BTW, this discussion really belongs on parisc-linux.org mailing list.
It's not specific to debian-hppa and is very kernel centric.

sorry - I don't understand the problems well enough.
The PA 2.0 arch book might describe the cache behaviors sufficiently
to determine this will be a problem.

google search for
	equivalent mapped [parisc-linux site:lists.parisc-linux.org]

yielded the original thread from Jerry Huck:

http://lists.parisc-linux.org/pipermail/parisc-linux/1999-December/008101.html

I only partially understand what Jerry talking about and have no idea
how linux VM implementation collides with the aliasing rules.


Bjorn Helgaas posted a another thread two years later that might
be more helpful since it's specific to superdome (AFAIK same problems
as with N-class and L3000):

http://lists.parisc-linux.org/pipermail/parisc-linux/2001-April/012388.html

I didn't see any direct followup to Bjorn's mail in the archive though
some discussion did occur in other forums (much later).

hth,
