NAND chips require a bit of time to take the NAND operation into
account and set the BUSY bit in the STATUS reg. Make sure we don't poll
the STATUS reg too early in nand_soft_waitrdy().

Two nouveau crasher/deadlock fixes.
* 'linux-4.17' of git://github.com/skeggsb/linux:
drm/nouveau: Fix deadlock in nv50_mstm_register_connector()
drm/nouveau/ttm: don't dereference nvbo::cli, it can outlive client

Currently; we're grabbing all of the modesetting locks before adding MST
connectors to fbdev. This isn't actually necessary, and causes a
deadlock as well:

Taking example from i915, the only time we need to hold any modesetting
locks is when changing the port on the mstc, and in that case we only
need to hold the connection mutex.

GFP_TRANSHUGE tries very hard to allocate huge pages, which can result
in long delays with high memory pressure. I have observed firefox
freezing for up to around a minute due to this while restic was taking
a full system backup.
Since we don't really need huge pages, use GFP_TRANSHUGE_LIGHT |
__GFP_NORETRY instead, in order to fail quickly when there are no huge
pages available.
Set __GFP_KSWAPD_RECLAIM as well, in order for huge pages to be freed
up in the background if necessary.
With these changes, I'm no longer seeing freezes during a restic backup.

USB controller ASM1042 stops working after commit de3ef1eb1cd0 (PM /
core: Drop run_wake flag from struct dev_pm_info).
The device in question is not power managed by platform firmware,
furthermore, it only supports PME# from D3cold:
Capabilities: [78] Power Management version 3
Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0-,D1-,D2-,D3hot-,D3cold+)
Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME-
Before commit de3ef1eb1cd0, the device never gets runtime suspended.
After that commit, the device gets runtime suspended to D3hot, which can
not generate any PME#.
usb_hcd_pci_probe() unconditionally calls device_wakeup_enable(), hence
device_can_wakeup() in pci_dev_run_wake() always returns true.
So pci_dev_run_wake() needs to check PME wakeup capability as its first
condition.
In addition, change wakeup flag passed to pci_target_state() from false
to true, because we want to find the deepest state different from D3cold
that the device can still generate PME#. In this case, it's D0 for the
device in question.

Since commit a92a08499b1f "r8169: improve runtime pm in general and
suspend unused ports" interfaces w/o link are runtime-suspended after
10s. On systems where drivers take longer to load this can lead to the
situation that the interface is runtime-suspended already when it's
initially brought up.
This shouldn't be a problem because rtl_open() resumes MAC/PHY.
However with at least one chip version the interface doesn't properly
come up, as reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=199549
The vendor driver uses a delay to give certain chip versions some
time to resume before starting the PHY configuration. So let's do
the same. I don't know which chip versions may be affected,
therefore apply this delay always.
This patch was reported to fix the issue for RTL8168h.
I was able to reproduce the issue on an Asus H310I-Plus which also
uses a RTL8168h. Also in my case the patch fixed the issue.

====================
pull-request: can 2018-05-08
this is a pull request for 7 patches for net/master.
The first patch is by Jakob Unterwurzacher and increases the severity of
bus-off messages in the generic CAN device infrastructure. The next two patches
are by Uwe Kleine-König and fix the endianess detection in the flexcan driver.
Jimmy Assarsson's patch for the kvaser driver corrects the stats counter for
dropped tx-messages. Geert Uytterhoeven provides one patch and Sergei Shtylyov
two patches for the rcan_canfd device tree binding description.

An update from ieee802154 for your *net* tree.
Two fixes for the mcr20a driver, which was being added in the 4.17 merge window,
by Gustavo and myself.
The atusb driver got a change to GFP_KERNEL where no GFP_ATOMIC is needed by
Jia-Ju.
The last and most important fix is from Alex to get IPv6 reassembly working
again for the ieee802154 6lowpan adaptation. This got broken in 4.16 so please

Fix `[drm:intel_enable_lvds] *ERROR* timed out waiting for panel to
power on` in kernel log at boot time.
Toshiba Satellite Z930 laptops needs between 1 and 2 seconds to power
on its screen during Intel i915 DRM initialization. This currently
results in a `[drm:intel_enable_lvds] *ERROR* timed out waiting for
panel to power on` message appearing in the kernel log during boot
time and when stopping the machine.
This change increases the timeout of the `intel_enable_lvds` function
from 1 to 5 seconds, letting enough time for the Satellite 930 LCD
screen to power on, and suppressing the error message from the kernel
log.
This patch has been successfully tested on Linux 4.14 running on a
Toshiba Satellite Z930.
[vsyrjala: bump the timeout from 2 to 5 seconds to match the DP
code and properly cover the max hw timeout of ~4 seconds, and
drop the comment about the specific machine since this is not
a particulary surprising issue, nor specific to that one machine]

readout
During state readout we first read out the pipe src size, store
that information in the user mode h/vdisplay, but later on we overwrite
that with the actual crtc timings. That makes our read out crtc state
inconsistent with itself when the BIOS has enabled the panel fitter to
scale the pipe contents. Let's preserve the pipe src size based
information in the user mode to make things consistent again.
This fixes a problem introduced by commit a2936e3d9a9c ("drm/i915:
Use drm_mode_get_hv_timing() to populate plane clip rectangle")
where the inconsistent state is now leading the plane clipping code
to report a failure on account the plane dst coordinates not matching
the user mode size. Previously we did the plane clipping based on
the pipe src size instead and thus never noticed the inconsistency.
The failure manifests as a WARN:

On intel_dp_compute_config() we were calculating the needed vco
for eDP on gen9 and we stashing it in
intel_atomic_state.cdclk.logical.vco
However few moments later on intel_modeset_checks() we fully
replace entire intel_atomic_state.cdclk.logical with
dev_priv->cdclk.logical fully overwriting the logical desired
vco for eDP on gen9.
So, with wrong VCO value we end up with wrong desired cdclk, but
also it will raise a lot of WARNs: On gen9, when we read
CDCLK_CTL to verify if we configured properly the desired
frequency the CD Frequency Select bits [27:26] == 10b can mean
337.5 or 308.57 MHz depending on the VCO. So if we have wrong
VCO value stashed we will believe the frequency selection didn't
stick and start to raise WARNs of cdclk mismatch.

In commit 88462d2a7830 ("can: flexcan: Remodel FlexCAN register r/w APIs
for big endian FlexCAN controllers.") the following logic was
implemented:
if the dt property "big-endian" is given or
the device is compatible to "fsl,p1010-flexcan":
use big-endian mode;
else
use little-endian mode;
This relies on commit d50f4630c2e1 ("arm: dts: Remove p1010-flexcan
compatible from imx series dts") which was applied a few commits later.
Without this commit (or an old device tree used for booting a new
kernel) the flexcan devices on i.MX25, i.MX28, i.MX35 and i.MX53 match
the 'the device is compatible to "fsl,p1010-flexcan"' test and so are
switched erroneously to big endian mode.
Instead of the check above put a quirk in devtype data and rely on
of_match_device yielding the most compatible match

bus-off is usually caused by hardware malfunction or configuration error
(baud rate mismatch) and causes a complete loss of communication.
Increase the "bus-off" message's severity from netdev_dbg() to
netdev_info() to make it visible to the user.
A can interface going into bus-off is similar in severity to ethernet's
"Link is Down" message, which is also printed at info level.
It is debatable whether the the "restarted" message should also be
changed to netdev_info() to make the interface state changes
comprehensible from the kernel log. I have chosen to keep the
"restarted" message at dbg for now as the "bus-off" message should be
enough for the user to notice and investigate the problem.

Driver should use pci_alloc_irq_vectors return value to correct number
of allocated vectors and napi instances. Otherwise it'll panic later
in pci_irq_vector.

resources in a correct sequence when error happens.

Testing of 6f88284f3bd7 ("net: dsa: mv88e6xxx: Add MDIO interrupts for

nvme_free_ns_head will access the nvme_subsystem.ns_ida
which has been freed by __nvme_release_subsystem after all the
reference of nvme_subsystem have been released by nvme_free_ctrl.
This could cause memory corruption.
