git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi updates from Mark Brown: "The overwhelming bulk of this pull request is a change from Uwe Kleine-König which changes the return type of the remove() function to void as part of some wider work he's doing to do this for all bus types, causing updates to most SPI device drivers.

Specifics: - Use uintptr_t and offsetof() in the ACPICA code to avoid compiler warnings regarding NULL pointer arithmetic (Rafael Wysocki). - Fix possible NULL pointer dereference in acpi_ns_walk_namespace() when passed "acpi=off" in the command line (Rafael Wysocki). - Fix and clean up acpi_os_read/write_port() (Rafael Wysocki). - Introduce acpi_bus_for_each_dev() and use it for walking all ACPI device objects in the Type C code (Rafael Wysocki). - Fix the _OSC platform capabilities negotioation and prevent CPPC from being used if the platform firmware indicates that it not supported via _OSC (Rafael Wysocki). - Use ida_alloc() instead of ida_simple_get() for ACPI enumeration of devices (Rafael Wysocki). - Add AGDI and CEDT to the list of known ACPI table signatures (Ilkka Koskinen, Robert Kiraly). - Add power management debug messages related to suspend-to-idle in two places (Rafael Wysocki). - Fix __acpi_node_get_property_reference() return value and clean up that function (Andy Shevchenko, Sakari Ailus). - Fix return value of the __setup handler in the ACPI PM timer clock source driver (Randy Dunlap). - Clean up double words in two comments (Tom Rix). - Add "skip i2c clients" quirks for Lenovo Yoga Tablet 1050F/L and Nextbook Ares 8 (Hans de Goede). - Clean up frequency invariance handling on x86 in the ACPI CPPC library (Huang Rui). - Work around broken XSDT on the Advantech DAC-BJ01 board (Mark Cilissen). - Make wakeup events checks in the ACPI EC driver more straightforward and clean up acpi_ec_submit_event() (Rafael Wysocki). - Make it possible to obtain the CPU capacity with the help of CPPC information (Ionela Voinescu). - Improve fine grained fan control in the ACPI fan driver and document it (Srinivas Pandruvada). - Add device HID and quirk for Microsoft Surface Go 3 to the ACPI battery driver (Maximilian Luz). - Make the ACPI driver for Intel SoCs (LPSS) let the SPI driver know the exact type of the controller (Andy Shevchenko). - Force native backlight mode on Clevo NL5xRU and NL5xNU (Werner Sembach). - Fix return value of __setup handlers in the APEI code (Randy Dunlap). - Add Arm Generic Diagnostic Dump and Reset device driver (Ilkka Koskinen). - Limit printable size of BERT table data (Darren Hart). - Fix up HEST and GHES initialization (Shuai Xue). - Update the ACPI device enumeration documentation and unify the ASL style in GPIO-related examples (Andy Shevchenko)" * tag 'acpi-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (52 commits) clocksource: acpi_pm: fix return value of __setup handler ACPI: bus: Avoid using CPPC if not supported by firmware Revert "ACPI: Pass the same capabilities to the _OSC regardless of the query flag" ACPI: video: Force backlight native for Clevo NL5xRU and NL5xNU arm64, topology: enable use of init_cpu_capacity_cppc() arch_topology: obtain cpu capacity using information from CPPC x86, ACPI: rename init_freq_invariance_cppc() to arch_init_invariance_cppc() ACPI: AGDI: Add driver for Arm Generic Diagnostic Dump and Reset device ACPI: tables: Add AGDI to the list of known table signatures ACPI/APEI: Limit printable size of BERT table data ACPI: docs: gpio-properties: Unify ASL style for GPIO examples ACPI / x86: Work around broken XSDT on Advantech DAC-BJ01 board ACPI: APEI: fix return value of __setup handlers x86/ACPI: CPPC: Move init_freq_invariance_cppc() into x86 CPPC x86: Expose init_freq_invariance() to topology header x86/ACPI: CPPC: Move AMD maximum frequency ratio setting function into x86 CPPC x86/ACPI: CPPC: Rename cppc_msr.c to cppc.c ACPI / x86: Add skip i2c clients quirk for Lenovo Yoga Tablet 1050F/L ACPI / x86: Add skip i2c clients quirk for Nextbook Ares 8 ACPICA: Avoid walking the ACPI Namespace if it is not there ...

2022-03-20kvm/emulate: Fix SETcc emulation function offsets with SLSBorislav Petkov1-2/+17
The commit in Fixes started adding INT3 after RETs as a mitigation against straight-line speculation. The fastop SETcc implementation in kvm's insn emulator uses macro magic to generate all possible SETcc functions and to jump to them when emulating the respective instruction. However, it hardcodes the size and alignment of those functions to 4: a three-byte SETcc insn and a single-byte RET. BUT, with SLS, there's an INT3 that gets slapped after the RET, which brings the whole scheme out of alignment: 15: 0f 90 c0 seto %al 18: c3 ret 19: cc int3 1a: 0f 1f 00 nopl (%rax) 1d: 0f 91 c0 setno %al 20: c3 ret 21: cc int3 22: 0f 1f 00 nopl (%rax) 25: 0f 92 c0 setb %al 28: c3 ret 29: cc int3 and this explodes like this: int3: 0000 [#1] PREEMPT SMP PTI CPU: 0 PID: 2435 Comm: qemu-system-x86 Not tainted 5.17.0-rc8-sls #1 Hardware name: Dell Inc.

2022-03-16Revert "arm64: dts: freescale: Fix 'interrupt-map' parent address cells"Vladimir Oltean3-36/+36
This reverts commit 869f0ec048dc8fd88c0b2003373bd985795179fb. That updated the expected device tree binding format for the ls-extirq driver, without also updating the parsing code (ls_extirq_parse_map) to the new format. The context is that the ls-extirq driver uses the standard "interrupt-map" OF property in a non-standard way, as suggested by Rob Herring during review: https://lore.kernel.org/lkml/20190927161118.GA19333@bogus/ This has turned out to be problematic, as Marc Zyngier discovered through commit 041284181226 ("of/irq: Allow matching of an interrupt-map local to an interrupt controller"), later fixed through commit de4adddcbcc2 ("of/irq: Add a quirk for controllers with their own definition of interrupt-map"). Marc's position, expressed on multiple opportunities, is that: (a) [ making private use of the reserved "interrupt-map" name in a driver ] "is wrong, by the very letter of what an interrupt-map means. If the interrupt map points to an interrupt controller, that's the target for the interrupt." https://lore.kernel.org/lkml/87k0g8jlmg.wl-maz@kernel.org/ (b) [ updating the driver's bindings to accept a non-reserved name for this property, as an alternative, is ] "is totally pointless. These machines have been in the wild for years, and existing DTs will be there *forever*." https://lore.kernel.org/lkml/87ilvrk1r0.wl-maz@kernel.org/ Considering the above, the Linux kernel has quirks in place to deal with the ls-extirq's non-standard use of the "interrupt-map". These quirks may be needed in other operating systems that consume this device tree, yet this is seen as the only viable solution. Therefore, the premise of the patch being reverted here is invalid. It doesn't matter whether the driver, in its non-standard use of the property, complies to the standard format or not, since this property isn't expected to be used for interrupt translation by the core. This change restores LS1088A, LS2088A/LS2085A and LX2160A to their previous bindings, which allows these systems to continue to use external interrupt lines with the correct polarity.

2022-03-16PM: hibernate: Honour ACPI hardware signature by default for virtual guestsDavid Woodhouse1-2/+21
The ACPI specification says that OSPM should refuse to restore from hibernate if the hardware signature changes, and should boot from scratch. However, real BIOSes often vary the hardware signature in cases where we *do* want to resume from hibernate, so Linux doesn't follow the spec by default. However, in a virtual environment there's no reason for the VMM to vary the hardware signature *unless* it wants to trigger a clean reboot as defined by the ACPI spec. So enable the check by default if a hypervisor is detected. Signed-off-by: David Woodhouse <dwmw@amazon.co.uk> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

The Do you have a strange power saving mode enabled? hint when unknown NMI happens dates back to i386 stone age, and isn't currently really helpful. Unknown NMIs are coming for many different reasons (broken firmware, faulty hardware, ...) and rarely have anything to do with 'strange power saving mode' (whatever that even is). Just remove it as it's largerly misleading.
