Revision bb668da6d6f2bec8a63838c098d9515eccb22cc4 authored by Suresh Siddha on 18 January 2010, 20:10:49 UTC, committed by Linus Torvalds on 18 January 2010, 22:15:28 UTC
We can use logical flat mode if there are <= 8 logical cpu's (irrespective of physical apic id values). This will enable simplified and efficient IPI and device interrupt routing on such platforms. This has been tested to work on both Intel and AMD platforms. Exceptions like IBM summit platform which can't use logical flat mode are addressed by using OEM platform checks.
