As part of preparation for HWS, added missing definitions
in qp.h and fs_core.h:
- FS_FT_FDB_RX/TX table types that are used by HWS in addition
to an existing FS_FT_FDB
- MLX5_WQE_CTRL_INITIATOR_SMALL_FENCE that is used by HWS to
require fence in WQE

Add mlx5_ifc definitions that are required for HWS support.
Note that due to change in the mlx5_ifc_flow_table_context_bits
structure that now includes both SWS and HWS bits in a union,
this patch also includes small change in one of SWS files that
was required for compilation.

Always call igb_xdp_ring_update_tail() under __netif_tx_lock, add a comment
and lockdep assert to indicate that. This is needed to share the same TX
ring between XDP, XSK and slow paths. Furthermore, the current XDP
implementation is racy on tail updates.

The description of function ice_find_vsi_list_entry says:
Search VSI list map with VSI count 1
However, since the blamed commit (see Fixes below), the function no
longer checks vsi_count. This causes a problem in ice_add_vlan_internal,
where the decision to share VSI lists between filter rules relies on the
vsi_count of the found existing VSI list being 1.
The reproducing steps:
1. Have a PF and two VFs.
There will be a filter rule for VLAN 0, referring to a VSI list
containing VSIs: 0 (PF), 2 (VF#0), 3 (VF#1).
2. Add VLAN 1234 to VF#0.
ice will make the wrong decision to share the VSI list with the new
rule. The wrong behavior may not be immediately apparent, but it can
be observed with debug prints.
3. Add VLAN 1234 to VF#1.
ice will unshare the VSI list for the VLAN 1234 rule. Due to the
earlier bad decision, the newly created VSI list will contain
VSIs 0 (PF) and 3 (VF#1), instead of expected 2 (VF#0) and 3 (VF#1).
4. Try pinging a network peer over the VLAN interface on VF#0.
This fails.

(Unsafe, by the way. Lacks rule_lock when dumping in ice_remove_vlan.)
Michal Swiatkowski added to the explanation that the bug is caused by
reusing a VSI list created for VLAN 0. All created VFs' VSIs are added
to VLAN 0 filter. When a non-zero VLAN is created on a VF which is already
in VLAN 0 (normal case), the VSI list from VLAN 0 is reused.
It leads to a problem because all VFs (VSIs to be specific) that are
subscribed to VLAN 0 will now receive a new VLAN tag traffic. This is
one bug, another is the bug described above. Removing filters from
one VF will remove VLAN filter from the previous VF. It happens a VF is
reset. Example:
- creation of 3 VFs
- we have VSI list (used for VLAN 0) [0 (pf), 2 (vf1), 3 (vf2), 4 (vf3)]
- we are adding VLAN 100 on VF1, we are reusing the previous list
because 2 is there
- VLAN traffic works fine, but VLAN 100 tagged traffic can be received
on all VSIs from the list (for example broadcast or unicast)
- trust is turning on VF2, VF2 is resetting, all filters from VF2 are
removed; the VLAN 100 filter is also removed because 3 is on the list
- VLAN traffic to VF1 isn't working anymore, there is a need to recreate
VLAN interface to readd VLAN filter
One thing I'm not certain about is the implications for the LAG feature,
which is another caller of ice_find_vsi_list_entry. I don't have a
LAG-capable card at hand to test.

Our driver uses devres to manage resources, in particular we call
pcim_enable_device(), what also means we express the intent to get
automatic pci_disable_device() call at driver removal. Manual calls to
pci_disable_device() misuse the API.
Recent commit (see "Fixes" tag) has changed the removal action from
conditional (silent ignore of double call to pci_disable_device()) to
unconditional, but able to catch unwanted redundant calls; see cited
"Fixes" commit for details.
Since that, unloading the driver yields following warn+splat:

When adding a switch filter (such as a MAC or VLAN filter), it is expected
that the driver will detect the case where the filter already exists, and
return -EEXIST. This is used by calling code such as ice_vc_add_mac_addr,
and ice_vsi_add_vlan to avoid incrementing the accounting fields such as
vsi->num_vlan or vf->num_mac.
This logic works correctly for the case where only a single VSI has added a
given switch filter.
When a second VSI adds the same switch filter, the driver converts the
existing filter from an ICE_FWD_TO_VSI filter into an ICE_FWD_TO_VSI_LIST
filter. This saves switch resources, by ensuring that multiple VSIs can
re-use the same filter.
The ice_add_update_vsi_list() function is responsible for doing this
conversion. When first converting a filter from the FWD_TO_VSI into
FWD_TO_VSI_LIST, it checks if the VSI being added is the same as the
existing rule's VSI. In such a case it returns -EEXIST.
However, when the switch rule has already been converted to a
FWD_TO_VSI_LIST, the logic is different. Adding a new VSI in this case just
requires extending the VSI list entry. The logic for checking if the rule
already exists in this case returns 0 instead of -EEXIST.
This breaks the accounting logic mentioned above, so the counters for how
many MAC and VLAN filters exist for a given VF or VSI no longer accurately
reflect the actual count. This breaks other code which relies on these
counts.
In typical usage this primarily affects such filters generally shared by
multiple VSIs such as VLAN 0, or broadcast and multicast MAC addresses.
Fix this by correctly reporting -EEXIST in the case of adding the same VSI
to a switch rule already converted to ICE_FWD_TO_VSI_LIST.

After vsi setup refactor commit 6624e780a577 ("ice: split ice_vsi_setup

directing LLDP packets to vsi is moved from ice_vsi_release to
ice_vsi_decfg function. ice_vsi_decfg is used in more cases than just in
vsi_release resulting in unnecessary removal of rx lldp packets handling
switch rule. This leads to lldp packets being dropped after a change number
of channels via ethtool.
This patch moves ice_cfg_sw_lldp function that removes rx lldp sw rule back
to ice_vsi_release function.

The current implementation of pmbus_show_boolean assumes that all devices
support write-back operation of status register to clear pending warnings
or faults. Since clearing individual bits in the status registers was only
introduced in PMBus specification 1.2, this operation may not be supported
by some older devices. This can result in an error while reading boolean
attributes such as temp1_max_alarm.
Fetch PMBus revision supported by the device and modify pmbus_show_boolean
so that it only tries to clear individual status bits if the device is
compliant with PMBus specs >= 1.2. Otherwise clear all fault indicators
on the current page after a fault status was reported.

The panasonic laptop code in various places uses the SINF array with index
values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF array
is big enough.
Not all panasonic laptops have this many SINF array entries, for example
the Toughbook CF-18 model only has 10 SINF array entries. So it only
supports the AC+DC brightness entries and mute.
Check that the SINF array has a minimum size which covers all AC+DC
brightness entries and refuse to load if the SINF array is smaller.
For higher SINF indexes hide the sysfs attributes when the SINF array
does not contain an entry for that attribute, avoiding show()/store()
accessing the array out of bounds and add bounds checking to the probe()
and resume() code accessing these.

Convert all drivers below sound/soc to use .remove(), with the eventual
goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just

Fast symlink can be used if the on-disk symlink data is stored
in the same block as the on-disk inode, so we don’t need to trigger
another I/O for symlink data. However, currently fs correction could be
reported _incorrectly_ if inode xattrs are too large.
In fact, these should be valid images although they cannot be handled as
fast symlinks.

The fcntl's F_SETOWN command sets the process that handle SIGIO/SIGURG
for the related file descriptor. Before this change, the
file_set_fowner LSM hook was always called, ignoring the VFS logic which
may not actually change the process that handles SIGIO (e.g. TUN, TTY,
dnotify), nor update the related UID/EUID.
Moreover, because security_file_set_fowner() was called without lock
(e.g. f_owner.lock), concurrent F_SETOWN commands could result to a race
condition and inconsistent LSM states (e.g. SELinux's fown_sid) compared
to struct fown_struct's UID/EUID.
This change makes sure the LSM states are always in sync with the VFS
state by moving the security_file_set_fowner() call close to the
UID/EUID updates and using the same f_owner.lock .
Rename f_modown() to __f_setown() to simplify code.

Nothing ever calls mt8365_dai_load_dmic_iirc_coeff_table() so the compiler
warns about an unused static function. While it seems likely that something
should be calling the function I don't know what and this is breaking
-Werror builds like allmodconfig so let's just remove it. It can be added
again along with the user.

The mt8365 driver uses bits.h to define bitfields but BIT() uses unsigned

The submit queue polling threads are userland threads that just never
exit to the userland. When creating the thread with IORING_SETUP_SQ_AFF,
the affinity of the poller thread is set to the cpu specified in
sq_thread_cpu. However, this CPU can be outside of the cpuset defined
by the cgroup cpuset controller. This violates the rules defined by the
cpuset controller and is a potential issue for realtime applications.
In b7ed6d8ffd6 we fixed the default affinity of the poller thread, in
case no explicit pinning is required by inheriting the one of the
creating task. In case of explicit pinning, the check is more
complicated, as also a cpu outside of the parent cpumask is allowed.
We implemented this by using cpuset_cpus_allowed (that has support for
cgroup cpusets) and testing if the requested cpu is in the set.

The top of the 2 level CD table is (at most) 1024 entries big, and two
high order allocations are required. One of __le64 which is programmed
into the HW (8k) and one of struct arm_smmu_l1_ctx_desc which holds the
CPU pointer (16k).
There are two copies of the l2ptr_dma, one is stored in the struct
arm_smmu_l1_ctx_desc, and another is encoded in the __le64 for the HW to
use. Instead of storing two copies just decode the value from the __le64.

These values can be computed from the other values already stored in the

This moves all the logic to calculate the two registers into one function
from three and saves an unimportant 16 bytes from the arm_smmu_device.
