We use spatial dither by default for all output bpc (6/8/10). While it
makes some sense for FP16, for ARGB2101010 surfaces it makes little
sense as even if we skip color pipeline to preserve bit accuracy,
spatial dither adds random noise so a few percent pixels are 1 bit off.
This commit chages the 10bpc out dither policy to rounding.
Also, in Polaris/Vega times, policy used to be round for 10bpc out; it
looks like it got inadvertently changed for Navi. Difference is only
detectable with capture cards.

[Why]
OTG inst and pwrseq inst mapping is not align therefore we cannot use
otg_inst as pwrseq inst to get DCIO register.
[How]
1. Pass the correct pwrseq instance to dmub when set abm pipe.
2. LVTMA control index change from panel_inst to pwrseq_inst.

This patch implements partial migration/mapping for gpu/cpu page faults in SVM
according to migration granularity(default 2MB). A svm range may include pages
from both system ram and vram of one gpu now. These chagnes are expected to
improve migration performance and reduce mmu callback and TLB flush workloads.

[WHY]
Many DCN generations only have two HPO link encoders and therefore only
support driving a max of two DP2 PHYs. DP2 MST hubs currently can not
pass 3x display validation as each downstream sink is enumerated as
separate DP2 output.
[HOW]
Count MST hubs once by treating only 1st remote sink in topology as an
encoder.

[why]
When querying DML for a vlevel after pipes have been split or merged the
ODM policy would revert to a default policy, which could cause the query
to use the incorrect ODM status. In this case ODM 2to1 was validated,
but the last DML query would assume no ODM and return the incorrect
vlevel.
[how]
Added ODM check to apply the correct ODM policy before querying DML.

Since 64 bit cmpxchg() is very expensive on 32bit architectures, the
timestamp used by the ring buffer does some interesting tricks to be able
to still have an atomic 64 bit number. It originally just used 60 bits and
broke it up into two 32 bit words where the extra 2 bits were used for
synchronization. But this was not enough for all use cases, and all 64
bits were required.
The 32bit version of the ring buffer timestamp was then broken up into 3
32bit words using the same counter trick. But one update was not done. The
check to see if the read operation was done without interruption only
checked the first two words and not last one (like it had before this
update). Fix it by making sure all three updates happen without
interruption by comparing the initial counter with the last updated
counter.

There's a race where if an event is discarded from the ring buffer and an
interrupt were to happen at that time and insert an event, the time stamp
is still used from the discarded event as an offset. This can screw up the
timings.
If the event is going to be discarded, set the "before_stamp" to zero.
When a new event comes in, it compares the "before_stamp" with the
"write_stamp" and if they are not equal, it will insert an absolute
timestamp. This will prevent the timings from getting out of sync due to
the discarded event.

Reconnect worker currently assumes that the server struct
is alive and only takes reference on the server if it needs
to call smb2_reconnect.
With the new ability to disable channels based on whether the
server has multichannel disabled, this becomes a problem when
we need to disable established channels. While disabling the
channels and deallocating the server, there could be reconnect
work that could not be cancelled (because it started).
This change forces the reconnect worker to unconditionally
take a reference on the server when it runs.
Also, this change now allows smb2_reconnect to know if it was
called by the reconnect worker. Based on this, the cifs_put_tcp_session
can decide whether it can cancel the reconnect work synchronously or not.

This earlier commit was making an assumption that each mod_delayed_work

Arm FF-A fixes for v6.7
A bunch of fixes addressing issues around the notification support that
was added this cycle. They address issue in partition IDs handling in
ffa_notification_info_get(), notifications cleanup path and the size of
the allocation in ffa_partitions_cleanup().
It also adds check for the notification enabled state so that the drivers
registering the callbacks can be rejected if not enabled/supported.
It also moves the partitions setup operation after the notification
initialisation so that the driver has the correct state for notification
enabled/supported before the partitions are initialised/setup.
It also now allows FF-A initialisation to complete successfully even
when the notification initialisation fails as it is an optional support
in the specification. Initial support just allowed it only if the
firmware didn't support notifications.
Finally, it also adds a fix for smatch warning by declaring ffa_bus_type
structure in the header.

Maze reports "tcp option fastopen exists" fails to match on
OpenWrt 22.03.5, r20134-5f15225c1e (5.10.176) router.
"tcp option fastopen exists" translates to:
inet
[ exthdr load tcpopt 1b @ 34 + 0 present => reg 1 ]
[ cmp eq reg 1 0x00000001 ]
.. but existing nft userspace generates a 1-byte compare.
On LSB (x86), "*reg32 = 1" is identical to nft_reg_store8(reg32, 1), but
not on MSB, which will place the 1 last. IOW, on bigendian aches the cmp8
is awalys false.
Make sure we store this in a consistent fashion, so existing userspace
will also work on MSB (bigendian).
Regardless of this patch we can also change nft userspace to generate
'reg32 == 0' and 'reg32 != 0' instead of u8 == 0 // u8 == 1 when
adding 'option x missing/exists' expressions as well.

RISC-V Devicetree fixes for v6.7-rc4
Two fixes, both rather minor. The first fixes some dtbs_check warnings
introduced after an update to the bindings, that returns the
architecture to being clean of dtbs_check issues. The second relocates
a soc-specific property to the appropriate location in $soc.dtsi, and
hopefully avoids the same mistake being copy-pasted into more

The i2c_master_send/recv() functions return negative error codes or
they return "len" on success. So the error handling here can be written
as just normal checks for "if (ret < 0) return ret;". No need to
complicate things.
Btw, in this code the "len" parameter can never be zero, but even if
it were, then I feel like this would still be the best way to write it.

This is because we called riscv_noncoherent_supported() for all the stages
during IOCP probe. riscv_noncoherent_supported() function sets
noncoherent_supported variable to true which has an annotation set to
"__ro_after_init" due to which we were seeing the above splat. Fix this by
probing for IOCP only once in boot stage by having a boolean variable
"done" which will be set to true upon IOCP probe in errata_probe_iocp()
and we bail out early if "done" is set to true.
While at it make return type of errata_probe_iocp() to void as we were
not checking the return value in andes_errata_patch_func().

This fixes two bugs in SCS initialization for secondary CPUs. First,
the SCS was not initialized at all in the spinwait boot path. Second,
the code for the SBI HSM path attempted to initialize the SCS before
enabling the MMU. However, that involves dereferencing the thread
pointer, which requires the MMU to be enabled.
Fix both issues by setting up the SCS in the common secondary entry
path, after enabling the MMU.

This is a backport of a fix that was done in OpenSBI: ec0559eb315b
("lib: sbi_misaligned_ldst: Fix handling of C.SWSP and C.SDSP").
Unlike C.LWSP/C.LDSP, these encodings can be used with the zero
register, so checking that the rs2 field is non-zero is unnecessary.
Additionally, the previous check was incorrect since it was checking
the immediate field of the instruction instead of the rs2 field.

Extensions are getting added quickly and their hwprobe bits will soon
exceed 31 (which pair values accommodate, since they're of type u64).
However, in one tree, where a bunch of extensions got merged prior to
zicboz, zicboz already got pushed to bit 32. Pushing it exposed a
32-bit compilation bug, since unsigned long was used instead of u64.

When MCS external bypass is disabled, MCS returns additional
2 credits(32B) for every packet Tx'ed on LMAC. To account for
these extra credits, NIX_AF_TX_LINKX_NORM_CREDIT.CC_MCS_CNT
needs to be configured as otherwise NIX Tx credits would overflow
and will never be returned to idle state credit count
causing issues with credit control and MTU change.
This patch fixes the same by configuring CC_MCS_CNT at probe
time for MCS enabled SoC's

Dmitry Safonov says:
====================
TCP-AO fixes
Changes from v4:
- Dropped 2 patches on which there's no consensus. They will require
more work TBD if they may made acceptable. Those are:
o "net/tcp: Allow removing current/rnext TCP-AO keys on TCP_LISTEN sockets"
o "net/tcp: Store SNEs + SEQs on ao_info"
Changes from v3:
- Don't restrict adding any keys on TCP-AO connection in VRF, but only
the ones that don't match l3index (David)
Changes from v2:
- rwlocks are problematic in net code (Paolo)
Changed the SNE code to avoid spin/rw locks on RX/TX fastpath by
double-accounting SEQ numbers for TCP-AO enabled connections.
Changes from v1:
- Use tcp_can_repair_sock() helper to limit TCP_AO_REPAIR (Eric)
- Instead of hook to listen() syscall, allow removing current/rnext keys
on TCP_LISTEN (addressing Eric's objection)
- Add sne_lock to protect snd_sne/rcv_sne
- Don't move used_tcp_ao in struct tcp_request_sock (Eric)
I've been working on TCP-AO key-rotation selftests and as a result
exercised some corner-cases that are not usually met in production.
Here are a bunch of semi-related fixes:
- Documentation typo (reported by Markus Elfring)
- Proper alignment for TCP-AO option in TCP header that has MAC length
of non 4 bytes (now a selftest with randomized maclen/algorithm/etc
passes)
- 3 uAPI restricting patches that disallow more things to userspace in
order to prevent it shooting itself in any parts of the body
- SNEs READ_ONCE()/WRITE_ONCE() that went missing by my human factor
- Avoid storing MAC length from SYN header as SYN-ACK will use
rnext_key.maclen (drops an extra check that fails on new selftests)
====================

This extra check doesn't work for a handshake when SYN segment has
(current_key.maclen != rnext_key.maclen). It could be amended to
preserve rnext_key.maclen instead of current_key.maclen, but that
requires a lookup on listen socket.
Originally, this extra maclen check was introduced just because it was
cheap. Drop it and convert tcp_request_sock::maclen into boolean
tcp_request_sock::used_tcp_ao.

If the connection was established, don't allow adding TCP-AO keys that
don't match the peer. Currently, there are checks for ip-address
matching, but L3 index check is missing. Add it to restrict userspace
shooting itself somewhere.
Yet, nothing restricts the CAP_NET_RAW user from trying to shoot
themselves by performing setsockopt(SO_BINDTODEVICE) or
setsockopt(SO_BINDTOIFINDEX) over an established TCP-AO connection.
So, this is just "minimum effort" to potentially save someone's
debugging time, rather than a full restriction on doing weird things.

Listen socket is not an established TCP connection, so
setsockopt(TCP_AO_REPAIR) doesn't have any impact.
Restrict this uAPI for listen sockets.
