This patchset allows the use of x86_32 percpu ops on x86_64 while maintaining %gs pointing to the pda. It does that by moving the x86_64 pda into the percpu area (thereby pointing %gs at the per cpu area) and then relocating the x86_64 per cpu variables to start at 0.
Patch applies on top of the per cpu cleanup patches V2. See http://marc.info/?l=linux-kernel&m=119628478316525&w=2 Ultimately I think we can make the per cpu accessors arch independent (see the RFC at http://marc.info/?l=linux-kernel&m=119552126330405&w=2). There is a performance benefit from using these in core code. -- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
