2.5.70-mjb2

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 2.5.70-mjb1 (~ = changed, + = added, - = dropped)

Notes: I've left out some shiny new bits people have sent me because there
       were a few things that were just broken. Fixing those up before
       piling more on. Various floating fixes merged back into their main
       elements to make maintaince easier (possible?)

Now in Linus' tree:

New:
+ numaq_apic_handling				Martin J. Bligh
	Fix numaq code to use phys apic ids
+ remove_x86_summit				Martin J. Bligh
	remove the magic switch - genarch is better
+ target_cpus					Martin J. Bligh
	Fix up target cpus mask handling
+ backout_locking				The ghost of patches past
	dcache_lock-vs-tasklist_lock broke my box. I'm grumpy.

Dropped:
