To avoid potential compilation problems, replaced the badly written
MB_TO_SECTS() macro (missing parenthesis around the argument use) with
the inline function mb_to_sects(). And while at it, simplify the
calculation of the total number of zones of the device using the
round_up() macro.

The published errata specify the maximum allowed SPI frequency to be
max 85% of (FSYSCLK/2). So there's no need to track known bad clock
settings in the driver. As the setup of known good values is a bit
tricky, keep them.

The R-Car System Controller (SYSC) driver registers PM domains from an
early_initcall(). It does not use a platform driver, as secondary CPU
startup on R-Car H1 needs to control the CPU power domains, before
initialization of the driver framework.
As fw_devlink only considers devices, it does not know that the System
Controller is ready. Hence probing of on-chip devices that are part of
the SYSC PM domain fails if fw_devlink is enabled:
probe deferral - supplier e6180000.system-controller not ready
Fix this by setting the OF_POPULATED flag for the SYSC device node after
successful initialization. This will make of_link_to_phandle() ignore
the SYSC device node as a dependency, and consumer devices will be
probed again.

Currently there are only two types of in-kernel nexthop notification.
The two are distinguished by the 'is_grp' boolean field in 'struct
nh_notifier_info'.
As more notification types are introduced for more next-hop group types, a
boolean is not an easily extensible interface. Instead, convert it to an
enum.

Stop maintaining the skb_send_q list for TRANS_HIPER sockets.
Not only is it extra overhead, but keeping around a list of skb clones
means that we later also have to match the ->sk_txnotify() calls
against these clones and free them accordingly.
The current matching logic (comparing the skbs' shinfo location) is
frustratingly fragile, and breaks if the skb's head is mangled in any
sort of way while passing from dev_queue_xmit() to the device's
HW queue.
Also adjust the interface for ->sk_txnotify(), to make clear that we
don't actually care about any skb internals.

When do_qdio() returns with an unexpected error, qeth_flush_buffers()
kicks off a recovery action.
In such a case there's no point in starting TX completion processing,
the device gets torn down anyway. So take a closer look at do_qdio()'s
return value, and skip the TX completion processing accordingly.

As part of the TX queue selection for af_iucv skbs,
qeth_l3_get_cast_type_rcu() ends up calling qeth_get_ether_cast_type().
Which is rather fragile, since such skbs don't have a proper ETH header
and we rely on it being zeroed out in the right places. Add a separate
case for ETH_P_AF_IUCV instead that does the right thing.
When later building the HW header for such skbs, don't hard-code the
cast type but follow the same path as for other protocol types. Here
the cast type should naturally come from the skb's queue mapping.

Replace our home-grown helper with the more robust vlan_get_protocol().
This is pretty much a 1:1 replacement, we just need to pass around a

qeth_l3_hard_start_xmit() to a switch statement.

The only time we transfer data (rather than issuing a command) out
of the AP->command TX endpoint is when we're clearing the hardware
pipeline. All that's needed is a "small" data buffer, and its
contents aren't even important.
For convenience, we just transfer a command structure in this case
(it's already mapped for DMA). The TRE is added to a transaction
using ipa_cmd_ip_tag_status_add(), but we ignore the size value
provided to that function. So just get rid of the size argument.

We only send a tagged packet from the AP->command TX endpoint when
we're clearing the hardware pipeline. And when we receive the
tagged packet we don't care what the actual tag value is.
Stop passing a tag value to ipa_cmd_ip_tag_status_add(), and just
encode 0 as the tag sent. Fix the function that encodes the tag so
it uses the proper byte ordering.

There are times, such as when the modem crashes, when we issue
commands to clear the IPA hardware pipeline. These commands include
a data transfer command that delivers a small packet directly to the
default (AP<-LAN RX) endpoint.
The places that do this wait for the transactions that contain these
commands to complete, but the pipeline can't be assumed clear until
the sent packet has been *received*.
The small transfer will be delivered with a status structure, and
that status will indicate its tag is valid. This is the only place
we send a tagged packet, so we use the tag to determine when the
pipeline clear packet has arrived.
Add a completion to the IPA structure to to be used to signal
the receipt of a pipeline clear packet. Create a new function
ipa_cmd_pipeline_clear_wait() that will wait for that completion.
Reinitialize the completion whenever pipeline clear commands are
added to a transaction. Extend ipa_endpoint_status_tag() to check
whether a packet whose status contains a valid tag was sent from the
AP->command TX endpoint, and if so, signal the new IPA completion.
Have all callers of ipa_cmd_pipeline_clear_add() wait for the
pipeline clear indication after the transaction that clears the
pipeline has completed.

status indicates its tag field is valid. The endpoint parameter is
not yet used.
Call this from ipa_status_drop_packet(), and drop the packet if the
status indicates the tag was valid. Pass the endpoint pointer to
ipa_status_drop_packet(), and rename it ipa_endpoint_status_drop().

There is a set of functions and symbols related to performing
"tag_process" immediate commands to clear the IPA pipeline. The
name is related to one of the commands issued when doing this, but
it doesn't really convey the overall purpose of taking this action.
The purpose is to take some steps to "clear out" the hardware
pipeline, and to wait until that process completes, to ensure the
IPA hardware is in a well-defined state.
Rename these symbols to use "pipeline_clear" in their names instead.
Add some comments to explain a bit more about what's going on.

The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'e100_alloc()', GFP_KERNEL can be used because
it is only called from the probe function and no lock is acquired.

Pass through mode is to allow packets in MAP format to be passed
on to the stack. rmnet driver can be used to process and demultiplex
these packets.
Pass through mode can be enabled when the device is in raw ip mode only.
Conversely, raw ip mode cannot be disabled when pass through mode is
enabled.
Userspace can use pass through mode in conjunction with rmnet driver
through the following steps-
1. Enable raw ip mode on qmi_wwan device
2. Enable pass through mode on qmi_wwan device
3. Create a rmnet device with qmi_wwan device as real device using netlink

While we do handle the additional cursor sizes introduced in NVE4, it looks
like we accidentally broke this when converting over to use Nvidia's
display headers. Since we now use NVVAL in dispnv50/head907d.c in order to
format the value for the cursor layout and NVD9 only had one byte reserved
vs. the 2 bytes reserved in later generations, we end up accidentally
stripping the second bit in the cursor layout format parameter - causing us
to set the wrong cursor size.
This fixes that by adding our own curs_set hook for 917d which uses the
NV917D headers.

Nvidia hardware doesn't actually support using tiling formats with the
cursor plane, only linear is allowed. In the future, we should write a
testcase for this.

Commit f844eb485eb056ad3b67e49f95cbc6c685a73db4 introduced a regression for
NV50, which lead to visual artifacts, tearing and eventual crashes.
In the changes of f844eb485eb056ad3b67e49f95cbc6c685a73db4 only the first line
was correctly translated to the new NVIDIA header macros:
- PUSH_NVSQ(push, NV827C, 0x0110, 0,
- 0x0114, 0);
+ PUSH_MTHD(push, NV827C, SET_PROCESSING,
+ NVDEF(NV827C, SET_PROCESSING, USE_GAIN_OFS, DISABLE));
The lower part ("0x0114, 0") was probably omitted by accident.
This patch restores the push of the missing data and fixes the regression.

====================
mlx5 subfunction support
Parav Pandit says:
This patchset introduces support for mlx5 subfunction (SF).
A subfunction is a lightweight function that has a parent PCI function on
which it is deployed. mlx5 subfunction has its own function capabilities
and its own resources. This means a subfunction has its own dedicated
queues(txq, rxq, cq, eq). These queues are neither shared nor stolen from
the parent PCI function.
When subfunction is RDMA capable, it has its own QP1, GID table and rdma
resources neither shared nor stolen from the parent PCI function.
A subfunction has dedicated window in PCI BAR space that is not shared
with the other subfunctions or parent PCI function. This ensures that all
class devices of the subfunction accesses only assigned PCI BAR space.
A Subfunction supports eswitch representation through which it supports tc
offloads. User must configure eswitch to send/receive packets from/to
subfunction port.
Subfunctions share PCI level resources such as PCI MSI-X IRQs with
their other subfunctions and/or with its parent PCI function.
Subfunction support is discussed in detail in RFC [1] and [2].
RFC [1] and extension [2] describes requirements, design and proposed
plumbing using devlink, auxiliary bus and sysfs for systemd/udev
support. Functionality of this patchset is best explained using real
examples further below.
overview:
--------
A subfunction can be created and deleted by a user using devlink port
add/delete interface.
A subfunction can be configured using devlink port function attribute
before its activated.
When a subfunction is activated, it results in an auxiliary device on
the host PCI device where it is deployed. A driver binds to the
auxiliary device that further creates supported class devices.
example subfunction usage sequence:
-----------------------------------
Change device to switchdev mode:
$ devlink dev eswitch set pci/0000:06:00.0 mode switchdev
Add a devlink port of subfunction flavour:
$ devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88
Configure mac address of the port function:
$ devlink port function set ens2f0npf0sf88 hw_addr 00:00:00:00:88:88
Now activate the function:
$ devlink port function set ens2f0npf0sf88 state active
Now use the auxiliary device and class devices:
$ devlink dev show
pci/0000:06:00.0
auxiliary/mlx5_core.sf.4
$ ip link show
127: ens2f0np0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether 24:8a:07:b3:d1:12 brd ff:ff:ff:ff:ff:ff
altname enp6s0f0np0
129: p0sf88: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether 00:00:00:00:88:88 brd ff:ff:ff:ff:ff:ff
$ rdma dev show
43: rdmap6s0f0: node_type ca fw 16.29.0550 node_guid 248a:0703:00b3:d112 sys_image_guid 248a:0703:00b3:d112
44: mlx5_0: node_type ca fw 16.29.0550 node_guid 0000:00ff:fe00:8888 sys_image_guid 248a:0703:00b3:d112
After use inactivate the function:
$ devlink port function set ens2f0npf0sf88 state inactive
Now delete the subfunction port:
$ devlink port del ens2f0npf0sf88
