4323516879 firmware/psci: demote suspend-mode warning to info level
On some Qualcomm platforms, like SC8280XP, the attempt to set PC mode
during boot fails with PSCI_RET_DENIED and since commit 998fcd001f
("firmware/psci: Print a warning if PSCI doesn't accept PC mode") this
is now logged at warning level:

	psci: failed to set PC mode: -3

As there is nothing users can do about the firmware behaving this way,
demote the warning to info level and clearly mark it as a firmware bug:

	psci: [Firmware Bug]: failed to set PC mode: -3

e76db6e50c ARM: SoC fixes for 6.3, part 2
As usual, most of the bug fixes address issues in the devicetree files,
 and out of these, most are for the Qualcomm and NXP platforms, including:
 
  - A missing "reserved-memory" property on LG G Watch R that
    is needed to prevent clashing with firmware
 
  - Annotations for cache coherency on multiple machines
 
  - Corrections for pinctrl, regulator, clock, iommu and power domain
    properties for i.MX and Qualcomm to correctly reflect the
    hardware settings
 
  - Firmware file names on multiple machines
    SA8540P Ride board
 
  - An incompatible change to the qcom vadc driver requires adding
    individual labels
 
  - Fix EQoS PHY reset GPIO by dropping the deprecated/wrong property
    and switch to the new bindings.
 
  - A fix for PCI bus address translation Tegra194 and Tegra234.
 
 There are also a couple of device driver fixes, addressing
 
  - A race condition in the amdtee driver
 
  - A performance regression in the Qualcomm 'llcc' driver
 
  - An unitialized variable use NXP i.MX "weim" driver
 
  - Error handling issues in Qualcomm "rmtfs", and "scm"
    drivers and the Arm scmi firmware driver

0b1d9debe3 efi/libstub: randomalloc: Return EFI_OUT_OF_RESOURCES on failure
The logic in efi_random_alloc() will iterate over the memory map twice,
once to count the number of candidate slots, and another time to locate
the chosen slot after randomization.

If there is insufficient memory to do the allocation, the second loop
will run to completion without actually having located a slot, but we
currently return EFI_SUCCESS in this case, as we fail to initialize
status to the appropriate error value of EFI_OUT_OF_RESOURCES.

fc3608aaa5 efi/libstub: Use relocated version of kernel's struct screen_info
In some cases, we expose the kernel's struct screen_info to the EFI stub
directly, so it gets populated before even entering the kernel.  This
means the early console is available as soon as the early param parsing
happens, which is nice. It also means we need two different ways to pass
this information, as this trick only works if the EFI stub is baked into
the core kernel image, which is not always the case.

Huacai reports that the preparatory refactoring that was needed to
implement this alternative method for zboot resulted in a non-functional
efifb earlycon for other cases as well, due to the reordering of the
kernel image relocation with the population of the screen_info struct,
and the latter now takes place after copying the image to its new
location, which means we copy the old, uninitialized state.

So let's ensure that the same-image version of alloc_screen_info()
produces the correct screen_info pointer, by taking the displacement of
the loaded image into account.

3615c78673 efi: sysfb_efi: Fix DMI quirks not working for simpledrm
Commit 8633ef82f1 ("drivers/firmware: consolidate EFI framebuffer setup
for all arches") moved the sysfb_apply_efi_quirks() call in sysfb_init()
from before the [sysfb_]parse_mode() call to after it.
But sysfb_apply_efi_quirks() modifies the global screen_info struct which
[sysfb_]parse_mode() parses, so doing it later is too late.

This has broken all DMI based quirks for correcting wrong firmware efifb
settings when simpledrm is used.

To fix this move the sysfb_apply_efi_quirks() call back to its old place
and split the new setup of the efifb_fwnode (which requires
the platform_device) into its own function and call that at
the place of the moved sysfb_apply_efi_quirks(pd) calls.

8b3a149db4 efi: earlycon: Reprobe after parsing config tables
Commit 732ea9db9d ("efi: libstub: Move screen_info handling to common
code") reorganized the earlycon handling so that all architectures pass
the screen_info data via a EFI config table instead of populating struct
screen_info directly, as the latter is only possible when the EFI stub
is baked into the kernel (and not into the decompressor).

However, this means that struct screen_info may not have been populated
yet by the time the earlycon probe takes place, and this results in a
non-functional early console.

So let's probe again right after parsing the config tables and
populating struct screen_info. Note that this means that earlycon output
starts a bit later than before, and so it may fail to capture issues
that occur while doing the early EFI initialization.

2ab4f4018c firmware: arm_scmi: Fix device node validation for mailbox transport
When mailboxes are used as a transport it is possible to setup the SCMI
transport layer, depending on the underlying channels configuration, to use
one or two mailboxes, associated, respectively, to one or two, distinct,
shared memory areas: any other combination should be treated as invalid.

Add more strict checking of SCMI mailbox transport device node descriptors.

11c7052998 ARM: SoC drivers for 6.3
As usual, there are lots of minor driver changes across SoC platforms
 from  NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
 These usually add support for additional chip variations in existing
 drivers, but also add features or bugfixes.
 
 The SCMI firmware subsystem gains a unified raw userspace interface
 through debugfs, which can be used for validation purposes.
 
 Newly added drivers include:
 
  - New power management drivers for StarFive JH7110, Allwinner D1 and
    Renesas RZ/V2M
 
  - A driver for Qualcomm battery and power supply status
 
  - A SoC device driver for identifying Nuvoton WPCM450 chips

a93e884edf Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1.
 
 There's a lot of changes this development cycle, most of the work falls
 into two different categories:
   - fw_devlink fixes and updates.  This has gone through numerous review
     cycles and lots of review and testing by lots of different devices.
     Hopefully all should be good now, and Saravana will be keeping a
     watch for any potential regression on odd embedded systems.
   - driver core changes to work to make struct bus_type able to be moved
     into read-only memory (i.e. const)  The recent work with Rust has
     pointed out a number of areas in the driver core where we are
     passing around and working with structures that really do not have
     to be dynamic at all, and they should be able to be read-only making
     things safer overall.  This is the contuation of that work (started
     last release with kobject changes) in moving struct bus_type to be
     constant.  We didn't quite make it for this release, but the
     remaining patches will be finished up for the release after this
     one, but the groundwork has been laid for this effort.
 
 Other than that we have in here:
   - debugfs memory leak fixes in some subsystems
   - error path cleanups and fixes for some never-able-to-be-hit
     codepaths.
   - cacheinfo rework and fixes
   - Other tiny fixes, full details are in the shortlog
 
 All of these have been in linux-next for a while with no reported
 problems.

   - Clean up how we check and print the EFI revision exposed by the
     firmware

   - Incorporate EFI memory attributes protocol definition and wire it
     up in the EFI zboot code (Evgeniy)

     This ensures that these images can execute under new and stricter
     rules regarding the default memory permissions for EFI page
     allocations (More work is in progress here)

   - CPER header cleanup (Dan Williams)

   - Use a raw spinlock to protect the EFI runtime services stack on
     arm64 to ensure the correct semantics under -rt (Pierre)

   - EFI framebuffer quirk for Lenovo Ideapad (Darrell)"

Linus Torvalds
8bf1a529cd arm64 updates for 6.3:
- Support for arm64 SME 2 and 2.1. SME2 introduces a new 512-bit
   architectural register (ZT0, for the look-up table feature) that Linux
   needs to save/restore.
 
 - Include TPIDR2 in the signal context and add the corresponding
   kselftests.
 
 - Perf updates: Arm SPEv1.2 support, HiSilicon uncore PMU updates, ACPI
   support to the Marvell DDR and TAD PMU drivers, reset DTM_PMU_CONFIG
   (ARM CMN) at probe time.
 
 - Support for DYNAMIC_FTRACE_WITH_CALL_OPS on arm64.
 
 - Permit EFI boot with MMU and caches on. Instead of cleaning the entire
   loaded kernel image to the PoC and disabling the MMU and caches before
   branching to the kernel bare metal entry point, leave the MMU and
   caches enabled and rely on EFI's cacheable 1:1 mapping of all of
   system RAM to populate the initial page tables.
 
 - Expose the AArch32 (compat) ELF_HWCAP features to user in an arm64
   kernel (the arm32 kernel only defines the values).
 
 - Harden the arm64 shadow call stack pointer handling: stash the shadow
   stack pointer in the task struct on interrupt, load it directly from
   this structure.
 
 - Signal handling cleanups to remove redundant validation of size
   information and avoid reading the same data from userspace twice.
 
 - Refactor the hwcap macros to make use of the automatically generated
   ID registers. It should make new hwcaps writing less error prone.
 
 - Further arm64 sysreg conversion and some fixes.
 
 - arm64 kselftest fixes and improvements.
 
 - Pointer authentication cleanups: don't sign leaf functions, unify
   asm-arch manipulation.
 
 - Pseudo-NMI code generation optimisations.
 
 - Minor fixes for SME and TPIDR2 handling.
 
 - Miscellaneous updates: ARCH_FORCE_MAX_ORDER is now selectable, replace
   strtobool() to kstrtobool() in the cpufeature.c code, apply dynamic
   shadow call stack in two passes, intercept pfn changes in set_pte_at()
   without the required break-before-make sequence, attempt to dump all
   instructions on unhandled kernel faults.

1f2d9ffc7a Scheduler updates in this cycle are:
- Improve the scalability of the CFS bandwidth unthrottling logic
    with large number of CPUs.
 
  - Fix & rework various cpuidle routines, simplify interaction with
    the generic scheduler code. Add __cpuidle methods as noinstr to
    objtool's noinstr detection and fix boatloads of cpuidle bugs & quirks.
 
  - Add new ABI: introduce MEMBARRIER_CMD_GET_REGISTRATIONS,
    to query previously issued registrations.
 
  - Limit scheduler slice duration to the sysctl_sched_latency period,
    to improve scheduling granularity with a large number of SCHED_IDLE
    tasks.
 
  - Debuggability enhancement on sys_exit(): warn about disabled IRQs,
    but also enable them to prevent a cascade of followup problems and
    repeat warnings.
 
  - Fix the rescheduling logic in prio_changed_dl().
 
  - Micro-optimize cpufreq and sched-util methods.
 
  - Micro-optimize ttwu_runnable()
 
  - Micro-optimize the idle-scanning in update_numa_stats(),
    select_idle_capacity() and steal_cookie_task().
 
  - Update the RSEQ code & self-tests
 
  - Constify various scheduler methods
 
  - Remove unused methods

190233164c arm64: efi: Force the use of SetVirtualAddressMap() on eMAG and Altra Max machines
Commit 550b33cfd4 ("arm64: efi: Force the use of SetVirtualAddressMap()
on Altra machines") identifies the Altra family via the family field in
the type#1 SMBIOS record. eMAG and Altra Max machines are similarly
affected but not detected with the strict strcmp test.

The type1_family smbios string is not an entirely reliable means of
identifying systems with this issue as OEMs can, and do, use their own
strings for these fields. However, until we have a better solution,
capture the bulk of these systems by adding strcmp matching for "eMAG"
and "Altra Max".

Ever since commit a28aad66da ("firmware: coreboot: Collapse platform
drivers into bus core") the Kconfig entries GOOGLE_COREBOOT_TABLE_OF
and GOOGLE_COREBOOT_TABLE_ACPI have been dead. They have no "help"
text and thus aren't user choosable. They also aren't "select"ed by
anything. They also control the compilation of no code.

Let's remove them.

b0048092f7 efi/cper, cxl: Remove cxl_err.h
While going to create include/linux/cxl.h for some cross-subsystem CXL
definitions I noticed that include/linux/cxl_err.h was already present.
That header has no reason to be global, and it duplicates the RAS
Capability Structure definitions in drivers/cxl/cxl.h. A follow-on patch
can consider unifying the CXL native error tracing with the CPER error
printing.

Also fixed up the spec reference as the latest released spec is v3.0.

1758817e7e efi: Use standard format for printing the EFI revision
The UEFI spec section 4.2.1 describes the way the human readable EFI
revision should be constructed from the 32-bit revision field in the
system table:

  The upper 16 bits of this field contain the major revision value,
  and the lower 16 bits contain the minor revision value. The minor
  revision values are binary coded decimals and are limited to the
  range of 00..99.

  When printed or displayed UEFI spec revision is referred as (Major
  revision).(Minor revision upper decimal).(Minor revision lower
  decimal) or (Major revision).(Minor revision upper decimal) in case
  Minor revision lower decimal is set to 0.

Let's adhere to this when logging the EFI revision to the kernel log.

Note that the bit about binary coded decimals is bogus, and the minor
revision lower decimal is simply the minor revision modulo 10, given the
symbolic definitions provided by the spec itself:

  #define EFI_2_40_SYSTEM_TABLE_REVISION ((2<<16) | (40))
  #define EFI_2_31_SYSTEM_TABLE_REVISION ((2<<16) | (31))
  #define EFI_2_30_SYSTEM_TABLE_REVISION ((2<<16) | (30))

234fa51db9 efi: Drop minimum EFI version check at boot
We currently pass a minimum major version to the generic EFI helper that
checks the system table magic and version, and refuse to boot if the
value is lower.

The motivation for this check is unknown, and even the code that uses
major version 2 as the minimum (ARM, arm64 and RISC-V) should make it
past this check without problems, and boot to a point where we have
access to a console or some other means to inform the user that the
firmware's major revision number made us unhappy. (Revision 2.0 of the
UEFI specification was released in January 2006, whereas ARM, arm64 and
RISC-V support where added in 2009, 2013 and 2017, respectively, so
checking for major version 2 or higher is completely arbitrary)

So just drop the check.

393e2ea30a cpuidle: drivers: firmware: psci: Dont instrument suspend code
The PSCI suspend code is currently instrumentable, which is not safe as
instrumentation (e.g. ftrace) may try to make use of RCU during idle
periods when RCU is not watching.

To fix this we need to ensure that psci_suspend_finisher() and anything
it calls are not instrumented. We can do this fairly simply by marking
psci_suspend_finisher() and the psci*_cpu_suspend() functions as
noinstr, and the underlying helper functions as __always_inline.

When CONFIG_DEBUG_VIRTUAL=y, __pa_symbol() can expand to an out-of-line
instrumented function, so we must use __pa_symbol_nodebug() within
psci_suspend_finisher().

The raw SMCCC invocation functions are written in assembly, and are not
subject to compiler instrumentation.
