Well, I do not know, either. But if I have to guess, it might mean that
"acpi_table_init() is separated from acpi_boot_init() to allow reading
SRAT without the conditional flags, ex. acpi_lapic and acpi_ioapic, in
acpi_boot_init()."
I'd suggest you simply rephrase it to match with your change, instead of
trying to keep such old history.
