Hi Peter,

Well, now that Roland has made at least one of the PARISC maintainers
aware of the problem, we could wait a little while to see if a solution
is forthcoming from them.  If not, then maybe Roland's patch could be
applied to the appropriate tip tree or we could just leave PARISC broken
in linux-next until they decide to fix it.  Note that some of the PARISC
builds are already broken in linux-next for other reasons.

Are there any downsides to Roland's patch as far as PARISC is concerned
(apart from the loss of some functionality, of course)?
