instead of making another static for table_rev, why can't it be added as
an extra argument to pptt_processor_test, e.g.

static void pptt_processor_test(
	fwts_framework *fw,
	const fwts_acpi_table_pptt_processor *entry,
	const uint8_t table_rev,
	bool *passed)
{

}

..and called from pptt_test1, e.g.

               if (entry->type == FWTS_ACPI_PPTT_PROCESSOR) {
                        pptt_processor_test(fw,
(fwts_acpi_table_pptt_processor *) entry, pptt->header.revision, &passed);

			...
