Create a helper function for clearing VPGEN_VFRTRIG as this needs to be
done on reset to notify the VF that we are done resetting it. Also, it
needs to be done on SR-IOV initialization/creation in case it was left
in a bad state after SR-IOV tear down.

Currently ice_ena_vf_mappings() does all of the VF's MSIX and queue
mapping in one function. This makes it hard to digest. Fix this by
creating a new function for enabling MSIX mappings and one for enabling

Also, rename some variables in the functions for clarity.

If register_netdev() fails, the driver will attempt to cleanup the
q_vectors and inadvertently trigger a kernel BUG due to a NULL pointer
dereference.
This occurs because cleaning up q_vectors attempts to call
netif_napi_del on napi_structs which were never initialized.
Resolve this by releasing the netdev in ice_cfg_netdev and setting
vsi->netdev to NULL. This ensures that after ice_cfg_netdev fails the
state is rewound to match as if ice_cfg_netdev was never called.

If ice_init_interrupt_scheme fails, ice_probe will jump to clearing up
the interrupts. This can lead to some static analysis tools such as the
compiler sanitizers complaining about double free problems.
Since ice_init_interrupt_scheme already unrolls internally on failure,
there is no need to call ice_clear_interrupt_scheme when it fails. Add
a new unroll label and use that instead.

In certain designs, it is possible to add a battery on a populated i2c
bus without an sbs compliant charger. In that case, the battery will
unnecessarily and sometimes undesirably master the bus trying to write
info in the charger.
It is observed in many occasion that these battery "broadcasts" are even
corrupting other ongoing master to slave communication. I.e. the
multi-master support in the battery is inadequate.
Thankfully, the CHARGER_MODE bit allows designers to disable that SBS
battery behaviour.
This needs to be done once when the battery is first seen on the bus.

The SBS battery implements SMBus block reads. Currently the
driver "emulates" this by doing an I2C byte read for the
length followed by an I2C block read. The I2C subsystem
actually provides a proper API for doing SMBus block reads,
which can and should be used instead. The current implementation
does not properly handle packet error checking (PEC).
This change requires, that I2C bus drivers support I2C_M_RECV_LEN
or directly provide the SMBus API to access device manufacturer
and model name.

DMA mapped pages, including those pinned by mdev vendor drivers, might
get unpinned and unmapped while migration is active and device is still
running. For example, in pre-copy phase while guest driver could access
those pages, host device or vendor driver can dirty these mapped pages.
Such pages should be marked dirty so as to maintain memory consistency
for a user making use of dirty page tracking.
To get bitmap during unmap, user should allocate memory for bitmap, set
it all zeros, set size of allocated memory, set page size to be
considered for bitmap and set flag VFIO_DMA_UNMAP_FLAG_GET_DIRTY_BITMAP.

- Start dirty pages tracking while migration is active
- Stop dirty pages tracking.
- Get dirty pages bitmap. Its user space application's responsibility to
copy content of dirty pages from source to destination during migration.
To prevent DoS attack, memory for bitmap is allocated per vfio_dma
structure. Bitmap size is calculated considering smallest supported page
size. Bitmap is allocated for all vfio_dmas when dirty logging is enabled
Bitmap is populated for already pinned pages when bitmap is allocated for
a vfio_dma with the smallest supported page size. Update bitmap from
pinning functions when tracking is enabled. When user application queries
bitmap, check if requested page size is same as page size used to
populated bitmap. If it is equal, copy bitmap, but if not equal, return

With 'commit 461c1a7d4733 ("gpiolib: override irq_enable/disable")' gpiolib
overrides irqchip's irq_enable and irq_disable callbacks. If irq_disable
callback is implemented then genirq takes unlazy path to disable irq.
Underlying irqchip may not want to implement irq_disable callback to lazy
disable irq when client drivers invokes disable_irq(). By overriding
irq_disable callback, gpiolib ends up always unlazy disabling IRQ.
Allow gpiolib to lazy disable IRQs by overriding irq_disable callback only
if irqchip implemented irq_disable. In cases where irq_disable is not
implemented irq_mask is overridden. Similarly override irq_enable callback
only if irqchip implemented irq_enable otherwise irq_unmask is overridden.

Alas the method trigger_all_cpu_backtrace() isn't exported by the
kernel, but we need to have it called in case of the bus errors detected
to get a better description of a possible cause of the error. Let's
disable the ability to build the driver as a loadable kernel module then.
Note In future the driver will support the AXI-bus interconnect capability,
so we'd have to make it built into the kernel anyway.

100GbE Intel Wired LAN Driver Updates 2020-05-27
This series contains updates to the ice driver only.
Jesse fixes a number of issues, starting with fixing the remaining
signed versus unsigned comparison issues. Cleaned up an unused code
define. Fixed the implementation of the manage MAC write command, to
simplify it by using a simple array to represent the MAC address when
writing it.
Paul fixes the setting of the VF default LAN address, by removing a
check that assumed that the address had been deleted and zeroed.
Surabhi prevents a memory leak on filter management initialization
failures and during queue initialization and buffer allocation failures.
Brett adds additional receive error counters that are reported by
ethtool. Fixed the enabling and disabling of VLAN stripping when the
PVID has been set.
Evan fixes a race condition between the firmware and software, which can
occur between the admin queue setup and the first command sent.
Marta fixes the driver when XDP transmit rings are destroyed, also make
sure the XDP transmit queues are also destroyed. Update the statistics
when XDP transmit programs are loaded and packets are sent. Changed the
number of XDP transmit queues to match the number of receive queues,
instead of matching the number of transmit queues.
Bruce avoids undefined behavior by not writing the 8-bit element
init_q_state with the associated internal-to-hardware field which is
122-bits.
Anirudh (Ani) refactors the receive checksum checks.
Krzysztof notifies the user if the fill queue is not long enough to
prepare all buffers before packet processing starts and allocates the
buffers during the NAPI poll.

Updates highlights:
1) From Vu Pham (8): Support VM traffics failover with bonded VF

traffic over direct/fast VF path and failing over to slower
paravirtualized path using the following features:

|_________________|
Summary:
--------
Problem statement:
------------------
Currently in above topology, when netfailover device is configured using
VFs and eswitch VF representors, and when traffic fails over to stand-by
VF which is exposed using macvtap device to guest VM, eswitch fails to
switch the traffic to the stand-by VF representor. This occurs because
there is no knowledge at eswitch level of the stand-by representor
device.
Solution:
---------
Using standard bonding driver, a bond netdevice is created over VF
representor device which is used for offloading tc rules.
Two VF representors are bonded together, one for the passthrough VF
device and another one for the stand-by VF device.
With this solution, mlx5 driver listens to the failover events
occuring at the bond device level to failover traffic to either of
the active VF representor of the bond.
a. VM with netfailover device of VF pass-thru (PT) device and virtio-net
paravirtualized device with same MAC-address to handle failover
traffics at VM level.
b. Host bond is active-standby mode, with the lower devices being the VM
VF PT representor, and the representor of the 2nd VF to handle
failover traffics at Hypervisor/V-Switch OVS level.
- During the steady state (fast datapath): set the bond active
device to be the VM PT VF representor.
- During failover: apply bond failover to the second VF representor
device which connects to the VM non-accelerated path.
c. E-Switch ingress/egress ACL tables to support failover traffics at
E-Switch level
I. E-Switch egress ACL with forward-to-vport rule:
- By default, eswitch vport egress acl forward packets to its
counterpart NIC vport.
- During port failover, the egress acl forward-to-vport rule will
be added to e-switch vport of passive/in-active slave VF
representor
to forward packets to other e-switch vport ie. the active slave
representor's e-switch vport to handle egress "failover"
traffics.
- Using lower change netdev event to detect a representor is a
lower
dev (slave) of bond and becomes active, adding egress acl
forward-to-vport rule of all other slave netdevs to forward to
this
representor's vport.
- Using upper change netdev event to detect a representor unslaving
from bond device to delete its vport's egress acl forward-to-vport
rule.
II. E-Switch ingress ACL metadata reg_c for match
- Bonded representors' vorts sharing tc block have the same
root ingress acl table and a unique metadata for match.
- Traffics from both representors's vports will be tagged with same
unique metadata reg_c.
- Using upper change netdev event to detect a representor
enslaving/unslaving from bond device to setup shared root ingress
acl and unique metadata.
2) From Alex Vesker (2): Slpit RX and TX lock for parallel rule insertion in
software steering
3) Eli Britstein (2): Optimize performance for IPv4/IPv6 ethertype use the HW
ip_version register rather than parsing eth frames for ethertype.

Credit-Based Shaper as described in the IEEE 8021Q-2018 document.
First generation has 10 shapers, freely assignable to any of the 4
external ports and 8 traffic classes, and second generation has 16
shapers.
The Credit-Based Shaper tables are accessed through the dynamic
reconfiguration interface, so we have to restore them manually after a
switch reset. The tables are backed up by the static config only on
P/Q/R/S, and we don't want to add custom code only for that family,
since the procedure that is in place now works for both.
Tested with the following commands:
data_rate_kbps=67000
port_transmit_rate_kbps=1000000
idleslope=$data_rate_kbps
sendslope=$(($idleslope - $port_transmit_rate_kbps))
locredit=$((-0x80000000))
hicredit=$((0x7fffffff))

Some battery fuel gauges know when the battery needs to
be recalibrated before providing usable values. This
should be reported via the health property.
