[Qemu-devel] [PULL v2 14/34] ACPI/unit-test: Add a testcase for RAM allocation in numa node

["Michael S. Tsirkin" <mst@redhat.com>]

From: Dou Liyang <douly.fnst@cn.fujitsu.com>

As QEMU supports the memory-less node, it is possible that there is
no RAM in the first numa node(also be called as node0). eg:
  ... \
  -m 128,slots=3,maxmem=1G \
  -numa node -numa node,mem=128M \

But, this makes it hard for QEMU to build a known-to-work ACPI SRAT
table. Only fixing it is not enough.

Add a testcase for this situation to make sure the ACPI table is
correct for guest.
