When PAGE_MMUCOUNT > 1, the pgd : struct page relation becomes N:1, so that pgd_ctor() and pgd_dtor() may be called multiple times for each page dedicated to the pgd slab. The bug was that pgd_ctor() did an unconditional list_add(&page->lru, &pgd_list) and pgd_dtor() did an unconditional list_del(&page->lru, &pgd_list) regardless of whether the page backing the pgd's passed as an argument was already on the pgd_list. There was also a bug in pageattr.c where the pieces of a pgd slab page weren't iterated over when looping over pgd slab pages. A minor highmem compilefix and a fixes for /proc/vmstat reporting inaccuracies are also included. pgcl-2.5.70-bk5-2 survives a couple of hours of running dbench and tiobench in a loop. Available as an incremental patch atop pgcl-2.5.70-bk5-1 from: ftp://ftp.kernel.org/pub/linux/kernel/people/wli/vm/pgcl/ -- wli
