git://anongit.freedesktop.org/drm/drm-intel into drm-fixes
This contains a regression fix for video playbacks on gen 2 hardware,
a IPS timeout error suppression on Broadwell and GVT bucked with
"Most critical one is to fix KVM's mm reference when we access guest memory,
issue was raised by Linus [1], and another one with virtual opregion fix."

Fields ->dev and ->next of struct ipddp_route may be copied to
userspace on the SIOCFINDIPDDPRT ioctl. This is only accessible
to CAP_NET_ADMIN though. Let's manually copy the relevant fields
instead of using memcpy().

When netvsc device is removed it can call reschedule in RCU context.
This happens because canceling the subchannel setup work could (in theory)
cause a reschedule when manipulating the timer.
To reproduce, run with lockdep enabled kernel and unbind
a network device from hv_netvsc (via sysfs).

This patch implements XDP batching for vhost_net. The idea is first to
try to do userspace copy and build XDP buff directly in vhost. Instead
of submitting the packet immediately, vhost_net will batch them in an
array and submit every 64 (VHOST_NET_BATCH) packets to the under layer
sockets through msg_control of sendmsg().
When XDP is enabled on the TUN/TAP, TUN/TAP can process XDP inside a
loop without caring GUP thus it can do batch map flushing. When XDP is
not enabled or not supported, the underlayer socket need to build skb
and pass it to network core. The batched packet submission allows us
to do batching like netif_receive_skb_list() in the future.
This saves lots of indirect calls for better cache utilization. For
the case that we can't so batching e.g when sndbuf is limited or
packet size is too large, we will go for usual one packet per
sendmsg() way.
Doing testpmd on various setups gives us:
Test /+pps%
XDP_DROP on TAP /+44.8%
XDP_REDIRECT on TAP /+29%
macvtap (skb) /+26%
Netperf tests shows obvious improvements for small packet transmission:

the caller to pass an array of XDP buffs to tuntap through ptr field
of the tun_msg_control. Tap will build skb through those XDP buffers.
This will avoid lots of indirect calls thus improves the icache
utilization and allows to do XDP batched flushing when doing XDP

This patch introduces to a new tun/tap specific msg_control:
#define TUN_MSG_UBUF 1
#define TUN_MSG_PTR 2
struct tun_msg_ctl {
int type;
void *ptr;
};
This allows us to pass different kinds of msg_control through
sendmsg(). The first supported type is ubuf (TUN_MSG_UBUF) which will
be used by the existed vhost_net zerocopy code. The second is XDP
buff, which allows vhost_net to pass XDP buff to TUN. This could be
used to implement accepting an array of XDP buffs from vhost_net in
the following patches.

The recent change of vga_switcheroo allowed the runtime PM for
HD-audio on AMD GPUs, but this also resulted in a regression. When
the HD-audio controller driver gets runtime-suspended, HD-audio link
is turned off, and the hotplug notification is ignored. This leads to
the inconsistent audio state (the connection isn't notified and ELD is
ignored).
The best fix would be to implement the proper ELD notification via the
audio component, but it's still not ready. As a quick workaround,
this patch adds the check of runtime_idle and allows the runtime
suspend only when the vga_switcheroo is bound with discrete GPU.
That is, a system with a single GPU and APU would be again without
runtime PM to keep the HD-audio link for the hotplug notification and
ELD read out.
Also, the codec->auto_runtime_pm flag is set only for the discrete GPU
at the time GPU gets bound via vga_switcheroo (i.e. only dGPU is
forcibly runtime-PM enabled), so that APU can still get the ELD
notification.
For identifying which GPU is bound, a new vga_switcheroo client
callback, gpu_bound, is implemented. The vga_switcheroo simply calls
this when GPU is bound, and tells whether it's dGPU or APU.

Commit 57f230ab04d291 ("xen/netfront: raise max number of slots in
xennet_get_responses()") raised the max number of allowed slots by one.
This seems to be problematic in some configurations with netback using
a larger MAX_SKB_FRAGS value (e.g. old Linux kernel with MAX_SKB_FRAGS
defined as 18 instead of nowadays 17).
Instead of BUG_ON() in this case just fall back to retransmission.

This adds the DSA driver for the GSWIP Switch found in the VRX200 SoC.
This switch is integrated in the DSL SoC, this SoC uses a GSWIP version
2.1, there are other SoCs using different versions of this IP block, but
this driver was only tested with the version found in the VRX200.
Currently only the basic features are implemented which will forward all
packages to the CPU and let the CPU do the forwarding. The hardware also
support Layer 2 offloading which is not yet implemented in this driver.
The GPHY FW loaded is now done by this driver and not any more by the
separate driver in drivers/soc/lantiq/gphy.c, I will remove this driver
is a separate patch. to make use of the GPHY this switch driver is
needed anyway. Other SoCs have more embedded GPHYs so this driver should
support a variable number of GPHYs. After the firmware was loaded the
GPHY can be probed on the MDIO bus and it behaves like an external GPHY,
without the firmware it can not be probed on the MDIO bus.
The clock names in the sysctrl.c file have to be changed because the
clocks are now used by a different driver. This should be cleaned up and
a real common clock driver should provide the clocks instead.

This drives the PMAC between the GSWIP Switch and the CPU in the VRX200
SoC. This is currently only the very basic version of the Ethernet
driver.
When the DMA channel is activated we receive some packets which were
send to the SoC while it was still in U-Boot, these packets have the
wrong header. Resetting the IP cores did not work so we read out the
extra packets at the beginning and discard them.
This also adapts the clock code in sysctrl.c to use the default name of
the device node so that the driver gets the correct clock. sysctrl.c
should be replaced with a proper common clock driver later.

Currently, the CCP driver assumes that the SEV command issued to the PSP
will always return (i.e. it will never hang). But recently, firmware bugs
have shown that a command can hang. Since of the SEV commands are used
in probe routines, this can cause boot hangs and/or loss of virtualization
capabilities.
To protect against firmware bugs, add a timeout in the SEV command
execution flow. If a command does not complete within the specified
timeout then return -ETIMEOUT and stop the driver from executing any
further commands since the state of the SEV firmware is unknown.

Rather than have MAC drivers open code the test, add a helper in
phylib. This will help when we change the type of phydev->supported.

PHY drivers don't indicate they support pause. They expect MAC drivers
to enable its support if the MAC has the needed hardware. Thus MAC
drivers should not mask Pause support, but enable it.
Change a few ANDs to ORs.

The phy supported speed is being used to determine if the MAC should
be configured to 100 or 1G. The masking logic is broken. Instead, look
at 1G supported speeds to enable 1G MAC support.

Many Ethernet MAC drivers want to limit the PHY to only advertise a

of the helper function phy_set_max_speed().

The driver indicates it can do 10/100 full and half duplex, plus 1G
Full. The datasheet indicates 1G half is also supported. So make use
of the standard PHY_GBIT_FEATURES.
It could be, this was added because there is a MAC which does not
support 1G half. Bit this is the wrong place to enforce this.

The supported added for zones in null_blk seem to assume that only rq
based operation is possible. But this depends on the queue_mode setting,
if this is set to 0, then cmd->bio is what we need to be operating on.
Right now any attempt to load null_blk with queue_mode=0 will
insta-crash, since cmd->rq is NULL and null_handle_cmd() assumes it to
always be set.
Make the zoned code deal with bio's instead, or pass in the
appropriate sector/nr_sectors instead.
