OK, these all look good, but I may only push 3/4 for Linus in this round, along with some of the changes from my patch that you tested as well.
With the DEBUG_PAGEALLOC case, I have been thinking that we perhaps should turn off the lazy unmapping optimisation as well, so it catches use after free similarly to the page allocator... but probably it is a good idea at least to avoid the double-guard page for 2.6.28?
Anyway thanks for these, I'll send them up to Andrew/Linus and cc you.
