Here are 3 small USB fixes for 3.11-rc5.
One is a fix that the ChromeOS developers ran into on some Intel
hardware, one is a build fix, and the last is a MAINTAINERS update to
help people figure out where to send USB network driver patches.
All of these have been in linux-next for a while.

- ACPI-based memory hotplug stopped working after a recent change,
because it's not possible to associate sufficiently many "physical"
devices with one ACPI device object due to an artificial limit.
Fix from Rafael J Wysocki removes that limit and makes memory
hotplug work again.
- A change made in 3.9 uncovered a bug in the ACPI processor driver
preventing NUMA nodes from being put offline due to an ordering
issue. Fix from Yasuaki Ishimatsu changes the ordering to make
things work again.
- One of the recent ACPI video commits (that hasn't been reverted
so far) uncovered a bug in the code handling quirky BIOSes that
caused some Asus machines to boot with backlight completely off
which made it quite difficult to use them afterward. Fix from
Felipe Contreras improves the quirk to cover this particular
case correctly.
- A cpufreq user space interface change made in 3.10 inadvertently
renamed the ignore_nice_load sysfs attribute to ignore_nice which
resulted in some confusion. Fix from Viresh Kumar changes the name
back to ignore_nice_load.
- An initialization ordering change made in 3.9 broke cpufreq on
loongson2 boards. Fix from Aaro Koskinen restores the correct
initialization ordering there.
- Fix breakage resulting from a mistake made in 3.9 and causing the
detection of some graphics adapters (that were detected correctly
before) to fail. There are two objects representing the same PCIe
port in the affected systems' ACPI tables and both appear as
"enabled" and we are expected to guess which one to use. We used
to choose the right one before by pure luck, but when we tried to
address another similar corner case, the luck went away. This time
we try to make our guessing a bit more educated which is reported
to work on those systems.
- The /proc/acpi/wakeup interface code is missing some locking
which may lead to breakage if that file is written or read during
hotplug of wakeup devices. That should be rare but still possible,
so it's better to start using the appropriate locking there.

Author: stephen hemminger <stephen@networkplumber.org>
Date: Sat Jul 13 10:18:18 2013 -0700
vxlan: add necessary locking on device removal
The problem is that vxlan_dellink(), which is called with RTNL lock
held, tries to flush the workqueue synchronously, but apparently
igmp_join and igmp_leave work need to hold RTNL lock too, therefore we
have a soft lockup!
As suggested by Stephen, probably the flush_workqueue can just be
removed and let the normal refcounting work. The workqueue has a
reference to device and socket, therefore the cleanups should work
correctly.

vxlan: fix igmp races
Before this commit, the old code was:
if (vxlan_group_used(vn, vxlan->default_dst.remote_ip))
ip_mc_join_group(sk, &mreq);
else
ip_mc_leave_group(sk, &mreq);
therefore we shoud check vxlan_group_used(), not its opposite,
for igmp_join.

This reverts commit 407a2c2a4d.
Explanation provided by Benjamin Tissoires:
Commit "HID: hid-logitech-dj, querying_devices was never set" activate
a flag which guarantees that we do not ask the receiver for too many
enumeration. When the flag is set, each following enumeration call is
discarded (the usb request is not forwarded to the receiver). The flag
is then released when the driver receive a pairing information event,
which normally follows the enumeration request.
However, the USB3 bug makes the driver think the enumeration request
has been forwarded to the receiver. However, it is actually not the
case because the USB stack returns -EPIPE. So, when a new unknown
device appears, the workaround consisting in asking for a new
enumeration is not working anymore: this new enumeration is discarded
because of the flag, which is never reset.
A solution could be to trigger a timeout before releasing it, but for
now, let's just revert the patch.

In adt7470_write_word_data(), which writes two bytes using
i2c_smbus_write_byte_data(), the return codes are incorrectly AND-ed
together when they should be OR-ed together.
The return code of i2c_smbus_write_byte_data() is zero for success.
The upshot is only the first byte was ever written to the hardware.
The 2nd byte was never written out.
I noticed that trying to set the fan speed limits was not working
correctly on my system. Setting the fan speed limits is the only
code that uses adt7470_write_word_data(). After making the change
the limit settings work and the alarms work also.

In theory, under a given ACPI namespace node there should be only
one child device object with _ADR whose value matches a given bus
address exactly. In practice, however, there are systems in which
multiple child device objects under a given parent have _ADR matching
exactly the same address. In those cases we use _STA to determine
which of the multiple matching devices is enabled, since some systems
are known to indicate which ACPI device object to associate with the
given physical (usually PCI) device this way.
Unfortunately, as it turns out, there are systems in which many
device objects under the same parent have _ADR matching exactly the
same bus address and none of them has _STA, in which case they all
should be regarded as enabled according to the spec. Still, if
those device objects are supposed to represent bridges (e.g. this
is the case for device objects corresponding to PCIe ports), we can
try harder and skip the ones that have no child device objects in the
ACPI namespace. With luck, we can avoid using device objects that we
are not expected to use this way.
Although this only works for bridges whose children also have ACPI
namespace representation, it is sufficient to address graphics
adapter detection issues on some systems, so rework the code finding
a matching device ACPI handle for a given bus address to implement
this idea.
Introduce a new function, acpi_find_child(), taking three arguments:
the ACPI handle of the device's parent, a bus address suitable for
the device's bus type and a bool indicating if the device is a
bridge and make it work as outlined above. Reimplement the function
currently used for this purpose, acpi_get_child(), as a call to
acpi_find_child() with the last argument set to 'false' and make
the PCI subsystem use acpi_find_child() with the bridge information
passed as the last argument to it. [Lan Tianyu notices that it is
not sufficient to use pci_is_bridge() for that, because the device's
subordinate pointer hasn't been set yet at this point, so use
hdr_type instead.]
This change fixes a regression introduced inadvertently by commit
33f767d (ACPI: Rework acpi_get_child() to be more efficient) which
overlooked the fact that for acpi_walk_namespace() "post-order" means
"after all children have been visited" rather than "on the way back",
so for device objects without children and for namespace walks of
depth 1, as in the acpi_get_child() case, the "post-order" callbacks
ordering is actually the same as the ordering of "pre-order" ones.
Since that commit changed the namespace walk in acpi_get_child() to
terminate after finding the first matching object instead of going
through all of them and returning the last one, it effectively
changed the result returned by that function in some rare cases and
that led to problems (the switch from a "pre-order" to a "post-order"
callback was supposed to prevent that from happening, but it was
ineffective).
As it turns out, the systems where the change made by commit
33f767d actually matters are those where there are multiple ACPI
device objects representing the same PCIe port (which effectively
is a bridge). Moreover, only one of them, and the one we are
expected to use, has child device objects in the ACPI namespace,
so the regression can be addressed as described above.

try_offline_node() checks that all CPUs associated with the given
node have been removed by using cpu_present_bits. If all cpus
related to that node have been removed, try_offline_node() clears
the node information.
However, try_offline_node() called from acpi_processor_remove() never
clears the node information. For disabling cpu_present_bits,
acpi_unmap_lsapic() needs be called. Yet, acpi_unmap_lsapic() is
called after try_offline_node() has run. So when try_offline_node()
runs, the CPU's cpu_present_bits is always set.
Fix the issue by moving try_offline_node() after acpi_unmap_lsapic().
The problem fixed here was uncovered by commit cecdb19 "ACPI / scan:

The SDVO code tries to compare the encoder's and crtc's idea of the
pixel_multiplier. Normally they have to match, but when transitioning
to DPMS off, we turn off the pipe before reading out the pipe_config,
so the pixel_multiplier in the pipe_config will be 0, whereas the
encoder will still have its pixel_multiplier set to whatever value we
were using when the display was active. This leads to a warning
from intel_modeset_check_state().

Apparently Bspec is wrong in this case here even for gm45. Note that
Bspec is horribly misguided on i965g/gm, so we don't have any other

With this changes all the bits in PORT_HOTPLUG_STAT for the digital
ports are ordered the same way. This seems to agree with what register
dumps from the hpd storm handling code shows, where the LIVE bit and
the short/long pulse STATUS bits light up at the same time with this
enumeration (but no with the one from Bspec).
Also tested on my gm45 which has two DP+ ports, and everything seems
to still work as expected.

The physical_node_id_bitmap in struct acpi_device is only used for
looking up the first currently unused dependent phyiscal node ID
by acpi_bind_one(). It is not really necessary, however, because
acpi_bind_one() walks the entire physical_node_list of the given
device object for sanity checking anyway and if that list is always
sorted by node_id, it is straightforward to find the first gap
between the currently used node IDs and use that number as the ID
of the new list node.
This also removes the artificial limit of the maximum number of
dependent physical devices per ACPI device object, which now depends
only on the capacity of unsigend int. As a result, it fixes a
regression introduced by commit e2ff394 (ACPI / memhotplug: Bind
removable memory blocks to ACPI device nodes) that caused
acpi_memory_enable_device() to fail when the number of 128 MB blocks
within one removable memory module was greater than 32.

The list of physical devices corresponding to an ACPI device
object is walked by acpi_system_wakeup_device_seq_show() and
physical_device_enable_wakeup() without taking that object's
physical_node_lock mutex. Since each of those functions may be
run at any time as a result of a user space action, the lack of
appropriate locking in them may lead to a kernel crash if that
happens during device hot-add or hot-remove involving the device
object in question.
Fix the issue by modifying acpi_system_wakeup_device_seq_show() and

Second round of IIO fixes for the 3.11 cycle.
1) Fix a long term race in the IIO trigger handling.
This only effects cases where a single trigger is in use
by multiple devices.
2) ti_am335x fix an issue with incorrect data due to reading before
the sequencer is finished.
Hi Greg,
Here's two small fixes for 3.11. The first patch fixes a 5 second hang in
khubd after a USB device disconnect on some xHCI hosts. The second fixes a
build warning.

If the _BCL package ordering is descending, the first level
(br->levels[2]) is likely to be 0, and if the number of levels
matches the number of steps, we might confuse a returned level to
mean the index.
For example:
current_level = max_level = 100
test_level = 0
returned level = 100
In this case 100 means the level, not the index, and _BCM failed.
Still, if the _BCL package ordering is descending, the index of
level 0 is also 100, so we assume _BQC is indexed, when it's not.
This causes all _BQC calls to return bogus values causing weird
behavior from the user's perspective. For example:
xbacklight -set 10; xbacklight -set 20;
would flash to 90% and then slowly down to the desired level (20).
The solution is simple; test anything other than the first level
(e.g. 1).

Problem: When Hardware IOMMU is on, megaraid_sas driver initialization fails
in kdump kernel with LSI MegaRAID controller(device id-0x73).
Actually this issue needs fix in firmware, but for firmware running in field,
this driver fix is proposed to resolve the issue. At firmware initialization
time, if firmware does not come to ready state, driver will reset the adapter
and retry for firmware transition to ready state unconditionally(not only
executed for kdump kernel).

- Revert two cpuidle commits added during the 3.8 development cycle that
turn out to have introduced a significant performance regression as
requested by Jeremy Eder.
- The recent patches that made the freezer less heavy-weight introduced
a regression causing user-space-driven hibernation using the ioctl()
interface to block indefinitely when the hibernate process executes
try_to_freeze(). Fix from Colin Cross addresses this by adding a
process flag to mark the hibernate/suspend process to inform the
freezer that that process should be ignored.
- One of the recent cpufreq reverts uncovered a problem in the core
causing the cpufreq driver module refcount to become negative after
a system suspend-resume cycle. Fix from Rafael J Wysocki.
- The evaluation of the ACPI battery _BIX method has never worked
correctly, because the commit that added support for it forgot to
take the "Revision" field in the return package into account. As
a result, the reading of battery info doesn't work at all on some
systems, which is addressed by a fix from Lan Tianyu.

Using rfkill switch can make firmware unstable, what cause various
Microcode errors and kernel warnings. Reseting firmware just after
rfkill off (radio on) helped with that.

If device was put into a sleep and system was restarted or module
reloaded, we have to wake device up before sending other commands.
Otherwise it will fail to start with Microcode error.

For a combination of 18bit LCD data bus width and a color
mode of 32bpp, the driver was setting the color mapping to
rgb666, which is wrong, as the color in memory realy has an
rgb888 layout.
This patch also removes the setting of flag CTRL_DF24 that
makes the driver dimiss the upper 2 bits when handling 32/24bpp
colors in a diplay with 18bit data bus width. This flag made
true color images display wrong in such configurations.
Finally, the color mapping rgb666 has also been removed as nobody
is using it and high level applications like Qt5 cannot work
with it either.

connector-analog-tv.c uses omap_dss_pal_timings, defined in omapdss's
venc.c, for default timings. omap_dss_pal_timings only exists when VENC
is enabled in the kernel config, so disabling VENC breaks
omap_dss_pal_timings connector-analog-tv compilation.
Instead of adding dependency to VENC, add internal default timings to
the connector driver, because the connector driver should not depend on
VENC, and it can be used with any other analog TV encoder.

macvlan passthrough mode is special: it's not possible to switch to or
from it through a netlink command.
But if you try, the command will succeed, which is
confusing.
