fdc6b38892 [media] cx24123: fix kernel oops due to missing parent pointer
When I try to set the TV standard to e.g. PAL on my Hauppauge WinTV-HVR3000 I get
the following oops:

I traced this to a NULL i2c_adapter parent pointer when cx24123 creates its own
i2c adapter. The acpi_i2c_install_space_handler function appeared in 3.17, so
that's probably why this hasn't been seen before.

bf3593d939 [media] vb2: fix vb2 state check when start_streaming fails
Commit bd994ddb2a (vb2: Fix stream start and
buffer completion race) broke the buffer state check in vb2_buffer_done.

So accept all three possible states there since I can no longer tell the
difference between vb2_buffer_done called from start_streaming or from
elsewhere.

Instead add a WARN_ON at the end of start_streaming that will check whether
any buffers were added to the done list, since that implies that the wrong
state was used as well.

23cd08c8f7 [media] videobuf2-core: add comments before the WARN_ON
Recently WARN_ON() calls have been added to warn if the driver is not
properly returning buffers to vb2 in start_streaming (if it fails) or
stop_streaming(). Add comments before those WARN_ON calls that refer
to the videobuf2-core.h header that explains what drivers are supposed
to do in these situations. That should help point developers in the
right direction if they see these warnings.

8ab17fc92e ACPI / hotplug: Generate online uevents for ACPI containers
Commit 46394fd01 (ACPI / hotplug: Move container-specific code out of
the core) removed the generation of "online" uevents for containers,
because "add" uevents are now generated for them automatically when
container system devices are registered.  However, there are user
space tools that need to be notified when the container and all of
its children have been enumerated, which doesn't happen any more.

For this reason, add a mechanism allowing "online" uevents to be
generated for ACPI containers after enumerating the container along
with all of its children.

Fixes: 46394fd01 (ACPI / hotplug: Move container-specific code out of the core)

6a40281ab5 sched: Fix end_of_stack() and location of stack canary for architectures using CONFIG_STACK_GROWSUP
Aaron Tomlin recently posted patches [1] to enable checking the
stack canary on every task switch. Looking at the canary code, I
realized that every arch (except ia64, which adds some space for
register spill above the stack) shares a definition of
end_of_stack() that makes it the first long after the
threadinfo.

For stacks that grow down, this low address is correct because
the stack starts at the end of the thread area and grows toward
lower addresses. However, for stacks that grow up, toward higher
addresses, this is wrong. (The stack actually grows away from
the canary.) On these archs end_of_stack() should return the
address of the last long, at the highest possible address for the stack.

I2C_CLKDIV register descripted in the previous version of
RK3x chip manual is incorrect. Plus 1 is required.

The correct formula:
- T(SCL_HIGH) = T(PCLK) * (CLKDIVH + 1) * 8
- T(SCL_LOW) = T(PCLK) * (CLKDIVL + 1) * 8
- (SCL Divsor) = 8 * ((CLKDIVL + 1) + (CLKDIVH + 1))
- SCL = PCLK / (CLK Divsor)

It will be updated to the latest version of chip manual.

Currently the i2c-tegra bus driver prepares, enables

This causes locking problems when doing I2C transfers
from clock notifiers; see
http://lists.infradead.org/pipermail/linux-arm-kernel/2014-July/268653.html

This patch moves clk_prepare/unprepare and clk_set_rate calls to
the probe function, leaving only clk_enable/disable to be
done on each transfer. This solves the locking issue.

c80b4495c6 USB: storage: Add quirks for Entrega/Xircom USB to SCSI converters
This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB-
SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The
US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI
chain to be accessed. Without it only the (single) device with SCSI ID 0
can be used.

The standalone converter sold by Entrega had model number U1-SC25. Xircom
acquired Entrega and re-branded the product line PortGear. The PortGear USB
to SCSI Converter (model PGSCSI) is internally identical to the Entrega
product, but later models may use a different USB ID. The Entrega-branded
units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and
Macintosh drivers also support 085A:0028.

Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac
(8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as
a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may
have initially used the same ID as the standalone U1-SC25 (1645:0007), but
later production used 085A:0026.

My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133
probably also exist.

This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows
driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I
couldn't find any mention of that actually existing in the wild; perhaps it
was cancelled before release?

b6a3ed6779 USB: storage: Add quirk for Ariston Technologies iConnect USB to SCSI adapter
Hi,

The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g.
iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM
Microsystems chips. Only the connectors differ; both have the same USB ID.
The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other
than 0.

I don't have one of these, but based on the other entries for Shuttle/
SCM-based converters this patch is very likely correct. I used 0x0000 and
0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which
bcdDevice value the products use.

7312b5ddd4 USB: EHCI: unlink QHs even after the controller has stopped
Old code in ehci-hcd tries to expedite disabling endpoints after the
controller has stopped, by destroying the endpoint's associated QH
without first unlinking the QH.  This was necessary back when the
driver wasn't so careful about keeping track of the controller's
state.

But now we are careful about it, and the driver knows that when the
controller isn't running, no unlinking delay is needed.  Furthermore,
skipping the unlink step will trigger a BUG() in qh_destroy() when the
preceding QH is released, because the link pointer will be non-NULL.

Removing the lines that skip the unlinking step and go directly to
QH_STATE_IDLE fixes the problem.

====================
pull-request: can 2014-09-18

this is a pull request of 8 patches for current net.

A patch by Roger Quadros for the c_can driver fixes the swapped parameters of
the c_can_hw_raminit_ti() function. Oliver Hartkopp adds the missing PCI ids to
the peak_pci driver to support the single channel PCAN ExpressCard 34 adapter.
David Dueck converts the at91_can driver to use proper clock handling
functions. Then there are 5 patches by David Jander and me which fix several
mailbox related problems in the flexcan driver.

9b67aa4a82 openvswitch: restore OVS_FLOW_CMD_NEW notifications
Since commit fb5d1e9e12 ("openvswitch: Build flow cmd netlink reply only if needed."),
the new flows are not notified to the listeners of OVS_FLOW_MCGROUP.

This commit fixes the problem by using the genl function, ie
genl_has_listerners() instead of netlink_has_listeners().

0d0162e7a3 net: allow macvlans to move to net namespace
I cannot move a macvlan interface created on top of a bonding interface
to a different namespace:

% ip netns add dummy0
% ip link add link bond0 mac0 type macvlan
% ip link set mac0 netns dummy0
RTNETLINK answers: Invalid argument
%

The problem seems to be that commit f939981492 ("bonding: Don't allow
bond devices to change network namespaces.") sets NETIF_F_NETNS_LOCAL
on bonding interfaces, and commit 797f87f83b ("macvlan: fix netdev
feature propagation from lower device") causes macvlan interfaces
to inherit its features from the lower device.

NETIF_F_NETNS_LOCAL should not be inherited from the lower device
by a macvlan.
Patch tested on 3.16.

8400dd029e 3c59x: Fix bad offset spec in skb_frag_dma_map
Recently aded the use of skb_frag_dma_map to 3c59x, but didn't realize it
automatically included the frag_offset internally, as well as provided an option
to specify an extra offset in the parameter list.  We need to specify an offset
of 0 in the parameter list to avoid skb corruption that results in lost
connections.

6f2b6a3005 3c59x: Add dma error checking and recovery
Noted that 3c59x has no checks on transmit for failed DMA mappings, and no
ability to unmap fragments when a single map fails in the middle of a transmit.
This patch provides error checking to ensure that dma mappings work properly,
and unrolls an skb mapping if a fragmented skb transmission has a mapping
failure to prevent leaks.

f6f2332dce sparc: bpf_jit: fix support for ldx/stx mem and SKF_AD_VLAN_TAG
fix several issues in sparc BPF JIT compiler.

ldx/stx related:
. classic BPF instructions that access mem[] slots were not setting
  SEEN_MEM flag, so stack wasn't allocated. Fix that by advertising
  correct flags

. LDX/STX instructions were missing SEEN_XREG, so register value
  could have leaked to user space. Fix it.

. since stack for mem[] slots is allocated with 'sub %sp' instead
  of 'save %sp', use %sp as base register instead of %fp.

. ldx mem[0] means first slot in classic BPF which should have
  -4 offset instead of 0.

. sparc64 needs 2047 stack bias as per ABI to access stack

. emit_stmem() was using LD32I macro instead of ST32I

SKF_AD_VLAN_TAG* related:
. SKF_AD_VLAN_TAG_PRESENT must return 1 or 0 instead of '> 0' or 0
  as per classic BPF de facto standard

. SKF_AD_VLAN_TAG needs to mask the field correctly
