There shouldn't be anything all that interesting in the i386 code apart from accommodations made for slab.c and pageattr.c. But yes, I can do the grunt work there since I'm familiar enough with its history. I used the i386 pagetable caching backout code to help verify that nothing unusual was going on with generic code in this area. I can debug the altered quicklist code in like fashion to what that was. Basically, I'll help all this along. -- wli -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
