There's no point in enabling PSR when the panel doesn't support it.
This also avoids a problem when PSR gets enabled when a CRTC is being
disabled, because sometimes in that situation the DSP_HOLD_VALID_INTR
interrupt on which we wait will never arrive. This was observed on
RK3288 with a panel without PSR (veyron-jaq Chromebook).
It's very easy to reproduce by running the kms_rmfb test in IGT a few
times.

It's not that obvious how a driver can all race the atomic commit with
handling the completion event. And there's unfortunately a pile of
drivers with rather bad event handling which misdirect people into the
wrong direction.
Try to remedy this by documenting everything better.

It's perfectly legal for the sink to support 12bpc only for
some lower resolution modes, while the higher resolution modes
can only be used with 8bpc. So let's take the sink's max TMDS clock
into account before we go and decide that a particular mode can
be used with 12bpc.

drm_edid_to_eld() is just mean to cook up the ELD for the audio driver,
so having it parse non-audio related stuff seems just wrong, and
potentially could lead to that information not being even filled out
if the function doesn't even get called. Let's move that stuff to the
place where we parse the color formats and whatnot from the CEA ext
block.

Currently we use a linear walk to lookup a handle and return a dma-buf,
and vice versa. A long overdue TODO task is to convert that to a
hashtable. Since the initial implementation of dma-buf/prime, we now
have resizeable hashtables we can use (and now a future task is to RCU
enable the lookup!). However, this patch opts to use an rbtree instead
to provide O(lgN) lookups (and insertion, deletion). rbtrees were chosen
over using the RCU backed resizable hashtable to firstly avoid the
reallocations (rbtrees can be embedded entirely within the parent
struct) and to favour simpler code with predictable worst case
behaviour. In simple testing, the difference between using the constant
lookup and insertion of the rhashtable and the rbtree was less than 10%
of the wall time (igt/benchmarks/prime_lookup) - both are dramatic
improvements over the existing linear lists.
v2: Favour rbtree over rhashtable

If the capi link is going down while the PSL owns a dirty cache line,
any access from the host for that data could lead to an Uncorrectable
Error.
So when resetting the capi adapter through sysfs, make sure the PSL
cache is flushed. It won't help if there are any active Process
Elements on the card, as the cache would likely get new dirty cache
lines immediately, but if resetting an idle adapter, it should avoid
any bad surprises from data left over from terminated Process Elements.

Edge-rate:
As system and networking speeds increase, a signal's output transition,
also know as the edge rate or slew rate (V/ns), takes on greater importance
because high-speed signals come with a price. That price is an assortment of
interference problems like ringing on the line, signal overshoot and
undershoot, extended signal settling times, crosstalk noise, transmission
line reflections, false signal detection by the receiving device and
electromagnetic interference (EMI) -- all of which can negate the potential
gains designers are seeking when they try to increase system speeds through
the use of higher performance logic devices. The fact is, faster signaling
edge rates can cause a higher level of electrical noise or other type of
interference that can actually lead to slower line speeds and lower maximum
system frequencies. This parameter allow the board designers to change the
driving strange, and thereby change the EMI behavioral.
Edge-rate parameters (vddmac, edge-slowdown) get from Device Tree.
Tested on Beaglebone Black with VSC 8531 PHY.

Although rare, it's possible to hit PCI error early on device
probe, meaning possibly some structs are not entirely initialized,
and some might even be completely uninitialized, leading to NULL
pointer dereference.
The i40e driver currently presents a "bad" behavior if device hits
such early PCI error: firstly, the struct i40e_pf might not be
attached to pci_dev yet, leading to a NULL pointer dereference on
access to pf->state.
Even checking if the struct is NULL and avoiding the access in that
case isn't enough, since the driver cannot recover from PCI error
that early; in our experiments we saw multiple failures on kernel
log, like:
[549.664] i40e 0007:01:00.1: Initial pf_reset failed: -15
[549.664] i40e: probe of 0007:01:00.1 failed with error -15
[...]
[871.644] i40e 0007:01:00.1: The driver for the device stopped because the
device firmware failed to init. Try updating your NVM image.
[871.644] i40e: probe of 0007:01:00.1 failed with error -32
[...]
[872.516] i40e 0007:01:00.0: ARQ: Unknown event 0x0000 ignored
Between the first probe failure (error -15) and the second (error -32)
another PCI error happened due to the first bad probe. Also, driver
started to flood console with those ARQ event messages.
This patch will prevent these issues by allowing error recovery
mechanism to remove the failed device from the system instead of
trying to recover from early PCI errors during device probe.

40GbE Intel Wired LAN Driver Updates 2016-10-03
This series contains fixes to i40e only.
Stefan Assmann provides the changes in this series to resolve an issue
where when we run out of MSIx vectors, iWARP gets disabled automatically.
First adds a check for "no vectors left" during MSIx vector allocation
for VMDq, which will prevent more vectors being allocated than available.
Then fixed the MSIx vector redistribution when we reach the hardware limit
for vectors so that additional features like VMDq, iWARP, etc do not get
starved for vectors because the PF is hogging all the resources. Lastly,
fix the issue for flow director by moving the check for the reaching the
vector limit earlier in the code so that a decision can be made on
disabling flow director.

Before commit a325725633c2 ("drm: Lobotomize set_busid nonsense for !pci
drivers"), several DRM drivers for platform devices used to expose an
explicit "drm_driver.set_busid" callback, invariably backed by
drm_platform_set_busid().
Commit a325725633c2 removed drm_platform_set_busid(), along with the
referring .set_busid field initializations. This was justified because
interchangeable functionality had been implemented in drm_dev_alloc() /
drm_dev_init(), which DRM_IOCTL_SET_VERSION would rely on going forward.
However, commit a325725633c2 also removed drm_virtio_set_busid(), for
which the same consolidation was not appropriate: this .set_busid callback
had been implemented with drm_pci_set_busid(), and not
drm_platform_set_busid(). The error regressed Xorg/xserver on QEMU's
"virtio-vga" card; the drmGetBusid() function from libdrm would no longer
return stable PCI identifiers like "pci:0000:00:02.0", but rather unstable
platform ones like "virtio0".
Reinstate drm_virtio_set_busid() with judicious use of

drm: Extract drm_plane.[hc]
which meant on error paths drm_crtc_vblank_put could be called without
a get, leading to an underrun of the refcount.

Pull CPU hotplug updates from Thomas Gleixner:
"Yet another batch of cpu hotplug core updates and conversions:
- Provide core infrastructure for multi instance drivers so the
drivers do not have to keep custom lists.
- Convert custom lists to the new infrastructure. The block-mq custom
list conversion comes through the block tree and makes the diffstat
tip over to more lines removed than added.
- Handle unbalanced hotplug enable/disable calls more gracefully.
- Remove the obsolete CPU_STARTING/DYING notifier support.
- Convert another batch of notifier users.
The relayfs changes which conflicted with the conversion have been
shipped to me by Andrew.
The remaining lot is targeted for 4.10 so that we finally can remove
the rest of the notifiers"

Pull irq updates from Thomas Gleixner:
"The irq departement proudly presents:
- A rework of the core infrastructure to optimally spread interrupt
for multiqueue devices. The first version was a bit naive and
failed to take thread siblings and other details into account.
Developed in cooperation with Christoph and Keith.
- Proper delegation of softirqs to ksoftirqd, so if ksoftirqd is
active then no further softirq processsing on interrupt return
happens. Otherwise we try to delegate and still run another batch
of network packets in the irq return path, which then tries to
delegate to ksoftirqd .....
- A proper machine parseable sysfs based alternative for
/proc/interrupts.
- ACPI support for the GICV3-ITS and ARM interrupt remapping
- Two new irq chips from the ARM SoC zoo: STM32-EXTI and MVEBU-PIC
- A new irq chip for the JCore (SuperH)
