At OLS I gave a talk on some of the Xen scalability inhibitors, and one
of these was writable page tables. We went over why the feature does
not scale, but just as important, we found that the uniprocessor case
does not provide any advantage either. These tests were done on x86_64,
so I wanted to run the 1-way test on 32 bit to show the same problem.
So, I have run with writable PTs and

base for the patches.hg, so I took the latest (that was ~ 2 weeks ago)
kernel on git.kernel.org I could find (post-2.6.28 git tip at that
point).
I managed to more or less apply all of the patches in the
