Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm updates from Paolo Bonzini:
"The first batch of KVM patches, mostly covering x86.
ARM:
- Account stage2 page table allocations in memory stats
x86:
- Account EPT/NPT arm64 page table allocations in memory stats
- Tracepoint cleanups/fixes for nested VM-Enter and emulated MSR
accesses
- Drop eVMCS controls filtering for KVM on Hyper-V, all known
versions of Hyper-V now support eVMCS fields associated with
features that are enumerated to the guest
- Use KVM's sanitized VMCS config as the basis for the values of
nested VMX capabilities MSRs
- A myriad event/exception fixes and cleanups. Most notably, pending
exceptions morph into VM-Exits earlier, as soon as the exception is
queued, instead of waiting until the next vmentry. This fixed a
longstanding issue where the exceptions would incorrecly become
double-faults instead of triggering a vmexit; the common case of
page-fault vmexits had a special workaround, but now it's fixed for
good
- A handful of fixes for memory leaks in error paths
- Cleanups for VMREAD trampoline and VMX's VM-Exit assembly flow
- Never write to memory from non-sleepable kvm_vcpu_check_block()
- Selftests refinements and cleanups
- Misc typo cleanups
Generic:
- remove KVM_REQ_UNHALT"
* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (94 commits)
KVM: remove KVM_REQ_UNHALT
KVM: mips, x86: do not rely on KVM_REQ_UNHALT
KVM: x86: never write to memory from kvm_vcpu_check_block()
KVM: x86: Don't snapshot pending INIT/SIPI prior to checking nested events
KVM: nVMX: Make event request on VMXOFF iff INIT/SIPI is pending
KVM: nVMX: Make an event request if INIT or SIPI is pending on VM-Enter
KVM: SVM: Make an event request if INIT or SIPI is pending when GIF is set
KVM: x86: lapic does not have to process INIT if it is blocked
KVM: x86: Rename kvm_apic_has_events() to make it INIT/SIPI specific
KVM: x86: Rename and expose helper to detect if INIT/SIPI are allowed
KVM: nVMX: Make an event request when pending an MTF nested VM-Exit
KVM: x86: make vendor code check for all nested events
mailmap: Update Oliver's email address
KVM: x86: Allow force_emulation_prefix to be written without a reload
KVM: selftests: Add an x86-only test to verify nested exception queueing
KVM: selftests: Use uapi header to get VMX and SVM exit reasons/codes
KVM: x86: Rename inject_pending_events() to kvm_check_and_inject_events()
KVM: VMX: Update MTF and ICEBP comments to document KVM's subtle behavior
KVM: x86: Treat pending TRIPLE_FAULT requests as pending exceptions
KVM: x86: Morph pending exceptions to pending VM-Exits at queue time
