Merge tag 'kvmarm-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64 updates for 6.5

- Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of block splitting in the stage-2
fault path.

- Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with
services that live in the Secure world. pKVM intervenes on FF-A calls
to guarantee the host doesn't misuse memory donated to the hyp or a
pKVM guest.

- Support for running the split hypervisor with VHE enabled, known as
'hVHE' mode. This is extremely useful for testing the split
hypervisor on VHE-only systems, and paves the way for new use cases
that depend on having two TTBRs available at EL2.

- Generalized framework for configurable ID registers from userspace.
KVM/arm64 currently prevents arbitrary CPU feature set configuration
from userspace, but the intent is to relax this limitation and allow
userspace to select a feature set consistent with the CPU.

- Enable the use of Branch Target Identification (FEAT_BTI) in the
hypervisor.

- Use a separate set of pointer authentication keys for the hypervisor
when running in protected mode, as the host is untrusted at runtime.

- Ensure timer IRQs are consistently released in the init failure
paths.

- Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps
(FEAT_EVT), as it is a register commonly read from userspace.

- Erratum workaround for the upcoming AmpereOne part, which has broken
hardware A/D state management.

As a consequence of the hVHE series reworking the arm64 software
features framework, the for-next/module-alloc branch from the arm64 tree
comes along for the ride.

arm64: add hw_nmi_get_sample_period for preparation of lockup detector

Set safe maximum CPU frequency to 5 GHz in case a particular platform
doesn't implement cpufreq driver. Although, architecture doesn't put any
restrictions on maximum frequency but 5 GHz seems to be safe maximum given
the available Arm CPUs in the market which are clocked much less than 5
GHz.

On the other hand, we can't make it much higher as it would lead to a
large hard-lockup detection timeout on parts which are running slower (eg.
1GHz on Developerbox) and doesn't possess a cpufreq driver.

arm64: module: mandate MODULE_PLTS

Contemporary kernels and modules can be relatively large, especially
when common debug options are enabled. Using GCC 12.1.0, a v6.3-rc7
defconfig kernel is ~38M, and with PROVE_LOCKING + KASAN_INLINE enabled
this expands to ~117M. Shanker reports [1] that the NVIDIA GPU driver
alone can consume 110M of module space in some configurations.

Both KASLR and ARM64_ERRATUM_843419 select MODULE_PLTS, so anyone
wanting a kernel to have KASLR or run on Cortex-A53 will have
MODULE_PLTS selected. This is the case in defconfig and distribution
kernels (e.g. Debian, Android, etc).

Practically speaking, this means we're very likely to need MODULE_PLTS
and while it's almost guaranteed that MODULE_PLTS will be selected, it
is possible to disable support, and we have to maintain some awkward
special cases for such unusual configurations.

This patch removes the MODULE_PLTS config option, with the support code
always enabled if MODULES is selected. This results in a slight
simplification, and will allow for further improvement in subsequent
patches.

For any config which currently selects MODULE_PLTS, there will be no
functional change as a result of this patch.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Will Deacon:
"ACPI:

- Improve error reporting when failing to manage SDEI on AGDI device
removal

Assembly routines:

- Improve register constraints so that the compiler can make use of
the zero register instead of moving an immediate #0 into a GPR

- Allow the compiler to allocate the registers used for CAS
instructions

CPU features and system registers:

- Cleanups to the way in which CPU features are identified from the
ID register fields

- Extend system register definition generation to handle Enum types
when defining shared register fields

- Generate definitions for new _EL2 registers and add new fields for
ID_AA64PFR1_EL1

- Allow SVE to be disabled separately from SME on the kernel
command-line

Tracing:

- Support for "direct calls" in ftrace, which enables BPF tracing for
arm64

Kdump:

- Don't bother unmapping the crashkernel from the linear mapping,
which then allows us to use huge (block) mappings and reduce TLB
pressure when a crashkernel is loaded.

Memory management:

- Try again to remove data cache invalidation from the coherent DMA
allocation path

- Simplify the fixmap code by mapping at page granularity

- Allow the kfence pool to be allocated early, preventing the rest of
the linear mapping from being forced to page granularity

Perf and PMU:

- Move CPU PMU code out to drivers/perf/ where it can be reused by
the 32-bit ARM architecture when running on ARMv8 CPUs

- Fix race between CPU PMU probing and pKVM host de-privilege

- Add support for Apple M2 CPU PMU

- Adjust the generic PERF_COUNT_HW_BRANCH_INSTRUCTIONS event
dynamically, depending on what the CPU actually supports

- Minor fixes and cleanups to system PMU drivers

Stack tracing:

- Use the XPACLRI instruction to strip PAC from pointers, rather than
rolling our own function in C

- Remove redundant PAC removal for toolchains that handle this in
their builtins

- Make backtracing more resilient in the face of instrumentation

Miscellaneous:

- Fix single-step with KGDB

- Remove harmless warning when 'nokaslr' is passed on the kernel
command-line

- Minor fixes and cleanups across the board"

arm64: perf: Move PMUv3 driver to drivers/perf

Having the ARM PMUv3 driver sitting in arch/arm64/kernel is getting
in the way of being able to use perf on ARMv8 cores running a 32bit
kernel, such as

arm64: perf: Move PMUv3 driver to drivers/perf

Having the ARM PMUv3 driver sitting in arch/arm64/kernel is getting
in the way of being able to use perf on ARMv8 cores running a 32bit
kernel, such as 32bit KVM guests.

This patch moves it into drivers/perf/arm_pmuv3.c, with an include
file in include/linux/perf/arm_pmuv3.h. The only thing left in
arch/arm64 is some mundane perf stuff.
