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 Memory Proximity Domain.
The software is expected to use HMAT information as hint for optimization.

In the linux kernel, the codes in drivers/acpi/hmat/hmat.c parse and report
the platform's HMAT tables.

The V13 patches link:
https://patchwork.kernel.org/cover/11200909/

Changelog:
v14:
    - Reuse the codes of do_strtosz to build qemu_strtotime_ns
      (Eduardo)
    - Squash patch v13 01/12 and 02/12 together (Daniel and Eduardo)
    - Drop time unit picosecond (Eric)
    - Use qemu ctz64 and clz64 instead of builtin function
v13:
    - Modify some text description
    - Drop "initiator_valid" field in struct NodeInfo
    - Reuse Garray to store the raw bandwidth and bandwidth data
    - Calculate common base unit using range bitmap
    - Add a patch to alculate hmat latency and bandwidth entry list
    - Drop the total_levels option and use readable cache size
    - Remove the unnecessary head file
    - Use decimal notation with appropriate suffix for cache size
v12:
    - Fix a bug that a memory-only node without initiator setting
      doesn't report error. (reported by Danmei Wei)
    - Fix a bug that if HMAT is enabled and without hmat-lb setting,
      QEMU will crash. (reported by Danmei Wei)
v11:
    - Move numa option patches forward.
    - Add num_initiator in Numa_state to record the number of
    initiators.
    - Simplify struct HMAT_LB_Info, use uint64_t array to store data.
    - Drop hmat_get_base().
    - Calculate base in build_hmat_lb().
v10:
    - Add qemu_strtotime_ps() to convert strings with time suffixes
    to numbers, and add some tests for it.
    - Add qapi buildin type time, and add some tests for it.
    - Add machine oprion properties "-machine hmat=on|off" for
	  enabling or disabling HMAT in QEMU.

Hi,

This series failed the docker-quick@centos7 build test. Please find the testing commands and
their output below. If you have Docker installed, you can probably reproduce it
locally.
