Re: [Linux-ia64] Status of 64K pagesize support

[Don Dugger <n0ano@valinux.com>]

Jack-

I was working on this and discovered the same two problems you ran
into.  The alignment issue isn't really a problem, turns out that
where that directive is give the code is appropriately aligned
already so just remove the line should be OK.

The bitmap in `scsi_dma.c' is the real issue and needs to be re-written
in a more general fashion.  I don't really have time to work on this
right now so if you're interested go for it.  I'd be interested in
hearing about anything you find out.
