I don't know if anymore has a interest in the 64-bit kernel, but I just
found this bug (see patch below).
It would be nice to know, how many are interested in the 64-bit kernel
and who actually got something running.
So please rise you voice.



Actually I think there is an increased interestes to 64bit kernel with the recent introduction of RM7K and bcm1250 CPUs.

If 64bit kernel gets mature, I think two years down the road we will see mid-range CPUs edging into that domain as well.
