Hi,

attached is the promised cleanup/bugfix patch for the slab bootstrap:

Changes:
- kmem_cache_init & kmem_cache_sizes_init merged into one function, 
called after mem_init(). It's impossible to bring slab to an operational 
state without working gfp, thus the early partial initialization is not 
necessary.
- g_cpucache_up set to FULL at the end of kmem_cache_init instead of the 
module init call. This is a bugfix: slab was completely initialized, 
just the update of the state was missing.
- some documentation for the bootstrap added.

Patch against 2.5.69-mm1, tested with UP and SMP on i386 (with 
s/read_lock/spin_lock/ in filetable.c).

Andrew, what do you think? The minimal fix for the bug is a two-liner: 
move g_cpucache_up=FULL from cpucache_init to kmem_cache_sizes_init, but 
I want to get rid of kmem_cache_sizes_init, too.
