okay, i've picked up these patches into tip/cpus4096-v2 and started 
testing them.

I fixed the From: line oddities - please holler if they are wrong 
anywhere, we can still rebase this.

Note, i've merged this to _after_ the huge arch/x86/include/asm/ headers 
move which we sent a pull request for earlier today - this will simplify 
logistics.

( I also fixed up a handful of obvious style problems in various places
  - please be more careful about comment structure, whitespaces, etc. -
  they just distract from general review and hurt the merits of your
  patches. )

I also added "Impact:" lines to every commit - a one-line summary of the 
expected outcome of the change. (Please double-check those impact lines 
- if you see anything odd it means that i missed some detail in the 
commit - that will need to be fixed if it happens.)

I've just completed the first basic step of testing: i did 68 kernel 
builds to test bisectability: all 34 commit point builds fine on both 
64-bit and 32-bit as well. (This took some time as almost every commit 
touches cpumask.h, forcing a full kernel rebuild.)
