Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm updates from Paolo Bonzini:
"ARM:

- Clean up vCPU targets, always returning generic v8 as the preferred
target

- Trap forwarding infrastructure for nested virtualization (used for
traps that are taken from an L2 guest and are needed by the L1
hypervisor)

- FEAT_TLBIRANGE support to only invalidate specific ranges of
addresses when collapsing a table PTE to a block PTE. This avoids
that the guest refills the TLBs again for addresses that aren't
covered by the table PTE.

- Fix vPMU issues related to handling of PMUver.

- Don't unnecessary align non-stack allocations in the EL2 VA space

- Drop HCR_VIRT_EXCP_MASK, which was never used...

- Don't use smp_processor_id() in kvm_arch_vcpu_load(), but the cpu
parameter instead

- Drop redundant call to kvm_set_pfn_accessed() in user_mem_abort()

- Remove prototypes without implementations

RISC-V:

- Zba, Zbs, Zicntr, Zicsr, Zifencei, and Zihpm support for guest

- Added ONE_REG interface for SATP mode

- Added ONE_REG interface to enable/disable multiple ISA extensions

- Improved error codes returned by ONE_REG interfaces

- Added KVM_GET_REG_LIST ioctl() implementation for KVM RISC-V

- Added get-reg-list selftest for KVM RISC-V

s390:

- PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch)

Allows a PV guest to use crypto cards. Card access is governed by
the firmware and once a crypto queue is "bound" to a PV VM every
other entity (PV or not) looses access until it is not bound
anymore. Enablement is done via flags when creating the PV VM.

- Guest debug fixes (Ilya)

x86:

- Clean up KVM's handling of Intel architectural events

- Intel bugfixes

- Add support for SEV-ES DebugSwap, allowing SEV-ES guests to use
debug registers and generate/handle #DBs

- Clean up LBR virtualization code

- Fix a bug where KVM fails to set the target pCPU during an IRTE
update

- Fix fatal bugs in SEV-ES intrahost migration

- Fix a bug where the recent (architecturally correct) change to
reinject #BP and skip INT3 broke SEV guests (can't decode INT3 to
skip it)

- Retry APIC map recalculation if a vCPU is added/enabled

- Overhaul emergency reboot code to bring SVM up to par with VMX, tie
the "emergency disabling" behavior to KVM actually being loaded,
and move all of the logic within KVM

- Fix user triggerable WARNs in SVM where KVM incorrectly assumes the
TSC ratio MSR cannot diverge from the default when TSC scaling is
disabled up related code

- Add a framework to allow "caching" feature flags so that KVM can
check if the guest can use a feature without needing to search
guest CPUID

- Rip out the ancient MMU_DEBUG crud and replace the useful bits with
CONFIG_KVM_PROVE_MMU

- Fix KVM's handling of !visible guest roots to avoid premature
triple fault injection

- Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the
API surface that is needed by external users (currently only
KVMGT), and fix a variety of issues in the process

Generic:

- Wrap kvm_{gfn,hva}_range.pte in a union to allow mmu_notifier
events to pass action specific data without needing to constantly
update the main handlers.

- Drop unused function declarations

Selftests:

- Add testcases to x86's sync_regs_test for detecting KVM TOCTOU bugs

- Add support for printf() in guest code and covert all guest asserts
to use printf-based reporting

- Clean up the PMU event filter test and add new testcases

- Include x86 selftests in the KVM x86 MAINTAINERS entry"

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm updates from Paolo Bonzini:
"ARM64:

- Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of hugepage 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.

RISC-V:

- Redirect AMO load/store misaligned traps to KVM guest

- Trap-n-emulate AIA in-kernel irqchip for KVM guest

- Svnapot support for KVM Guest

s390:

- New uvdevice secret API

- CMM selftest and fixes

- fix racy access to target CPU for diag 9c

x86:

- Fix missing/incorrect #GP checks on ENCLS

- Use standard mmu_notifier hooks for handling APIC access page

- Drop now unnecessary TR/TSS load after VM-Exit on AMD

- Print more descriptive information about the status of SEV and
SEV-ES during module load

- Add a test for splitting and reconstituting hugepages during and
after dirty logging

- Add support for CPU pinning in demand paging test

- Add support for AMD PerfMonV2, with a variety of cleanups and minor
fixes included along the way

- Add a "nx_huge_pages=never" option to effectively avoid creating NX
hugepage recovery threads (because nx_huge_pages=off can be toggled
at runtime)

- Move handling of PAT out of MTRR code and dedup SVM+VMX code

- Fix output of PIC poll command emulation when there's an interrupt

- Add a maintainer's handbook to document KVM x86 processes,
preferred coding style, testing expectations, etc.

- Misc cleanups, fixes and comments

- Miscellaneous bugfixes and cleanups

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm updates from Paolo Bonzini:
"ARM64:

- Enable the per-vcpu dirty-ring tracking mechanism, together with an
option to keep the good old dirty log around for pages that are
dirtied by something other than a vcpu.

- Switch to the relaxed parallel fault handling, using RCU to delay
page table reclaim and giving better performance under load.

- Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping
option, which multi-process VMMs such as crosvm rely on (see merge
commit 382b5b87a97d: "Fix a number of issues with MTE, such as
races on the tags being initialised vs the PG_mte_tagged flag as
well as the lack of support for VM_SHARED when KVM is involved.
Patches from Catalin Marinas and Peter Collingbourne").

- Merge the pKVM shadow vcpu state tracking that allows the
hypervisor to have its own view of a vcpu, keeping that state
private.

- Add support for the PMUv3p5 architecture revision, bringing support
for 64bit counters on systems that support it, and fix the
no-quite-compliant CHAIN-ed counter support for the machines that
actually exist out there.

- Fix a handful of minor issues around 52bit VA/PA support (64kB
pages only) as a prefix of the oncoming support for 4kB and 16kB
pages.

- Pick a small set of documentation and spelling fixes, because no
good merge window would be complete without those.

s390:

- Second batch of the lazy destroy patches

- First batch of KVM changes for kernel virtual != physical address
support

- Removal of a unused function

x86:

- Allow compiling out SMM support

- Cleanup and documentation of SMM state save area format

- Preserve interrupt shadow in SMM state save area

- Respond to generic signals during slow page faults

- Fixes and optimizations for the non-executable huge page errata
fix.

- Reprogram all performance counters on PMU filter change

- Cleanups to Hyper-V emulation and tests

- Process Hyper-V TLB flushes from a nested guest (i.e. from a L2
guest running on top of a L1 Hyper-V hypervisor)

- Advertise several new Intel features

- x86 Xen-for-KVM:

- Allow the Xen runstate information to cross a page boundary

- Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured

- Add support for 32-bit guests in SCHEDOP_poll

- Notable x86 fixes and cleanups:

- One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0).

- Reinstate IBPB on emulated VM-Exit that was incorrectly dropped
a few years back when eliminating unnecessary barriers when
switching between vmcs01 and vmcs02.

- Clean up vmread_error_trampoline() to make it more obvious that
params must be passed on the stack, even for x86-64.

- Let userspace set all supported bits in MSR_IA32_FEAT_CTL
irrespective of the current guest CPUID.

- Fudge around a race with TSC refinement that results in KVM
incorrectly thinking a guest needs TSC scaling when running on a
CPU with a constant TSC, but no hardware-enumerated TSC
frequency.

- Advertise (on AMD) that the SMM_CTL MSR is not supported

- Remove unnecessary exports

Generic:

- Support for responding to signals during page faults; introduces
new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks

Selftests:

- Fix an inverted check in the access tracking perf test, and restore
support for asserting that there aren't too many idle pages when
running on bare metal.

- Fix build errors that occur in certain setups (unsure exactly what
is unique about the problematic setup) due to glibc overriding
static_assert() to a variant that requires a custom message.

- Introduce actual atomics for clear/set_bit() in selftests

- Add support for pinning vCPUs in dirty_log_perf_test.

- Rename the so called "perf_util" framework to "memstress".

- Add a lightweight psuedo RNG for guest use, and use it to randomize
the access pattern and write vs. read percentage in the memstress
tests.

- Add a common ucall implementation; code dedup and pre-work for
running SEV (and beyond) guests in selftests.

- Provide a common constructor and arch hook, which will eventually
be used by x86 to automatically select the right hypercall (AMD vs.
Intel).

- A bunch of added/enabled/fixed selftests for ARM64, covering
memslots, breakpoints, stage-2 faults and access tracking.

- x86-specific selftest changes:

- Clean up x86's page table management.

- Clean up and enhance the "smaller maxphyaddr" test, and add a
related test to cover generic emulation failure.

- Clean up the nEPT support checks.

- Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.

- Fix an ordering issue in the AMX test introduced by recent
conversions to use kvm_cpu_has(), and harden the code to guard
against similar bugs in the future. Anything that tiggers
caching of KVM's supported CPUID, kvm_cpu_has() in this case,
effectively hides opt-in XSAVE features if the caching occurs
before the test opts in via prctl().

Documentation:

- Remove deleted ioctls from documentation

- Clean up the docs for the x86 MSR filter.

- Various fixes"
