I'm afraid you are wrong. Eariler kernel are affected as well. At reading your mail I was
thinking of applying those two patches to 2.6.24-rc5 and do bisection on the rest of -mm series.
Unfortunately clean 2.6.24-rc5 with these two patches is affected as well (new processes
stuck in D state etc). So I tried vanilla 2.6.23 patched by these two patches (and
mem_lseek export from fs/proc/base.c). Now at least I got a trace produced by 'cat /proc/kpagecount'
which you can find below. Also, in spite of the oops, the box doesn't get locked (as with -mm)
and is still usable.
