Pull networking fix from David Miller:
"This is a quick one commit pull request to cure the regression
introduced by the MSG_CMSG_COMPAT change."
(Background: commit 1be374a0518a completely broke 32-bit COMPAT handling
by not only disallowing MSG_CMSG_COMPAT from user APIs, but clearing it
in our own internal use too!)

net: Block MSG_CMSG_COMPAT in send(m)msg and recv(m)msg
This patch adds __sys_sendmsg and __sys_sendmsg as common helpers that accept
MSG_CMSG_COMPAT and blocks MSG_CMSG_COMPAT at the syscall entrypoints. It
also reverts some unnecessary checks in sys_socketcall.
Apparently I was suffering from underscore blindness the first time around.

Jonathan writes:
Second round of IIO fixes for the 3.10 cycle.
A couple of little bits and pieces, some delayed due to traveling.
1) A memory leak fix in the callback buffer.
2) Wrong exit path due to a return when it should have been a goto.
3) Bug in a mask value in ad4350
4) Reading the wrong value in raw to processed utility function.

when instead the form should have been

Here this causes a useful iio_device_put to be skipped.

Passing the value DMA_BIT_MASK(31) to dma_set_mask() causes the
dwc2-pci driver to sometimes fail (cannot enumerate the connected
device). Change it to DMA_BIT_MASK(32) instead, which is a more
sensible value anyway.

This reverts commit cfcec52e9781f08948c6eb98198d65c45be75a70.
This regresses a longstanding behaviour on X86 systems, which end up with
PCI serial ports moving between ttyS4 and ttyS0 when you bisect to opposite
sides of this commit, resulting in the need to constantly modify the console
setting in order to bisect across it.
Please revert, we can work on solving this for ARM platforms in a less
disruptive way.

Per some ZTE Linux drivers I found for the AC2716, the following patch
moves most ZTE CDMA devices from option to zte_ev. The blacklist stuff
that option does is not required with zte_ev, because it doesn't
implement any of the send_setup hooks which the blacklist suppressed.
I did not move the 2718 over because I could not find any ZTE Linux
drivers for that device, nor even any Windows drivers.

driven by the cypress_M8 module. Changes are:
- add VendorID ProductID to device tables
- skip unstable speed check because FRWD uses 115200bps
- skip reset at probe which is an issue workaround for this
particular device.

This patch reverts commit 3e619d04159be54b3daa0b7036b0ce9e067f4b5d
(USB: EHCI: fix bug in scheduling periodic split transfers). The
commit was valid -- it fixed a real bug -- but the periodic scheduler
in ehci-hcd is in such bad shape (especially the part that handles
split transactions) that fixing one bug is very likely to cause
another to surface. That's what happened in this case; the result was
choppy and noisy playback on certain 24-bit audio devices.
The only real fix will be to rewrite this entire section of code. My
next project...
This fixes https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1136110.
Thanks to Tim Richardson for extra testing and feedback, and to Joseph
Salisbury and Tyson Tan for tracking down the original source of the
problem.

xhci: Misc bug fixes for 3.10.
Hi Greg,
Here's four xHCI bug fixes that should be queued for 3.10.
The first two are generic bug fixes, and have been in my queue for a while
because I've been doing the OPW internship coordination. I suspect you'll be
seeing more pull requests from me now that the intern selection process is
almost over. :)
The last two patches fix a nasty kernel crash on resume from S3 for TI hosts
that have the compliance mode quirk. Tony has confirmed that the patches fix
the issue on the effected systems.
All four patches are marked for stable.

Some xHCI hosts contain a "redriver" from TI that silently drops port
status connect changes if the port slips into Compliance Mode. If the
port slips into compliance mode while the host is in D0, there will not
be a port status change event. If the port slips into compliance mode
while the host is in D3, the host will not send a PME. This includes
when the system is suspended (S3) or hibernated (S4).
If this happens when the system is in S3/S4, there is nothing software
can do. Other port status change events that would normally cause the
host to wake the system from S3/S4 may also be lost. This includes
remote wakeup, disconnects and connects on other ports, and overrcurrent
events. A decision was made to _NOT_ disable system suspend/hibernate
on these systems, since users are unlikely to enable wakeup from S3/S4
for the xHCI host.
Software can deal with this issue when the system is in S0. A work
around was put in to poll the port status registers for Compliance Mode.
The xHCI driver will continue to poll the registers while the host is
runtime suspended. Unfortunately, that means we can't allow the PCI
device to go into D3cold, because power will be removed from the host,
and the config space will read as all Fs.
Disable D3cold in the xHCI PCI runtime suspend function.

Commit 71c731a2 (usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP
Hardware) was a workaround for systems using the SN65LVPE502CP,
controller, but it introduced a bug in resume from hibernate.
The fix created a timer, comp_mode_recovery_timer, which is deleted from
a timer list when xhci_suspend() is called. However, the hibernate image,
including the timer list containing the comp_mode_recovery_timer, had
already been saved before the timer was deleted.
Upon resume from hibernate, the list containing the comp_mode_recovery_timer
is restored from the image saved to disk, and xhci_resume(), assuming that
the timer had been deleted by xhci_suspend(), makes a call to
compliance_mode_recoery_timer_init(), which creates a new instance of the
comp_mode_recovery_timer and attempts to place it into the same list in which
it is already active, thus corrupting the list during the list_add() call.
At this point, a call trace is emitted indicating the list corruption.
Soon afterward, the system locks up, the watchdog times out, and the
ensuing NMI crashes the system.
The problem did not occur when resuming from suspend. In suspend, the
image in RAM remains exactly as it was when xhci_suspend() deleted the
comp_mode_recovery_timer, so there is no problem when xhci_resume()
creates a new instance of this timer and places it in the still empty
list.
This patch avoids the problem by deleting the timer in xhci_resume()
when resuming from hibernate. Now xhci_resume() can safely make the
call to create a new instance of this timer, whether returning from
suspend or hibernate.
Thanks to Alan Stern for his help with understanding the problem.
[Sarah reworked this patch to cover the case where the xHCI restore
register operation fails, and (temp & STS_SRE) is true (and we re-init
the host, including re-init for the compliance mode), but hibernate is
false. The original patch would have caused list corruption in this
case.]

If for whatever reason we fall into fail path in xhci_mem_init()
before bw table gets initialized we may access the uninitialized lists
in xhci_mem_cleanup().
Check for bw table before traversing lists in cleanup routine.

It is possible that we fail on xhci_mem_init, just before doing
the INIT_LIST_HEAD, and calling xhci_mem_cleanup.
Problem is that, the list_for_each_entry_safe macro, assumes
list heads are initialized (not NULL), and dereferences their 'next'
pointer, causing a kernel panic if this is not yet initialized.
Let's protect from that by moving inits to the beginning.

usb: fixes for v3.10-rc4
Fix for a long standing bug where we would try to free
resources which we never allocated for DWC3's physical
endpoints 0 and 1.
DWC3 also learned that when calling glue layer's ->remove()
method, ordering of the teardown logic matters. This fixes
a bug where we would try to act on bogus PHY resources.
Lastly, MUSB learns about proper URB handling when the URB's
buffer sits in highmen. In order to fix the bug, use_sg flag
is moved down to the URB.

Since highmem PIO URB handling was introduced in:
8e8a551 usb: musb: host: Handle highmem in PIO mode
when a URB is being handled it may happen that the static use_sg flag
was set by a previous URB with buffer in highmem. This leads to error
in handling the present URB.
Fix this by making the use_sg flag URB specific.

we never allocate a TRB pool for physical endpoints
0 and 1 so trying to free it (a invalid TRB pool pointer)
will lead us in a warning while removing dwc3.ko module.
In order to fix the situation, all we have to do is skip
dwc3_free_trb_pool() for physical endpoints 0 and 1 just
as we while deleting endpoints from the endpoints list.

If the glue layer is removed first (core layer later),
it deletes the phy device first, then the core device.
But at core's removal, it still uses PHY's resources, it may
cause kernel's oops. It is much like the problem
Paul Zimmerman reported at:
http://marc.info/?l=linux-usb&m=136547502011472&w=2.
Besides, it is reasonable the PHY is deleted at last as
the controller is the PHY's user.
