The original goal with drm_edid_connector_update() was to have a single
call for updating the connector and adding probed modes, in this order,
but that turned out to be problematic. Drivers that need to update the
connector in the .detect() callback would end up updating the probed
modes as well. Turns out the callback may be called so many times that
the probed mode list fills up without bounds, and this is amplified by
add_alternate_cea_modes() duplicating the CEA modes on every call,
actually running out of memory on some machines.
Kudos to Imre Deak <imre.deak@intel.com> for explaining this to me.
Go back to having separate drm_edid_connector_update() and
drm_edid_connector_add_modes() calls. The former may be called from
.detect(), .force(), or .get_modes(), but the latter only from
.get_modes().
Unlike drm_add_edid_modes(), have drm_edid_connector_add_modes() update
the probed modes from the EDID property instead of the passed in
EDID. This is mainly to enforce two things:
1) drm_edid_connector_update() must be called before
drm_edid_connector_add_modes().
Display info and quirks are needed for parsing the modes, and we
don't want to call update_display_info() again to ensure the info is
available, like drm_add_edid_modes() does.
2) The same EDID is used for both updating the connector and adding the
probed modes.
Fortunately, the change is easy, because no driver has actually adopted
drm_edid_connector_update(). Not even i915, and that's mainly because of
the problem described above.

In the character device, the listener to address space should distinguish
whether the request is to IEC 61883-1 FCP region or not. The user space
application needs to access to the object of request in enough later by
read(2), while the core function releases the object of request in the FCP
case after completing the callback to handler.
The handler guarantees the access safe by some way. It's done by
duplication of the object after NULL check to the request, since core
function passes NULL in the FCP case. It's inconvenient since the object
of request includes some helpful information. It's better to add another
way to check whether the request is to FCP region or not.
Conveniently the file of transaction layer includes local implementation
for the purpose. This commit moves it to module local file and use it
instead of the NULL check, then the result of check is stored to
per-client data for the inbound transaction so that the result can be
referred by later to release the data.

Xen on x86 boots dom0 in EFI mode but without providing a memory map.
This means that some consistency checks we would like to perform on
configuration tables or other data structures in memory are not
currently possible. Xen does, however, expose EFI memory descriptor
info via a Xen hypercall, so let's wire that up instead. It turns out
that the returned information is not identical to what Linux's
efi_mem_desc_lookup would return: the address returned is the address
passed to the hypercall, and the size returned is the number of bytes
remaining in the configuration table. However, none of the callers of
efi_mem_desc_lookup() currently care about this. In the future, Xen may
gain a hypercall that returns the actual start address, which can be
used instead.

For that swap the OGM vs. unicast-tvlv packet boolean indicator to an
explicit unsigned integer packet type variable. And provide the skb
to a call to batadv_tvlv_containers_process(), as later the multicast

the full skb for forwarding. Forwarding will be invoked from the
multicast packet's TVLVs' contents later.

1588 driver loses about 1us in adjtime operation at PTP slave
This is because adjtime operation uses a slow non-atomic tmr_cnt_read()
followed by tmr_cnt_write() operation.
In the above sequence, since the timer counter operation keeps
incrementing, it leads to latency. The tmr_offset register
(which is added to TMR_CNT_H/L register giving the current time)
must be programmed with the delta nanoseconds.

that there is a clear separation of C22 and C45, this scheme is no
longer used. Remove all the #defines and helpers, to prevent any code

The previous commit implemented destroy_if_dynptr_stack_slot. It
destroys the dynptr which given spi belongs to, but still doesn't
invalidate the slices that belong to such a dynptr. While for the case
of referenced dynptr, we don't allow their overwrite and return an error
early, we still allow it and destroy the dynptr for unreferenced dynptr.
To be able to enable precise and scoped invalidation of dynptr slices in
this case, we must be able to associate the source dynptr of slices that
have been obtained using bpf_dynptr_data. When doing destruction, only
slices belonging to the dynptr being destructed should be invalidated,
and nothing else. Currently, dynptr slices belonging to different
dynptrs are indistinguishible.
Hence, allocate a unique id to each dynptr (CONST_PTR_TO_DYNPTR and
those on stack). This will be stored as part of reg->id. Whenever using
bpf_dynptr_data, transfer this unique dynptr id to the returned
PTR_TO_MEM_OR_NULL slice pointer, and store it in a new per-PTR_TO_MEM
dynptr_id register state member.
Finally, after establishing such a relationship between dynptrs and
their slices, implement precise invalidation logic that only invalidates
slices belong to the destroyed dynptr in destroy_if_dynptr_stack_slot.

are expected to be available even if CONFIG_ACPI=n. This is not
the case for _DSM related methods. Add stubs for
acpi_evaluate_dsm_typed() and acpi_check_dsm() methods.

Current some drivers(like iscsi) call transport_register_device()
failed, they don't call transport_destroy_device() to release the
memory allocated in transport_setup_device(), because they don't
know what was done, it should be internal thing to release the
resource in register function. So fix this leak by calling destroy
function inside register function.

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into driver-core-next
Sudeep writes:
"cacheinfo and arch_topology updates for v6.3
The main change is to build the cache topology information for all
the CPUs from the primary CPU. Currently the cacheinfo for secondary CPUs
is created during the early boot on the respective CPU itself. Preemption
and interrupts are disabled at this stage. On PREEMPT_RT kernels, allocating
memory and even parsing the PPTT table for ACPI based systems triggers a:
'BUG: sleeping function called from invalid context'
To prevent this bug, the cacheinfo is now allocated from the primary CPU
when preemption and interrupts are enabled and before booting secondary
CPUs. The cache levels/leaves are computed from DT/ACPI PPTT information
only, without relying on any architecture specific mechanism if done so
early.
The other minor change included here is to handle shared caches at
different levels when not all the CPUs on the system have the same
cache hierarchy."

Implement support for a new note type NT_ARM64_ZT providing access to
ZT0 when implemented. Since ZT0 is a register with constant size this is
much simpler than for other SME state.
As ZT0 is only accessible when PSTATE.ZA is set writes to ZT0 cause
PSTATE.ZA to be set, the main alternative would be to return -EBUSY in
this case but this seemed more constructive. Practical users are also
going to be working with ZA anyway and have some understanding of the
state.

Provide an `ecr_writable' parameter to `__parport_pc_probe_port' so that
callers can specify a mask of bits to modify on ECR writes.
To avoid the need for separate bit set and bit clear masks always set
bit 0 whenever a non-zero mask has been set, as all the currently known
cases where a mask is required, that is Oxford Semiconductor devices, do
require this bit to be set. If further cases are discovered where the
bit is required to be clear, we can update code accordingly, but chances
are very low as the bit is supposed to be read-only[1].
Skip ECR probing, which can be problematic as the Oxford Semiconductor
OX12PCI840 part has been reported to lock up on setting bit 2, whenever
a non-zero mask has been requested by a port subdriver, assuming that
the ECR must be there if the subdriver has requested a specific way to
access it.

Define the device isolation strategy by the device driver. The
user configures a hardware error threshold value by uacce interface.
If the number of hardware errors exceeds the value of setting error
threshold in one hour. The device will not be available in user space.
The VF device use the PF device isolation strategy. All the hardware
errors are processed by PF driver.

UACCE adds the hardware error isolation feature. To improve service
reliability, some uacce devices that frequently encounter hardware
errors are isolated. Therefore, this feature is added.
Users can configure the hardware error threshold by 'isolate_strategy'
sysfs node. The user space can get the device isolated state by 'isolate'
sysfs node. If the number of device errors exceeds the configured error
threshold, the device will be isolated. It means the uacce device is
unavailable.
