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"
