I cleaned it up, fixed some return codes, and applied as c/s 18756. It may be worth Jan Beulich taking a quick look as the return-code conventions for the get/put functions in mm.c is now rather convoluted. I think I got it right but I'm not 100% sure. Indeed, Jan, it'd sure be nice to have some comments explaining what the <0,=0,>0 codes mean from the various get/put functions, and how they differ between the l1e variants and the others (I'm pretty sure they do differ). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
