Xen devel - Sep 2005 - new mfn_to_pfn() in blkfront

Hi --

An ongoing activity on the Xen/ia64 team has been
to (slowly but surely) remove the arch-dep code out
of various Xen front/back drivers.  This will
hopefully make it easier -- eventually -- to get
the Xen drivers more widely accepted for Linux.

A recent changeset (7107) added a call to mfn_to_pfn
into blkfront/blkfront.c, which had previously
been arch-neutral.  And, unfortunately, there''s no
arch-dep header file included by that file so there''s
no easy way to redefine it.  I was looking at
other ways of patching around it, but one might
consider this a regression that should be fixed.

Is there another, arch-neutral, way to write
this code?  Or at least turn it into a function
like interface?

Thanks,
Dan

Makes sense to define mfn_to_pfn() and pfn_to_mfn() as no-ops on ia64.
