[PATCH v2 0/1] vhost-vdpa: skip TPM CRB memory section

[Laurent Vivier]

An error is reported for vhost-vdpa case:
qemu-kvm: vhost_vdpa_listener_region_add received unaligned region

Marc-André has proposed a fix to this problem by skipping
the memory region owned by the TPM CRB but it seems more generic
to skip not aligned memory.

v1 of this series proposed to set the RAM_PROTECTED flag for the
TPM CRB memory region.

v2:
  - do not introduce special case for TPM CRB
  - do not set RAM_PROTECTED flag for TPM CRB
  - remove error_report() and replace it with a trace
