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 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.
