Remove the empty implementation of sriov_configure() and set the
sriov_configure member of the pci_driver structure to NULL.
This way, if a user tries to enable VFs on a device, when kernel and
driver are built with CONFIG_PCI_IOV=n, the kernel reports an error
message saying that the driver does not support SRIOV configuration via
sysfs.

Replace vf_mask type with unsigned long to avoid a stack-out-of-bound.

omap_crypto_cleanup() currently copies data from sg to orig if either
copy flag is set. However OMAP_CRYPTO_SG_COPIED means that sg refers
to the same pages as orig, truncated to len bytes. There is no need
to copy in this case.
Only copy data if the OMAP_CRYPTO_DATA_COPIED flag is set.

This reverts commit a955318fe67e ("stmmac: align RX buffers"),
which breaks at least one platform (Nvidia Jetson-X1), causing
packet corruption. This is 100% reproducible, and reverting
the patch results in a working system again.
Given that it is "only" a performance optimisation, let's
return to a known working configuration until we can have a
good understanding of what is happening here.

1) New index member of struct rxe_queue was introduced but not zeroed so
the initial value of index may be random.
2) The current index is not masked off to index_mask.
In this case producer_addr() and consumer_addr() will get an invalid
address by the random index and then accessing the invalid address
triggers the following panic:
"BUG: unable to handle page fault for address: ffff9ae2c07a1414"

schedule_delayed_work does not push back the work if it was already
scheduled before, so amdgpu_device_delay_enable_gfx_off ran ~100 ms
after the first time GFXOFF was disabled and re-enabled, even if GFXOFF
was disabled and re-enabled again during those 100 ms.
This resulted in frame drops / stutter with the upcoming mutter 41
release on Navi 14, due to constantly enabling GFXOFF in the HW and
disabling it again (for getting the GPU clock counter).
To fix this, call cancel_delayed_work_sync when the disable count
transitions from 0 to 1, and only schedule the delayed work on the
reverse transition, not if the disable count was already 0. This makes
sure the delayed work doesn't run at unexpected times, and allows it to
be lock-free.
v2:
* Use cancel_delayed_work_sync & mutex_trylock instead of
mod_delayed_work.
v3:
* Make amdgpu_device_delay_enable_gfx_off lock-free (Christian König)
v4:
* Fix race condition between amdgpu_gfx_off_ctrl incrementing
adev->gfx.gfx_off_req_count and amdgpu_device_delay_enable_gfx_off
checking for it to be 0 (Evan Quan)

When non-secure priorities are used, compared to the raw priority set,
the value read back from RPR is also right-shifted by one and the
highest bit set.
Add a macro to do the modifications to the raw priority when doing the
comparison against the RPR value. This corrects the pseudo-NMI behavior
when non-secure priorities in the GIC are used. Tested on 5.10 with
the "IPI as pseudo-NMI" series [1] applied on MT8195.

When disable_irq_nosync for an interrupt is called from within its
interrupt handler, this interrupt is only marked as disabled with the
intention to mask it when it triggers again.
The AIC hardware however automatically masks the interrupt when it is read.
aic_irq_eoi then unmasks it again if it's not disabled *and* not masked.
This results in a state mismatch between the hardware state and the
state kept in irq_data: The hardware interrupt is masked but
IRQD_IRQ_MASKED is not set. Any further calls to unmask_irq will directly
return and the interrupt can never be enabled again.
Fix this by keeping the hardware and irq_data state in sync by unmasking in
aic_irq_eoi if and only if the irq_data state also assumes the interrupt to
be unmasked.

The devlink dev info command reports version information about the
device and firmware running on the board. This includes the "board.id"
field which is supposed to represent an identifier of the board design.
The ice driver uses the Product Board Assembly identifier for this.
In some cases, the PBA is not present in the NVM. If this happens,
devlink dev info will fail with an error. Instead, modify the
ice_info_pba function to just exit without filling in the context
buffer. This will cause the board.id field to be skipped. Log a dev_dbg
message in case someone wants to confirm why board.id is not showing up
for them.

spinlocks which in turn calls kzalloc(size, GFP_KERNEL) which is

Currently dpaa2_switch_takedown has a funny name and does not do the
opposite of dpaa2_switch_init, which makes probing fail when we need to
handle an -EPROBE_DEFER.
A sketch of what dpaa2_switch_init does:
dpsw_open
dpaa2_switch_detect_features
dpsw_reset
for (i = 0; i < ethsw->sw_attr.num_ifs; i++) {
dpsw_if_disable
dpsw_if_set_stp
dpsw_vlan_remove_if_untagged
dpsw_if_set_tci
dpsw_vlan_remove_if
}
dpsw_vlan_remove
alloc_ordered_workqueue
dpsw_fdb_remove
dpaa2_switch_ctrl_if_setup
When dpaa2_switch_takedown is called from the error path of
dpaa2_switch_probe(), the control interface, enabled by
dpaa2_switch_ctrl_if_setup from dpaa2_switch_init, remains enabled,
because dpaa2_switch_takedown does not call
dpaa2_switch_ctrl_if_teardown.
Since dpaa2_switch_probe might fail due to EPROBE_DEFER of a PHY, this
means that a second probe of the driver will happen with the control
interface directly enabled.
This will trigger a second error:
[ 93.273528] fsl_dpaa2_switch dpsw.0: dpsw_ctrl_if_set_pools() failed
[ 93.281966] fsl_dpaa2_switch dpsw.0: fsl_mc_driver_probe failed: -13
[ 93.288323] fsl_dpaa2_switch: probe of dpsw.0 failed with error -13
Which if we investigate the /dev/dpaa2_mc_console log, we find out is
caused by:
[E, ctrl_if_set_pools:2211, DPMNG] ctrl_if must be disabled
So make dpaa2_switch_takedown do the opposite of dpaa2_switch_init (in
reasonable limits, no reason to change STP state, re-add VLANs etc), and
rename it to something more conventional, like dpaa2_switch_teardown.

Make changes to MAC address dependent on the response of PF.
Disallow changes to HW MAC address and MAC filter from untrusted
VF, thanks to that ping is not lost if VF tries to change MAC.
Add a new field in iavf_mac_filter, to indicate whether there
was response from PF for given filter. Based on this field pass
or discard the filter.
If untrusted VF tried to change it's address, it's not changed.
Still filter was changed, because of that ping couldn't go through.

Without this patch, ATR does not work. Receive/transmit uses queue
selection based on SW DCB hashing method.
If traffic classes are not configured for PF, then use
netdev_pick_tx function for selecting queue for packet transmission.
Instead of calling i40e_swdcb_skb_tx_hash, call netdev_pick_tx,
which ensures that packet is transmitted/received from CPU that is
running the application.
Reproduction steps:
1. Load i40e driver
2. Map each MSI interrupt of i40e port for each CPU
3. Disable ntuple, enable ATR i.e.:
ethtool -K $interface ntuple off
ethtool --set-priv-flags $interface flow-director-atr
4. Run application that is generating traffic and is bound to a
single CPU, i.e.:
taskset -c 9 netperf -H 1.1.1.1 -t TCP_RR -l 10
5. Observe behavior:
Application's traffic should be restricted to the CPU provided in
taskset.

Two legacy PCI sysfs objects "legacy_io" and "legacy_mem" were updated
to use an unified address space in the commit 636b21b50152 ("PCI: Revoke
mappings like devmem"). This allows for revocations to be managed from
a single place when drivers want to take over and mmap() a /dev/mem
range.
Following the update, both of the sysfs objects should leverage the
iomem_get_mapping() function to get an appropriate address range, but
only the "legacy_io" has been correctly updated - the second attribute
seems to be using a wrong variable to pass the iomem_get_mapping()
function to.
Thus, correct the variable name used so that the "legacy_mem" sysfs
object would also correctly call the iomem_get_mapping() function.
