    This series fixes two issues in the HiSilicon ACC VFIO migration
driver: a calltrace when a PF is passed through to a VM and migrated,
guarded by NULL pf_qm checks and pdev->is_virtfn selection; and VF
BAR2 mmap rejection on 64KB-page kernels, fixed by aligning the mmap
boundary to PAGE_SIZE while keeping byte-granular read/write
truncation. Build-tested and functionally verified.

Longfang Liu (2):
  hisi_acc_vfio_pci: fix live migration enable conditions for PF
    passthrough
  hisi_acc_vfio_pci: fix VF BAR2 mmap on 64KB page size
