a6984a3f9a drm/msm/hdmi: drop clock frequency assignment
The only clock which has frequency being set through hpd_freqs is the
"core" aka MDSS_HDMI_CLK clock. It always has the specified frequency,
so we can drop corresponding clk_set_rate() call together with the
hpd_freq infrastructure.

be0e9a3727 clk: sunxi-ng: ccu: add Display Engine 3.3 (DE33) support
The DE33 is a newer version of the Allwinner Display Engine IP block,
found in the H616, H618, H700 and T507 SoCs. DE2 and DE3 are already
supported by the mainline driver.

The DE33 in the H616 has mixer0 and writeback units. The clocks
and resets required are identical to the H3 and H5 respectively, so use
those existing structs for the H616 description.

There are two additional 32-bit registers (at offsets 0x24 and 0x28)
which require clearing and setting respectively to bring up the
hardware. The function of these registers is currently unknown, and the
values are taken from the out-of-tree driver.

Add the required clock description struct and compatible string to the
DE2 driver.

When the binding was originally written, it was assumed that all
ax45mp-caches had the same properties etc. This has turned out to be
incorrect, as the QiLai SoC has a different number of cache-sets.

Add a specific compatible for the RZ/Five for property enforcement and
in case there turns out to be additional differences between these

f446c6311e io_uring/memmap: don't use page_address() on a highmem page
For older/32-bit systems with highmem, don't assume that the pages in
a mapped region are always going to be mapped. If io_region_init_ptr()
finds that the pages are coalescable, also check if the first page is
a HighMem page or not. If it is, fall through to the usual vmap()
mapping rather than attempt to get the unmapped page address.

cef88d1265 drm/xe/vf: Fixup CTB send buffer messages after migration
During post-migration recovery of a VF, it is necessary to update
GGTT references included in messages which are going to be sent
to GuC. GuC will start consuming messages after VF KMD will inform
it about fixups being done; before that, the VF KMD is expected
to update any H2G messages which are already in send buffer but
were not consumed by GuC.

Only a small subset of messages allowed for VFs have GGTT references
in them. This patch adds the functionality to parse the CTB send
ring buffer and shift addresses contained within.

While fixing the CTB content, ct->lock is not taken. This means
the only barrier taken remains GGTT address lock - which is ok,
because only requests with GGTT addresses matter, but it also means
tail changes can happen during the CTB fixups execution (which may
be ignored as any new messages will not have anything to fix).

The GGTT address locking will be introduced in a future series.

v2: removed storing shift as that's now done in VMA nodes patch;
  macros to inlines; warns to asserts; log messages fixes (Michal)
v3: removed inline keywords, enums for offsets in CTB messages,
  less error messages, if return unused then made functs void (Michal)
v4: update the cached head before starting fixups
v5: removed/updated comments, wrapped lines, converted assert into
  error, enums for offsets to separate patch, reused xe_map_rd
v6: define xe_map_*_array() macros, support CTB wrap which divides
  a message, updated comments, moved one function to an earlier patch
v7: renamed few functions, wider use on previously introduced helper,
  separate cases in parsing messges, documented a static funct
v8: Introduced more helpers, fixed coding style mistakes
v9: Move xe_map*() functs to macros, add asserts, add debug print
v10: Errors in place of some asserts, style fixes
v11: Fixed invalid conditionals, added debug-only local pointer
v12: Removed redundant __maybe_unused

e327592cc9 drm/xe/guc: Introduce enum with offsets for context register H2Gs
Some GuC messages are constructed with incrementing dword counter
rather than referencing specific DWORDs, as described in GuC interface
specification.

This change introduces the definitions of DWORD numbers for parameters
which will need to be referenced in a CTB parser to be added in a
following patch. To ensure correctness of these DWORDs, verification
in form of asserts was added to the message construction code.

v2: Renamed enum members, added ones for single context registration,
  modified asserts to check values rather than indexes.
v3: Reordered assert args to take less lines
v4: Added lengths
v5: Renamed MULTI_LRC_MSG_LEN to MULTI_LRC_MSG_MIN_LEN

3e693945b1 drm/xe/vf: Shifting GGTT area post migration
We have only one GGTT for all IOV functions, with each VF having assigned
a range of addresses for its use. After migration, a VF can receive a
different range of addresses than it had initially.

This implements shifting GGTT addresses within drm_mm nodes, so that
VMAs stay valid after migration. This will make the driver use new
addresses when accessing GGTT from the moment the shifting ends.

By taking the ggtt->lock for the period of VMA fixups, this change
also adds constraint on that mutex. Any locks used during the recovery
cannot ever wait for hardware response - because after migration,
the hardware will not do anything until fixups are finished.

v2: Moved some functs to xe_ggtt.c; moved shift computation to just
  after querying; improved documentation; switched some warns to asserts;
  skipping fixups when GGTT shift eq 0; iterating through tiles (Michal)
v3: Updated kerneldocs, removed unused funct, properly allocate
  balloning nodes if non existent
v4: Re-used ballooning functions from VF init, used bool in place of
  standard error codes
v5: Renamed one function
v6: Subject tag change, several kerneldocs updated, some functions
  renamed, some moved, added several asserts, shuffled declarations
  of variables, revealed more detail in high level functions
v7: Fixed typos, added `_locked` suffix to some functs, improved
  readability of asserts, removed unneeded conditional
v8: Moved one function, removed implementation detail from kerneldoc,
  added asserts
v9: Code shuffling without much change, and one param rename
v10: Minor error path change, added printing the shift via debugfs

dd39212b5f drm/xe/vf: Divide GGTT ballooning into allocation and insertion
The balloon nodes, which are used to fill areas of GGTT inaccessible
for a specific VF, were allocated and inserted into GGTT within one
function. To be able to re-use that insertion code during VF
migration recovery, we need to split it.

This patch separates allocation (init/fini functs) from the insertion
of balloons (balloon/deballoon functs). Locks are also moved to ensure
calls from post-migration recovery worker will not cause a deadlock.

v2: Moved declarations to proper header
v3: Rephrased description, introduced "_locked" versions of some
  functs, more lockdep checks, some functions renamed, altered error
  handling, added missing kerneldocs.
v4: Suffixed more functs with `_locked`, moved lockdep asserts,
  fixed finalization in error path, added asserts
v5: Renamed another few functs, used xe_ggtt_node_allocated(),
  moved lockdep back again to avoid null dereference, added
  asserts, improved comments
v6: Changed params of cleanup_ggtt()

8fb7aee055 io_uring: drain based on allocates reqs
Don't rely on CQ sequence numbers for draining, as it has become messy
and needs cq_extra adjustments. Instead, base it on the number of
allocated requests and only allow flushing when all requests are in the
drain list.

As a result, cq_extra is gone, no overhead for its accounting in aux cqe
posting, less bloating as it was inlined before, and it's in general
simpler than trying to track where we should bump it and where it should
be put back like in cases of overflow. Also, it'll likely help with
cleaning and unifying some of the CQ posting helpers.

64b9dfd077 ACPICA: Avoid sequence overread in call to strncmp()
ACPICA commit 8b83a8d88dfec59ea147fad35fc6deea8859c58c

ap_get_table_length() checks if tables are valid by
calling ap_is_valid_header(). The latter then calls
ACPI_VALIDATE_RSDP_SIG(Table->Signature).

ap_is_valid_header() accepts struct acpi_table_header as an argument, so
the signature size is always fixed to 4 bytes.

The problem is when the string comparison is between ACPI-defined table
signature and ACPI_SIG_RSDP. Common ACPI table header specifies the
Signature field to be 4 bytes long[1], with the exception of the RSDP
structure whose signature is 8 bytes long "RSD PTR " (including the
trailing blank character)[2]. Calling strncmp(sig, rsdp_sig, 8) would
then result in a sequence overread[3] as sig would be smaller (4 bytes)
than the specified bound (8 bytes).

As a workaround, pass the bound conditionally based on the size of the
signature being passed.
