Be prepared to be flamed for that on lkml, using /proc for stuff like
that (i.e. driver specifix settings) is depricated these days.  It
should go to sysfs instead.

I can come up with a patch for that, might take some days though as
I'm busy with some non-xen stuff at the moment.



btw: can whoever runs the changelog list (rik?) please add the
repository (2.0, unstable, ...) to to subject line please?  And while
you are at it: -p1 for the diffstat would be cool as well, especially
for one-file commits, there are -- for example -- plenty of page.h
files in the tree.  Thanks.
