     "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"
