Subject: [Patch V3 0/4] Code refine for Intel IOMMU

These four patches try to refine the Intel IOMMU.                                                                                     

Patch 1/2 tries to make it more user friendly by add a zero-sized array in                                                            
some dmar data structure.                                                                                                             
Patch 3 move the ckeck of Register Base Address ahead to avoid cleanup when it                                                        
is NULL.                                                                                                                              
Patch 4 re-use dmar_walk_dmar_table() to make the code easy to understand.

V3:
  * change hdr to drhd from type acpi_dmar_header to acpi_dmar_hardware_unit 
  * add reason in changelog for the change in Patch 1

V2:
  * add patch 3 and 4

Wei Yang (4):
  iommu/vt-d: replace *hdr with drhd[0] in struct dmar_drhd_unit
  iommu/vt-d: use zero-sized array in DMAR related ACPI structures
  iommu/vt-d: check Register Base Address at the beginning of
    dmar_parse_one_drhd()
  iommu/vt-d: refine dmar_acpi_dev_scope_init() with
    dmar_walk_dmar_table()
