There are a lot of small msm fixes, and a slightly larger set of vc4

hardware differences from earlier ones, and problems in the page flip
and modeset code which assumed earlier hw, so I thought it would be
okay to keep them in.

- Adjust GTT size logic
- eDP fix for RMB
- DCN 3.15 fix
- DP training fix
- Color encoding fix for DCN2+
sun4i:
- multiple suspend fixes
vc4:
- rework driver split for rpi4, fixes mulitple crashers.
panel:
- quirk for Aya Neo Next
i915:
- Revert low voltage SKU check removal to fix display issues
- Apply PLL DCO fraction workaround for ADL-S
- Don't show engine classes not present in client fdinfo
msm:
- Workaround for parade DSI bridge power sequencing
- Fix for multi-planar YUV format offsets
- Limiting WB modes to max sspp linewidth
- Fixing the supported rotations to add 180 back for IGT
- Fix to handle pm_runtime_get_sync() errors to avoid unclocked
access in the bind() path for dpu driver
- Fix the irq_free() without request issue which was a being hit

USB: gadget: Fix double-free bug in raw_gadget driver
Re-reading a recently merged fix to the raw_gadget driver showed that
it inadvertently introduced a double-free bug in a failure pathway.
If raw_ioctl_init() encounters an error after the driver ID number has
been allocated, it deallocates the ID number before returning. But
when dev_free() runs later on, it will then try to deallocate the ID
number a second time.
Closely related to this issue is another error in the recent fix: The
ID number is stored in the raw_dev structure before the code checks to
see whether the structure has already been initialized, in which case
the new ID number would overwrite the earlier value.
The solution to both bugs is to keep the new ID number in a local
variable, and store it in the raw_dev structure only after the check
for prior initialization. No errors can occur after that point, so
the double-free will never happen.

dm mirror log: clear log bits up to BITS_PER_LONG boundary
Commit
4b568c5f4a94 ("dm mirror log: round up region bitmap size to
BITS_PER_LONG") introduced a regression on 64-bit architectures in the
lvm testsuite tests: lvcreate-mirror, mirror-names and vgsplit-operation.
If the device is shrunk, we need to clear log bits beyond the end of the
device. The code clears bits up to a 32-bit boundary and then calculates
lc->sync_count by summing set bits up to a 64-bit boundary (the commit
changed that; previously, this boundary was 32-bit too). So, it was using
some non-zeroed bits in the calculation and this caused misbehavior.
Fix this regression by clearing bits up to BITS_PER_LONG boundary.

dm: fix BLK_STS_DM_REQUEUE handling when dm_io represents split bio
Commit
c338ba1f10d6 ("dm: improve bio splitting and associated IO
accounting") removed using cloned bio when dm io splitting is needed.
Using bio_trim()+bio_inc_remaining() rather than bio_split()+bio_chain()
causes multiple dm_io instances to share the same original bio, and it
works fine if IOs are completed successfully.
But a regression was caused for the case when BLK_STS_DM_REQUEUE is
returned from any one of DM's cloned bios (whose dm_io share the same
orig_bio). In this BLK_STS_DM_REQUEUE case only the mapped subset of
the original bio for the current exact dm_io needs to be re-submitted.
However, since the original bio is shared among all dm_io instances,
the ->orig_bio actually only represents the last dm_io instance, so
requeue can't work as expected. Also when more than one dm_io is
requeued, the same original bio is requeued from all dm_io's
completion handler, then race is caused.
Fix this issue by still allocating one clone bio for completing io
only, then io accounting can rely on ->orig_bio being unmodified. This
is needed because the dm_io's sector_offset and sectors members are
recorded relative to an unmodified ->orig_bio.
In the future, we can go back to using bio_trim()+bio_inc_remaining()
for dm's io splitting but then delay needing a bio clone only when
handling BLK_STS_DM_REQUEUE, but that approach is a bit complicated
(so it needs a development cycle):
1) bio clone needs to be done in task context
2) a block interface for unwinding bio is required

MAINTAINERS: Reorganize KVM/x86 maintainership
For the last few years I have been the sole maintainer of KVM, albeit
getting serious help from all the people who have reviewed hundreds of
patches. The volume of KVM x86 alone has gotten to the point where one
maintainer is not enough; especially if that maintainer is not doing it
full time and if they want to keep up with the evolution of ARM64 and
RISC-V at both the architecture and the hypervisor level.
So, this patch is the first step in restoring double maintainership
or even transitioning to the submaintainer model of other architectures.
The changes here were mostly proposed by Sean offlist and they are twofold:
- revisiting the set of KVM x86 reviewers. It's important to have an
an accurate list of people that are actively reviewing patches ("R"),
as well as people that are able to act on bug reports ("M"). Otherwise,
voids to be filled are not easily visible. The proposal is to split
KVM on Hyper-V, which is where Vitaly has been the main contributor
for quite some time now; likewise for KVM paravirt support, which
has been the main interest of Wanpeng and to which Vitaly has also
contributed (e.g., for async page faults). Jim and Joerg have not been
particularly active (though Joerg has worked on guest support for AMD
SEV); knowing them a bit, I can't imagine they would object to their
removal or even be surprised, but please speak up if you do.
- promoting Sean to maintainer for KVM x86 host support. While for
now this changes little, let's treat it as a harbinger for future
changes. The plan is that I would keep the final integration testing
for quite some time, and probably focus more on -rc work. This will
give me more time to clean up my ad hoc setup and moving towards a
more public CI, with Sean focusing instead on next-release patches,
and the testing up to where kvm-unit-tests and selftests pass. In
order to facilitate collaboration between Sean and myself, we'll
also formalize a bit more the various branches of kvm.git.
Nothing is going to change with respect to handling pull requests to Linus
and from other architectures, as well as maintainance of the generic code
(which I expect and hope to be more important as architectures try to
share more code) and documentation. However, it's not a coincidence
that my entry is now the last for x86, ready to be demoted to reviewer
if/when the right time comes.

filemap: Fix serialization adding transparent huge pages to page cache
Commit
f6ce77793d9a ("mm/readahead: Add large folio readahead")
introduced support for using large folios for filebacked pages if the
filesystem supports it.
page_cache_ra_order() was introduced to allocate and add these large
folios to the page cache. However adding pages to the page cache should
be serialized against truncation and hole punching by taking
invalidate_lock. Not doing so can lead to data races resulting in stale
data getting added to the page cache and marked up-to-date. See commit
57f0fb86ef1d ("mm: Protect operations adding pages to page cache with
invalidate_lock") for more details.
This issue was found by inspection but a testcase revealed it was
possible to observe in practice on XFS. Fix this by taking
invalidate_lock in page_cache_ra_order(), to mirror what is done for the
non-thp case in page_cache_ra_unbounded().

s390/pai: Fix multiple concurrent event installation
Two different events such as pai_crypto/KM_AES_128/ and
pai_crypto/KM_AES_192/ can be installed multiple times on the same CPU
and the events are executed concurrently:
# perf stat -e pai_crypto/KM_AES_128/ -C0 -a -- sleep 5 &
# sleep 2
# perf stat -e pai_crypto/KM_AES_192/ -C0 -a -- true
This results in the first event being installed two times with two seconds
delay. The kernel does install the second event after the first
event has been deleted and re-added, as can be seen in the traces:
13:48:47.600350 paicrypt_start event 0x1007 (event KM_AES_128)
13:48:49.599359 paicrypt_stop event 0x1007 (event KM_AES_128)
13:48:49.599198 paicrypt_start event 0x1007
13:48:49.599199 paicrypt_start event 0x1008
13:48:49.599921 paicrypt_event_destroy event 0x1008
13:48:52.601507 paicrypt_event_destroy event 0x1007
This is caused by functions event_sched_in() and event_sched_out() which
call the PMU's add() and start() functions on schedule_in and the PMU's
stop() and del() functions on schedule_out. This is correct for events
attached to processes. The pai_crypto events are system-wide events
and not attached to processes.
Since the kernel common code can not be changed easily, fix this issue
and do not reset the event count value to zero each time the event is
added and started. Instead use a flag and zero the event count value
only when called immediately after the event has been initialized.
Therefore only the first invocation of the the event's add() function
initializes the event count value to zero. The following invocations
of the event's add() function leave the current event count value
untouched.

xen/gntdev: Avoid blocking in unmap_grant_pages()
unmap_grant_pages() currently waits for the pages to no longer be used.
In https://github.com/QubesOS/qubes-issues/issues/7481, this lead to a
deadlock against i915: i915 was waiting for gntdev's MMU notifier to
finish, while gntdev was waiting for i915 to free its pages. I also
believe this is responsible for various deadlocks I have experienced in
the past.
Avoid these problems by making unmap_grant_pages async. This requires
making it return void, as any errors will not be available when the
function returns. Fortunately, the only use of the return value is a
WARN_ON(), which can be replaced by a WARN_ON when the error is
detected. Additionally, a failed call will not prevent further calls
from being made, but this is harmless.
Because unmap_grant_pages is now async, the grant handle will be sent to
INVALID_GRANT_HANDLE too late to prevent multiple unmaps of the same
handle. Instead, a separate bool array is allocated for this purpose.
This wastes memory, but stuffing this information in padding bytes is
too fragile. Furthermore, it is necessary to grab a reference to the
map before making the asynchronous call, and release the reference when
the call returns.
It is also necessary to guard against reentrancy in gntdev_map_put(),
and to handle the case where userspace tries to map a mapping whose
contents have not all been freed yet.

net: openvswitch: fix parsing of nw_proto for IPv6 fragments
When a packet enters the OVS datapath and does not match any existing
flows installed in the kernel flow cache, the packet will be sent to
userspace to be parsed, and a new flow will be created. The kernel and
OVS rely on each other to parse packet fields in the same way so that
packets will be handled properly.
As per the design document linked below, OVS expects all later IPv6
fragments to have nw_proto=44 in the flow key, so they can be correctly
matched on OpenFlow rules. OpenFlow controllers create pipelines based
on this design.
This behavior was changed by the commit in the Fixes tag so that
nw_proto equals the next_header field of the last extension header.
However, there is no counterpart for this change in OVS userspace,
meaning that this field is parsed differently between OVS and the
kernel. This is a problem because OVS creates actions based on what is
parsed in userspace, but the kernel-provided flow key is used as a match
criteria, as described in Documentation/networking/openvswitch.rst. This
leads to issues such as packets incorrectly matching on a flow and thus
the wrong list of actions being applied to the packet. Such changes in
packet parsing cannot be implemented without breaking the userspace.
The offending commit is partially reverted to restore the expected
behavior.
The change technically made sense and there is a good reason that it was
implemented, but it does not comply with the original design of OVS.
If in the future someone wants to implement such a change, then it must
be user-configurable and disabled by default to preserve backwards
compatibility with existing OVS versions.

sock: redo the psock vs ULP protection check
Commit
df7c8df97eba ("sock: Introduce sk->sk_prot->psock_update_sk_prot()")
has moved the inet_csk_has_ulp(sk) check from sk_psock_init() to
the new tcp_bpf_update_proto() function. I'm guessing that this
was done to allow creating psocks for non-inet sockets.
Unfortunately the destruction path for psock includes the ULP
unwind, so we need to fail the sk_psock_init() itself.
Otherwise if ULP is already present we'll notice that later,
and call tcp_update_ulp() with the sk_proto of the ULP
itself, which will most likely result in the ULP looping
its callbacks.

This happens because virtnet_freeze() frees the receive_queue
completely (including struct xdp_rxq_info) but does not call
xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets up the
receive_queue again but does not call xdp_rxq_info_reg().
Actually, parts of virtnet_freeze_down() and virtnet_restore_up()
are almost identical to virtnet_close() and virtnet_open(): only
the calls to xdp_rxq_info_(un)reg() are missing. This means that
we can fix this easily and avoid such problems in the future by
just calling virtnet_close()/open() from the freeze/restore handlers.
Aside from adding the missing xdp_rxq_info calls the only difference
is that the refill work is only cancelled if netif_running(). However,
this should not make any functional difference since the refill work
should only be active if the network interface is actually up.

igb: Make DMA faster when CPU is active on the PCIe link
Intel I210 on some Intel Alder Lake platforms can only achieve ~750Mbps
Tx speed via iperf. The RR2DCDELAY shows around 0x2xxx DMA delay, which
will be significantly lower when 1) ASPM is disabled or 2) SoC package
c-state stays above PC3. When the RR2DCDELAY is around 0x1xxx the Tx
speed can reach to ~950Mbps.
According to the I210 datasheet "8.26.1 PCIe Misc. Register - PCIEMISC",
"DMA Idle Indication" doesn't seem to tie to DMA coalesce anymore, so
set it to 1b for "DMA is considered idle when there is no Rx or Tx AND
when there are no TLPs indicating that CPU is active detected on the
PCIe link (such as the host executes CSR or Configuration register read
or write operation)" and performing Tx should also fall under "active
CPU on PCIe link" case.

drm/amd: Revert "drm/amd/display: keep eDP Vdd on when eDP stream is already enabled"
A variety of Lenovo machines with Rembrandt APUs and OLED panels have
stopped showing the display at login. This behavior clears up after
leaving it idle and moving the mouse or touching keyboard.
It was bisected to be caused by commit
e1d5994a31b0 ("drm/amd/display:
keep eDP Vdd on when eDP stream is already enabled"). Revert this commit
to fix the issue.

drm/amdgpu: Adjust logic around GTT size (v3)
Certain GL unit tests for large textures can cause problems
with the OOM killer since there is no way to link this memory
to a process. This was originally mitigated (but not necessarily
eliminated) by limiting the GTT size. The problem is this limit
is often too low for many modern games so just make the limit 1/2
of system memory. The OOM accounting needs to be addressed, but
we shouldn't prevent common 3D applications from being usable
just to potentially mitigate that corner case.
Set default GTT size to max(3G, 1/2 of system ram) by default.
v2: drop previous logic and default to 3/4 of ram
v3: default to half of ram to align with ttm
v4: fix spelling in comment (Kent)

hinic: Replace memcpy() with direct assignment
Under CONFIG_FORTIFY_SOURCE=y and CONFIG_UBSAN_BOUNDS=y, Clang is bugged
here for calculating the size of the destination buffer (0x10 instead of
0x14). This copy is a fixed size (sizeof(struct fw_section_info_st)), with
the source and dest being struct fw_section_info_st, so the memcpy should
be safe, assuming the index is within bounds, which is UBSAN_BOUNDS's
responsibility to figure out.
Avoid the whole thing and just do a direct assignment. This results in
no change to the executable code.
[This is a duplicate of commit
2c0ab32b73cf ("hinic: Replace memcpy()
with direct assignment") which was applied to net-next.]
