ACPI: Use fallthrough pseudo-keyword
Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

When /sys/firmware/acpi/pm_profile is read, sysfs_kf_seq_show is called,
which in turn calls kobj_attr_show, which gets the ->show callback
member by calling container_of on attr (casting it to struct
kobj_attribute) then calls it.
There is a CFI violation because pm_profile_attr is of type
struct device_attribute but kobj_attr_show calls ->show expecting it
to be from struct kobj_attribute. CFI checking ensures that function
pointer types match when doing indirect calls. Fix pm_profile_attr to
be defined in terms of kobj_attribute so there is no violation or
mismatch.

ACPI: configfs: Disallow loading ACPI tables when locked down
Like other vectors already patched, this one here allows the root user to load ACPI tables, which enables arbitrary physical address writes, which in turn makes it possible to disable lockdown. Prevents this by checking the lockdown status before allowing a new ACPI table to be installed. The link in the trailer shows a PoC of how this might be used.

ACPI: PM: Avoid using power resources if there are none for D0
As recently reported, some platforms provide a list of power
resources for device power state D3hot, through the _PR3 object,
but they do not provide a list of power resources for device power
state D0.
Among other things, this causes acpi_device_get_power() to return
D3hot as the current state of the device in question if all of the
D3hot power resources are "on", because it sees the power_resources
flag set and calls acpi_power_get_inferred_state() which finds that
D3hot is the shallowest power state with all of the associated power
resources turned "on", so that's what it returns. Moreover, that
value takes precedence over the acpi_dev_pm_explicit_get() return
value, because it means a deeper power state. The device may very
well be in D0 physically at that point, however.
Moreover, the presence of _PR3 without _PR0 for a given device
means that only one D3-level power state can be supported by it.
Namely, because there are no power resources to turn "off" when
transitioning the device from D0 into D3cold (which should be
supported since _PR3 is present), the evaluation of _PS3 should
be sufficient to put it straight into D3cold, but this means that
the effect of turning "on" the _PR3 power resources is unclear,
so it is better to avoid doing that altogether. Consequently,
there is no practical way do distinguish D3cold from D3hot for
the device in question and the power states of it can be labeled
so that D3hot is the deepest supported one (and Linux assumes
that putting a device into D3hot via ACPI may cause power to be
removed from it anyway, for legacy reasons).
To work around the problem described above modify the ACPI
enumeration of devices so that power resources are only used
for device power management if the list of D0 power resources
is not empty and make it mart D3cold as supported only if that
is the case and the D3hot list of power resources is not empty
too.

- Rework the system-wide PM driver flags to make them easier to
understand and use and update their documentation (Rafael Wysocki,
Alan Stern).
- Allow cpuidle governors to be switched at run time regardless of
the kernel configuration and update the related documentation
accordingly (Hanjun Guo).
- Improve the resume device handling in the user space hibernarion
interface code (Domenico Andreoli).
- Document the intel-speed-select sysfs interface (Srinivas
Pandruvada).
- Make the ACPI code handing suspend to idle print more debug
messages to help diagnose issues with it (Rafael Wysocki).
- Fix a helper routine in the cpufreq core and correct a typo in the
struct cpufreq_driver kerneldoc comment (Rafael Wysocki, Wang
Wenhu).
- Update cpufreq drivers:
- Make the intel_pstate driver start in the passive mode by
default on systems without HWP (Rafael Wysocki).
- Add i.MX7ULP support to the imx-cpufreq-dt driver and add
i.MX7ULP to the cpufreq-dt-platdev blacklist (Peng Fan).
- Convert the qoriq cpufreq driver to a platform one, make the
platform code create a suitable device object for it and add
platform dependencies to it (Mian Yousaf Kaukab, Geert
Uytterhoeven).
- Fix wrong compatible binding in the qcom driver (Ansuel Smith).
- Build the omap driver by default for ARCH_OMAP2PLUS (Anders
Roxell).
- Add r8a7742 SoC support to the dt cpufreq driver (Lad
Prabhakar).
- Update cpuidle core and drivers:
- Fix three reference count leaks in error code paths in the
cpuidle core (Qiushi Wu).
- Convert Qualcomm SPM to a generic cpuidle driver (Stephan
Gerhold).
- Fix up the execution order when entering a domain idle state in
the PSCI driver (Ulf Hansson).
- Fix a reference counting issue related to clock management and
clean up two oddities in the PM-runtime framework (Rafael Wysocki,
Andy Shevchenko).
- Add ElkhartLake support to the Intel RAPL power capping driver and
remove an unused local MSR definition from it (Jacob Pan, Sumeet
Pawnikar).
- Update devfreq core and drivers:
- Replace strncpy() with strscpy() in the devfreq core and use
lockdep asserts instead of manual checks for a locked mutex in
it (Dmitry Osipenko, Krzysztof Kozlowski).
- Add a generic imx bus scaling driver and make it register an
interconnect device (Leonard Crestez, Gustavo A. R. Silva).
- Make the cpufreq notifier in the tegra30 driver take boosting
into account and delete an unuseful error message from that
driver (Dmitry Osipenko, Markus Elfring).

arm64 updates for 5.8
- Branch Target Identification (BTI)
* Support for ARMv8.5-BTI in both user- and kernel-space. This
allows branch targets to limit the types of branch from which
they can be called and additionally prevents branching to
arbitrary code, although kernel support requires a very recent
toolchain.
* Function annotation via SYM_FUNC_START() so that assembly
functions are wrapped with the relevant "landing pad"
instructions.
* BPF and vDSO updates to use the new instructions.
* Addition of a new HWCAP and exposure of BTI capability to
userspace via ID register emulation, along with ELF loader
support for the BTI feature in .note.gnu.property.
* Non-critical fixes to CFI unwind annotations in the sigreturn
trampoline.
- Shadow Call Stack (SCS)
* Support for Clang's Shadow Call Stack feature, which reserves
platform register x18 to point at a separate stack for each
task that holds only return addresses. This protects function
return control flow from buffer overruns on the main stack.
* Save/restore of x18 across problematic boundaries (user-mode,
hypervisor, EFI, suspend, etc).
* Core support for SCS, should other architectures want to use it
too.
* SCS overflow checking on context-switch as part of the existing
stack limit check if CONFIG_SCHED_STACK_END_CHECK=y.
- CPU feature detection
* Removed numerous "SANITY CHECK" errors when running on a system
with mismatched AArch32 support at EL1. This is primarily a
concern for KVM, which disabled support for 32-bit guests on
such a system.
* Addition of new ID registers and fields as the architecture has
been extended.
- Perf and PMU drivers
* Minor fixes and cleanups to system PMU drivers.
- Hardware errata
* Unify KVM workarounds for VHE and nVHE configurations.
* Sort vendor errata entries in Kconfig.
- Secure Monitor Call Calling Convention (SMCCC)
* Update to the latest specification from Arm (v1.2).
* Allow PSCI code to query the SMCCC version.
- Software Delegated Exception Interface (SDEI)
* Unexport a bunch of unused symbols.
* Minor fixes to handling of firmware data.
- Pointer authentication
* Add support for dumping the kernel PAC mask in vmcoreinfo so
that the stack can be unwound by tools such as kdump.
* Simplification of key initialisation during CPU bringup.
- BPF backend
* Improve immediate generation for logical and add/sub
instructions.
- vDSO
- Minor fixes to the linker flags for consistency with other
architectures and support for LLVM's unwinder.
- Clean up logic to initialise and map the vDSO into userspace.
- ACPI
- Work around for an ambiguity in the IORT specification relating
to the "num_ids" field.
- Support _DMA method for all named components rather than only
PCIe root complexes.
- Minor other IORT-related fixes.
- Miscellaneous
* Initialise debug traps early for KGDB and fix KDB cacheflushing

ACPI: DPTF: Add battery participant driver
This driver adds support for Dynamic Platform and Thermal Framework battery participant device support. These attributes are presented via sysfs interface under the platform device for the battery participant: $ls /sys/bus/platform/devices/INT3532:00/dptf_battery current_discharge_capbility_ma max_platform_power_mw no_load_voltage_mv high_freq_impedance_mohm max_steady_state_power_mw Refer to the documentation at Documentation/ABI/testing/sysfs-platform-dptf for details. Here the implementation reuses existing dptf-power.c as the motivation and processing is same. It also shares one ACPI method. Here this change is using participant type, "PTYP" method to identify and do different processing. By using participant type, create/delete either "dptf_power" or "dptf_battery" attribute group and send notifications. The particpant type for for the battery participant is 0x0C. ACPI methods description: PMAX (Intel(R) Dynamic Tuning Platform Max Power Supplied by Battery): This object evaluates to the maximum platform power that can be supported by the battery in milli watts. PBSS (Intel(R) Dynamic Tuning Power Battery Steady State): This object returns the max sustained power for battery in milli watts. RBHF (Intel(R) Dynamic Tuning High Frequency Impedance): This object returns high frequency impedance value that can be obtained from battery fuel gauge. VBNL (Intel(R) Dynamic Tuning No-Load Voltage) This object returns battery instantaneous no-load voltage that can be obtained from battery fuel gauge in milli volts CMPP (Intel(R) Dynamic Tuning Current Discharge Capability) This object returns battery discharge current capability obtained from battery fuel gauge milli amps.

ACPI: DPTF: Additional sysfs attributes for power participant driver
Add two additional attributes to the existing power participant driver:
rest_of_platform_power_mw: (RO) Shows the rest of worst case platform
power in mW outside of S0C. This will help in power distribution to SoC
and rest of the system. For example on a test system, this value is 2.5W
with a 15W TDP SoC. Based on the adapter rating (adapter_rating_mw), user
space software can decide on proper power allocation to SoC to improve
short term performance via powercap/RAPL interface.
prochot_confirm: (WO) Confirm EC about a prochot notification.
Also userspace is notified via sysfs_notify(), whenever power source or
rest of the platform power is changed. So user space can use poll()
system call on those attributes.
The ACPI methods used in this patch are as follows:
PROP
This object evaluates to the rest of worst case platform power in mW.
Bits:
23:0 Worst case rest of platform power in mW.
PBOK
PBOK is a method designed to provide a mechanism for OSPM to change power
setting before EC can de-assert a PROCHOT from a device. The EC may
receive several PROCHOTs, so it has a sequence number attached to PSRC
(read via existing attribute "platform_power_source"). Once OSPM takes
action for a PSRC change notification, it can call PBOK method to confirm
with the sequence number.
Bits:
3:0 Power Delivery State Change Sequence number
30 Reserved
31 0 – Not OK to de-assert PROCHOT
1 – OK to de-assert PROCHOT
PSRC (Platform Power Source): Not new in this patch but for
documentation for new bits
This object evaluates to an integer that represents the system power
source as well as the power delivery state change sequence number.
Bits:
3:0 The current power source as an integer for AC, DC, USB, Wireless.
0 = DC, 1 = AC, 2 = USB, 3 = Wireless Charging
7:4 Power Delivery State Change Sequence Number. Default value is 0
Notifications:
0x81: (Power State Change) Used to notify when the power source has
changed.
0x84: (PROP change) Used to notify when the platform rest of power has
changed.

ACPI: video: Use native backlight on Acer TravelMate 5735Z
Currently, changing the brightness of the internal display of the Acer TravelMate 5735Z does not work. Pressing the function keys or changing the slider, GNOME Shell 3.36.2 displays the OSD (five steps), but the brightness does not change. The Acer TravelMate 5735Z shipped with Windows 7 and as such does not trigger our "win8 ready" heuristic for preferring the native backlight interface. Still ACPI backlight control doesn't work on this model, where as the native (intel_video) backlight interface does work by adding `acpi_backlight=native` or `acpi_backlight=none` to Linux’ command line. So, add a quirk to force using native backlight control on this model.

ACPI: APEI: Kick the memory_failure() queue for synchronous errors
memory_failure() offlines or repairs pages of memory that have been discovered to be corrupt. These may be detected by an external component, (e.g. the memory controller), and notified via an IRQ. In this case the work is queued as not all of memory_failure()s work can happen in IRQ context. If the error was detected as a result of user-space accessing a corrupt memory location the CPU may take an abort instead. On arm64 this is a 'synchronous external abort', and on a firmware first system it is replayed using NOTIFY_SEA. This notification has NMI like properties, (it can interrupt IRQ-masked code), so the memory_failure() work is queued. If we return to user-space before the queued memory_failure() work is processed, we will take the fault again. This loop may cause platform firmware to exceed some threshold and reboot when Linux could have recovered from this error. For NMIlike notifications keep track of whether memory_failure() work was queued, and make task_work pending to flush out the queue. To save memory allocations, the task_work is allocated as part of the ghes_estatus_node, and free()ing it back to the pool is deferred.

ACPI: IORT: Add comments for not calling acpi_put_table()
The iort_table will be used at runtime after acpi_iort_init(), so add some comments to clarify this to make it less confusing.

ACPI: EC: PM: Avoid flushing EC work when EC GPE is inactive
Flushing the EC work while suspended to idle when the EC GPE status
is not set causes some EC wakeup events (notably power button and
lid ones) to be missed after a series of spurious wakeups on the Dell
XPS13 9360 in my office.
If that happens, the machine cannot be woken up from suspend-to-idle
by the power button or lid status change and it needs to be woken up
in some other way (eg. by a key press).
Flushing the EC work only after successful dispatching the EC GPE,
which means that its status has been set, avoids the issue, so change
the code in question accordingly.

ACPI: GED: add support for _Exx / _Lxx handler methods
Per the ACPI spec, interrupts in the range [0, 255] may be handled in AML using individual methods whose naming is based on the format _Exx or _Lxx, where xx is the hex representation of the interrupt index. Add support for this missing feature to our ACPI GED driver. Cc: v4.9+ <stable@vger.kernel.org> # v4.9+ Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Rafael J.

ACPI: IORT: Add extra message "applying workaround" for off-by-1 issue
As we already applied a workaround for the off-by-1 issue, it's good to add extra message "applying workaround" to make people less uneasy to see FW_BUG message in the boot log.
