The dwmac4_set_umac_addr() takes a struct mac_device_info as
the first parameter, but is being passed a ioaddr instead from
dwmac4_set_filter(). Fix the warning/bug by changing the first
parameter.
drivers/net/ethernet/stmicro/stmmac/dwmac4_core.c:159:46: warning: incorrect type in argument 1 (different address spaces)

In commit f9476a6c6d0c ("drm/i915: Refactor platform specifics out of
intel_get_shared_dpll()"), the ibx_get_dpll() function lacked an error
check, that can lead to a NULL pointer dereference when trying to enable
three pipes.

Blue flame is a latency enhancement feature that allows the driver to
write the packet data directly to the NIC's registers thus making the
read of the packet data from host memory redundant.
We maintain a quota for the blue flame which is reloaded whenever we
identify that the hardware is processing send requests and processes
them fast enough so by the time we post the next send request it was
able to process all the pending ones. This indicates that the hardware
is capable of processing more blue flame requests efficiently. The blue
flame quota is decremented whenever we send using blue flame.
The current code erroneously clears the budget if we did not use blue
flame for the current post send operation and we fix it here.

In RoCE, the RDMA-CM needs the node guid to establish connection
between nodes.
Today, the node guid exposed to mlx5 Ethernet VFs is zero, therefore
RDMA-CM on the VF is broken.
Whenever the administrator sets a MAC for a VF, derive the node guid
from it and set it as well in the following way:
MAC: e4:1d:2d:b3:f4:01 -> node_guid: e4:1d:2d:ff:fe:b3:f4:01

Reorder vport enable flow to mark the vport as enabled before calling
the vport change handler which was modified to handle the case for
when vport is not enabled.
This fixes the case for when the PF netdev is open before sriov is
enabled, once sriov is enabled at esw_enable_vport,
esw_vport_change_handle_locked didn't read the PF context since it
thought the PF vport was not enabled.
When we enable the vport, arming for events is not required anymore,
since it's done on the vport change handle

The mlx5 flow-steering API (mlx5_create_flow_table/group/rule) never
returns null pointer on error. Even if it was doing that, checking
for IS_ERR_OR_NULL(p) and then returning PTR_ERR(p) would have cause
bugs, since PTR_ERR(NULL) --> success, crash.
To make things more robust and protect against related future bugs,
convert all IS_ERR_OR_NULL checks on returned values to IS_ERR.

Many Intel systems the BIOS declares a SystemIO OpRegion below the SMBus
PCI device as can be seen in ACPI DSDT table from Lenovo Yoga 900:
Device (SBUS)
{
OperationRegion (SMBI, SystemIO, (SBAR << 0x05), 0x10)
Field (SMBI, ByteAcc, NoLock, Preserve)
{
HSTS, 8,
Offset (0x02),
HCON, 8,
HCOM, 8,
TXSA, 8,
DAT0, 8,
DAT1, 8,
HBDR, 8,
PECR, 8,
RXSA, 8,
SDAT, 16
}
There are also bunch of AML methods that that the BIOS can use to access
these fields. Most of the systems in question AML methods accessing the
SMBI OpRegion are never used.
Now, because of this SMBI OpRegion many systems fail to load the SMBus
driver with an error looking like one below:
ACPI Warning: SystemIO range 0x0000000000003040-0x000000000000305F
conflicts with OpRegion 0x0000000000003040-0x000000000000304F
(\_SB.PCI0.SBUS.SMBI) (20160108/utaddress-255)
ACPI: If an ACPI driver is available for this device, you should use
it instead of the native driver
The reason is that this SMBI OpRegion conflicts with the PCI BAR used by
the SMBus driver.
It turns out that we can install a custom SystemIO address space handler
for the SMBus device to intercept all accesses through that OpRegion. This
allows us to share the PCI BAR with the AML code if it for some reason is
using it. We do not expect that this OpRegion handler will ever be called
but if it is we print a warning and prevent all access from the SMBus
driver itself.

The function is unflattening device sub-tree blob if @dad passed to
the function is valid. Currently, this functionality is used by PPC
PowerNV PCI hotplug driver only. There are possibly multiple nodes
in the first level of depth, fdt_next_node() bails immediately when
@depth becomes negative before the second device node can be probed
successfully. It leads to the device nodes except the first one won't
be unflattened successfully.
This fixes the issue by setting the initial depth (@inital_depth) to
1 when this function is called to unflatten device sub-tree blob. No
logic changes when this function is used to unflatten non-sub-tree
blob.

When rtnl_fill_ifinfo() is called for a certain netdevice it queries its
various parameters such as switch id and physical port name. The
function might get called in an atomic context, which means the
underlying driver must not sleep during the query operation.
Don't query the device and sleep during ndo_get_phys_port_name(), but
instead store the needed parameters in port creation time.

When a port is created following a split / unsplit we need to map it to
the correct module and lane, enable it and then continue to initialize
its various parameters such as MTU and VLAN filters.
Under certain conditions, such as trying to split ports at the bottom
row of the front panel by four, we get firmware errors.
After evaluating this with the firmware team it was decided to alter the
split / unsplit flow, so that first all the affected ports are mapped,
then enabled and finally each is initialized separately.
Fix the split / unsplit flow by first mapping and enabling all the
affected ports. Newer firmware versions will support both flows.

Powerplay uses cgs to load the firmware so add a function
to release it as well to avoid leaking it on driver unload.

should fist halt engine, and then doing the register
programing, and later unhalt engine, and finally run
ring_test.
this help fix reloading driver hang issue of SDMA
ring
original sequence is wrong for it programing engine
after unhalt, which will lead to fault behavior when
doing driver reloading after unloaded.
