To handle netpoll properly, the driver must only handle TX packets
during NAPI. Handling RX events cause warnings and errors in
netpoll mode. The ndo_poll_controller() method should call
napi_schedule() directly so that a NAPI weight of zero will be used
during netpoll mode.
The bnxt_en driver supports 2 ring modes: combined, and separate rx/tx.
In separate rx/tx mode, the ndo_poll_controller() method will only
process the tx rings. In combined mode, the rx and tx completion
entries are mixed in the completion ring and we need to drop the rx
entries and recycle the rx buffers.
Add a function bnxt_force_rx_discard() to handle this in netpoll mode
when we see rx entries in combined ring mode.

The function, skb_complete_tx_timestamp(), used to allow passing in a
NULL pointer for the time stamps, but that was changed in commit
62bccb8cdb69051b95a55ab0c489e3cab261c8ef ("net-timestamp: Make the
clone operation stand-alone from phy timestamping"), and the existing
call sites, all of which are in the dp83640 driver, were fixed up.
Even though the kernel-doc was subsequently updated in commit
7a76a021cd5a292be875fbc616daf03eab1e6996 ("net-timestamp: Update
skb_complete_tx_timestamp comment"), still a bug fix from Manfred
Rudigier came into the driver using the old semantics. Probably
Manfred derived that patch from an older kernel version.
This fix should be applied to the stable trees as well.

When a RAID set was created on dm-raid version < 1.9.0 (old RAID
superblock format), all of the new 1.9.0 members of the superblock are
uninitialized (zero) -- including the device sectors member needed to
support shrinking.
All the other accesses to superblock fields new in 1.9.0 were reviewed
and verified to be properly guarded against invalid use. The 'sectors'
member was the only one used when the superblock version is < 1.9.
Don't access the superblock's >= 1.9.0 'sectors' member unconditionally.
Also add respective comments.

The F54 driver is currently only using the first 6 bytes of F54 so there is
no need to read all 27 bytes. Some Dell systems (Dell XP13 9333 and
similar) have an issue with the touchpad or I2C bus when reading reports
larger then 16 bytes. Reads larger then 16 bytes are reported in two HID
reports. Something about the back to back reports seems to cause the next
read to report incorrect data. This results in F30 failing to load and the
click button failing to work.
Previous issues with the I2C controller or touchpad were addressed in:

A previous set of patches "cxl: Add support for Coherent Accelerator
Interface Architecture 2.0" has introduced a new support for the CAPI
cards. These patches have been tested on Simulation environment and
quite a bit of them have been tested on real hardware.
This patch brings new fixes after a series of tests carried out on new
equipment:
- Add POWER9 definition.
- Re-enable any masked interrupts when the AFU is not activated
after resetting the AFU.
- Remove the api cxl_is_psl8/9 which is no longer useful.
- Do not dump CAPI1 registers.
- Rewrite cxl_is_page_fault() function.
- Do not register slb callack on P9.

Passthru macvlans directly change the mac address of the lower
level device. That's OK, but after the macvlan is deleted,
the lower device is left with changed address and one needs to
reboot to bring back the origina HW addresses.
This scenario is actually quite common with passthru macvtap devices.
This patch attempts to solve this, by storing the mac address
of the lower device in macvlan_port structure and keeping track of
it through the changes.
After this patch, any changes to the lower device mac address
done trough the macvlan device, will be reverted back. Any
changs done directly to the lower device mac address will be kept.

When a lower device of the passthru macvlan changes it's address,
passthru macvlan is supposed to change it's own address as well.
However, that doesn't happen correctly because the check in
macvlan_addr_busy() will catch the fact that the lower level
(port) mac address is the same as the address we are trying to
assign to the macvlan, and return an error. As a reasult,
the address of the passthru macvlan device is never changed.
The same thing happens when the user attempts to change the
mac address of the passthru macvlan.
The simple solution appers to be to not check against
the lower device in case of passthru macvlan device, since
the 2 addresses are _supposed_ to be the same.

There are number of problems with configuration peer
network device in absence of IFLA_VETH_PEER attributes
where attributes for main network device shared with
peer.
First it is not feasible to configure both network
devices with same MAC address since this makes
communication in such configuration problematic.
This case can be reproduced with following sequence:
# ip link add address 02:11:22:33:44:55 type veth
# ip li sh
...
26: veth0@veth1: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc \
noop state DOWN mode DEFAULT qlen 1000
link/ether 00:11:22:33:44:55 brd ff:ff:ff:ff:ff:ff
27: veth1@veth0: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc \
noop state DOWN mode DEFAULT qlen 1000
link/ether 00:11:22:33:44:55 brd ff:ff:ff:ff:ff:ff
Second it is not possible to register both main and
peer network devices with same name, that happens
when name for main interface is given with IFLA_IFNAME
and same attribute reused for peer.
This case can be reproduced with following sequence:
# ip link add dev veth1a type veth
RTNETLINK answers: File exists
To fix both of the cases check if corresponding netlink
attributes are taken from peer_tb when valid or
name based on rtnl ops kind and random address is used.

The commit ("net/phy: micrel: Add workaround for bad autoneg") fixes an
autoneg failure case by resetting the hardware. This turns off
intterupts. Things will work themselves out if the phy polls, as it will
figure out it's state during a poll. However if the phy uses only
intterupts, the phy will stall, since interrupts are off. This patch
fixes the issue by calling config_intr after resetting the phy.

Commit f406270bf73d ("ACPI / scan: Set the visited flag for all
enumerated devices") caused that two group of special SPI or I2C
devices do not enumerate. SPI and I2C devices are expected to be
enumerated by the SPI and I2C subsystems but change caused that
acpi_bus_attach() marks those devices with acpi_device_set_enumerated().
First group of devices are matched using Device Tree compatible property
with special _HID "PRP0001". Those devices have matched scan handler,
acpi_scan_attach_handler() retuns 1 and acpi_bus_attach() marks them
with acpi_device_set_enumerated().
Second group of devices without valid _HID such as "LNXVIDEO" have
device->pnp.type.platform_id set to zero and change again marks them
with acpi_device_set_enumerated().
Fix this by flagging the SPI and I2C devices during struct acpi_device
object initialization time and let the code in acpi_bus_attach() to go
through the device_attach() and acpi_default_enumeration() path for all
SPI and I2C devices.

Otherwise, when the dec_count() is called it can cause the dm-io

gic_read_count(), gic_write_compare() and gic_write_cpu_compare() are
often used in a sequence to update the compare register with a count
value increased by a small offset.
With small delta values used to update the compare register, the time to
update function trace for these operations may be longer than the update
timeout leading to update failure.

Kalle Valo says:
====================
wireless-drivers fixes for 4.12
Two important fixes for brcmfmac. The rest of the brcmfmac patches are
either code preparation and fixing a new build warning.
brcmfmac
* fix a NULL pointer dereference during resume
* fix a NULL pointer dereference with USB devices, a regression from
v4.12-rc1

When having the skb pointer in the first descriptor, stmmac_tx_clean
can get called at a moment where the IP has only cleared the own bit
of the first descriptor, thus freeing the skb, even though there can
be several descriptors whose buffers point into the same skb.
By simply moving the skb pointer from the first descriptor to the last
descriptor, a skb will get freed only when the IP has cleared the
own bit of all the descriptors that are using that skb.

Somehow two copies of the line 'up_write(&vf->efx->filter_sem);' got into
efx_ef10_sriov_set_vf_vlan(). This would put the mutex in a bad state and
cause all subsequent down attempts to hang.

As it turns out more than just Armada 370 and XP support using GPIO
lines as PWM lines. For example the Armada 38x family has the same
hardware support. As such "marvell,armada-370-xp-gpio" for the
compatible string is a misnomer.
Change the compatible string to "marvell,armada-370-gpio" before the
driver makes it out of the -rc stage. This also follows the practice of
using only the first device family supported as part of the name.
Also update the documentation and comments in the code accordingly.

Setting these bits causes libinput to fail to initialize the device;
setting BTN_TOUCH and BTN_TOOL_FINGER causes it to treat the mouse as a
touchpad, and it then refuses to continue when it discovers ABS_X is not
set.
This breaks all known Wayland compositors, as well as Xorg when the
libinput driver is being used.
This reverts commit f4b65b9563216b3e01a5cc844c3ba68901d9b195.
