Hi Jeremy,
Few nits below.
Also, I had a look at the other PPTT processor flags that were introduced
in 6.3, and the only other one being used is ACPI_LEAF_NODE in
acpi_pptt_leaf_node(). However that one already has a handle on the table
header, so the check_acpi_cpu_flag() isn't of much help the
ACPI 6.3 adds a flag to the CPU node to indicate whether
the given PE is a thread. Add a function to return that
information for a given linux logical CPU.
