After commit 419d6efc50e9, kernel cannot be crashed in the namei
path. However, corrupted nameoff can do harm in the process of
readdir for scenerios without dm-verity as well. Fix it now.

If a device has an exclusion range specified in the IVRS
table, this region needs to be reserved in the iova-domain
of that device. This hasn't happened until now and can cause
data corruption on data transfered with these devices.
Treat exclusion ranges as reserved regions in the iommu-core
to fix the problem.

edram is not part of uncore and there is no requirement for the
detection to be done before we initialize the uncore functions. The
first check on HAS_EDRAM is in the ggtt_init path, so move it to
i915_driver_init_hw, where other dram-related detection happens.
While at it, save the size in MB instead of the capabilities because the
size is the only thing we look at outside of the init function.

The vid_pll_div is a programmable fractional divider, but vendor gives a
limited of known configuration value and it's corresponding fraction.
Thus when at reset value (0) or unknown value, we cannot determine the
result rate.
The initial behaviour was to print a warning, but the warning triggers
at each boot and when the clock tree is refreshed.
This patch moves the print to debug and returns 0 instead of the
parent rate.

According to Intel GFX PRM on 01.org, plane surface address can be updated
synchronously or asynchronously. Synchronous flip will hold plane surface
address update to start of next vsync, which is current implementation.
Asynchronous flip will update the address as soon as possible. Without
async flip, some 3D application could not reach better performance and
the maximum performance is no higher than vsync frequency.
The patch enables the async flip on plane surface address mmio update,
and increment flip count correctly.
With async flip enabled, some 3D applications have significant performance
improvement. i.e. 3DMark Ice Storm has a 300%~400% increment on score.

According to Intel GFX PRM on 01.org, the MI_DISPLAY_FLIP command can
either request display plane flip synchronously or asynchronously.
In synchronous flip, flip will be hold until next vsync, which
is not implemented yet in GVT. In asynchronous flip, flip will happen

The patch enables the sync flip on handling MI_DISPLAY_FLIP,

When calling this method, interrupts MUST be enabled. This is because

For netconsole we can't guarantee IRQ state, let's just

Intel Wired LAN Driver Fixes 2019-03-26
This series contains updates to igb, ixgbe, i40e and fm10k.
Jake fixes an issue with PTP in i40e where a previous commit resulted
in a regression where the driver would interpret small negative
adjustments as large positive additions, resulting in incorrect
behavior.
Arvind Sankar fixes an issue in igb where a previous commit would cause
a warning in the PCI pm core and resulted in pci_pm_runtime_suspend
would not call pci_save_state or pci_finish_runtime_suspend.
Ivan Vecera fixes MDIO bus registration with ixgbe, where the driver was
ignoring errors returned when registering and would leave the pointer in
a NULL state which triggered a BUG when un-registering.
Stefan Assmann fixes the check for Wake-On-LAN for i40e, which only
supports magic packet.
Yue Haibing fixes a potential NULL pointer de-reference in fm10k by
adding a simple check if the value is NULL.

SPI GPIO device has more than just "cs-gpio" property in its node and
would request those GPIOs as a part of its initialization. To avoid
applying CS-specific quirk to all of them add a check to make sure
that propname is "cs-gpios".

Pull s390 fixes from Martin Schwidefsky:
"Improvements and bug fixes for 5.1-rc2:
- Fix early free of the channel program in vfio
- On AP device removal make sure that all messages are flushed with
the driver still attached that queued the message
- Limit brk randomization to 32MB to reduce the chance that the heap
of ld.so is placed after the main stack
- Add a rolling average for the steal time of a CPU, this will be
needed for KVM to decide when to do busy waiting
- Fix a warning in the CPU-MF code
- Add a notification handler for AP configuration change to react
faster to new AP devices"
