    Pull kvm fixes from Paolo Bonzini:
     "arm64:

       - Fix ITS EventID sanitisation when restoring an interrupt
         translation table.

       - Fix PPI memory leak when failing to initialise a vcpu.

       - Correctly return an error when the validation of a hypervisor trace
         descriptor fails, and limit this validation to protected mode only.

      RISC-V:

       - Fix invalid HVA warning in steal-time recording

       - Return SBI_ERR_FAILURE to guest upon OOM in pmu_event_info() and
         pmu_snapshot_set_shmem()

       - Fix NULL pointer dereference in SBI v0.1 SEND_IPI handler

       - Fix sign extension of value for MMIO loads

      s390:

       - Fix bugs in vSIE (nested virtualization) and UCONTROL, caused by
         the page table rewrite.

      x86:

       - Apply erratum #1235 workaround (disable AVIC IPI virtualization) on
         Hygon Family 18h, just like on AMD Family 17h.

       - When KVM_CAP_X86_APIC_BUS_CYCLES_NS is queried on a specific VM,
         return the VM's configured APIC bus frequency instead of the
         default. This is less confusing (read: not wrong) and makes it
         easier to fill in CPUID information that communicates the APIC bus
         frequency to the guest.

      Selftests:

       - Do not include glibc-internal <bits/endian.h>; it worked by chance
         and broke building KVM selftests with musl"
