  KVM: SVM: Disable AVIC IPI virtualization on Hygon Family 18h (erratum #1235) (2026-05-23 10:09:04 +0200)

----------------------------------------------------------------
Arm:

- 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.
