In the past the transfer function was implied by the colorspace. However,
it is an independent entity in its own right. Add support for explicitly
choosing the transfer function.
This change will allow us to represent linear RGB (as is used by openGL), and
it will make it easier to work with decoded video material since most codecs
store the transfer function as a separate property as well.

mirror or redirect the packet by dynamic ifindex selection
from within the program to a target device either at ingress

* 'virtio-gpu-drm-next' of git://git.kraxel.org/linux:
Add MAINTAINERS entry for virtio-gpu.
Add virtio gpu driver.
drm_vblank_get: don't WARN_ON in case vblanks are not initialized
break kconfig dependency loop
This patch adds a kms driver for the virtio gpu. The xorg modesetting
driver can handle the device just fine, the framebuffer for fbcon is
there too.
Qemu patches for the host side are under review currently.
The pci version of the device comes in two variants: with and without
vga compatibility. The former has a extra memory bar for the vga
framebuffer, the later is a pure virtio device. The only concern for
this driver is that in the virtio-vga case we have to kick out the
firmware framebuffer.
Initial revision has only 2d support, 3d (virgl) support requires
some more work on the qemu side and will be added later.

This patch adds four new IOCTLs to amdkfd. These IOCTLs expose a H/W
debugger functionality to the userspace.
The IOCTLs are:
- AMDKFD_IOC_DBG_REGISTER:
The purpose of this IOCTL is to notify amdkfd that a process wants to use
GPU debugging facilities on itself only.
It is expected that this IOCTL would be called before any other H/W
debugger requests are sent to amdkfd and for each GPU where the H/W
debugging needs to be enabled. The use of this IOCTL ensures that only
one instance of a debugger is active in the system.
- AMDKFD_IOC_DBG_UNREGISTER:
This IOCTL detaches the debugger/debugged process from the H/W
Debug which was established by the AMDKFD_IOC_DBG_REGISTER IOCTL.
- AMDKFD_IOC_DBG_ADDRESS_WATCH:
This IOCTL allows to set different watchpoints with various conditions as
indicated by the IOCTL's arguments. The available number of watchpoints
is retrieved from topology. This operation is confined to the current
debugged process, which was registered through AMDKFD_IOC_DBG_REGISTER.
- AMDKFD_IOC_DBG_WAVE_CONTROL:
This IOCTL allows to control a wavefront as indicated by the IOCTL's
arguments. For example, you can halt/resume or kill either a
single wavefront or a set of wavefronts. This operation is confined to
the current debugged process, which was registered through
AMDKFD_IOC_DBG_REGISTER.
Because the arguments for the address watch IOCTL and wave control IOCTL
are dynamic, meaning that they could vary in size, the userspace passes a
pointer to a structure (in userspace) that contains the value of the
arguments. The kernel driver is responsible to parse this structure and
validate its contents.

The VNET_LE flag was introduced to fix accesses to virtio 1.0 headers
that are always little-endian. It can also be used to handle the special
case of a legacy little-endian device implemented by a big-endian host.
Let's add a flag and ioctls for big-endian devices as well. If both flags
are set, little-endian wins.
Since this is isn't a common usecase, the feature is controlled by a kernel
config option (not set by default).
Both macvtap and tun are covered by this patch since they share the same
API with userland.

This patch brings cross-endian support to vhost when used to implement
legacy virtio devices. Since it is a relatively rare situation, the
feature availability is controlled by a kernel config option (not set
by default).
The vq->is_le boolean field is added to cache the endianness to be
used for ring accesses. It defaults to native endian, as expected
by legacy virtio devices. When the ring gets active, we force little
endian if the device is modern. When the ring is deactivated, we
revert to the native endian default.
If cross-endian was compiled in, a vq->user_be boolean field is added
so that userspace may request a specific endianness. This field is
used to override the default when activating the ring of a legacy
device. It has no effect on modern devices.

Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next, they are:
1) default CONFIG_NETFILTER_INGRESS to y for easier compile-testing of all
options.
2) Allow to bind a table to net_device. This introduces the internal
NFT_AF_NEEDS_DEV flag to perform a mandatory check for this binding.
This is required by the next patch.
3) Add the 'netdev' table family, this new table allows you to create ingress
filter basechains. This provides access to the existing nf_tables features
from ingress.
4) Kill unused argument from compat_find_calc_{match,target} in ip_tables

Intel Wired LAN Driver Updates 2015-05-28
This series contains updates to ethtool, ixgbe, i40e and i40evf.
John adds helper routines for ethtool to pass VF to rx_flow_spec. Since
the ring_cookie is 64 bits wide which is much larger than what could be
used for actual queue index values, provide helper routines to pack a VF
index into the cookie. Then John provides a ixgbe patch to allow flow
director to use the entire queue space.
Neerav provides a i40e patch to collect XOFF Rx stats, where it was not
being collected before.
Anjali provides ATR support for tunneled packets, as well as stats to
count tunnel ATR hits. Cleaned up PF struct members which are
unnecessary, since we can use the stat index macro directly. Cleaned
up flow director ATR/SB messages to a higher debug level since they
are not useful unless silicon validation is happening.
Greg provides a patch to disable offline diagnostics if VFs are enabled
since ethtool offline diagnostic tests are not designed (out of scope)
to disable VF functions for testing and re-enable afterward. Also cleans
up TODO comment that is no longer needed.
Vasu provides a fix an FCoE EOF case where i40e_fcoe_ctxt_eof() maybe
called before i40e_fcoe_eof_is_supported() is called.
Jesse adds skb->xmit_more support for i40evf. Then provides a performance
enhancement for i40evf by inlining some functions which provides a 15%
gain in small packet performance. Also cleans up the use of time_stamp
since it is no longer used to determine if there is a tx_hang and was
a part of a previous tx_hang design which is no longer used.

classic BPF already exposes skb->dev->ifindex via SKF_AD_IFINDEX extension.
Allow eBPF program to access it as well. Note that classic aborts execution
of the program if 'skb->dev == NULL' (which is inconvenient for program
writers), whereas eBPF returns zero in such case.
Also expose the 'skb_iif' field, since programs triggered by redirected
packet need to known the original interface index.

* ACPI0008 ambient light sensor driver. This one has been around a long time to

* Berlin SOC ADC support.
* BMC150 magnetometer. The accelerometer in the same package has been supported

* Sensortek STK8312 accelerometer.
* Sensortek STK8BA50 accelerometer.
* ti-adc128s052 gains support form the adc122s021 2 channel ADC.
Driver cleanups and functionality.
* Allow various drivers to compile with !GPIOLIB if COMPILE_TEST enabled.
* bmc150 - decouple trigger from buffer to allow other triggers to be used.
* bmg160 - decouple trigger from buffer to allow other triggers to be used.
Fix a trivial unused field.
* Constify a load of platform_device_id structures.
* inv_mpu6050 - device tree bindings.
* hid-sensors - fix a memory leak during probe if certain errors occur.
* ltr501 - illuminance channel derived (in an non obvious fashion) from the
intensity channels.
* ltr501 - fix a boundary check on the proximity threshold.
* mlx90614 - drop a pointless return.
* mma8452 - Debugfs register access and fix a bug that had no effect (by
coincidence)
* ti_am335x_adc - add device tree bindings for sample-delay, open-delay and
averaging. The ideal settings for these tend to be board design specific.
