[PATCH v7 00/13] Support PPTT for ARM64

Hi Jeremy,

ACPI 6.2 adds the Processor Properties Topology Table (PPTT), which is
used to describe the processor and cache topology. Ideally it is
used to extend/override information provided by the hardware, but
right now ARM64 is entirely dependent on firmware provided tables.

This patch parses the table for the cache topology and CPU topology.
When we enable ACPI/PPTT for arm64 we map the physical_id to the
PPTT node flagged as the physical package by the firmware.
This results in topologies that match what the remainder of the
system expects. To avoid inverted scheduler domains we then
set the MC domain equal to the largest cache within the socket
below the NUMA domain.

I remember reviewing and acknowledging most of the cacheinfo stuff with
couple of minor suggestions for v6. I don't see any Acked-by tags in
this series and don't know if I need to review/ack any more cacheinfo
related patches.
