Subject: Fix SLAB kmem_list3 for booting on machines with memoryless nodes
(full revert of 04231b3002ac53f8a64a7bd142fde3fa4b6808c6)
From: Mel Gorman <[EMAIL PROTECTED]>
Complete the revert of the changes made by
04231b3002ac53f8a64a7bd142fde3fa4b6808c6 to the kmem_list3 management in slab.
On a machine with a memoryless node, BUG_ONs are triggering related to lists
not being initialised and this affects 2.6.24 so should be considered a
candidate for the stable tree. The intention was to fully revert with commit
9c09a95cf431fcf5720f2e408befa24b32b8cf4d but I mucked it up.
This patch partially addresses a problem in 2.6.24 where SLAB in use with a
machine with memoryless nodes fails to boot. SLUB is not affected. Pekka
Enberg has the remainder of the fix which alters when the lists are
initialised.
