Thanks Randy, got all 6 of them.

I take it that I should apply these to a 2.6.7 tarballs tree in this 
order:
1. 2.6.8-rc1
2. each of these 'rc2-bk' patches by the day and then run each for a 
couple days, or should I start in the middle, say the 3rd one and 
work forward or backwards from there depending on the results?

Your (and Viro's) call.  I'd imagine you would want to run this to 
earth as quick as we can.

Are these patches cumulative?  I presume they are as they grow by the 
day.
