While using net_dim, a dim_sample was used without ever initializing the
comps value. Added use of DIV_ROUND_DOWN_ULL() to prevent potential
overflow, it should not be a problem to save the final result in an int
because after the division by epms the value should not be larger than a
few thousand.

SFP modules connected using the SGMII interface have their own PHYs which
are handled by the struct phylink's phydev field. On the other hand, for
the modules connected using 1000Base-X interface that field is not set.
Since commit ce0aa27ff3f6 ("sfp: add sfp-bus to bridge between network
devices and sfp cages") phylink_start() ends up setting the phydev field
using the sfp-bus infrastructure, which eventually calls phy_start() on it,
and then calling phy_start() again on the same phydev from phylink_start()
itself. Similar call sequence holds for phylink_stop(), only in the reverse
order. This results in WARNs during network interface bringup and shutdown
when a copper SFP module is connected, as phy_start() and phy_stop() are
called twice in a row for the same phy_device:

We have observed rcar_canfd driver entering IRQ storm under high load,
with following scenario:
- rcar_canfd_global_interrupt() in entered due to Rx available,
- napi_schedule_prep() is called, and sets NAPIF_STATE_SCHED in state
- Rx fifo interrupts are masked,
- rcar_canfd_global_interrupt() is entered again, this time due to
error interrupt (e.g. due to overflow),
- since scheduled napi poller has not yet executed, condition for calling
napi_schedule_prep() from rcar_canfd_global_interrupt() remains true,
thus napi_schedule_prep() gets called and sets NAPIF_STATE_MISSED flag
in state,
- later, napi poller function rcar_canfd_rx_poll() gets executed, and
calls napi_complete_done(),
- due to NAPIF_STATE_MISSED flag in state, this call does not clear
NAPIF_STATE_SCHED flag from state,
- on return from napi_complete_done(), rcar_canfd_rx_poll() unmasks Rx
interrutps,
- Rx interrupt happens, rcar_canfd_global_interrupt() gets called
and calls napi_schedule_prep(),
- since NAPIF_STATE_SCHED is set in state at this time, this call
returns false,
- due to that false return, rcar_canfd_global_interrupt() returns
without masking Rx interrupt
- and this results into IRQ storm: unmasked Rx interrupt happens again
and again is misprocessed in the same way.
This patch fixes that scenario by unmasking Rx interrupts only when
napi_complete_done() returns true, which means it has cleared
NAPIF_STATE_SCHED in state.

CONFIG_CAN_LEDS is deprecated. When trying to use the generic netdev
trigger as suggested, there's a small inconsistency with the link
property: The LED is on initially, stays on when the device is brought
up, and then turns off (as expected) when the device is brought down.
Make sure the LED always reflects the state of the CAN device.

The onboard sky2 NIC on ASUS P6T WS PRO doesn't work after PM resume
due to the infamous IRQ problem. Disabling MSI works around it, so
let's add it to the blacklist.
Unfortunately the BIOS on the machine doesn't fill the standard
DMI_SYS_* entry, so we pick up DMI_BOARD_* entries instead.

The following scenario was encountered during testing of logical
partition mobility on pseries partitions with bonded ibmvnic
adapters in LACP mode.
1. Driver receives a signal that the device has been
swapped, and it needs to reset to initialize the new
device.
2. Driver reports loss of carrier and begins initialization.
3. Bonding driver receives NETDEV_CHANGE notifier and checks
the slave's current speed and duplex settings. Because these
are unknown at the time, the bond sets its link state to
BOND_LINK_FAIL and handles the speed update, clearing
AD_PORT_LACP_ENABLE.
4. Driver finishes recovery and reports that the carrier is on.
5. Bond receives a new notification and checks the speed again.
The speeds are valid but miimon has not altered the link
state yet. AD_PORT_LACP_ENABLE remains off.
Because the slave's link state is still BOND_LINK_FAIL,
no further port checks are made when it recovers. Though
the slave devices are operational and have valid speed
and duplex settings, the bond will not send LACPDU's. The
simplest fix I can see is to force another speed check
in bond_miimon_commit. This way the bond will update
AD_PORT_LACP_ENABLE if needed when transitioning from
BOND_LINK_FAIL to BOND_LINK_UP.

vrf_process_v4_outbound() and vrf_process_v6_outbound() do routing

Case:

2) Packet size is greater then 255.

As pointed out by Firo Yang, a netdev tx timeout may trigger just before an
ethtool set_channels operation is started. be_tx_timeout(), which dumps
some queue structures, is not written to run concurrently with
be_update_queues(), which frees/allocates those queues structures. Add some
synchronization between the two.

This patch fixes an issue seen on Power systems with bnx2x which results
in the skb is NULL WARN_ON in bnx2x_free_tx_pkt firing due to the skb
pointer getting loaded in bnx2x_free_tx_pkt prior to the hw_cons
load in bnx2x_tx_int. Adding a read memory barrier resolves the issue.

The RX power read from the SFP uses units of 0.1uW. This must be
scaled to units of uW for HWMON. This requires a divide by 10, not the
current 100.
With this change in place, sensors(1) and ethtool -m agree:
sff2-isa-0000
Adapter: ISA adapter
in0: +3.23 V
temp1: +33.1 C

The commit b3aa14f02254 ("iommu: remove the mapping_error dma_map_ops
method") incorrectly changed the checking from dma_ops_alloc_iova() in
map_sg() causes a crash under memory pressure as dma_ops_alloc_iova()
never return DMA_MAPPING_ERROR on failure but 0, so the error handling
is all wrong.

Pull ARM Devicetree updates from Olof Johansson:
"We continue to see a lot of new material. I've highlighted some of it
below, but there's been more beyond that as well.
One of the sweeping changes is that many boards have seen their ARM
Mali GPU devices added to device trees, since the DRM drivers have now
been merged.
So, with the caveat that I have surely missed several great
contributions, here's a collection of the material this time around:
New SoCs:
- Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53)
- TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA)
- Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53)
New Boards / platforms:
- Aspeed BMC support for a number of new server platforms
- Kontron SMARC SoM (several i.MX6 versions)
- Novtech's Meerkat96 (i.MX7)
- ST Micro Avenger96 board
- Hardkernel ODROID-N2 (Amlogic G12B)
- Purism Librem5 devkit (i.MX8MQ)
- Google Cheza (Qualcomm SDM845)
- Qualcomm Dragonboard 845c (Qualcomm SDM845)
- Hugsun X99 TV Box (Rockchip RK3399)
- Khadas Edge/Edge-V/Captain (Rockchip RK3399)
Updated / expanded boards and platforms:
- Renesas r7s9210 has a lot of new peripherals added
- Fixes and polish for Rockchip-based Chromebooks
- Amlogic G12A has a lot of peripherals added
- Nvidia Jetson Nano sees various fixes and improvements, and is now
at feature parity with TX1"
