This series of patches will build Heterogeneous Memory Attribute Table (HMAT)
according to the command line. The ACPI HMAT describes the memory attributes,
such as memory side cache attributes and bandwidth and latency details,
related to the System Physical Address (SPA) Memory Ranges.
The software is expected to use this information as hint for optimization.

Changelog:
v5:
    - spilt the 1-6/11 and 8/11 from patch v4 to build Memory Subsystem
    Address Range Structure(s) and System Locality Latency and Bandwidth
    Information Structure(s) firstly.
    - add 1/8 of patch v5 to simplify arm_load_dtb() (Igor)
    - drop the helper machine_num_numa_nodes() and use
    machine->numa_state->num_nodes (and numa_state->nodes) directly (Igor)
    - Add more descriptions from ACPI spec (Igor)
    - Add the reason of using stub (Igor)
    - Use GArray for NUMA memory ranges data (Igor)
    - Separate hmat_build_lb() (Igor)
    - Drop all global variables and use local variables instead (Igor)
    - Add error message when base unit < 10
    - Update the hmat-lb option example by using '-numa cpu'
    and '-numa memdev' (Igor)

v4:
    - send the patch of "move numa global variables into MachineState"
    together with HMAT patches.
    https://lists.gnu.org/archive/html/qemu-devel/2019-04/msg03662.html
    - spilt the 1/8 of v3 patch into two patches, 4/11 introduces
    build_mem_ranges() and 5/11 builds HMAT (Igor)
    - use build_append_int_noprefix() to build parts of ACPI table in
    all patches (Igor)
    - Split 8/8 of patch v3 into two parts, 10/11 introduces NFIT
    generalizations (build_acpi_aml_common), and use it in 11/11 to
    simplify hmat_build_aml (Igor)
    - use MachineState instead of PCMachineState to build HMAT more
    generalic (Igor)
    - move the 7/8 v3 patch into the former patches
    - update the version tag from 4.0 to 4.1
v3:
    - rebase the fixing patch into the jingqi's patches (Eric)
    - update the version tag from 3.10 to 4.0 (Eric)
v2:
  Per Igor and Eric's comments, fix some coding style and small issues:
    - update the version number in qapi/misc.json
    - including the expansion of the acronym HMAT in qapi/misc.json
    - correct spell mistakes in qapi/misc.json and qemu-options.hx
    - fix the comment syle in hw/i386/acpi-build.c
    and hw/acpi/hmat.h
   - remove some unnecessary head files in hw/acpi/hmat.c 
   - use hardcoded numbers from spec to generate
   Memory Subsystem Address Range Structure in hw/acpi/hmat.c
   - drop the struct AcpiHmat and AcpiHmatSpaRange
    in hw/acpi/hmat.h
   - rewrite NFIT code to build _HMA method

Liu Jingqi (3):
  hmat acpi: Build Memory Subsystem Address Range Structure(s) in ACPI
    HMAT
  hmat acpi: Build System Locality Latency and Bandwidth Information
    Structure(s) in ACPI HMAT
  numa: Extend the command-line to provide memory latency and bandwidth
    information

Tao Xu (5):
  hw/arm: simplify arm_load_dtb
  numa: move numa global variable nb_numa_nodes into MachineState
  numa: move numa global variable have_numa_distance into MachineState
  numa: move numa global variable numa_info into MachineState
  acpi: introduce AcpiDeviceIfClass.build_mem_ranges hook
