The series of patches are extention to EEH support for VFIO PCI devices,
which allows to inject EEH errors to VFIO PCI devices from userspace
for testing purpose.

Changelog
=========
v4 -> v5:
        * Adjusted commit log for PATCH[1]
        * Dropped the last patch which deletes VFIO_EEH_PE_STATE_* from
          uapi/linux/vfio.h because we're uncertain if there're any one
          used or will use them in future as pointed by Alex.W.
v3 -> v4:
        * Move constants for EEH PE states defined in uapi/linux/vfio.h
          to uapi/asm/eeh.h.
v2 -> v3:
        * Use offsetofend(), instead of sizeof(struct vfio_eeh_pe_op)
          to calculate argument buffer size.
v1 -> v2:
        * Use EEH_ERR_FUNC_{MIN,MAX} to validate PCI error function.
        * Put additional arguments for error injection to union in
          struct vfio_eeh_pe_op.
