Some ACPI i2c-devices _STA method (which is used to detect if the device
is present) use autodetection code which probes which device is present
over i2c. This requires the I2C ACPI OpRegion handler to be registered
before we enumerate i2c-clients under the i2c-adapter.
This fixes the i2c touchpad on the Lenovo ThinkBook 14-IIL and
ThinkBook 15 IIL not getting an i2c-client instantiated and thus not
working.

A detach hung is possible when a race occurs between the detach process
and the ubi background thread. The following sequences outline the race:
ubi thread: if (list_empty(&ubi->works)...
ubi detach: set_bit(KTHREAD_SHOULD_STOP, &kthread->flags)
=> by kthread_stop()
wake_up_process()
=> ubi thread is still running, so 0 is returned
ubi thread: set_current_state(TASK_INTERRUPTIBLE)
schedule()
=> ubi thread will never be scheduled again
ubi detach: wait_for_completion()
=> hung task!
To fix that, we need to check kthread_should_stop() after we set the
task state, so the ubi thread will either see the stop bit and exit or
the task state is reset to runnable such that it isn't scheduled out
indefinitely.

A metric like DRAM_BW_Use has on SkylakeX events uncore_imc/cas_count_read/
and uncore_imc/case_count_write/.
These events open 6 events per socket with pmu names of
uncore_imc_[0-5].
The current metric setup code in find_evsel_group assumes one ID will
map to 1 event to be recorded in metric_events.
For events with multiple matches, the first event is recorded in
metric_events (avoiding matching >1 event with the same name) and the
evlist_used updated so that duplicate events aren't removed when the
evlist has unused events removed.

Previously, there was no need for poke descriptors being present in
subprogram's bpf_prog_aux struct since tailcalls were simply not allowed
in them. Each subprog is JITed independently so in order to enable
JITing subprograms that use tailcalls, do the following:
- in fixup_bpf_calls() store the index of tailcall insn onto the generated
poke descriptor,
- in case when insn patching occurs, adjust the tailcall insn idx from
bpf_patch_insn_data,
- then in jit_subprogs() check whether the given poke descriptor belongs
to the current subprog by checking if that previously stored absolute
index of tail call insn is in the scope of the insns of given subprog,
- update the insn->imm with new poke descriptor slot so that while JITing
the proper poke descriptor will be grabbed
This way each of the main program's poke descriptors are distributed
across the subprograms poke descriptor array, so main program's
descriptors can be untracked out of the prog array map.
Add also subprog's aux struct to the BPF map poke_progs list by calling
on it map_poke_track().
In case of any error, call the map_poke_untrack() on subprog's aux
structs that have already been registered to prog array map.

There is a plan to use %rax for different purpose, which is storing the

adjust the BPF indirect tailcalls so that the target program will reside

With the hardware TopDown metrics feature, sample-read feature should be
supported for a topdown group, e.g., sample a non-topdown event and read
a topdown metric group. But the current perf record code errors out.
For a topdown metric group, the slots event must be the leader of the
group, but the leader slots event doesn't support sampling.
To support sample-read the topdown metric group, use the 2nd event of
the group as the "leader" for the purposes of sampling.
Only the platform with Topdown metic feature supports sample-read the
topdown group. Add arch_topdown_sample_read() to indicate whether the
topdown group supports sample-read.

required to make the branch if not equal and increment command work.
Set them when using bneq+.
A side effect of this mode requires a dummy write to TDR when both

receive data.
It is likely not possible to avoid TDR underrun errors in this mode and
they are harmless, so do not check for them.

Use a clock divider tuned to a 200MHz FSI bus frequency (the maximum). Use
of the previous divider at 200MHz results in corrupt data from endpoint
devices. Ideally the clock divider would be calculated from the FSI clock,
but that would require some significant work on the FSI driver. With FSI
frequencies slower than 200MHz, the SPI clock will simply run slower, but

A PASID is allocated for an "mm" the first time any thread binds to an
SVA-capable device and is freed from the "mm" when the SVA is unbound
by the last thread. It's possible for the "mm" to have different PASID
values in different binding/unbinding SVA cycles.
The mm's PASID (non-zero for valid PASID or 0 for invalid PASID) is
propagated to a per-thread PASID MSR for all threads within the mm
through IPI, context switch, or inherited. This is done to ensure that a
running thread has the right PASID in the MSR matching the mm's PASID.
