The current code only prints PKGC-10 residency when the PKGC-10
is not reached in previous 'freeze' attempt. To debug PKGC-10 issues, we
also need to know other PKGC residency counters to better triage issues.
Ex:
1. When system is stuck in PC2, it can be caused short LTR from device.
2. When system is stuck in PC8, it can be caused by display engine.
To better triage issues, all PKGC residency are needed when issues happen.
Example log:
CPU did not enter Package C10!!! (Package C10 cnt=0x0)
Prev Package C2 cnt = 0x2191a325de, Current Package C2 cnt = 0x21aba30724
Prev Package C3 cnt = 0x0, Current Package C3 cnt = 0x0
Prev Package C6 cnt = 0x0, Current Package C6 cnt = 0x0
Prev Package C7 cnt = 0x0, Current Package C7 cnt = 0x0
Prev Package C8 cnt = 0x0, Current Package C8 cnt = 0x0
Prev Package C9 cnt = 0x0, Current Package C9 cnt = 0x0
Prev Package C10 cnt = 0x0, Current Package C10 cnt = 0x0
With this log, we can know whether it's a stuck PC2 issue, and we can
check whether the short LTR from device causes the issue.

Many older WMI drivers cannot be instantiated multiple times for
two reasons:
- they are using the legacy GUID-based WMI API
- they are singletons (with global state)
Prevent such WMI drivers from binding to WMI devices with a duplicated
GUID, as this would mean that the WMI driver will be instantiated at
least two times (one for the original GUID and one for the duplicated
GUID).
WMI drivers which can be instantiated multiple times can signal this
by setting a flag inside struct wmi_driver.

Pull x86 APIC updates from Thomas Gleixner:
"Rework of APIC enumeration and topology evaluation.
The current implementation has a couple of shortcomings:
- It fails to handle hybrid systems correctly.
- The APIC registration code which handles CPU number assignents is
in the middle of the APIC code and detached from the topology
evaluation.
- The various mechanisms which enumerate APICs, ACPI, MPPARSE and
guest specific ones, tweak global variables as they see fit or in
case of XENPV just hack around the generic mechanisms completely.
- The CPUID topology evaluation code is sprinkled all over the vendor
code and reevaluates global variables on every hotplug operation.
- There is no way to analyze topology on the boot CPU before bringing
up the APs. This causes problems for infrastructure like PERF which
needs to size certain aspects upfront or could be simplified if
that would be possible.
- The APIC admission and CPU number association logic is
incomprehensible and overly complex and needs to be kept around
after boot instead of completing this right after the APIC
enumeration.
This update addresses these shortcomings with the following changes:
- Rework the CPUID evaluation code so it is common for all vendors
and provides information about the APIC ID segments in a uniform
way independent of the number of segments (Thread, Core, Module,
..., Die, Package) so that this information can be computed instead
of rewriting global variables of dubious value over and over.
- A few cleanups and simplifcations of the APIC, IO/APIC and related
interfaces to prepare for the topology evaluation changes.
- Seperation of the parser stages so the early evaluation which tries
to find the APIC address can be seperately overridden from the late
evaluation which enumerates and registers the local APIC as further
preparation for sanitizing the topology evaluation.
- A new registration and admission logic which
- encapsulates the inner workings so that parsers and guest logic
cannot longer fiddle in it
- uses the APIC ID segments to build topology bitmaps at
registration time
- provides a sane admission logic
- allows to detect the crash kernel case, where CPU0 does not run
on the real BSP, automatically. This is required to prevent
sending INIT/SIPI sequences to the real BSP which would reset
the whole machine. This was so far handled by a tedious command
line parameter, which does not even work in nested crash
scenarios.
- Associates CPU number after the enumeration completed and
prevents the late registration of APICs, which was somehow
tolerated before.
- Converting all parsers and guest enumeration mechanisms over to the
new interfaces.
This allows to get rid of all global variable tweaking from the
parsers and enumeration mechanisms and sanitizes the XEN[PV]
handling so it can use CPUID evaluation for the first time.
- Mopping up existing sins by taking the information from the APIC ID
segment bitmaps.
This evaluates hybrid systems correctly on the boot CPU and allows
for cleanups and fixes in the related drivers, e.g. PERF.
The series has been extensively tested and the minimal late fallout
due to a broken ACPI/MADT table has been addressed by tightening the
admission logic further"

Since commit 7a36b901a6 ("ACPI: OSL: Use a threaded interrupt handler

Since the INT0002 GPIO is typically shared with the ACPI SCI the INT0002
driver must pass the same flags.
This fixes the INT0002 driver failing to probe due to following error +

Merge tag 'platform-drivers-x86-v6.8-2' fixes into pdf86/for-next
because of WMI fixes. The WMI changes done in for-next already created
a minor conflict with the fixes and WMI is actively being improved
currently so besides resolving the current conflict, this is also to
avoid further conflicts.
The activation for Scan at Field (SAF) includes a parameter to make
microcode wait for both threads to join. It's preferable to perform an
entry rendezvous before the activation to ensure that they start the
`wrmsr` close enough to each other. In some cases it has been observed
that one of the threads might be just a bit late to arrive. An entry
rendezvous reduces the likelihood of these cases occurring.
Add an entry rendezvous to ensure the activation on both threads happen
close enough to each other.

ARRAY_BIST requires the test to be invoked only from one of the HT
siblings of a core. If the other sibling was in mwait(), that didn't
permit the test to complete and resulted in several retries before the
test could finish.
The exit rendezvous was introduced to keep the HT sibling busy until
the primary CPU completed the test to avoid those retries. What is
actually needed is to ensure that both the threads rendezvous *before*
the wrmsr to trigger the test to give good chance to complete the test.
The `stop_machine()` function returns only after all the CPUs complete
running the function, and provides an exit rendezvous implicitly.
In kernel/stop_machine.c::multi_cpu_stop(), every CPU in the mask
needs to complete reaching MULTI_STOP_RUN. When all CPUs complete, the
state machine moves to next state, i.e MULTI_STOP_EXIT. Thus the
underlying API stop_core_cpuslocked() already provides an exit
rendezvous.
Add the rendezvous earlier in order to ensure the wrmsr is triggered
after all CPUs reach the do_array_test(). Remove the exit rendezvous
since stop_core_cpuslocked() already guarantees that.

The sysfs callback functions such as show_domain_id() are written as if
they are going to be called by dev_attr_show() but as the above message
shows, they are instead called by kobj_attr_show(). kCFI checks that the
destination of an indirect jump has the exact same type as the prototype
of the function pointer it is called through and fails when they do not.
These callbacks are called through kobj_attr_show() because
uncore_root_kobj was initialized with kobject_create_and_add(), which
means uncore_root_kobj has a ->sysfs_ops of kobj_sysfs_ops from
kobject_create(), which uses kobj_attr_show() as its ->show() value.
The only reason there has not been a more noticeable problem until this
point is that 'struct kobj_attribute' and 'struct device_attribute' have
the same layout, so getting the callback from container_of() works the
same with either value.
Change all the callbacks and their uses to be compatible with
kobj_attr_show() and kobj_attr_store(), which resolves the kCFI failure
and allows the sysfs files to work properly.

least support PC10 during suspend, move the LTR ignore from probe to the

some laptops
- mlxbf-bootctl: Differentiate dev/production keys
- platform/surface: Correct serdev related return value to avoid
leaking errno into userspace
- Error checking fixes
The following is an automated shortlog grouped by driver:
asus-wmi:
- Change q500a_i8042_filter() into a generic i8042-filter
- disable USB0 hub on ROG Ally before suspend
- Filter Volume key presses if also reported via atkbd
- Move i8042 filter install to shared asus-wmi code
mellanox:
- Add null pointer checks for devm_kasprintf()
- Check devm_hwmon_device_register_with_groups() return value
mlxbf-bootctl:
- correctly identify secure boot with development keys
surface: aggregator:
- fix recv_buf() return value
wmi:
- Skip blocks with zero instances
Modify the external interface tpmi_get_feature_status() to get read
and write blocked instead of locked and disabled. Since auxiliary device
is not created when disabled, no use of returning disabled state. Also
locked state is not useful as feature driver can't use locked state
in a meaningful way.
Using read and write state, feature driver can decide which operations
to restrict for that feature.
