[Qemu-devel] [PATCH v7 04/11] numa: move numa global variable numa_info into MachineState

[Tao Xu]

Move existing numa global numa_info (renamed as "nodes") into NumaState.

Suggested-by: Igor Mammedov <address@hidden>
Suggested-by: Eduardo Habkost <address@hidden>
Signed-off-by: Tao Xu <address@hidden>

No changes in v7.

Changes in v6:
    - Rebase to upstream, move globals in arm/sbsa-ref
    - Correct some mistake(Igor)
    - Use ms->numa_state->nodes directly, when use it once or twice(Igor)
