When the I2C controllers are running in DMA mode, it is the DMA engine
that performs the memory accesses rather than the I2C controller. Pass
the DMA engine's struct device pointer to the DMA API to make sure the
correct DMA operations are used.
This fixes an issue where the DMA engine's SMMU stream ID needs to be
misleadingly set for the I2C controllers in device tree.

Platform drivers .remove callbacks are not supposed to fail and report
errors. Such errors are indeed ignored by the core platform drivers
and the driver unbind process is anyway completed.
The SCMI core platform driver as it is now, instead, bails out reporting
an error in case of an explicit unbind request.
Fix the removal path by adding proper device links between the core SCMI
device and the SCMI protocol devices so that a full SCMI stack unbind is
triggered when the core driver is removed. The remove process does not
bail out anymore on the anomalous conditions triggered by an explicit
unbind but the user is still warned.

There's a small window where a LOCK sent during a delegation return can
race with another OPEN on client, but the open stateid has not yet been
updated. In this case, the client doesn't handle the OLD_STATEID error
from the server and will lose this lock, emitting:
"NFS: nfs4_handle_delegation_recall_error: unhandled error -10024".
Fix this by sending the task through the nfs4 error handling in
nfs4_lock_done() when we may have to reconcile our stateid with what the
server believes it to be. For this case, the result is a retry of the
LOCK operation with the updated stateid.

Some x86/ACPI laptops with MIPI cameras have a LATT2021 ACPI device
in the _DEP dependency list of the ACPI devices for the camera-sensors
(which have flags.honor_deps set).
The _DDN for the LATT2021 device is "Lattice FW Update Client Driver",
suggesting that this is used for firmware updates of something. There
is no Linux driver for this and if Linux gets support for updates it
will likely be in userspace through fwupd.
For now add the LATT2021 HID to acpi_ignore_dep_ids[] so that
acpi_dev_ready_for_enumeration() will return true once the other _DEP
dependencies are met.

[ Upstream commit ca08a1725d0d78efca8d2dbdbce5ea70355da0f2 ]
When using a device based on DCN32/321,
we have an issue where a second
4k@60Hz display does not light up,
and the system becomes unresponsive
for a few minutes. In the debug process,
it was possible to see a hang
in the function dcn20_post_unlock_program_front_end
in this part:
for (j = 0; j < TIMEOUT_FOR_PIPE_ENABLE_MS*1000
&& hubp->funcs->hubp_is_flip_pending(hubp); j++)
mdelay(1);
}
The hubp_is_flip_pending always returns positive
for waiting pending flips which is a symptom of
pipe hang. Additionally, the dmesg log shows
this message after a few minutes:
BUG: soft lockup - CPU#4 stuck for 26s!
...
[ +0.000003] dcn20_post_unlock_program_front_end+0x112/0x340 [amdgpu]

[ +0.000154] dc_commit_state+0xe2/0xf0 [amdgpu]
This confirmed the hypothesis that we had a pipe
hanging somewhere. Next, after checking the
ftrace entries, we have the below weird
sequence:
[..]
2) | dcn10_lock_all_pipes [amdgpu]() {
2) 0.120 us | optc1_is_tg_enabled [amdgpu]();

[..]
We are not expected to read from dmub register
so many times and for so long. From the trace log,
it was possible to identify that the function
dcn20_pipe_control_lock was triggering the dmub
operation when it was unnecessary and causing
the hang issue. This commit drops the unnecessary
dmub code and, consequently, fixes the second display not
lighting up the issue.

probe, the regmap will bet set to cache only mode, then a read error
like below would be triggered when trying to read the initial power

commit a7605426666196c5a460dd3de6f8dac1d3c21f00 upstream.
The current behavior of memory failure is to truncate the page cache
regardless of dirty or clean. If the page is dirty the later access
will get the obsolete data from disk without any notification to the
users. This may cause silent data loss. It is even worse for shmem
since shmem is in-memory filesystem, truncating page cache means
discarding data blocks. The later read would return all zero.
The right approach is to keep the corrupted page in page cache, any
later access would return error for syscalls or SIGBUS for page fault,
until the file is truncated, hole punched or removed. The regular
storage backed filesystems would be more complicated so this patch is
focused on shmem. This also unblock the support for soft offlining
shmem THP.

Memory failure will report failure if the page still has extra pinned
refcount other than from hwpoison after the handler is done. Actually
the check is not necessary for all handlers, so move the check into

There may be expected extra pin for some cases, for example, when the
page is dirty and in swapcache.

commit ef2cb4f0ce479f77607b04c4b0414bf32f863ee8 upstream.
In case the controller detected an error, the code took the chance to move
all the queued (submitted) descriptors to the active (issued) list. This
was wrong as if there were any descriptors in the submitted list they were
moved to the issued list without actually issuing them to the controller,
thus a completion could be raised without even fireing the descriptor.

commit 03ed9ba357cc78116164b90b87f45eacab60b561 upstream.
The tasklet (atc_advance_work()) did not held the channel lock when
retrieving the first active descriptor, causing concurrency problems if
issue_pending() was called in between. If issue_pending() was called
exactly after the lock was released in the tasklet (atc_advance_work()),
atc_chain_complete() could complete a descriptor for which the controller
has not yet raised an interrupt.

commit c6babed879fbe82796a601bf097649e07382db46 upstream.
atc_complete_all() had concurrency bugs, thus remove it:
1/ atc_complete_all() in its entirety was buggy, as when the atchan->queue
list (the one that contains descriptors that are not yet issued to the
hardware) contained descriptors, it fired just the first from the
atchan->queue, but moved all the desc from atchan->queue to
atchan->active_list and considered them all as fired. This could result in
calling the completion of a descriptor that was not yet issued to the
hardware.
2/ when in tasklet at atc_advance_work() time, atchan->active_list was
queried without holding the lock of the chan. This can result in
atchan->active_list concurrency problems between the tasklet and
issue_pending().

commit fcd37565efdaffeac179d0f0ce980ac79bfdf569 upstream.
Multiple calls to atc_issue_pending() could result in a premature
completion of a descriptor from the atchan->active list, as the method
always completed the first active descriptor from the list. Instead,
issue_pending() should just take the first transaction descriptor from the
pending queue, move it to active_list and start the transfer.

commit 7176a6a8982d311e50a7c1168868d26e65bbba19 upstream.
tx_submit is supposed to push the current transaction descriptor to a
pending queue, waiting for issue_pending() to be called. issue_pending()
must start the transfer, not tx_submit(), thus remove atc_dostart() from
atc_tx_submit(). Clients of at_xdmac that assume that tx_submit() starts
the transfer must be updated and call dma_async_issue_pending() if they
miss to call it.
The vdbg print was moved to after the lock is released. It is desirable to
do the prints without the lock held if possible, and because the if
statement disappears there's no reason why to do the print while holding
the lock.

commit 93b0d9178743a68723babe8448981f658aebc58e upstream.
mfill_atomic_install_pte() checks page->mapping to detect whether one page
is used in the page cache. However as pointed out by Matthew, the page
can logically be a tail page rather than always the head in the case of
uffd minor mode with UFFDIO_CONTINUE. It means we could wrongly install
one pte with shmem thp tail page assuming it's an anonymous page.
It's not that clear even for anonymous page, since normally anonymous
pages also have page->mapping being setup with the anon vma. It's safe
here only because the only such caller to mfill_atomic_install_pte() is
always passing in a newly allocated page (mcopy_atomic_pte()), whose
page->mapping is not yet setup. However that's not extremely obvious
either.
For either of above, use page_mapping() instead.
