2.6.0-test2-mjb1

The patchset contains mainly scalability and NUMA stuff, and anything 
else that stops things from irritating me. It's meant to be pretty stable, 
not so much a testing ground for new stuff.

I'd be very interested in feedback from anyone willing to test on any 
platform, however large or small.

additional patches that can be applied if desired:

Since 2.5.74-mjb1 (~ = changed, + = added, - = dropped)

Notes:  Just a merge up. Dropped a bunch o' stuff.

Now in Linus' tree:
- stacks_from_slab				William Lee Irwin
	Take kernel stacks from the slab cache, not page allocation.
- swsusp_state_check				Matt Dobson
	Fix a check in s/w suspend code
- node_spanned_pages				Dave Hansen
	Fix up NUMA beancounting

New:

Dropped:
- thread_info_cleanup (4K stacks pt 1)		Dave Hansen / Ben LaHaise
- interrupt_stacks    (4K stacks pt 2)		Dave Hansen / Ben LaHaise
- stack_usage_check   (4K stacks pt 3)		Dave Hansen / Ben LaHaise
- 4k_stack            (4K stacks pt 4)		Dave Hansen
- 4k_stacks_vs_kgdb				Dave Hansen
(will conflict with 4/4 split)
