39076b047b net: mvmdio: Check for a valid interrupt instead of an error
The following commit:

commit 9ec36cafe43bf835f8f29273597a5b0cbc8267ef
Author: Rob Herring <robh@kernel.org>
Date:   Wed Apr 23 17:57:41 2014 -0500

    of/irq: do irq resolution in platform_get_irq

changed platform_get_irq() which now returns EINVAL and EPROBE_DEFER,
in addition to ENXIO. If there's no interrupt for mvmdio, platform_get_irq()
returns EINVAL, but we currently check only for ENXIO.

Fix this by looking for a positive integer, which is the proper way of
validating a virtual interrupt number.

While at it, add a proper handling for the deferral probe case.

The "default" pinctrl state is set by Drivers core now before
calling the driver's probe.
Hence, it's safe to drop pinctrl_pm_select_default_state() call
from Davinci mdio driver probe.

ca8b6e04bc net: via-rhine: Drop revision property, use quirks instead
This adds two new flags to quirks and thus removes the need to carry
revision in rhine_private. As a result, the init logic is simplified
a bit.

This also fixes a compiler warning in OF code on 64bit due to pointer
casting:

        drivers/net/ethernet/via/via-rhine.c: In function ‘rhine_init_one_platform’:
        drivers/net/ethernet/via/via-rhine.c:1132:13: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
          revision = (u32)match->data;
                     ^

That code was added in commit 2d283862dc62daead9db0dc89cd0d0351e91f765
("net: via-rhine: add OF bus binding").

Tested in platform configuration on a VIA WM8950 APC Rock board.

c0940e95f7 Revert "hwmon: (coretemp) Refine TjMax detection"
This reverts commit 9fb6c9c73b11bef65ba80a362547fd116c1e1c9d.

Tjmax on some Intel CPUs is below 85 degrees C. One known example is
L5630 with Tjmax of 71 degrees C. There are other Xeon processors with
Tjmax of 70 or 80 degrees C. Also, the Intel IA32 System Programming
document states that the temperature target is in bits 23:16 of MSR 0x1a2
(MSR_TEMPERATURE_TARGET), which is 8 bits, not 7.

So even if turbostat uses similar checks to validate Tjmax, there is no
evidence that the checks are actually required. On the contrary, the
checks are known to cause problems and therefore need to be removed.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=75071.

4985c32ee4 ACPI / processor: Fix failure of loading acpi-cpufreq driver
According commit d640113fe (ACPI: processor: fix acpi_get_cpuid for UP
processor),  BIOS may not provide _MAT or MADT tables and acpi_get_apicid()
always returns -1. For these cases, original code will pass apic_id with
vaule of -1 to acpi_map_cpuid() and it will check the acpi_id. If acpi_id
is equal to zero, ignores apic_id and return zero for CPU0.

Commit b981513 (ACPI / scan: bail out early if failed to parse APIC
ID for CPU) changed the behavior. Return ENODEV when find apic_id is
less than zero after calling acpi_get_apicid(). This causes acpi-cpufreq
driver fails to be loaded on some machines. This patch is to fix it.

Jonathan writes:

Second set of fixes for IIO in the 3.15 cycle.

* ad2s1200 - Fix some missing parenthesis in a for statement that could have
  led to an error being missed when getting gpios.
* Fix a null derefference issue in the mpu6050 when platform data is not
  provided (or is provided via the device tree for example).
* exynos_adc bug on remove due to child devices having been added to the
  parent of the IIO device rather than the IIO device itself.  This caused an
  issue with the IIO device removing itself in it's remove function.
* Make all ADC drivers buildable as modules to avoid dependency issues if
  the IIO core is itself built as a module.  The exynos adc bug became
  apparently whilst this fix was being tested.

a8d2239630 PNP / ACPI: Do not return errors if _DIS or _SRS are not present
The ACPI PNP subsystem returns errors from pnpacpi_set_resources()
and pnpacpi_disable_resources() if the _SRS or _DIS methods are not
present, respectively, but it should not do that, because those
methods are optional.  For this reason, modify pnpacpi_set_resources()
and pnpacpi_disable_resources(), respectively, to ignore missing _SRS
or _DIS.

This problem has been uncovered by commit 202317a573b2 (ACPI / scan:
Add acpi_device objects for all device nodes in the namespace) and
manifested itself by causing serial port suspend to fail on some
systems.

6ce29b0e2a gianfar: Avoid unnecessary reg accesses in adjust_link()
For phy devices that don't issue interrupts upon link
state changes, phylib polls the link state resulting in
repeated calls to adjust_link(), even if the link state
didn't change.  As a result, some mac registers are
repeatedly read and written with the same values, which
is not ok.

To fix this, adjust_link() has been refactored to check
first whether the link state has changed and to take action
only if needed, updating mac registers and local state
variables.  The 'new_state' local flag, set if one of the
link params changed (link, speed or duplex), has been
rendered useless and removed by this refactoring.

f114890cdf Revert "macvlan : fix checksums error when we are in bridge mode"
This reverts commit 12a2856b604476c27d85a5f9a57ae1661fc46019.
The commit above doesn't appear to be necessary any more as the
checksums appear to be correctly computed/validated.

Additionally the above commit breaks kvm configurations where
one VM is using a device that support checksum offload (virtio) and
the other VM does not.
In this case, packets leaving virtio device will have CHECKSUM_PARTIAL
set.  The packets is forwarded to a macvtap that has offload features
turned off.  Since we use CHECKSUM_UNNECESSARY, the host does does not
update the checksum and thus a bad checksum is passed up to
the guest.

cbdb04279c mactap: Fix checksum errors for non-gso packets in bridge mode
The following is a problematic configuration:

 VM1: virtio-net device connected to macvtap0@eth0
 VM2: e1000 device connect to macvtap1@eth0

The problem is is that virtio-net supports checksum offloading
and thus sends the packets to the host with CHECKSUM_PARTIAL set.
On the other hand, e1000 does not support any acceleration.

For small TCP packets (and this includes the 3-way handshake),
e1000 ends up receiving packets that only have a partial checksum
set.  This causes TCP to fail checksum validation and to drop
packets.  As a result tcp connections can not be established.

Commit 3e4f8b787370978733ca6cae452720a4f0c296b8
	macvtap: Perform GSO on forwarding path.
fixes this issue for large packets wthat will end up undergoing GSO.
This commit adds a check for the non-GSO case and attempts to
compute the checksum for partially checksummed packets in the
non-GSO case.

rename the function to sgdma_setup_descrip().

c25aaf814a hyperv: Enable sendbuf mechanism on the send path
We send packets using a copy-free mechanism (this is the Guest to Host transport
via VMBUS). While this is obviously optimal for large packets,
it may not be optimal for small packets. Hyper-V host supports
a second mechanism for sending packets that is "copy based". We implement that
mechanism in this patch.

In this version of the patch I have addressed a comment from David Miller.

With this patch (and all of the other offload and VRSS patches), we are now able
to almost saturate a 10G interface between Linux VMs on Hyper-V
on different hosts - close to  9 Gbps as measured via iperf.

6ebbc1a638 virtio-net: Set needed_headroom for virtio-net when VIRTIO_F_ANY_LAYOUT is true
This is a small supplement for commit e7428e95a06fb516fac1308bd0e176e27c0b9287
("virtio-net: put virtio-net header inline with data"). TCP packages have
enough room to put virtio-net header in, but UDP packages do not. By
setting dev->needed_headroom for virtio-net device, UDP packages could have
enough room.

For UDP packages, sk_buff is alloced in fun __ip_append_data. The size is
"alloclen + hh_len + 15", and "hh_len = LL_RESERVED_SPACE(rt-dst.dev);".
The Macro is defined as follows:
#define LL_RESERVED_SPACE(dev) \
     ((((dev)->hard_header_len+(dev)->needed_headroom)\
     &~(HH_DATA_MOD - 1)) + HH_DATA_MOD)
By default, for UDP packages, after skb is allocated, only 16 bytes
reserved. And 2 bytes remained after mac header is set. That is not enough
to put virtio-net header in. If we set dev->needed_headroom to 12 or 10
(according to mergeable_rx_bufs is on or off ), more room can be reserved.
Then there is enough room for UDP packages to put the header in.

5f9186990e rtlwifi: rtl8192se: Fix regression due to commit 1bf4bbb
Beginning with kernel 3.13, this driver fails on some systems. The problem
was bisected to:

Commit 1bf4bbb4024dcdab5e57634dd8ae1072d42a53ac
Author: Felix Fietkau <nbd@openwrt.org>
Title: mac80211: send control port protocol frames to the VO queue

There is noting wrong with the above commit. The regression occurs because
V0 queue on RTL8192SE cards uses priority 6, not the usual 7. The fix is to
modify the rtl8192se routine that sets the correct transmit queue.
