Is there any ia64 OS routine for allocating uncacheable memory?  I am
trying to simulate the SAL/OS interface for MCA handling and the
min-state area is expected to be uncacheable.

Yep,

I have something in the works, it used to be part of the mspec driver
but I am in the process of pulling it out and making it a seperate
entity.

Currently the thing operates at page size entries only, is that
sufficient for you Keith?

Cheers,
Jes

Page size allocations are exactly what I need.
