Pull cxl fixes from Dan Williams:
"A collection of significant fixes for the CXL subsystem.
The largest change in this set, that bordered on "new development", is
the fix for the fact that the location of the new qos_class attribute
did not match the Documentation. The fix ends up deleting more code
than it added, and it has a new unit test to backstop basic errors in
this interface going forward. So the "red-diff" and unit test saved
the "rip it out and try again" response.
In contrast, the new notification path for firmware reported CXL
errors (CXL CPER notifications) has a locking context bug that can not
be fixed with a red-diff. Given where the release cycle stands, it is
not comfortable to squeeze in that fix in these waning days. So, that
receives the "back it out and try again later" treatment.
There is a regression fix in the code that establishes memory NUMA
nodes for platform CXL regions. That has an ack from x86 folks. There
are a couple more fixups for Linux to understand (reassemble) CXL
regions instantiated by platform firmware. The policy around platforms
that do not match host-physical-address with system-physical-address
(i.e. systems that have an address translation mechanism between the
address range reported in the ACPI CEDT.CFMWS and endpoint decoders)
has been softened to abort driver load rather than teardown the memory
range (can cause system hangs). Lastly, there is a robustness /
regression fix for cases where the driver would previously continue in
the face of error, and a fixup for PCI error notification handling.
Summary:
- Fix NUMA initialization from ACPI CEDT.CFMWS
- Fix region assembly failures due to async init order
- Fix / simplify export of qos_class information
- Fix cxl_acpi initialization vs single-window-init failures
- Fix handling of repeated 'pci_channel_io_frozen' notifications
- Workaround platforms that violate host-physical-address ==
system-physical address assumptions
- Defer CXL CPER notification handling to v6.9"

* tag 'i2c-for-6.8-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
i2c: imx: when being a target, mark the last read as processed
The newly added integrity_recheck() function has another larger stack
allocation, just like its caller integrity_metadata(). When it gets
inlined, the combination of the two exceeds the warning limit for 32-bit
architectures and possibly risks an overflow when this is called from
a deep call chain through a file system:
drivers/md/dm-integrity.c:1767:13: error: stack frame size (1048) exceeds limit (1024) in 'integrity_metadata' [-Werror,-Wframe-larger-than]
1767 | static void integrity_metadata(struct work_struct *w)
Since the caller at this point is done using its checksum buffer,
just reuse the same buffer in the new function to avoid the double
allocation.
[Mikulas: add "noinline" to integrity_recheck and verity_recheck.
These functions are only called on error, so they shouldn't bloat the
stack frame or code size of the caller.]

Pull drm fixes from Dave Airlie:
"This is the weekly drm fixes. Non-drivers there is a fbdev/sparc fix,
syncobj, ttm and buddy fixes.
On the driver side, ivpu, meson, i915 have a small fix each. Then
amdgpu and xe have a bunch. Nouveau has some minor uapi additions to
give userspace some useful info along with a Kconfig change to allow
the new GSP firmware paths to be used by default on the GPUs it
supports.
Seems about the usual amount for this time of release cycle.
fbdev:
- fix sparc undefined reference
syncobj:
- fix sync obj fence waiting
- handle NULL fence in syncobj eventfd code
ttm:
- fix invalid free
buddy:
- fix list handling
- fix 32-bit build
meson:
- don't remove bridges from other drivers
nouveau:
- fix build warnings
- add two minor info parameters
- add a Kconfig to allow GSP by default on some GPUs
ivpu:
- allow fw to do initial tile config
i915:
- fix TV mode
amdgpu:
- Suspend/resume fixes

All the checks currently done in kvm_check_cpucfg can be realized with
early returns, so just do that to avoid extra cognitive burden related
to the return value handling.
While at it, clean up comments of _kvm_get_cpucfg_mask() and
kvm_check_cpucfg(), by removing comments that are merely restatement of
the code nearby, and paraphrasing the rest so they read more natural for
English speakers (that likely are not familiar with the actual Chinese-
influenced grammar).
No functional changes intended.

The function is not actually a getter of guest CPUCFG, but rather
validation of the input CPUCFG ID plus information about the supported
bit flags of that CPUCFG leaf. So rename it to avoid confusion.

The range check for the CPUCFG ID is wrong (should have been a ||
instead of &&) and useless in effect, so fix the obvious mistake.
Furthermore, the juggling of the temp return value is unnecessary,
because it is semantically equivalent and more readable to just
return at every switch case's end. This is done too to avoid potential
bugs in the future related to the unwanted complexity.
Also, the return value of _kvm_get_cpucfg is meant to be checked, but
this was not done, so bad CPUCFG IDs wrongly fall back to the default
case and 0 is incorrectly returned; check the return value to fix the
UAPI behavior.
While at it, also remove the redundant range check in kvm_check_cpucfg,
because out-of-range CPUCFG IDs are already rejected by the -EINVAL
as returned by _kvm_get_cpucfg().

The unflatten_and_copy_device_tree() function contains a call to
memblock_alloc(). This means that memblock is allocating memory before
any of the reserved memory regions are set aside in the arch_mem_init()
function which calls early_init_fdt_scan_reserved_mem(). Therefore,
there is a possibility for memblock to allocate from any of the
reserved memory regions.
Hence, move the call to early_init_fdt_scan_reserved_mem() to be earlier
in the init sequence, so that the reserved memory regions are set aside
before any allocations are done using memblock.

Fixes potential null pointer dereference warnings in the
dc_dmub_srv_cmd_list_queue_execute() and dc_dmub_srv_is_hw_pwr_up()
functions.
In both functions, the 'dc_dmub_srv' variable was being dereferenced
before it was checked for null. This could lead to a null pointer
dereference if 'dc_dmub_srv' is null. The fix is to check if
'dc_dmub_srv' is null before dereferencing it.
Thus moving the null checks for 'dc_dmub_srv' to the beginning of the
functions to ensure that 'dc_dmub_srv' is not null when it is
dereferenced.
Found by smatch & thus fixing the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:133 dc_dmub_srv_cmd_list_queue_execute() warn: variable dereferenced before check 'dc_dmub_srv' (see line 128)

- While working on the ring buffer I noticed that the counter used
for knowing where the end of the data is on a sub-buffer was not
a full "int" but just 20 bits. It was masked out to 0xfffff.
With the new code that allows the user to change the size of the
sub-buffer, it is theoretically possible to ask for a size
bigger than 2^20. If that happens, unexpected results may
occur as there's no code checking if the counter overflowed the
20 bits of the write mask. There are other checks to make sure
events fit in the sub-buffer, but if the sub-buffer itself is
too big, that is not checked.
Add a check in the resize of the sub-buffer to make sure that it
never goes beyond the size of the counter that holds how much
data is on it.

[Why]
Observe error message "Can't retrieve aconnector in hpd_rx_irq_offload_work"
when boot up with a mst tbt4 dock connected. After analyzing, there are few
parts needed to be adjusted:
1. hpd_rx_offload_wq[].aconnector is not initialzed before the dmub outbox
hpd_irq handler get registered which causes the error message.
2. registeration of hpd and hpd_rx_irq event for usb4 dp tunneling is not
aligned with legacy interface sequence
[How]
Put DMUB_NOTIFICATION_HPD and DMUB_NOTIFICATION_HPD_IRQ handler
registration into register_hpd_handlers() to align other interfaces and
get hpd_rx_offload_wq[].aconnector initialized earlier than that.
Leave DMUB_NOTIFICATION_AUX_REPLY registered as it was since we need that
while calling dc_link_detect(). USB4 connection status will be proactively
detected by dc_link_detect_connection_type() in amdgpu_dm_initialize_drm_device()
