high_memory = (void *) __va(max_low_pfn * PAGE_SIZE);
is this incorrect? It is incorrect on this specific system (Compaq 1600
dual PII 400) but is correct on some other specific system (IBM Netfinity
dual Xeon 450)
(I don't read/care about human-readable reports - I look at the value of
high_memory and it *is* incorrect (on some hardware)).
