Hi Andrew, This is a patch based on one that Jack Steiner sent to the ia64 list in November. The original thread can be found at: http://marc.theaimsgroup.com/?l=linux-ia64&m=106869606922555&w=2 I created the little wrapper function that was requested. I think the only other arch, other than ia64, that doesn't at least include asm-generic/tlb.h is arm. The patch booted fine on a 12-way Altix.
