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"

KVM: arm64: selftests: Replace str_with_index with strdup_printf

The original author of aarch64/get-reg-list.c (me) was wearing
tunnel vision goggles when implementing str_with_index(). There's
no reason to have such a special case string function. Instead,
take inspiration from glib and implement strdup_printf. The
implementation builds on vasprintf() which requires _GNU_SOURCE,
but we require _GNU_SOURCE in most files already.

KVM: selftests: Add guest_snprintf() to KVM selftests

Add a local version of guest_snprintf() for use in the guest.

Having a local copy allows the guest access to string formatting
options without dependencies on LIBC. LIBC is problematic because
it heavily relies on both AVX-512 instructions and a TLS, neither of
which are guaranteed to be set up in the guest.

The file guest_sprintf.c was lifted from arch/x86/boot/printf.c and
adapted to work in the guest, including the addition of buffer length.
I.e. s/sprintf/snprintf/

The functions where prefixed with "guest_" to allow guests to
explicitly call them.

A string formatted by this function is expected to succeed or die. If
something goes wrong during the formatting process a GUEST_ASSERT()
will be thrown.

KVM: selftests: Make TEST_ASSERT_EQ() output look like normal TEST_ASSERT()

Clean up TEST_ASSERT_EQ() so that the (mostly) raw code is captured in the
main assert message, not the helper macro's code. E.g. make this:

x86_64/tsc_msrs_test.c:106: __a == __b
pid=40470 tid=40470 errno=0 - Success
1 0x000000000040170e: main at tsc_msrs_test.c:106
2 0x0000000000416f23: __libc_start_call_main at libc-start.o:?
3 0x000000000041856f: __libc_start_main_impl at ??:?
4 0x0000000000401ef0: _start at ??:?
TEST_ASSERT_EQ(rounded_host_rdmsr(MSR_IA32_TSC), val + 1) failed.
rounded_host_rdmsr(MSR_IA32_TSC) is 0
val + 1 is 0x1

look like this:

x86_64/tsc_msrs_test.c:106: rounded_host_rdmsr(MSR_IA32_TSC) == val + 1
pid=5737 tid=5737 errno=0 - Success
1 0x0000000000401714: main at tsc_msrs_test.c:106
2 0x0000000000415c23: __libc_start_call_main at libc-start.o:?
3 0x000000000041726f: __libc_start_main_impl at ??:?
4 0x0000000000401e60: _start at ??:?
0 != 0x1 (rounded_host_rdmsr(MSR_IA32_TSC) != val + 1)

Opportunstically clean up the formatting of the entire macro.

RK8600/RK8601 are quite similar to the FAN53555 regulators.

RK8602/RK8603 are a bit different, having a wider output voltage
selection range, from 0.5 V to 1.5 V in 6.25 mV steps. They are used
in the Rock 5B board to power the ARM Cortex-A76 cores and the NPU.
