Remove pci_clear_master to simplify the code,
the bus-mastering is also cleared in do_pci_disable_device,
like this:
./drivers/pci/pci.c:2197
static void do_pci_disable_device(struct pci_dev *dev)
{
u16 pci_command;
pci_read_config_word(dev, PCI_COMMAND, &pci_command);
if (pci_command & PCI_COMMAND_MASTER) {
pci_command &= ~PCI_COMMAND_MASTER;
pci_write_config_word(dev, PCI_COMMAND, pci_command);
}
pcibios_disable_device(dev);
}.
And dev->is_busmaster is set to 0 in pci_disable_device.

For multi-chip devices, we need to make sure the all dice in the device
are ready. The cypress_nor_sr_ready_and_clear() reads SR in each die and
returns true only when all dice are ready. This function also takes care
for program or erase error handling by reusing spansion_nor_clear_sr().
To do that, spansion_nor_clear_sr() is moved to top.

device support
For multi-chip devices, we can use 512B page only when the all dice are
configured as 512B page size. The volatile register address is calculated
by using the volatile register addresses retrieved from the SCCR tables
and the (configuration) register offset.
The location of cypress_nor_set_page_size() call is moved from
post_bfpt_fixup() to post_sfdp_fixup(), because the number of dice and
volatile register offset are parsed in the optional SCCR tables.

SCCR map for multi-chip devices contains the number of additional dice in
the device and register offset values for each additional dice.
spi_nor_parse_sccr_mc() is added to determine the number of dice and
volatile register offset for each die. The volatile register offset table
may already be allocated and contains offset value for die-0 via SCCR map
parse. So, we should use devm_krealloc() to expand the table with
preserving die-0 offset.

In use of multi-chip devices, we need to access registers in each die for
configuration and status check. The number of dice in the device and
volatile register offsets for each die are essential to iterate register
access ops.
The volatile register offset for the first die resides in the 1st DWORD
of SCCR map. Allocate the table and copy the offset value.
The table may be allocated when the SCCR map for multi-chip is parsed.
Since we cannot assume SCCR parse is always in ahead of SCCR multi-chip,
we need to check if the table is already allocated or not.

Multi die flashes like s25hl02gt need to determine the page_size at
run-time by querying a configuration register for each die. Since the
number of dice is determined in an optional SFDP table, SCCR MC, the
page size configuration must be done in the post_sfdp hook. Allow
post_sfdp to return errors, as reading the configuration register might
return errors.

On a fragmented system it's normal that order 3 allocations will
sometimes fail, especially atomic ones. The driver handles these
failures fine and the WARN just creates spam in the logs for this
case. The __GFP_NOWARN flag is exactly for this situation, so add it
to the allocation.
NOTE: my testing is on a 5.15 system, but there should be no reason
that this would be fundamentally different on a mainline kernel.

anarion_config_dt()
Always return struct anarion_gmac * from anarion_config_dt().
In the case where ctl_block was an error pointer it was being
returned directly. Which sparse flags as follows:
.../dwmac-anarion.c:73:24: warning: incorrect type in return expression (different address spaces)
.../dwmac-anarion.c:73:24: expected struct anarion_gmac *
.../dwmac-anarion.c:73:24: got void [noderef] __iomem *[assigned] ctl_block
Avoid this by converting the error pointer to an error.
And then reversing the conversion.
As a side effect, the error can be used for logging purposes,
subjectively, leading to a minor cleanup.
No functional change intended.

Use __iomem annotation the register base: the ctl_block field of struct
anarion_gmac. I believe this is the normal practice for such variables.
By doing so some casting is avoided.
And sparse no longer reports:

Add support for J784S4 CPSW9G
This series adds a new compatible to am65-cpsw driver for the CPSW9G
instance of the CPSW Ethernet Switch on TI's J784S4 SoC which has 8
external ports and 1 internal host port.
The CPSW9G instance supports QSGMII and USXGMII modes for which driver
support is added.
Additionally, the interface mode specific configurations are moved to the
am65_cpsw_nuss_mac_config() callback. Also, a TODO comment is added for
verifying whether in-band mode is necessary for 10 Mbps RGMII mode.
NOTE:
I have verified that the mac_config() operations are preserved across
link up and link down events for SGMII and USXGMII mode with the new
implementation in this series, as suggested by:
Russell King <linux@armlinux.org.uk>
For patches 1 and 3 of this series, I believe that the following tag:

with minor changes made by me.

assume the following setup on a single machine:
1. An openvswitch instance with one bridge and default flows
2. two network namespaces "server" and "client"
3. two ovs interfaces "server" and "client" on the bridge
4. for each ovs interface a veth pair with a matching name and 32 rx and
tx queues
5. move the ends of the veth pairs to the respective network namespaces
6. assign ip addresses to each of the veth ends in the namespaces (needs
to be the same subnet)
7. start some http server on the server network namespace
8. test if a client in the client namespace can reach the http server
when following the actions below the host has a chance of getting a cpu
stuck in a infinite loop:
1. send a large amount of parallel requests to the http server (around
3000 curls should work)
2. in parallel delete the network namespace (do not delete interfaces or
stop the server, just kill the namespace)
there is a low chance that this will cause the below kernel cpu stuck
message. If this does not happen just retry.
Below there is also the output of bpftrace for the functions mentioned
in the output.
The series of events happening here is:
1. the network namespace is deleted calling
`unregister_netdevice_many_notify` somewhere in the process
2. this sets first `NETREG_UNREGISTERING` on both ends of the veth and
then runs `synchronize_net`
3. it then calls `call_netdevice_notifiers` with `NETDEV_UNREGISTER`
4. this is then handled by `dp_device_event` which calls
`ovs_netdev_detach_dev` (if a vport is found, which is the case for
the veth interface attached to ovs)
5. this removes the rx_handlers of the device but does not prevent
packages to be sent to the device
6. `dp_device_event` then queues the vport deletion to work in
background as a ovs_lock is needed that we do not hold in the
unregistration path
7. `unregister_netdevice_many_notify` continues to call
`netdev_unregister_kobject` which sets `real_num_tx_queues` to 0
8. port deletion continues (but details are not relevant for this issue)
9. at some future point the background task deletes the vport
If after 7. but before 9. a packet is send to the ovs vport (which is
not deleted at this point in time) which forwards it to the
`dev_queue_xmit` flow even though the device is unregistering.
In `skb_tx_hash` (which is called in the `dev_queue_xmit`) path there is
a while loop (if the packet has a rx_queue recorded) that is infinite if
`dev->real_num_tx_queues` is zero.
To prevent this from happening we update `do_output` to handle devices
without carrier the same as if the device is not found (which would
be the code path after 9. is done).
Additionally we now produce a warning in `skb_tx_hash` if we will hit
the infinite loop.

Now that there's display support, there is no reason to assume the default
mode for Adreno should be headless. Keep it like that for boards that
previously enabled it, so as not to create regressions though.

The following example forces veristat to loop indefinitely:
$ cat two-ok
file_name,prog_name,verdict,total_states
file-a,a,success,12
file-b,b,success,67
$ cat add-failure
file_name,prog_name,verdict,total_states
file-a,a,success,12
file-b,b,success,67
file-b,c,failure,32
$ veristat -C two-ok add-failure
<does not return>
The loop is caused by handle_comparison_mode() not checking if `base`
variable points to `fallback_stats` prior advancing joined results
using `base`.

After commit d6e6286a12e7 ("libbpf: disassociate section handler on explicit
bpf_program__set_type() call"), bpf_program__set_type() will force cleanup
the program's SEC() definition, this commit fixed the test helper but missed
the bpftool, which leads to bpftool prog autoattach broken as follows:
$ bpftool prog load spi-xfer-r1v1.o /sys/fs/bpf/test autoattach
Program spi_xfer_r1v1 does not support autoattach, falling back to pinning
This patch fix bpftool to set program type only if it differs.

perf_event with type=PERF_TYPE_RAW and config=0x1b00 turned out to be not
reliable in ensuring LBR is active. Thus, test_progs:get_branch_snapshot is
not reliable in some systems. Replace it with PERF_COUNT_HW_CPU_CYCLES
event, which gives more consistent results.
