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. V4: * add similar change for struct dmar_atsr_unit in patch 1 * add similar change for rmrr and atsr in patch 2 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/atsr}[0] in struct dmar_{drhd/atsr}_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() drivers/iommu/dmar.c | 129 +++++++++++++++++------------------ drivers/iommu/intel-iommu.c | 26 +++---- drivers/iommu/intel_irq_remapping.c | 10 ++- include/acpi/actbl2.h | 33 +++++---- include/linux/dmar.h | 3 +- 5 files changed, 102 insertions(+), 99 deletions(-) -- 1.7.9.5
