Add a tiling atttribute to the modifier descriptor, which let's us
get the tiling without listing the modifiers twice.
v1-v2: Unchanged.
v3:
- Initialize .tiling to I915_TILING_NONE explicitly (Ville)
- Move from previous patch lookup_modifier() to here, where it's first
used.

Move the function retrieving the format override information for a given
format/modifier to intel_fb.c. We can store a pointer to the format list
in each modifier's descriptor instead of the corresponding switch/case
logic, avoiding the listing of the modifiers twice.
v1: Unchanged.
v2: Handle invalid modifiers in intel_fb_get_format_info() passed from
userspace. (CI/igt_kms_addfb_basic/addfb25-bad-modifier)
v3: Move lookup_modifier() to the next patch, where it's first used.

Add a table describing all the framebuffer modifiers used by i915 at one
place. This has the benefit of deduplicating the listing of supported
modifiers for each platform and checking the support of these modifiers
on a given plane. This also simplifies in a similar way getting some
attribute for a modifier, for instance checking if the modifier is a
CCS modifier type.
While at it drop the cursor plane filtering from skl_plane_has_rc_ccs(),
as the cursor plane is registered with DRM core elsewhere.
v1: Unchanged.
v2:
- Keep the plane caps calculation in the plane code and pass an enum
with these caps to intel_fb_get_modifiers(). (Ville)
- Get the modifiers calling intel_fb_get_modifiers() in i9xx_plane.c as
well.
v3:
- s/.id/.modifier/ (Ville)
- Keep modifier_desc vs. plane_cap filter conditions consistent. (Ville)
- Drop redundant cursor plane check from skl_plane_has_rc_ccs(). (Ville)
- Use from, until display version fields in modifier_desc instead of a mask. (Jani)
- Unexport struct intel_modifier_desc, separate its decl and init. (Jani)
- Remove enum pipe, plane_id forward decls from intel_fb.h, which are
not needed after v2.
v4:
- Reuse IS_DISPLAY_VER() instead of open-coding it. (Jani)
- Preserve the current modifier order exposed to user space. (Ville)
v5: Use }, { on one line to seperate the descriptor array elements. (Jani)

Another change to the API io-wq worker limitation API added in 5.15,
apply the limit to all prior users that already registered a tctx. It
may be confusing as it's now, in particular the change covers the
following 2 cases:
TASK1 | TASK2
_________________________________________________
ring = create() |
| limit_iowq_workers()
*not limited* |
TASK1 | TASK2
_________________________________________________
ring = create() |
| issue_requests()
limit_iowq_workers() |
| *not limited*
A note on locking, it's safe to traverse ->tctx_list as we hold
->uring_lock, but do that after dropping sqd->lock to avoid possible
problems. It's also safe to access tctx->io_wq there because tasks
kill it only after removing themselves from tctx_list, see
io_uring_cancel_generic() -> io_uring_clean_tctx()

The enetc driver does not implement .ndo_change_mtu, instead it
configures the MAC register field PTC{Traffic Class}MSDUR[MAXSDU]
statically to a large value during probe time.
The driver used to configure only the max SDU for traffic class 0, and
that was fine while the driver could only use traffic class 0. But with
the introduction of mqprio, sending a large frame into any other TC than
0 is broken.
This patch fixes that by replicating per traffic class the static
configuration done in enetc_configure_port_mac().

The 1/10GbaseT modes were set up for cards with SFP+ cages in
3497ed8c852a5 ("sfc: report supported link speeds on SFP connections").
10GbaseT was likely used since no 10G fibre mode existed.
The missing fibre modes for 1/10G were added to ethtool.h in 5711a9822144
("net: ethtool: add support for 1000BaseX and missing 10G link modes")
shortly thereafter.
The user guide available at https://support-nic.xilinx.com/wp/drivers
lists support for the following cable and transceiver types in section 2.9:
- QSFP28 100G Direct Attach Cables
- QSFP28 100G SR Optical Transceivers (with SR4 modules listed)
- SFP28 25G Direct Attach Cables
- SFP28 25G SR Optical Transceivers
- QSFP+ 40G Direct Attach Cables
- QSFP+ 40G Active Optical Cables
- QSFP+ 40G SR4 Optical Transceivers
- QSFP+ to SFP+ Breakout Direct Attach Cables
- QSFP+ to SFP+ Breakout Active Optical Cables
- SFP+ 10G Direct Attach Cables
- SFP+ 10G SR Optical Transceivers
- SFP+ 10G LR Optical Transceivers
- SFP 1000BASE‐T Transceivers
- 1G Optical Transceivers
(From user guide issue 28. Issue 16 which also includes older cards like
SFN5xxx/SFN6xxx has matching lists for 1/10/40G transceiver types.)
Regarding SFP+ 10GBASE‐T transceivers the latest guide says:
"Solarflare adapters do not support 10GBASE‐T transceiver modules."
Tested using SFN5122F-R7 (with 2 SFP+ ports). Supported link modes do not change
depending on module used (tested with 1000BASE-T, 1000BASE-BX10, 10GBASE-LR).

This reverts commit 05734ca2a8f76c9eb3890b3c9dfc3467f03105c1.
It's not graceful, instead it leads to boot time warning splats in the
case it is supposed to handle gracefully. Apparently the BIOS/GOP
enabling the port we end up skipping leads to state readout
problems. Back to the drawing board.

The mxsfb->crtc.funcs may already be NULL when unloading the driver,
in which case calling mxsfb_irq_disable() via drm_irq_uninstall() from

valid, just use that to clear and mask the IRQ.

Syzkaller reports a null pointer dereference in fuse_test_super() that is
caused by sb->s_fs_info being NULL.
This is due to the fact that fuse_fill_super() is initializing s_fs_info,
which is too late, it's already on the fs_supers list. The initialization
needs to be done in sget_fc() with the sb_lock held.
Move allocation of fuse_mount and fuse_conn from fuse_fill_super() into
fuse_get_tree().
After this ->kill_sb() will always be called with non-NULL ->s_fs_info,
hence fuse_mount_destroy() can drop the test for non-NULL "fm".

1. call fuse_mount_destroy() for open coded variants
2. before deactivate_locked_super() don't need fuse_mount destruction since
that will now be done (if ->s_fs_info is not cleared)
3. rearrange fuse_mount setup in fuse_get_tree_submount() so that the
regular pattern can be used

The ->put_super callback is called from generic_shutdown_super() in case of
a fully initialized sb. This is called from kill_***_super(), which is
called from ->kill_sb instances.
Fuse uses ->put_super to destroy the fs specific fuse_mount and drop the
reference to the fuse_conn, while it does the same on each error case
during sb setup.
This patch moves the destruction from fuse_put_super() to
fuse_mount_destroy(), called at the end of all ->kill_sb instances. A
follup patch will clean up the error paths.

Checking "fm" works because currently sb->s_fs_info is cleared on error
paths; however, sb->s_root is what generic_shutdown_super() checks to
determine whether the sb was fully initialized or not.
This change will allow cleanup of sb setup error paths.

Since commit c300ab9f08df ("KVM: x86: Replace late check_nested_events() hack with
more precise fix") there is no longer the certainty that check_nested_events()
tries to inject an external interrupt vmexit to L1 on every call to vcpu_enter_guest.
Therefore, even in that case we need to set KVM_REQ_EVENT. This ensures
that inject_pending_event() is called, and from there kvm_check_nested_events().

The kvm_x86_sync_pir_to_irr callback can sometimes set KVM_REQ_EVENT.
If that happens exactly at the time that an exit is handled as
EXIT_FASTPATH_REENTER_GUEST, vcpu_enter_guest will go incorrectly
through the loop that calls kvm_x86_run, instead of processing
the request promptly.

There's a mistake in commit 2be7828c9fefc ("get rid of autofs_getpath()")
that affects kernels from v5.13.0, basically missed because of me not
fully testing the change for Al.
The problem is that the hash calculation for the wait name qstr hasn't
been updated to account for the change to use dentry_path_raw(). This
prevents the correct matching an existing wait resulting in multiple
notifications being sent to the daemon for the same mount which must
not occur.
The problem wasn't discovered earlier because it only occurs when
multiple processes trigger a request for the same mount concurrently
so it only shows up in more aggressive testing.

Current Work Queue Entry (WQE) checksum (csum) flags in the ethernet
segment (eseg) in case of IPsec crypto offload datapath are not aligned
with PRM/HW expectations.
Currently the driver always sets the l3_inner_csum flag in case of IPsec
because of the wrong usage of skb->encapsulation as indicator for inner
IPsec header since skb->encapsulation is always ON for IPsec packets
since IPsec itself is an encapsulation protocol. The above forced a
failing attempts of calculating csum of non-existing segments (like in
the IP|ESP|TCP packet case which does not have an l3_inner) which led
to lots of packet drops hence the low throughput.
Fix by using xo->inner_ipproto as indicator for inner IPsec header
instead of skb->encapsulation in addition to setting the csum flags
as following:
* Tunnel Mode:
* Pkt: MAC IP ESP IP L4
* CSUM: l3_cs | l3_inner_cs | l4_inner_cs
*
* Transport Mode:
* Pkt: MAC IP ESP L4
* CSUM: l3_cs [ | l4_cs (checksum partial case)]
*
* Tunnel(VXLAN TCP/UDP) over Transport Mode
* Pkt: MAC IP ESP UDP VXLAN IP L4
* CSUM: l3_cs | l3_inner_cs | l4_inner_cs

IPsec crypto offload current Software Parser (SWP) fields settings in
the ethernet segment (eseg) are not aligned with PRM/HW expectations.
Among others in case of IP|ESP|TCP packet, current driver sets the
offsets for inner_l3 and inner_l4 although there is no inner l3/l4
headers relative to ESP header in such packets.
SWP provides the offsets for HW ,so it can be used to find csum fields
to offload the checksum, however these are not necessarily used by HW
and are used as fallback in case HW fails to parse the packet, e.g
when performing IPSec Transport Aware (IP | ESP | TCP) there is no
need to add SW parse on inner packet. So in some cases packets csum
was calculated correctly , whereas in other cases it failed. The later
faced csum errors (caused by wrong packet length calculations) which
led to lots of packet drops hence the low throughput.
Fix by setting the SWP fields as expected in a IP|ESP|TCP packet.
the following describe the expected SWP offsets:
* Tunnel Mode:
* SWP: OutL3 InL3 InL4
* Pkt: MAC IP ESP IP L4
*
* Transport Mode:
* SWP: OutL3 OutL4
* Pkt: MAC IP ESP L4
*
* Tunnel(VXLAN TCP/UDP) over Transport Mode
* SWP: OutL3 InL3 InL4
* Pkt: MAC IP ESP UDP VXLAN IP L4

Both multipath and bonding events are changing the HW LAG state
independently.
Handling one of the features events while the other is already
enabled can cause unwanted behavior, for example handling
bonding event while multipath enabled will disable the lag and
cause multipath to stop working.
Fix it by ignoring bonding event while in multipath and ignoring FIB
events while in bonding mode.
