From f1d1a842d85acf34dd185027cb2c9b4fd13130ef Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Sat, 12 May 2007 11:15:24 -0700 Subject: SLUB: i386 support SLUB cannot run on i386 at this point because i386 uses the page->private and page->index field of slab pages for the pgd cache. Make SLUB run on i386 by replacing the pgd slab cache with a quicklist. Limit the changes as much as possible. Leave the improvised linked list in place etc etc. This has been working here for a couple of weeks now.
