If the sector number is too high, dm_table_find_target() should return a
pointer to a zeroed dm_target structure (the caller should test it with
dm_target_is_valid).
However, for some table sizes, the code in dm_table_find_target() that
performs btree lookup will access out of bound memory structures.
Fix this bug by testing the sector number at the beginning of
dm_table_find_target(). Also, add an "inline" keyword to the function
dm_table_get_size() because this is a hot path.

A timing hazard exists when an early fork/exec thread begins
exiting and sets its mm pointer to NULL while a separate core
tries to update the section information.
This commit ensures that the mm pointer is not NULL before
setting its section parameters. The arguments provided by
commit 11ce4b33aedc ("ARM: 8672/1: mm: remove tasklist locking
from update_sections_early()") are equally valid for not
requiring grabbing the task_lock around this check.

The new API for registering a gpio_irq_chip along with a
gpio_chip has a different semantic ordering than the old
API which added the irqchip explicitly after registering
the gpio_chip.
Move the calls to add the gpio_irq_chip *last* in the
function, so that the different hooks setting up OF and
ACPI and machine gpio_chips are called *before* we try
to register the interrupts, preserving the elder semantic
order.
This cropped up in the PL061 driver which used to work
fine with no special ACPI quirks, but started to misbehave
using the new API.

When refactoring port lookup for DSS outputs, commit d17eb4537a7e
("drm/omap: Factor out common init/cleanup code for output devices")
incorrectly hardcoded usage of DT port 0. This breaks operation for SDI
(which uses the DT port 1) and DPI outputs other than DPI0 (which are
not used in mainline DT sources).
Fix this by using the port number from the output omap_dss_device
of_ports field.

qxl has two modes: "native" (used by the drm driver) and "vga" (vga
compatibility mode, typically used for boot display and firmware
framebuffers).
Accessing any vga ioport will switch the qxl device into vga mode.
The qxl driver never does that, but other drivers accessing vga ports
can trigger that too and therefore disturb qxl operation. So aquire
the legacy vga ioports from vgaarb to avoid that.
Reproducer: Boot kvm guest with both qxl and i915 vgpu, with qxl being
first in pci scan order.
v2: Skip this for secondary qxl cards which don't have vga mode in the
first place (Frediano).

(and then as user dummy)
$ dd if=/dev/urandom bs=1M count=50 of=/mnt/dummy/foo
$ chgrp plugdev /mnt/dummy/foo
and saw:

While I had thought I had fixed this issue in:
commit 342406e4fbba ("drm/nouveau/i2c: Disable i2c bus access after
->fini()")
It turns out that while I did fix the error messages I was seeing on my
P50 when trying to access i2c busses with the GPU in runtime suspend, I
accidentally had missed one important detail that was mentioned on the
bug report this commit was supposed to fix: that the CPU would only lock
up when trying to access i2c busses _on connected devices_ _while the
GPU is not in runtime suspend_. Whoops. That definitely explains why I
was not able to get my machine to hang with i2c bus interactions until
now, as plugging my P50 into it's dock with an HDMI monitor connected
allowed me to finally reproduce this locally.
Now that I have managed to reproduce this issue properly, it looks like
the problem is much simpler then it looks. It turns out that some
connected devices, such as MST laptop docks, will actually ACK i2c reads
even if no data was actually read:
[ 275.063043] nouveau 0000:01:00.0: i2c: aux 000a: 1: 0000004c 1
[ 275.063447] nouveau 0000:01:00.0: i2c: aux 000a: 00 01101000 10040000
[ 275.063759] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000001
[ 275.064024] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000
[ 275.064285] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000
[ 275.064594] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000
Because we don't handle the situation of i2c ack without any data, we
end up entering an infinite loop in nvkm_i2c_aux_i2c_xfer() since the
value of cnt always remains at 0. This finally properly explains how
this could result in a CPU hang like the ones observed in the
aforementioned commit.
So, fix this by retrying transactions if no data is written or received,
and give up and fail the transaction if we continue to not write or
receive any data after 32 retries.

The VDSO update for CLOCK_BOOTTIME has a overflow issue as it shifts the
nanoseconds based boot time offset left by the clocksource shift. That
overflows once the boot time offset becomes large enough. As a consequence
CLOCK_BOOTTIME in the VDSO becomes a random number causing applications to
misbehave.
Fix it by storing a timespec64 representation of the offset when boot time
is adjusted and add that to the MONOTONIC base time value in the vdso data
page. Using the timespec64 representation avoids a 64bit division in the
update code.

40GbE Intel Wired LAN Driver Updates 2019-08-22
This series contains updates to i40e driver only.
Arnd Bergmann reduces the stack usage which was causing warnings on
32-bit architectures due to large structure sizes for 2 functions
getting inlined, so use noinline_for_stack to prevent the compilers from
combining the 2 functions.
Mauro S. M. Rodrigues fixes an issue when reading an EEPROM from SFP
modules that comply with SFF-8472 but do not implement the Digital
Diagnostic Monitoring (DDM) interface for i40e.
Huhai found we were not checking the return value for configuring the
transmit ring and continuing with XDP configuration of the transmit
ring.
Beilei fixes an issue of shifting signed 32-bit integers.
Sylwia adds support for "packet drop mode" to the MAC configuration for
admin queue command. This bit controls the behavior when a no-drop
packet is blocking a TC queue. Adds support for persistent LLDP by
checking the LLDP flag and reading the LLDP from the NVM when enabled.
Adrian fixes the "recovery mode" check to take into account which device
we are on, since x710 devices have 4 register values to check for status
and x722 devices only have 2 register values to check.
Piotr Azarewicz bumps the supported firmware API version to 1.9 which
extends the PHY access admin queue command support.
Jake makes sure the traffic class stats for a VEB are reset when the VEB
stats are reset.
Slawomir fixes a NULL pointer dereference where the VSI pointer was not
updated before passing it to the i40e_set_vf_mac() when the VF is in a
reset state, so wait for the reset to complete.
Grzegorz removes the i40e_update_dcb_config() which was not using the
correct NVM reads, so call i40e_init_dcb() in its place to correctly
update the DCB configuration.
Piotr Kwapulinski expands the scope of i40e_set_mac_type() since this is
needed during probe to determine if we are in recovery mode. Fixed the
driver reset path when in recovery mode.
Marcin fixed an issue where we were breaking out of a loop too early
when trying to get the PHY capabilities.
v2: Combined patch 7 & 9 in the original series, since both patches
bumped firmware API version. Also combined patches 12 & 13 in the
original series, since one increased the scope of checking for MAC
and the follow-on patch made use of function within the new scope.

The outer poll loop checks for whether we need to reschedule, and
returns to userspace if we do. However, it's possible to get stuck
in the inner loop as well, if the CPU we are running on needs to
reschedule to finish the IO work.
Add the need_resched() check in the inner loop as well. This fixes
a potential hang if the kernel is configured with

For TLS WQEs, metadata info did not include num_bytes. Due to this issue,
tx_tls_dump_bytes counter did not increment.
Modify tx_fill_wi() to fill num bytes. When it is called for non-traffic
WQE, zero is expected.

When fw fatal error occurs, poll health() first detects and reports on a
fw error. Afterwards, it detects and reports on the fw fatal error
itself.
That can cause a long delay in fw fatal error handling which waits in a
queue for the fw error handling to be finished. The fw error handle will
try asking for fw core dump command while fw in fatal state may not
respond and driver will wait for command timeout.
Changing the flow to detect and handle first fw fatal errors and only if
no fatal error detected look for a fw error to handle.

Crdump repeats itself every chunk of 256bytes.
That is due to bug of missing progressing offset while copying the data

Driver waits after issuing a reset. When a reset takes too long a driver
gives up. Implemented by invoking PF reset in a loop. After defined
number of unsuccessful PF reset trials it returns error.
Without this patch PF reset fails when NIC is in recovery mode.
So make i40e_set_mac_type() public. i40e driver requires i40e_set_mac_type()
to be public. It is required for recovery mode handling. Without this patch
recovery mode could not be detected in i40e_probe().

This patch removes function i40e_update_dcb_config(). Instead of
i40e_update_dcb_config() we use i40e_init_dcb(), which implements the

Add update to the VSI pointer passed to the i40e_set_vf_mac function.
If VF is in reset state the driver waits in i40e_set_vf_mac function
for the reset to be complete, yet after reset the vsi pointer
that was passed into this function is no longer valid.
The patch updates local VSI pointer directly from pf->vsi array,
by using the id stored in VF pointer (lan_vsi_idx).
Without this commit the driver might occasionally invoke general
protection fault in kernel and disable the OS entirely.

Function check_recovery_mode had wrong if statement.
Now we check proper FWS1B register values, which are responsible for
the recovery mode. Recovery mode has 4 values for x710 and 2 for x722.
That's why we need 6 different flags which are defined in the code.
Now in the if statement, we recognize type of mac address
and register value.
Without those changes driver could show wrong state.

This patch adds "drop mode" parameter to set mac config AQ command.
This bit controls the behavior when a no-drop packet is blocking a TC
queue.
0 – The PF driver is notified.
1 – The blocking packet is dropped and then the PF driver is notified.
