Pull kvm fixes from Paolo Bonzini: "ARM: - Correctly handle 'invariant' system registers for protected VMs - Improved handling of VNCR data aborts, including external aborts - Fixes for handling of FEAT_RAS for NV guests, providing a sane fault context during SEA injection and preventing the use of RASv1p1 fault injection hardware - Ensure that page table destruction when a VM is destroyed gives an opportunity to reschedule - Large fix to KVM's infrastructure for managing guest context loaded on the CPU, addressing issues where the output of AT emulation doesn't get reflected to the guest - Fix AT S12 emulation to actually perform stage-2 translation when necessary - Avoid attempting vLPI irqbypass when GICv4 has been explicitly disabled for a VM - Minor KVM + selftest fixes RISC-V: - Fix pte settings within kvm_riscv_gstage_ioremap() - Fix comments in kvm_riscv_check_vcpu_requests() - Fix stack overrun when setting vlenb via ONE_REG x86: - Use array_index_nospec() to sanitize the target vCPU ID when handling PV IPIs and yields as the ID is guest-controlled. - Drop a superfluous cpumask_empty() check when reclaiming SEV memory, as the common case, by far, is that at least one CPU will have entered the VM, and wbnoinvd_on_cpus_mask() will naturally handle the rare case where the set of have_run_cpus is empty. Selftests (not KVM): - Rename the is_signed_type() macro in kselftest_harness.h to is_signed_var() to fix a collision with linux/overflow.h. The collision generates compiler warnings due to the two macros having different meaning" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (29 commits) KVM: arm64: nv: Fix ATS12 handling of single-stage translation KVM: arm64: Remove __vcpu_{read,write}_sys_reg_{from,to}_cpu() KVM: arm64: Fix vcpu_{read,write}_sys_reg() accessors KVM: arm64: Simplify sysreg access on exception delivery KVM: arm64: Check for SYSREGS_ON_CPU before accessing the 32bit state RISC-V: KVM: fix stack overrun when loading vlenb RISC-V: KVM: Correct kvm_riscv_check_vcpu_requests() comment RISC-V: KVM: Fix pte settings within kvm_riscv_gstage_ioremap() KVM: arm64: selftests: Sync ID_AA64MMFR3_EL1 in set_id_regs KVM: arm64: Get rid of ARM64_FEATURE_MASK() KVM: arm64: Make ID_AA64PFR1_EL1.RAS_frac writable KVM: arm64: Make ID_AA64PFR0_EL1.RAS writable KVM: arm64: Ignore HCR_EL2.FIEN set by L1 guest's EL2 KVM: arm64: Handle RASv1p1 registers arm64: Add capability denoting FEAT_RASv1p1 KVM: arm64: Reschedule as needed when destroying the stage-2 page-tables KVM: arm64: Split kvm_pgtable_stage2_destroy() selftests: harness: Rename is_signed_type() to avoid collision with overflow.h KVM: SEV: don't check have_run_cpus in sev_writeback_caches() KVM: arm64: Correctly populate FAR_EL2 on nested SEA injection ...
