned). This was true only for Point to Point connections, but not
for the other fixed TEIs. It was not found before, because usually only the
TEI 0 is used as fixed TEI for PtP mode, but if you try X31 packet mode
connections with SAPI 16, TEI 1, it did fail.

Johannes Berg 50e2a30cf6 iwlwifi: disable greenfield transmissions as a workaround
There's a bug that causes the rate scaling to get stuck
when it has to use single-stream rates with a peer that
can do GF and SGI; the two are incompatible so we can't
use them together, but that causes the algorithm to not
work at all, it always rejects updates.

Disable greenfield for now to prevent that problem.

Daniel Drake 1f6fc43e62 cfg80211: process pending events when unregistering net device
libertas currently calls cfg80211_disconnected() when it is being
brought down. This causes an event to be allocated, but since the
wdev is already removed from the rdev by the time that the event
processing work executes, the event is never processed or freed.
http://article.gmane.org/gmane.linux.kernel.wireless.general/95666

Fix this leak, and other possible situations, by processing the event
queue when a device is being unregistered. Thanks to Johannes Berg for
the suggestion.

Hunt Xu 5ab3633d69 drm/i915: make rc6 in sysfs functions conditional
Commit 0136db586c merges rc6 information
into the power group. However, when compiled with CONFIG_PM not set,
modprobing i915 would taint since power_group_name is defined as NULL.

This patch makes these rc6 in sysfs functions conditional upon the
definition of the CONFIG_PM macro to avoid the above-mentioned problem.

Zach Brown fb6ccff667 fuse: verify all ioctl retry iov elements
Commit 7572777eef attempted to verify that
the total iovec from the client doesn't overflow iov_length() but it
only checked the first element.  The iovec could still overflow by
starting with a small element.  The obvious fix is to check all the
elements.

The overflow case doesn't look dangerous to the kernel as the copy is
limited by the length after the overflow.  This fix restores the
intention of returning an error instead of successfully copying less
than the iovec represented.

I found this by code inspection.  I built it but don't have a test case.
I'm cc:ing stable because the initial commit did as well.
