I've not seen any update to them from their original version (i.e. when they were first discussed). Is this correct?
I guess, you're talking about my SYSEMU_SINGLESTEP patches. Since I created two patches each for 2.6.9 and 2.6.7, you should have these four patches:
../tmp/patch-2.6.7-skas-v7-reorganize ../tmp/patch-2.6.7-skas-v7-add-SYSEMU_SINGLESTEP
../tmp/patch-2.6.9-skas-v7-reorganize ../tmp/patch-2.6.9-skas-v7-add-SYSEMU_SINGLESTEP
On my system, the change date is Nov 12. So, I guess the ones you have still are up to date.
But on my 2.6.9, I added a further patch to catch some rare conditions, when doing sysaudit together with ptracing, or switching between different ptrace commands. I don't know, if I ever sent it to the list. IIRC, uml runs fine without it (but IMHO, we should use the more "complete" solution). The sysaudit/ptrace issue is a general problem for i386, too.
Have attached a tarball containing all five patches.
