There is need to instruct the HW offloaded path to push certain matched
packets to cpu/kernel for further analysis. So this patch introduces a
new TRAP control action to TC.
For kernel datapath, this action does not make much sense. So with the
same logic as in HW, new TRAP behaves similar to STOLEN. The skb is just
dropped in the datapath (and virtually ejected to an upper level, which
does not exist in case of kernel).

skl_check_plane_surface() already rotates the clipped plane source
coordinates to match the scanout direction because that's the way
the GTT mapping is set up. Thus we no longer need to rotate the
coordinates in the watermark code.
For cursors we use the non-clipped coordinates which are not rotated
appropriately, but that doesn't actually matter since cursors don't
even support 90/270 degree rotation.

Starting from commit b63a16f6cd ("drm/i915: Compute display surface
offset in the plane check hook for SKL+") we've already rotated the src
coordinates by 270 degrees by the time we check if a scaler is needed
or not, so we must not account for the rotation a second time.
Previously we did these steps in the opposite order and hence the
scaler check had to deal with rotation itself. The double rotation
handling causes us to enable a scaler pretty much every time 90/270
degree plane rotation is requested, leading to fuzzier fonts and whatnot.

Merge tag 'rxrpc-rewrite-20170606' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
David Howells says:
====================
rxrpc: Support service upgrade
Here's a set of patches that allow AF_RXRPC to support the AuriStor service
upgrade facility. This allows the server to change the service ID
requested to an upgraded service if the client requests it upon the
initiation of a connection.
This is used by the AuriStor AFS-compatible servers to implement IPv6
handling and improved facilities by providing improved volume location,
volume, protection, file and cache management services. Note that certain
parts of the AFS protocol carry hard-coded IPv4 addresses.
The reason AuriStor does it this way is that probing the improved service
ID first will not incur an ABORT or any other response on some servers if
the server is not listening on it - and so one have to employ a timeout.
This is implemented in the server by allowing an AF_RXRPC server to call
bind() twice on a socket to allow it to listen on two service IDs and then
call setsockopt() to instruct the server to upgrade one into the other if
the client requests it (by setting userStatus to 1 on the first DATA packet
on a connection). If the upgrade occurs, all further operations on that
connection are done with the new service ID. AF_RXRPC has to handle this
automatically as connections are not exposed to userspace.
Clients can request this facility by setting an RXRPC_UPGRADE_SERVICE
command in the sendmsg() control buffer and then observing the resultant
service ID in the msg_addr returned by recvmsg(). This should only be used
to probe the service. Clients should then use the returned service ID in
all subsequent communications with that server. Note that the kernel will
not retain this information should the connection expire from its cache.

The number of compressed segments has been available ever since
FBC2 was introduced in g4x, it just moved from the STATUS register
into STATUS2 on IVB.
For FBC1 if we really wanted the number of compressed segments we'd
have to trawl through the tags, but in this case since the code just
uses the number of compressed segments as an indicator whether
compression has occurred we can just check the state of the
COMPRESSING and COMPRESSED bits. IIRC the hardware will try to
periodically recompress all uncompressed lines even if they haven't
changed and the COMPRESSED bit will be cleared while the compressor
is running, so just checking the COMPRESSED bit might not give us
the right answer. Hence it seems better to check for both
COMPRESSED and COMPRESSING as that should tell us that the
compressor is at least trying to do something.
While at it move the IVB+ register define to the right place, unify
the naming convention of the compressed segment count masks, and
fix up the mask for g4x.

1GbE Intel Wired LAN Driver Updates 2017-06-06
This series contains updates and fixes to e1000e and igb.
Matwey V Kornilov fixes an issue where igb_get_phy_id_82575() relies on
the fact that page 0 is already selected, but this is not the case after
igb_read_phy_reg_gs40g()/igb_write_phy_reg_gs40g() were removed in a
previous commit. This leads to initialization failure and some devices
not working. To fix the issue, explicitly select page 0 before first
access to PHY registers.
Arnd Bergmann modifies the driver to avoid a "defined but not used"
warning by removing #ifdefs and using __maybe_unused annotation instead
for new power management functions.
Jake provides most of the changes in the series, all around PTP and
timestamp fixes/updates. Resolved several race conditions based on
the hardware can only handle one transmit timestamp at a time, so
fix the locking logic, as well as create a statistic for "skipped"
timestamps to help administrators identify issues.
Benjamin Poirier provides 2 changes, first to igb to remove the
second argument to igb_update_stats() since it always passes the
same two arguments. So instead of having to pass the second argument,
just update the function to the necessary information from the adapter
structure. Second modifies the e1000e_get_stats64() call to
dev_get_stats() to avoid ethtool garbage being reported.
Konstantin Khlebnikov modifies e1000e to use disable_hardirq(), instead
of disable_irq() for MSIx vectors in e1000_netpoll().

The scanline counter is bonkers on VLV/CHV DSI. The scanline counter
increment is not lined up with the start of vblank like it is on
every other platform and output type. This causes problems for
both the vblank timestamping and atomic update vblank evasion.
On my FFRD8 machine at least, the scanline counter increment
happens about 1/3 of a scanline ahead of the start of vblank (which
is where all register latching happens still). That means we can't
trust the scanline counter to tell us whether we're in vblank or not
while we're on that particular line. In order to keep vblank
timestamping in working condition when called from the vblank irq,
we'll leave scanline_offset at one, which means that the entire
line containing the start of vblank is considered to be inside
the vblank.
For the vblank evasion we'll need to consider that entire line
to be bad, since we can't tell whether the registers already
got latched or not. And we can't actually use the start of vblank
interrupt to get us past that line as the interrupt would fire
too soon, and then we'd up waiting for the next start of vblank
instead. One way around that would using the frame start
interrupt instead since that wouldn't fire until the next
scanline, but that would require some bigger changes in the
interrupt code. So for simplicity we'll just poll until we get
past the bad line.

This is triggered occasionally by running both win7 and win2016 in L2, in
addition, EPT is disabled on both L1 and L2. It can't be reproduced easily.
Commit 0b6ac343fc (KVM: nVMX: Correct handling of exception injection) mentioned
that "KVM wants to inject page-faults which it got to the guest. This function
assumes it is called with the exit reason in vmcs02 being a #PF exception".
Commit e011c663 (KVM: nVMX: Check all exceptions for intercept during delivery to
L2) allows to check all exceptions for intercept during delivery to L2. However,
there is no guarantee the exit reason is exception currently, when there is an
external interrupt occurred on host, maybe a time interrupt for host which should
not be injected to guest, and somewhere queues an exception, then the function
nested_vmx_check_exception() will be called and the vmexit emulation codes will
try to emulate the "Acknowledge interrupt on exit" behavior, the warning is
triggered.
Reusing the exit reason from the L2->L0 vmexit is wrong in this case,
the reason must always be EXCEPTION_NMI when injecting an exception into
L1 as a nested vmexit.

Use rvin_reset_format() in rvin_s_dv_timings() instead of just resetting
a few fields. This fixes an issue where the field format was not
properly set after S_DV_TIMINGS.

These two were forgotten when refactoring the format reset code. If
they are not also reset at the same time as width and height the format
returned from G_FMT will not match reality.

native_safe_halt enables interrupts, and you just shouldn't
call rcu_irq_enter() with interrupts enabled. Reorder the
call with the following local_irq_disable() to respect the
invariant.

Remove the SNB PCH refclock init call from the runtime resume handler.
I don't think it was actually needed even when we had SNB runtime PM,
and if definitely isn't needed ever since SNB runtime PM was nuked in
commit d4c5636e74 ("drm/i915: Remove runtime PM for SNB").

The fwnode_handle is a more generic way than OF device_node to describe
firmware nodes. Instead of the OF API, use more generic fwnode API to
obtain the same information.
As the V4L2 fwnode support will be required by a small minority of e.g.
ACPI based systems (the same might actually go for OF), make this a module
instead of embedding it in the videodev module.
The origins of the V4L2 fwnode framework is in the V4L2 OF framework.
