I didn't get how this would fix the ia64 issues? I thought ia64 needed the standard calling convention?
My gut feel is that EFI should be handled exactly the same way that we used to handle APM: never even make it look like it's callable from C, but make architecture-specific wrapper functions that have bog-standard calling conventions, and then possibly even use inline asm to actually do the real call (but even if you don't, at that point it would be inside one particular arch-specific EFI source file - nobody outside of that would ever call into the firmware directly).
As it is, I don't think I dare apply this right now, which means that it will miss 2.6.20, and we'll have to backport it to the stable tree when everybody agrees and has acked it. I don't like having suspend broken on EFI macs, but on the other hand, I would hate to have an ia64 regression even more..
