It's meant to be pretty stable, not so much a testing ground for new stuff. I'd be very interested in feedback from anyone willing to test on any platform, however large or small. ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/2.5.63/patch-2.5.63-mjb2.bz2 additional: http://www.aracnet.com/~fletch/linux/2.5.59/pidmaps_nodepages Since 2.5.62-mjb3 (~ = changed, + = added, - = dropped) Notes: Contains some critical objrmap fixes.
